VOC results are qualified as J/Estimated. The following results are qualified (pending the results of the blank evaluation).

Sample ID Qualified VOCs (ug/L)

EPA-MW11A Chloroform = 0.52 J EPA-MW11A PCE = 0.46 J DUP001 Chloroform = 0.16 J

3) Results from two full suite method blanks were provided in association with the groundwater sample analyses. Acetone was detected in the method blank from batch 12I0648 at an estimated concentration of 4.99 ug/L. Acetone was not detected in any of the associated samples, and no action is required.

One trip blank was analyzed, with no VOCs detected. Results from one equipment blank were provided, with no VOCs detected.

4-5) TestAmerica provided results from two full sets of laboratory control sample (LCS) and LCS duplicate (LCSD) analyses in support of the groundwater sample analyses. Precision and accuracy, as demonstrated by these analyses is acceptable, with the following exception. The trichlorofluoromethane recovery in one LCS was high at 126 percent (upper control limit of 123 percent). Trichlorofluoromethane was not detected in any of the associated samples, and no action is required.

6-7) TestAmerica provided results from one set of project specific MS and MSD analyses

(spike on project sample EPA-MW11A), and from one set of batch specific MS and MSD analyses in support of the VOC analyses. Precision and accuracy, as demonstrated by these analyses is acceptable.

8) Three surrogates were spiked into each groundwater sample in support of the VOC

analyses. Surrogate recoveries were acceptable, ranging from 93 to 111 percent. 9) Sample DUP001 was submitted as a blind field duplicate of primary sample

EPA-MW58A. Precision between the duplicate sample results, measured as the relative percent difference (RPD) between the primary and duplicate sample results, is calculated in the following table. Results are presented in micrograms per liter (ug/L).

10) Results from several bromofluorobenzene instrument tunes were provided in

support of all sample analyses and calibrations. Frequency of tunes was acceptable for each analytical batch at 12 hours or less between tunes. Ion abundance criteria for each of the tunes were acceptable.

11) Results were provided from two initial calibrations associated with the VOC

analyses in this SDG. One calibration is dated July 9, 2012 (GCMS#4), and the other is dated September 18, 2012 (GCMS#9).

The July 9, 2012 initial calibration is associated with the following samples:

TB001-09142012 EPA-MW2C-09142012 EPA-MW19C-09142012 EPA-MW4C-09142012 EPA-MW8C-09142012

The calibration was a 9-point calibration analyzed at the following concentrations (0.5, 1.0 2.0, 5.0, 10, 25, 50, 100, and 200 ug/L). Average Relative Response Factors (RRFs) were greater than 0.05 for all VOC short list target compounds. Low end standards for acetone (three) and 2-butanone (two) were omitted in order to improve response factors. Percent relative standard deviations (%RSDs) were reported when quantitation was based on average response factors. %RSDs reported for target short list VOCs were acceptable and less than 30 percent for all VOCs. Linear calibrations were performed for VOCs with RSDs greater than 15 percent. For the project short list, methylene chloride, trans-1,2-DCE, cis-1,2-DCE, and 1,1,1-TCA were quantified from linear calibrations. The correlation coefficients for these calibrations were acceptable at 0.995 or greater. A 25 ug/L second source calibration standard was analyzed on July 9, 2012. All second source recoveries for the short list target VOCs were within prescribed control limits.

The September 18, 2012 calibration is associated with the following samples:

EPA-MW11A-09142012 EPA-MW58A-09142012

DUP001-09142012 EB001-09142012 The calibration was a 9-point calibration analyzed at the following concentrations (0.5, 1.0 2.0, 5.0, 10, 25, 50, 100, and 200 ug/L). Average Relative Response Factors (RRFs) were greater than 0.05 for all VOC short list target compounds, with the exception of 2-butanone at 0.037. 2-Butanone was not detected in any of the associated samples. Due to the low calibration response, 2-butanone results for the samples listed above are qualified as R/Rejected. Low end

standards for acetone (three) and 2-butanone (two) were omitted in order to improve response factors. Percent relative standard deviations (%RSDs) were reported when quantitation was based on average response factors. %RSDs reported for target short list VOCs were acceptable and less than 30 percent for all VOCs. Linear calibrations were performed for VOCs with RSDs greater than 15 percent. For the project short list, methylene chloride was quantified from a linear calibration. The correlation coefficient for this calibration was acceptable at 0.999. A 25 ug/L second source calibration standard was analyzed on September 18, 2012. All second source recoveries for the short list target VOCs were within prescribed control limits.

12) TestAmerica provided results from two sets of continuing calibration verification

(CCV) standard analyses. Both CCVs are dated September 18, 2012. The CCVs are distinguished by the ICAL date and the GCMS instrument number.

September 18, 2012 (GCMS-#9) - This CCV is associated with the all groundwater samples in this SDG analyzed on instrument GCMS #9 under the September 18, 2012 initial calibration Results from one CCV were provided at the 25 ug/L level. The percent differences (%D) between the response factors in the initial calibration and the continuing calibration were less than 25 percent. All CCV recoveries were within prescribed control limits. Response factors for all target VOCs in the CCV were greater than 0.05, with the exception of that for 2-butanone at 0.044. 2-Butanone results are already qualified due to the initial calibration. September 18, 2012 (GCMS-#4) - This CCV is associated with the all groundwater samples in this SDG analyzed on instrument GCMS#4 under the July 9, 2012 initial calibration Results from one CCV were provided at the 25 ug/L level. The percent differences (%D) between the response factors in the initial calibration and the continuing calibration were less than 25 percent. All CCV recoveries were within prescribed control limits. Response factors for all target VOCs in the CCV were greater than 0.05.

13) Three internal standards were reported for each sample analyzed. Standard areas (responses) were within –50 and +100 percent of the associated standard. Retention times were within 30 seconds of the associated standard.

14) Results for tentatively Identified Compounds (TICs) were not required for the

PGAN investigation.

15) TestAmerica provided results of all appropriate run logs shown analytical sequences of standards and samples.

16) Reconstructed ion chromatograms were reviewed for each of the samples in this SDG.

Chromatographic peaks were verified for each VOC reported as detected. Retention times were verified against quantitation reports for each of the detections. Quantitation reports were reviewed for each of the samples. Concentrations were verified against the Form I data reports for all detections and were found to be consistent for each sample.

4) Results from continuing calibration analyses are described in note #9. 5-6) TestAmerica provided results from one set of project specific MS and MSD

analyses in support of the perchlorate analyses (spike on project sample EPA-MW2C). Precision and accuracy, as demonstrated by these analyses is acceptable. MS and MSD recoveries were each 91 percent, with an RPD between MS and MSD recoveries of 0.5 percent.

7) TestAmerica provided results from one set of LCS and LCS duplicate analyses in

support of the perchlorate analyses. Precision and accuracy, as demonstrated by these analyses is acceptable. Aqueous LCS recoveries were 92 and 102 percent. The RPD between LCS and LCSD results was acceptable at 11 percent.

8) Field duplicate samples were not collected with this chain-of-custody in support of

the perchlorate analyses.

TestAmerica provided results from one set of project specific laboratory duplicate sample analyses (duplicate of project sample EPA-MW8C). Laboratory duplicate precision is acceptable, as the results are in agreement within a reporting limit increment (the RPD of 43 percent is not evaluated in this situation).

9) Results from one 5-point initial calibration (standard levels of 2 ug/L, 5 ug/L, 10

ug/L, 25 ug/L, and 50 ug/L) dated May 29, 2012 were provided. The correlation coefficient for the calibration was acceptable at 0.9994. A mid range initial performance check (IPC) standard (25 ug/L) was analyzed following the initial calibration with an acceptable recovery of 93.2 percent

The calibration was a 9-point calibration analyzed at the following concentrations (0.5, 1.0 2.0, 5.0, 10, 25, 50, 100, and 200 ug/L). Average Relative Response Factors (RRFs) were greater than 0.05 for all VOC short list target compound, with the exception of 2-butanone at 0.028. 2-Butanone was not detected in any of the associated samples. Due to the low initial calibration response, all 2-butanone sample results are qualified as R/Rejected. Low end standards for acetone (four) and 2-butanone (two) were omitted in order to improve response factors. Percent relative standard deviations (%RSDs) were reported when quantitation was based on average response factors. %RSDs reported for target short list VOCs were acceptable and less than 30 percent for all VOCs. Linear calibrations were performed for VOCs with RSDs greater than 15 percent. For the project short list, no linear calibrations were required. A 25 ug/L second source calibration standard was analyzed on September 24, 2012. All second source recoveries for the short list target VOCs were within prescribed control limits.

12) TestAmerica provided results from one set of continuing calibration verification

(CCV) standard analyses dated September 25, 2012. The September 25, 2012 CCV is associated with all groundwater samples analyzed under this SDG.

4-5) TestAmerica provided results from two sets of laboratory control sample (LCS) and

LCS duplicate (LCSD) analyses in support of the groundwater VOC analyses. Precision and accuracy, as demonstrated by these analyses is acceptable.

6-7) TestAmerica provided results from one set of project specific MS and MSD analyses

(spike on project sample EPA-MW35A), and from one set of batch specific MS and MSD analyses in support of the VOC analyses. Precision and accuracy, as demonstrated by these analyses is acceptable for all VOCs, with the following exceptions. MSD recoveries in the project spike were high for cis-1,2-DCE, TCE, and trichlorofluoromethane. No action is required, as the associated LCS recoveries for these VOCs demonstrated acceptable accuracy.

8) Three surrogates were spiked into each groundwater sample in support of the VOC

analyses. Surrogate recoveries ranged from 102 to 129 percent, and were within prescribed control limits, with the following exceptions. The toluene-d8 surrogate was slightly high in the following samples (upper control limit of 111 percent):

Sample ID High Toluene-D8 Surrogate

GCLake 112 % MW15 112 % EPA-MW62A 113 % DUP002 113 % EPA-MW23A 112 %

No action is taken, for the slightly high surrogate recoveries at 112 percent, given a 1 percent allowance for rounding issues. VOCs detections in undiluted analyses for samples EPA-MW26A and it duplicate DUP002 are qualified as J/Estimated due to potential high bias. No additional data are qualified as all detections are either between the MDL and RL, or a qualified due to blank contamination.

9) Two sets of field duplicate samples were collected in support of the VOC analyses.

Sample DUP001 was submitted as a field duplicate of primary sample MW16. TCE was detected in the primary and duplicate samples at concentrations of 15 ug/L, each. Precision between TCE results is acceptable, with an RPD of 0 percent. Chloroform was detected in both samples at estimated concentrations between the MDL and RL. Chloroform is qualified due to equipment blank contamination, and is not further assessed in the precision evaluation.

Sample DUP002 was submitted as a field duplicate of primary sample EPA-MW62A. Precision between the duplicate sample results, measured as the relative percent difference (RPD) between the primary and duplicate sample results, is calculated in the following table. Results are presented in micrograms per liter (ug/L).

10) Results from several bromofluorobenzene instrument tunes were provided in support of all sample analyses and calibrations. Frequency of tunes was acceptable for each analytical batch at 12 hours or less between tunes. Ion abundance criteria for each of the tunes were acceptable.

11) Results were provided from one initial calibration associated with the VOC

analyses in this SDG, dated September 27, 2012 (GCMS#9). The September 27, 2012 initial calibration is associated with analysis of all groundwater samples in this SDG. The calibration was a 9-point calibration analyzed at the following concentrations (0.5, 1.0 2.0, 5.0, 10, 25, 50, 100, and 200 ug/L). Average Relative Response Factors (RRFs) were greater than 0.05 for all VOC short list target compounds. Low end standards for acetone (three) and 2-butanone (three) were omitted in order to improve response factors. Percent relative standard deviations (%RSDs) were reported when quantitation was based on average response factors. %RSDs reported for target short list VOCs were acceptable and less than 30 percent for all VOCs. Linear calibrations were performed for VOCs with RSDs greater than 15 percent. For the project short list, no linear calibrations were required. A 25 ug/L second source calibration standard was analyzed on September 27, 2012. All second source recoveries for the short list target VOCs were within prescribed control limits.

Methylene chloride was not detected in any associated samples, and no action is required. TCE was detected in sample EPA-MW21A at a concentration within two times that of the equipment blank. Due to potential blank contamination bias, this TCE results is qualified as U/non-detect at the concentration reported.

4-5) TestAmerica provided results from one full set of laboratory control sample (LCS)

and LCS duplicate (LCSD) analyses in support of the groundwater sample analyses. Precision and accuracy, as demonstrated by these analyses is acceptable.

6-7) TestAmerica provided results from one set of project specific MS and MSD analyses

(spike on project sample EPA-MW19C) in support of the VOC analyses. Precision and accuracy, as demonstrated by these analyses is acceptable.

8) Three surrogates were spiked into each groundwater sample in support of the VOC

analyses. Surrogate recoveries were acceptable, ranging from 97 to 110 percent. 9) Sample DUP001-10122012 was submitted as a blind field duplicate of primary

sample EPA-MW62A. TCE was detected in the primary and duplicate samples at concentrations of 150 ug/L, each. Precision between the duplicate TCE results is acceptable, with an RPD of 0 percent.

10) Results from several bromofluorobenzene instrument tunes were provided in support of all sample analyses and calibrations. Frequency of tunes was acceptable for each analytical batch at 12 hours or less between tunes. Ion abundance criteria for each of the tunes were acceptable.

11) Results were provided from one initial calibration associated with the VOC

analyses in this SDG. The initial calibration is dated October 15, 2012 (GCMS#2). The October 15, 2012 initial calibration is associated with analysis of all groundwater samples in this SDG. The calibration was a 9-point calibration analyzed at the following concentrations (0.5, 1.0 2.0, 5.0, 10, 25, 50, 100, and 200 ug/L). Average Relative Response Factors (RRFs) were greater than 0.05 for all VOC short list target compounds, with the exception of 2-butanone at 0.033. 2-Butanone was not detected in any of the associated samples. Due to the poor calibration response, 2-butanone results for this SDG are qualified as R/Rejected. Low end standards for acetone (four) and 2-butanone (one) were omitted in order to improve response factors. Percent relative standard deviations (%RSDs) were reported when quantitation was based on average response factors. %RSDs reported for target short list VOCs were acceptable and less than 30 percent for all VOCs. Linear calibrations were performed for VOCs with RSDs greater than 15 percent. For the project short list, acetone was quantified from a linear calibration. The correlation coefficient for acetone was acceptable at 0.997. A 25 ug/L second source calibration standard was analyzed on October 15, 2012. All second source recoveries for the short list target VOCs were within prescribed control limits. A 20 ug/L second source calibration gas standard was analyzed on October 15, 2012. All second source recoveries for the short list target VOCs were within prescribed control limits.

12) TestAmerica provided results from one set of continuing calibration verification

(CCV) standard analyses dated October 16, 2012. The October 16, 2012 CCV is associated with all groundwater samples analyzed under this SDG.

continuing calibration were less than 25 percent. All CCV recoveries were within prescribed control limits. Response factors for all target VOCs in the CCV were greater than 0.05, with the exception of that for 2-butanone at 0.030. 2-Butanone results are already qualified due to poor initial calibration response.

13) Three internal standards were reported for each sample analyzed. Standard areas (responses) were within –50 and +100 percent of the associated standard. Retention times were within 30 seconds of the associated standard.

14) Results for tentatively Identified Compounds (TICs) were not required for the

PGAN investigation. 15) TestAmerica provided results of all appropriate run logs shown analytical

sequences of standards and samples. 16) Reconstructed ion chromatograms were reviewed for each of the samples in this

SDG. Chromatographic peaks were verified for each VOC reported as detected. Retention times were verified against quantitation reports for each of the detections. Quantitation reports were reviewed for each of the samples. Concentrations were verified against the Form I data reports for all detections and were found to be consistent for each sample.

2) No sample dilutions were required to quantitate any VOCs. All reporting limits are acceptable with the following considerations. Some VOCs were reported at concentrations between the method detection limit (MDL) and the reporting limit. Due to limited accuracy in this portion of the calibration range, these VOC results are qualified as J/Estimated. The following results are qualified (pending the results of the blank evaluation).

Sample ID Qualified VOCs (ug/L) EPA-MW44A Chloroform = 0.72 J

MW17 Chloroform = 0.68 J

EPA-MW20A PCE = 0.49 J EPA-MW37A Chloroform = 0.46 J 3) Results from five full suite method blanks were provided in association with the

groundwater sample analyses. No VOCs were detected in any of the method blanks.

Results from one trip blank were provided, with no VOCs detected. Results from two equipment blanks were provided. Methylene chloride was detected in the equipment blank collected on November 15, 2012 at a concentration of 2.4 ug/L. Methylene chloride was not detected in any of the associated samples, and no action is required.

4-5) TestAmerica provided results from five full sets of laboratory control sample (LCS) and LCS duplicate (LCSD) analyses in support of the groundwater sample analyses. Precision and accuracy, as demonstrated by these analyses is acceptable, with the following exceptions. Precision between LCS and LCSD recoveries for acetone and 2-butanone was poor, with RPDs of 43 percent and 34 percent, respectively in one LCS set (project precision control limit of 25 percent). Precision between LCS and LCSD recoveries for acetone was poor, with RPDs of 37 and 28 percent in two other LCS sets. Acetone and 2-butanone were not detected in the associated samples, and no bias to the sample results is indicated.

6-7) TestAmerica provided results from one set of project specific MS and MSD analyses

(spike on project sample EPA-MW44A), and from four sets of batch specific MS and MSD analyses in support of the VOC analyses. Precision and accuracy, as demonstrated by these analyses is acceptable, with one exception. The MS recovery for 1,1,2,2-tetrachloroethane was high in one batch spike at 130 percent (upper control limit of 124 percent). 1,1,2,2-Tetrachloroethane was not detected in any of the associated samples, and no action is required.

8) Three surrogates were spiked into each groundwater sample in support of the VOC

analyses. Surrogate recoveries ranged from 109 to 128 percent. Numerous 4-

MW23 1,1-DCE = 0.45 J MW06 Chloroform = 0.25 J MW04 1,1-DCE = 0.24 J EPA-MW1M TCE = 0.31 J EPA-MW7A Chloroform = 0.47 J

3) Results from four full suite method blanks were provided in association with the groundwater sample analyses. No VOCs were detected in the method blanks. Results from one trip blank were provided, with no VOCs detected. Results from two equipment blanks were provided. No VOCs were detected in the equipment blanks.

4-5) Accutest provided results from four full sets of laboratory control sample (LCS) and

LCS duplicate (LCSD) analyses (identified as blank spike analyses) in support of the groundwater sample analyses. Precision and accuracy, as demonstrated by these analyses is acceptable.

6-7) Accutest provided results from two full sets of project specific MS and MSD analyses

(spikes on project samples EPA-MW57A and EPA-MW3C), and from two sets of batch specific MS and MSD analyses in support of the VOC analyses. Precision and accuracy, as demonstrated by these analyses, are acceptable, with the following exceptions. The MS recovery for TCE in the project spike of sample EPA-MW3C was high 187 percent. TCE precision for this spike was also poor, with an RPD of 29 percent. The TCE concentration in the sample spiked was more than 3 times higher than the spike added amount, and no action is required.

8) Three surrogates were spiked into each groundwater sample in support of the VOC

analyses. Surrogate recoveries were acceptable, ranging from 89 to 110 percent. 9) Two sets of blind field duplicate samples were submitted with the sample under this

chain-of-custody. Sample DUP001-11132012 was submitted as a blind field duplicate of primary sample MW02. TCE was detected in the primary and duplicate samples at

The samples were analyzed by November 14, 2012, within the prescribed 14-day holding time for preserved VOCs in groundwater.

2) Samples EPA-MW47C, EPA-MW47A, PZ01 and DUP002 were diluted by

factors of 10 times for TCE only. Sample EPA-MW13A was diluted by factor of 20 times for TCE only. No other sample dilutions were required to quantitate any VOCs. All reporting limits are acceptable with the following considerations. Some VOCs were reported at concentrations between the method detection limit (MDL) and the reporting limit. Due to limited accuracy in this portion of the calibration range, these VOC results are qualified as J/Estimated. The following results are qualified (pending the results of the blank evaluation).

6-7) ESC Laboratory provided results from three sets of project specific MS and MSD

analyses (spikes on project samples EPA-MW12A, EB001-11052012 and EB001-11-62012), and from two sets of batch specific MS and MSD analyses. Two additional set of batch specific MS and MSD analyses were performed for TCE only. Precision and accuracy, as demonstrated by these analyses is acceptable, with the following exceptions. The 1,1,2,2-tetrachloroethane MS and MSD recoveries were high in the project spike of sample EPA-MW12A spike at 194 percent and 200 percent (upper control limit of 149 percent). No action is required, as 1,1,2,2-tetrachloroethane was not detected in any of the associated samples.

8) Three primary surrogates, and one alternate surrogate, were spiked into each

groundwater sample in support of the VOC analyses. All surrogate recoveries were within prescribed control limits, ranging from 90.9 to 119 percent.

9) Two sets of blind field duplicate samples were submitted with the samples under this

chain-of-custody. Sample DUP001-11072012 was submitted as a blind field duplicate of primary sample MW24. No VOCs were detected in either of the samples. Field duplicate precision is determined to be acceptable.

Sample DUP002-11072012 was submitted as a blind field duplicate of primary

sample PZ01. Precision between the duplicate sample results, measured as the relative percent difference (RPD) between the primary and duplicate sample results, is calculated in the following table. Results are presented in micrograms per liter (ug/L).

water samples were received at an acceptable temperature of 3.1 degrees on wet ice. Holding times for perchlorate are 28 days. All perchlorate analyzes were performed by November 20, 2012, within prescribed holding times.

2) All groundwater samples were analyzed at 5 times dilutions, except for samples

EPA-MW47C, EPA-MW47A, EPA-MW13A and EB01 (10 times); and MW10 and OWC (2 times). Reporting limits are determined to be acceptable, with the following considerations. Perchlorate was only detected in one of the sample analyzed (PZ-01). The five fold dilution results in a reporting limit of 2.5 ug/L, which is similar to the 2.0 ug/L reporting limit used by TestAmerica for undiluted samples. The laboratory noted matrix interference for all samples analyzed at dilutions, where no perchlorate was detected.

3) Results from three method blanks were provided in support of the groundwater sample

analyses with no perchlorate detected. Results from four equipment blanks were also provided. Perchlorate was not detected in any of the equipment blanks.

4) Results from continuing calibration analyses were not provided. 5-6) ESC Laboratory provided results from two sets of project specific MS and MSD

analyses (spikes on project samples EPA-MW12A and EB001-11072012), and from one batch MS and MSD set in support of the perchlorate analyses. MS and

MSD recoveries ranged from 43 percent to 145 percent, with a maximum RPD between MS and MSD recoveries of 28 percent. MS recoveries were low for the project spike of sample EPA-MW12A at 43 and 52 percent (lower laboratory control limit of 80 percent). MS and MSD recoveries for the batch spike analyzed in the same analytical batch were high at 130 percent and 140 percent (upper control limit of 120 percent). The MS recovery for the spike of the equipment blank were high at 145 percent and precision was poor with an RPD of 28 percent (project precision control limit of 25 percent maximum). Due to the poor precision and accuracy demonstrated by the MS and MSD results, and low bias shown by the groundwater project spike, all perchlorate results are qualified as UJ/Estimated and non-detect at the reporting limits stated. for non-detects, and J/Estimated for the detection in sample PZ01.

7) ESC Laboratory provided results from three sets of LCS and LCSD analyses in

support of the perchlorate analyses. Precision and accuracy, as demonstrated by these analyses is acceptable. Aqueous LCS and LCSD recoveries ranged from 90.8 to 109 percent, with a maximum RPD of 0.9 percent between LCS duplicate results.

8) Sample DUP002-1107 was submitted as a blind field duplicate of primary sample

PZ01. Perchlorate was detected in the primary sample at 6.7 ug/L and was not detected in the duplicate sample at <2.5 ug/L. Precision between the perchlorate duplicate sample results is very poor, with an RPD of at least 91 percent. Due to the poor field duplicate precision, perchlorate results for the primary and duplicate samples are qualified as J/Estimated.

ESC Laboratory provided results from four sets of project specific laboratory

duplicate sample analyses, performed on project samples EB001-11052012, EB001-11062012, EPA-MW26A and EB002-11082012. The laboratory duplicate precision is acceptable. No perchlorate was detected in any of the samples. Laboratory duplicates of equipment blanks do not provide significant information.

9) No anomalies were noted with respect to the perchlorate reporting.

3) Results from two full suite method blanks were provided in association with the groundwater sample analyses. No VOCs were detected in the method blanks.

Results from one trip blank were provided. No VOCs were detected in the trip blank.

4-5) TestAmerica provided results two full sets of laboratory control sample (LCS) and LCS duplicate (LCSD) analyses in support of the groundwater VOC analyses. Precision and accuracy, as demonstrated by these analyses is acceptable, with the following exceptions. For batch 12K0522, the LCSD recovery for 1,1,2,2-tetrachloroethane was high at 131 percent (upper limit of 125 percent). No action is required, as 1,1,2,2-tetrachloroethane was not detected in any associated samples. For batch 12K0523, the LCS recovery for trichlorofluoromethane was high at 126 percent (upper limit of 123 percent). No action is required, as trichlorofluoromethane was not detected in any associated samples.

6-7) TestAmerica provided results from one set of project specific MS and MSD analyses

(spike on project sample EA05-EFF), and from one set of batch specific MS and MSD analyses, in support of the VOC analyses. Precision and accuracy, as demonstrated by these analyses are acceptable, with the following exceptions. For the batch spike, MS/MSD recoveries were low for m/p-xylenes and ethylbenzene. No action is required, as acceptable precision and accuracy for these VOCs is demonstrated by the results of the LCS and LCSD analyses. MS and MSD recoveries for the project spike are in control.

8) Three surrogates were spiked into each groundwater sample in support of the VOC

analyses. Surrogate recoveries ranged from 106 to 124 percent. Numerous 4-bromofluorobenzene (4-BFB) surrogates were high, exceeding the 114 percent upper project control limit. Some toluene-d8 surrogate recoveries were also high, exceeding the 111 percent upper control limit, as follows:

Methylene chloride was detected in the equipment blank collected on November 15, 2012 at a concentration of 2.4 ug/L. Methylene chloride was not detected in any of the associated samples, and no action is required.

4-5) TestAmerica provided results from five full sets of laboratory control sample (LCS) and LCS duplicate (LCSD) analyses in support of the groundwater sample analyses. Precision and accuracy, as demonstrated by these analyses is acceptable, with the following exceptions. Precision between LCS and LCSD recoveries for acetone and 2-butanone was poor, with RPDs of 43 percent and 34 percent, respectively in one LCS set (project precision control limit of 25 percent). Precision between LCS and LCSD recoveries for acetone was poor, with RPDs of 37 and 28 percent in two other LCS sets. Acetone and 2-butanone were not detected in the associated samples, and no bias to the sample results is indicated.

6-7) TestAmerica provided results from one set of project specific MS and MSD analyses

(spike on project sample EPA-MW44A), and from four sets of batch specific MS and MSD analyses in support of the VOC analyses. Precision and accuracy, as demonstrated by these analyses is acceptable, with one exception. The MS recovery for 1,1,2,2-tetrachloroethane was high in one batch spike at 130 percent (upper control limit of 124 percent). 1,1,2,2-Tetrachloroethane was not detected in any of the associated samples, and no action is required.

8) Three surrogates were spiked into each groundwater sample in support of the VOC

analyses. Surrogate recoveries ranged from 109 to 128 percent. Numerous 4-bromofluorobenzene (4-BFB) surrogates were high, exceeding the 114 percent upper project control limit. Several toluene-d8 surrogate recoveries were also high, exceeding the 111 percent upper control limit, as follows:

COMMENTS: Performance was acceptable, with the following exceptions and/or notes. 1) The water samples were received chilled at an acceptable temperature of 0.4

degrees Celsius on wet ice (no samples were frozen). The groundwater samples were properly preserved with hydrochloric acid at the time of collection on November 16, 2012. The samples were analyzed by November 21, 2012, within the prescribed 14-day holding time for preserved VOCs in groundwater.

2) No sample dilutions were required to quantitate any VOCs. All reporting limits

are acceptable with the following considerations. Some VOCs were reported at concentrations between the method detection limit (MDL) and the reporting limit. Due to limited accuracy in this portion of the calibration range, these VOC results are qualified as J/Estimated. The following results are qualified (pending the results of the blank evaluation).

One trip blank was analyzed, with no VOCs detected. Results from one equipment blank were provided. Methylene chloride was detected in the equipment blank at a concentration of 2.4 ug/L. Methylene chloride was not detected in any associated samples, and no action is required.

4-5) TestAmerica provided results from one full set of laboratory control sample (LCS) and LCS duplicate (LCSD) analyses in support of the groundwater sample analyses. Precision and accuracy, as demonstrated by these analyses is acceptable, with one exception. Precision between LCS and LCSD recoveries was poor for acetone with an RPD of 28 percent. No action is taken, as acetone was not detected in any associated samples, and no bias to the acetone results is indicated.

6-7) TestAmerica provided results from one set of project specific MS and MSD analyses

(spike on project sample EPA-MW36A) in support of the VOC analyses. Precision and accuracy, as demonstrated by these analyses is acceptable for all VOCs.

8) Three surrogates were spiked into each groundwater sample in support of the VOC

analyses. Surrogate recoveries ranged from 111 to 126 percent. Numerous 4-bromofluorobenzene (4-BFB) surrogates were high, exceeding the 114 percent upper project control limit. Several toluene-d8 surrogate recoveries were also high, exceeding the 111 percent upper control limit, as follows:

4-5) TestAmerica provided results from three full sets of laboratory control sample (LCS)

and LCS duplicate (LCSD) analyses in support of the groundwater sample analyses. Precision and accuracy, as demonstrated by these analyses is acceptable, with the following exceptions. The LCS for PCE was low at 83 percent (lower control limit of 85 percent) in batch 12K1134. PCE was not detected in the associated samples. Due to potential low bias, the following samples are qualified as “UJ/Estimated and non-detect at the reporting limits stated,” for PCE.

LPW894-11202012 EPA-MW22C-11202012 EPA-MW55A-11202012 EPA-MW39C-11202012 EPA-MW39A-11202012 EPA-MW45A-11202012 EPA-MW16C-11202012 EPA-MW35A-11202012

Precision between LCS and LCSD recoveries for acetone was poor in the same batch, with an RPD of 27 percent (upper control limit of 25 percent). No bias to the acetone results is indicated. The o-xylene LCSD recovery was high at 118 percent in the spike from batch 12K1135. The trichlorofluoromethane LCSD recovery was high at 129 percent (upper control limit of 123 percent) in the spike from batch 12K0036. Precision for acetone was also poor in this batch, with an RPD of 53 percent. O-xylene and trichlorofluoromethane were not detected in any associated samples and no action is taken. No bias to the acetone sample results is indicated.

6-7) TestAmerica provided results from three sets of project specific MS and MSD

analyses (spikes on project samples EPA-MW22C, EA02, and EPA-MW6C) in support of the VOC analyses. Precision and accuracy, as demonstrated by these analyses is acceptable, with the following exceptions. For the project spike of sample EPA-MW22C, several spike recoveries were high, including carbon tetrachloride, chloroform, ethylbenzene, o-xylene, and trichlorofluoromethane. None of these VOCs were detected in the sample spiked, and no bias to the sample results is indicated. MS recoveries for the other project samples spiked were in control.

8) Three surrogates were spiked into each water sample in support of the VOC

analyses. Surrogate recoveries ranged from 109 to 132 percent. Numerous 4-bromofluorobenzene (4-BFB) surrogates were high, exceeding the 114 percent upper project control limit. Several toluene-d8 surrogate recoveries were also high, exceeding the 111 percent upper control limit. One dibromofluoromethane surrogate was high, exceeding 130 percent. A one percent leeway is provided for rounding considerations, as follows:

Many of these detections are already qualified, due to reporting limit (MDL/RL) considerations. Remaining detections are qualified due to the high surrogates.

9) Sample DUP001-11202012 was submitted as a blind field duplicate of primary

sample EPA-MW16A. TCE was detected in the primary and duplicate samples at concentrations of 130 ug/L, each. Precision between the duplicate TCE results is acceptable, with an RPD of 0 percent. Chloroform was detected in the primary and duplicate samples at estimated concentrations. Chloroform is qualified due to

COMMENTS: Performance was acceptable, with the following exceptions and/or notes. 1) The water samples were received chilled at an acceptable temperature of 0.9

degrees Celsius on wet ice. The groundwater samples were properly preserved with hydrochloric acid at the time of collection on November 27, 2012. The samples were analyzed by December 3, 2012, within the prescribed 14-day holding time for preserved VOCs in groundwater.

2) No sample dilutions were required to quantitate any VOCs. All reporting limits are

acceptable, with the following considerations. Some VOCs were reported at concentrations between the method detection limit (MDL) and the reporting limit. Due to limited accuracy in this portion of the calibration range, these VOC results are qualified as J/Estimated. The following results are qualified (pending the results of the blank evaluation).

groundwater sample analyses. No VOCs were detected in any of the method blanks.

Results from one trip blank were provided. Chloroform was detected in the trip blank at an estimated concentration of 0.95 ug/L. Results from two equipment blanks were provided. Chloroform was detected in equipment blank EB001 at a concentration of 1.2 ug/L. Chloroform was detected in equipment blank EB002 at an estimated concentration of 0.74 ug/L. Acetone was also detected in equipment blank EB002 at an estimated concentration of 5.4 ug/L. Acetone was not detected in any of the associated samples, and no action is required. Chloroform was detected in several samples at concentrations within 5 times those of the trip blank and the equipment blanks. Due to potential blank contamination bias, the following chloroform results are qualified as U/non-detect at the concentration reported.

4-5) TestAmerica provided results from three full sets of laboratory control sample (LCS)

and LCS duplicate (LCSD) analyses in support of the groundwater sample analyses. Precision and accuracy, as demonstrated by these analyses is acceptable, with the following exceptions. The LCSD recoveries for carbon tetrachloride and trichlorofluoromethane were high at 129 and 126 percent, respectively, (upper control limits of 123 percent, each) in batch 12L0017. Carbon tetrachloride and trichlorofluoromethane were not detected in the associated samples, and no action is required. The trichlorofluoromethane LCS recovery was high at 129 percent in batch 12L0036. The acetone recovery was high at 155 percent (upper control limit of 153 percent) in the same batch. Precision was also poor for acetone. This batch is associated with the analysis of equipment blank EB002 only, and no action is taken.

6-7) TestAmerica provided results from one set of project specific MS and MSD analyses (spike on project sample EPA-MW14C), and from two sets of batch specific MS and MSD analyses in support of the VOC analyses. Precision and accuracy, as demonstrated by these analyses is acceptable.

8) Three surrogates were spiked into each water sample in support of the VOC analyses.

Surrogate recoveries ranged from 110 to 128 percent. Numerous 4-bromofluorobenzene (4-BFB) surrogates were high, exceeding the 114 percent upper project control limit. Several toluene-d8 surrogate recoveries were also high, exceeding the 111 percent upper control limit, as follows:

Many of these detections are already qualified, due to reporting limit (MDL/RL) considerations and blank contamination for chloroform. Remaining detections are qualified due to the high surrogates. The U/Non-detect qualifier for chloroform supersedes any qualifiers for surrogate recoveries.

9) Field duplicate samples were not submitted with the samples under this chain-of-

custody .

10) No anomalies were noted with respect to results quantitation or reporting.

4-5) TestAmerica provided results from three full sets of laboratory control sample (LCS)

and LCS duplicate (LCSD) analyses in support of the groundwater sample analyses. Precision and accuracy, as demonstrated by these analyses is acceptable, with the following exceptions. An o-xylene LCS recovery was high in one spike. O-Xylene was not detected in the associated samples, and no action is required. Carbon tetrachloride LCS recoveries were high in one spike set. Carbon tetrachloride was not detected in the associated samples, and no action is required. Acetone and 2-butanone LCS recoveries were high in the same spike. Precision was also poor for these two VOCs. Acetone and 2-butanone were not detected in the associated samples, and not action is taken. A 1,2-dichloropropane LCS recovery was high in one LCS. 1,2-Dichloropropane was not detected in the associated samples, and no action is required.

6-7) TestAmerica provided results from two sets of project specific MS and MSD

analyses (spikes on project samples EPA-MW59A and EPA-MW43A), and from one set of batch specific MS and MSD analyses. Precision and accuracy, as demonstrated by these analyses is acceptable, with the following exceptions. The ethylbenzene spike recoveries were high in one project spike, and in the batch spike. Ethylbenzene was not detected in any associated samples, and no action is required.

8) Three surrogates were spiked into each water sample in support of the VOC

analyses. Surrogate recoveries ranged from 100 to 136 percent. Numerous 4-bromofluorobenzene (4-BFB) surrogates were high, exceeding the 114 percent upper project control limit. Several toluene-d8 surrogate recoveries were also high, exceeding the 111 percent upper control limit. Some dibromofluoromethane (DBFM) surrogate recoveries were high, exceeding the 130 upper control limit, as follows:

COMMENTS: Performance was acceptable, with the following exceptions and/or notes. 1) The water samples were received chilled at an acceptable temperature of 4.4

degrees Celsius on wet ice. The groundwater samples were properly preserved with hydrochloric acid at the time of collection on October 9 and 10, 2012. It was noted that sample EPA-MW48A was not preserved to pH <2. No action is taken, as the sample was analyzed within 6 days after sample collection, and the sample bottle was acidified prior to collection. The samples were analyzed by October 17, 2012, within the prescribed 14-day holding time for preserved VOCs in groundwater.

2) Sample EPA-MW48A was diluted by a factor of 5 times for all VOCs. Samples

EPA-MW3C and DUP001 were diluted by a factor of 20 times for all VOCs. No other sample dilutions were required to quantitate any VOCs. All reporting limits are acceptable with the following considerations. Some VOCs were reported at concentrations between the method detection limit (MDL) and the reporting limit. Due to limited accuracy in this portion of the calibration range, these VOC results are qualified as J/Estimated. The following results are qualified (pending the results of the blank evaluation).

Acetone was detected in sample EPA-MW15C at a concentration less than

those detected in the equipment blanks. Due to potential blank contamination bias, this acetone result is qualified as U/non-detect at the concentration reported.

4-5) Accutest provided results from four full sets of laboratory control sample (LCS) and

LCS duplicate (LCSD) analyses (identified as blank spike analyses) in support of the ground. Precision and accuracy, as demonstrated by these analyses is acceptable. All LCS analyses were well within prescribed control limits (60 to 130 percent). Precision between LCS and LCSD recoveries was within prescribed control limits.

6-7) Accutest provided results from one full set of project specific MS and MSD analyses

(spike on project sample EPA-MW15C), and from three sets of batch specific MS and MSD analyses. Precision and accuracy, as demonstrated by these analyses, are acceptable.

8) Three surrogates were spiked into each groundwater sample in support of the VOC

analyses. Surrogate recoveries were acceptable, ranging from 90 to 101 percent. 9) Sample DUP001 was submitted as a blind field duplicate of primary sample EPA-

MW3C. TCE was detected in the primary and duplicate samples at concentrations of 849 ug/L and 843 ug/L, respectively. Precision between the TCE detections is acceptable, with an RPD of 0.7 percent between duplicate sample results.

10) No anomalies were noted with respect to results quantitation or reporting.

The vinyl chloride LCS was slightly low at 80 percent in batch 12J1059. This

batch is not associated with any vinyl chloride analyses, and no action is taken. 6-7) TestAmerica provided results from two sets of project specific MS and MSD

analyses (spikes on project samples EPA-MW9C and MW12), and from two sets of batch specific MS and MSD analyses in support of the VOC analyses. Precision and accuracy, as demonstrated by these analyses is acceptable for all VOCs, with the following exceptions. MS/MSD recoveries for acetone, ethylbenzene, and toluene were high in one of the batch spikes. No action is taken for these VOCs, as acceptable precision and accuracy for these VOCs is demonstrated by the results of the LCS and LCSD analyses.

8) Three surrogates were spiked into each groundwater sample in support of the VOC

analyses. Surrogate recoveries were acceptable, ranging from 98 to 119 percent, with one exception. The 118 percent 4-bromofluorobenzene surrogate recovery for the 10 times dilution of TCE in sample MW12 is high (upper control limit of 114 percent). Due to potential high bias associated with the high surrogate recovery, the TCE result for sample MW12 is qualified as J/Estimated.

9) Two sets of field duplicate samples were submitted with the sample under this

chain-of-custody. Sample DUP001-10222012 was submitted as a blind field duplicate of primary sample EPA-MW10A. TCE was detected in the primary and duplicate samples at concentrations of 120 ug/L and 130 ug/l, respectively. Precision between the duplicate TCE detections is acceptable, with an RPD of 8.0 percent. PCE was detected in both samples of the field duplicate pair at concentrations of 1.2 ug/L, each. Chloroform was detected in both samples of the field duplicate pair at estimated concentrations between the MDL and RL. PCE and chloroform precision are acceptable for the duplicate pair.

Sample DUP001-10223012 was submitted as a blind field duplicate of primary sample EPA-MW42A. TCE was detected in the primary and duplicate samples at concentrations of 31 ug/L and 33 ug/l, respectively. Precision between the duplicate TCE detections is acceptable, with an RPD of 6.3 percent. Chloroform was detected in both samples of the field duplicate pair at estimated concentrations between the MDL and RL. Chloroform precision is acceptable, as duplicate results agree within a reporting limit increment.

10) No anomalies were noted with respect to results quantitation or reporting.

4-5) TestAmerica provided results two full sets of laboratory control sample (LCS) and

LCS duplicate (LCSD) analyses in support of the groundwater VOC analyses. Precision and accuracy, as demonstrated by these analyses is acceptable, with the following exceptions. For batch 12I0394, the LCS recoveries for trichlorofluoromethane were high at 130 and 131 percent (upper limit of 123 percent). No action is required, as trichlorofluoromethane was not detected in any associated samples. For the same batch, LCS and LCS duplicate recoveries for 1,2-dichloropropane were low at 79 percent and 83 percent, respectively (lower control limit of 85 percent). This batch is associated with samples EA05-EFF, EA05-MID, and EA05-INF. Based on the low LCS recoveries, the 1,2-dichloropropane results for these samples may be biased low, and are qualified as UJ/Estimated and non-detect at the reporting limits stated. Precision for acetone is poor in the LCS/LCSD pair, with a RPD of 52 percent. No action is taken, as all acetone data are qualified due to blank contamination, and the acetone LCS results agree within a reporting limit increment.

6-7) TestAmerica provided results from one set of project specific MS and MSD analyses

(spikes on sample 33A-EFF), and from one set of batch specific MS and MSD analyses. Precision and accuracy, as demonstrated by these analyses are acceptable, with the following exceptions. MS and/or MSD recoveries were high for trichlorofluoromethane and TCE in the batch spike. Trichlorofluoromethane was not detected in any associated samples, and no action is required. Precision and accuracy for TCE are demonstrated by the results of the LCS and LCSD analyses, and no action is required.

8) Three surrogates were spiked into each groundwater sample in support of the VOC

analyses. Surrogate recoveries were acceptable, ranging from 92 to 110 percent. 9) Field duplicate samples were not submitted with the samples under this chain-of-

custody. 10) No anomalies were noted with respect to results quantitation or reporting.

exceptions. MSD recoveries in the project spike were high for cis-1,2-DCE, TCE, and trichlorofluoromethane. No action is required, as the associated LCS recoveries for these VOCs demonstrated acceptable accuracy.

8) Three surrogates were spiked into each groundwater sample in support of the VOC

analyses. Surrogate recoveries ranged from 102 to 129 percent, and were within prescribed control limits, with the following exceptions. The toluene-d8 surrogate was slightly high in the following samples (upper control limit of 111 percent):

Sample ID High Toluene-D8 Surrogate

GCLake 112 % MW15 112 % EPA-MW62A 113 % DUP002 113 % EPA-MW23A 112 %

No action is taken, for the slightly high surrogate recoveries at 112 percent, given a 1 percent allowance for rounding issues. VOCs detections in undiluted analyses for samples EPA-MW26A and it duplicate DUP002 are qualified as J/Estimated due to potential high bias. No additional data are qualified as all detections are either between the MDL and RL, or a qualified due to blank contamination.

9) Two sets of field duplicate samples were collected in support of the VOC analyses.

Sample DUP001 was submitted as a field duplicate of primary sample MW16. TCE was detected in the primary and duplicate samples at concentrations of 15 ug/L, each. Precision between TCE results is acceptable, with an RPD of 0 percent. Chloroform was detected in both samples at estimated concentrations between the MDL and RL. Chloroform is qualified due to equipment blank contamination, and is not further assessed in the precision evaluation.

Sample DUP002 was submitted as a field duplicate of primary sample EPA-MW62A. Precision between the duplicate sample results, measured as the relative percent difference (RPD) between the primary and duplicate sample results, is calculated in the following table. Results are presented in micrograms per liter (ug/L).

Sample ID 1,1-DCE Acetone Chloroform PCE TCE

Subject:

Phoenix Goodyear Airport North – Quality Control Evaluation – Fourth Quarter 2012 Groundwater Sampling

The purpose of this memorandum is to provide a summary evaluation of data quality associated with groundwater, waste water, and performance evaluation samples collected during the Fourth Quarter 2012 (includes samples collected in September, October, and November 2012) at the Phoenix-Goodyear Airport-North Superfund Site (PGAN). The review was conducted by a third party Data Validator, Mr. William Huskie, of Nankoweep Environmental Consulting. The review process included evaluation of both field and laboratory quality assurance and quality control (QA/QC) sample results reported. Evaluation criteria for the QA/QC review were based on a combination of SW-846 method requirements, EPA data validation guidance, the Quality Assurance Project Plan (QAPP) prepared for the project, and professional judgment of the third party Data Validator. Groundwater and waste water samples were submitted to TestAmerica Laboratory, located in Phoenix, AZ, for analysis of volatile organic compounds (VOCs) and perchlorate. Two additional laboratories analyzed PGAN samples during the fourth quarter 2012. One data package from each the September, October, and November 2012 sampling events was submitted to ESC laboratory (ESC) located in Mt. Juliet, Tennessee for analysis of VOCs and perchlorate. Similarly, one data package from each month in the fourth quarter was submitted to Accutest Laboratory, located in San Jose, California for analysis of VOCs and perchlorate. Additionally, all three laboratories performed analyses of blind Performance Evaluation (PE) samples (identified as field groundwater samples MW030 and MW031) during the fourth quarter 2012 (November sampling event). A project specific short list of 19 target VOCs was reported from the Method 8260B analyte list for all samples where VOC analysis was requested. Results of the fourth quarter 2012 groundwater sampling (including PE samples) were provided in 29 TestAmerica reports, four ESC reports, and four Accutest laboratory reports (referred to as sample delivery group (SDG) reports).

Individual data validation reports were prepared by the Data Validator for each of the 37 SDGs to assess field and laboratory quality control for the fourth quarter 2012 groundwater sampling events. Standard laboratory quality control deliverables (i.e. Level 3 deliverables) were evaluated for each of the SDGs, as detailed herein. The validation reports were transmitted to Matrix New World Engineering for review and incorporation of data qualifiers into the project database. Validation procedures were used to evaluate the data in terms of accuracy, precision, sensitivity, and completeness. A summary of the validation effort and findings for the fourth quarter 2012 samples is presented in the following sections.

SAMPLE HOLDING TIME EVALUATION Sample holding time limits stipulate the time allowed between sample collection, sample preparation (if required), and sample analysis, when the specified sample preservation and storage procedures are followed (SW-846). The time interval from sample collection to sample analysis, for each sample and parameter tested, was evaluated to determine if the required holding times were met. Sample preservation, chain-of-custody documentation, and sample receipt documentation were also reviewed. All samples submitted for analysis of VOCs during the fourth quarter 2012 sampling events were properly preserved with hydrochloric acid, and were analyzed within prescribed holding time of 14 days. All samples submitted for analysis of perchlorate were analyzed within the required 28-day holding time. All samples were placed on wet ice in coolers at the time of sample collection. Samples were hand delivered to TestAmerica laboratory, usually on the day of sampling, or on the following day. Samples submitted to ESC and Accutest laboratories were shipped under proper chain-of-custody procedures. Samples should arrive at the laboratory chilled to a temperature of 4.0 degrees Celsius (+/- 2 degrees Celsius). No temperature exceedances were recorded. Some samples have been received at temperatures less than 2 degrees Celsius. No action was required, as no samples arrived at the laboratory frozen.

QUALITY ASSURANCE – FIELD SAMPLES Twenty-nine trip blanks and 44 equipment rinsate blanks were submitted from the field to the laboratories to evaluate potential contamination from sampling operations, field conditions, sample handling, decontamination procedures, and sample transport. Twenty-eight sets of blind field duplicate samples were submitted to monitor field and laboratory quality control with respect to analytical precision during the fourth quarter 2012 sampling event. Results of the field quality control sampling are discussed in detail in the following sections. FIELD DUPLICATES Twenty-eight sets of field duplicate samples were collected during the fourth quarter 2012 groundwater sampling events. Precision between the major constituents of concern for the groundwater monitoring program (trichloroethene (TCE) and perchlorate) was very good, with all RPDs less than the QAPP specified RPD precision control limit of 25 percent, with the following exceptions. TCE precision was poor between the following field duplicate samples analyzed by Accutest in one November 2012 SDG.

SDG Sample(s) Affected C23118 EPA-MW3C and DUP001 Due to the poor precision, TCE results for these samples were qualified as J/Estimated. Perchlorate precision was poor between the following field duplicate samples analyzed by ESC in one November 2012 SDG. SDG Sample(s) Affected L605508 PZ01 and DUP001 Due to the poor precision, perchlorate results for these samples were qualified as J/Estimated. Precision for all remaining target analytes for the investigation was acceptable, with RPDs less than the project specified control limit of 25 percent between field duplicate results, or with duplicate results in agreement within a reporting limit increment. LABORATORY DUPLICATES TestAmerica and ESC provided results from batch specific and project specific laboratory duplicate analyses in support of the perchlorate results for each analytical batch. Laboratory duplicate precision for the perchlorate analyses was within laboratory-prescribed RPD control limits for each of the duplicate analyses, or was in agreement within the 2 ug/L reporting limit increment. TRIP BLANK ANALYSES A trip blank is defined as a sample of analyte-free water prepared at the laboratory, shipped to the sampling site, and returned to the laboratory unopened for analysis. The objective of a trip blank sample is to document potential contamination associated with sample shipping procedures, field and laboratory handling procedures, or other contamination associated with organic-free and deionized water provided by, and used within the laboratory. Trip blank samples are particularly useful in documenting VOC contamination from outside sources. Thirty-nine trip blanks were submitted to TestAmerica/ESC/Accutest laboratories in support of the fourth quarter 2012 VOC analyses. VOCs were not detected in the trip blanks, with the exceptions described below: Acetone, methylene chloride, and chloroform were detected in some trip blanks during the fourth quarter 2012 sampling events. In some cases, acetone was detected in trip blanks, but was not detected in the associated samples, and no action was required, as no bias to the sample results was indicated. In other cases, acetone, methylene chloride, or chloroform were detected in the associated groundwater samples at concentrations similar to the concentrations reported in the trip blanks, as described below. Acetone was detected in trip blanks from one September TestAmerica SDG, and from one October ESC SDG at concentrations within ten times those of associated groundwater samples (ten times rule for common laboratory contaminants – though actual sample concentrations were generally within a factor of two to three times the blank detections). The following acetone sample results were qualified as “U/non-detect at the concentrations reported” due to potential blank contamination bias.

DECONTAMINATION WATER BLANK ANALYSES Decontamination water blanks were not collected during the fourth quarter 2012 sampling event.

LABORATORY QUALITY ASSURANCE/QUALITY CONTROL DATA The laboratory QA/QC program included evaluation of results from method blanks, matrix spike samples, laboratory control samples, and surrogate spike samples. Inorganic and organic quality control sample results were evaluated using project specified control limits, guidelines specified in SW-846, and applicable laboratory prescribed control limits.

METHOD BLANK ANALYSES Method blanks are prepared from analyte-free water to which all reagents are added in the same volumes and proportions as used in the sample processing. The objective of method blank analysis is to determine the existence and magnitude of potential contamination associated with laboratory methodologies for analysis of inorganic and organic parameters. Target analytes should not be detected in method blanks at concentrations above standard laboratory reporting limits. Method blank analyses were performed by TestAmerica, ESC, and Accutest laboratories in support of each analytical method performed for each sample batch analyzed. Perchlorate was not detected in any method blanks. Some target VOCs were detected in the method blanks at estimated concentrations (between the MDL and RL). These included acetone, methylene chloride, and chloroform. Acetone was the only one of these VOCs that was detected

in associated samples, resulting in data qualifications. Acetone was also detected in the associated equipment blanks. Data qualified for acetone blank detections are summarized in the equipment blank section descried in the preceding pages.

LABORATORY CONTROL SAMPLE EVALUATION A laboratory control sample (LCS) is a known matrix spiked with compounds representative of the target analytes. Laboratory control samples are used for assessing the accuracy of a method (including any preparation steps) in a controlled matrix for inorganic and organic parameters. A laboratory control sample meeting recovery criteria provides evidence that the method, exclusive of sample matrix considerations, is in control. Laboratory control sample duplicate (LCSD) analyses may also be performed to demonstrate method precision in a controlled matrix. TestAmerica, Accutest, and ESC laboratories provided LCS and/or LCS/LCSD results for each method performed for each sample batch analyzed. All of the target VOCs for the Method 8260 analyses were included in the LCS spikes for each batch. For the fourth quarter 2012 VOC analyses, some LCS and/or LCSD analyses had target compound recoveries that were outside control limits, and biased high. The magnitude of the LCS excursions was generally small, typically within 5 percent of the stated control limits. VOCs with high LCS recoveries included benzene, toluene, ethylbenzene, xylenes, trichlorofluoromethane, carbon tetrachloride, and 1,1,2,2-tetrachloroethane. No validation action was required for VOCs with high LCS recoveries, unless that VOC was detected in the associated samples, indicating potential high bias. Acetone was the only VOC qualified in the fourth quarter due to high LCS recoveries. Acetone data were qualified as J/Estimated for the following PE samples in one November 2012 SDG from TestAmerica due to high LCS recoveries, as follows. SDG Sample(s) Affected PVK1726 MW030 and MW031 Some fourth quarter LCS and/or LCSD analyses had target compound recoveries that were outside control limits, and biased low. These included methylene chloride, 1,2-dichloropropane, PCE, and vinyl chloride. A low LCS recovery typically impacts all samples of the associated batch, as results for both detections and non-detects are qualified due to potential low bias. Several SDGs had sample results qualified due to low LCS recoveries, as follows: Methylene chloride data were qualified as “UJ/Estimated and non-detect at the reporting limits stated” for the following samples in one September 2012 SDG due to low LCS recoveries SDG Sample(s) Affected PVI0290 COG03, EPA-MW10A, EPA-MW10C, and EPA-MW9C 1,2-Dichloropropane data were qualified as “UJ/Estimated and non-detect at the reporting limits stated” for the following samples in one September 2012 SDG due to low LCS recoveries, as follows.

Methylene chloride data were qualified as “UJ/Estimated and non-detect at the reporting limits stated” for the following samples in one October 2012 SDG due to low LCS recoveries, as follows. SDG Sample(s) Affected PVJ0682 33A-102, 33A-201, 33A-EFF, 33A, EA-05-EFF, EA-05, EA-05-MID, EA-06-EFF, EA-06-INF, EA-06-MID, EA-08-EFF, EA-08, EA-08-MID, PH1-EFF, PH1-INF, PH23-EFF, and PH23-INF Vinyl chloride data were qualified as “UJ/Estimated and non-detect at the reporting limits stated” for the following samples in three October 2012 SDGs due to low LCS recoveries, as follows. SDG Sample(s) Affected PVJ1577 EPA-MW30A, EPA-MW50A, EPA-MW42A, DUP001, and MW12 SDG Sample(s) Affected PVJ1575 IR27C-170 and IR27C-258 SDG Sample(s) Affected PVJ1475 EPA-MW39C, EPA-MW39A, EPA-MW45A, EPA-MW54A, EPA-MW35A,

IR3B, EA07, EPA-MW59A, EPA-MW61A, IR34B, DUP001, GCLake, MW25, and EPA-MW38A

PCE data were qualified as “UJ/Estimated and non-detect at the reporting limits stated” for the following samples in one November 2012 SDG due to low LCS recoveries, as follows. SDG Sample(s) Affected PVK1450 LPW894, EPA-MW22C, EPA-MW55A, EPA-MW39C, EPA-MW39A,

EPA-MW45A, EPA-MW16C, and EPA-MW35A

Precision between LCS and LCSD recoveries was poor for acetone and 2-butanone in a several SDGs. Acetone and 2-butanone were not detected in the associated samples. The magnitude of the poor precision was often small (based on an RPD precision control limit of 25 percent), and no bias to the associated sample results was indicated. The contract laboratories flagged all analytical results with associated LCS excursions on the analytical results pages. The flags noted the possible bias direction, as required by the Arizona Department of Environmental Quality. Acetone LCS results were flagged “E4” for some reports because the spike result was less than the 20 ug/L reporting limit for acetone, with the amount spiked of 25 ug/L. Acetone LCS recoveries, calculated using the “estimated” result below the 20 ug/L reporting limit were within control limits, and no bias to the sample results was indicated. For the fourth quarter 2012 perchlorate analyses, precision and accuracy, as demonstrated by the LCS and LCSD analyses were determined to be acceptable.

MATRIX SPIKE ANALYSES A matrix spike (MS) is defined as an aliquot of sample spiked with a known concentration of selected target analytes. MS duplicates (MSD) are intra-laboratory split samples spiked with identical concentrations of target analytes. The spiking occurs prior to sample preparation and analysis. The purpose of the MS and MSD analyses is to assess the effect of the sample matrices on laboratory accuracy and precision for inorganic and organic parameters. Organic analysis MS recoveries are considered advisory, and no validation action was performed for the fourth quarter groundwater 2012 investigation based solely on the results of MS recoveries reported outside of QC limits. Poor spike recoveries do not necessarily represent an error in the analytical system. It is possible that unavoidable interferences from the sample spiked preclude efficient recoveries. Other samples spike in the same batch, may not have the same matrix characteristics. Therefore, the organic MS/MSD data were used in conjunction with other quality control data (specifically LCS/LCSD results) to determine the overall quality and usability of the data. Matrix New World designated several project specific samples for MS and MSD analysis during the course of the fourth quarter 2012 groundwater investigation. In many cases, results from batch specific MS and MSD analyses were also provided in the same SDGs. Precision and accuracy, as demonstrated by MS/MSD data reported in support of the fourth quarter 2012 VOC analyses were acceptable, with some exceptions. MS and/or MSD recoveries were out of control and biased high for the following VOCs in one or more SDGs: Cis-1,2-DCE, trichlorofluoromethane, TCE, acetone, ethylbenzene, toluene, 1,1,2,2-tetrachloroethane, carbon tetrachloride, and chloroform. In the few cases where these VOCs were detected in the associated samples, the detections were often at concentrations between the MDL and RL, and the data were already qualified. Acceptable precision and accuracy for these VOCs was also demonstrated by the results of the LCS and LCSD analyses. MS and/or MSD recoveries were out of control and biased low for the following VOCs in one or more SDGs: Methylene chloride, m/p-xylenes, and ethylbenzene. The magnitude of the low recoveries was generally small, within 5 of the lower laboratory recovery control limit. In cases with low MS and MSD recoveries, the associated LCS and LCSD recoveries typically demonstrated acceptable precision and accuracy, and the VOC data were not qualified (one exception was for methylene chloride, where the associated LCS recoveries were also low and the methylene chloride results were qualified). For one SDG, TCE spike recoveries were out of control, where the TCE concentration in the sample spiked was more than four times greater than the spike added amount. No action was taken in these cases, as the representativeness of the spike recovery is diminished in this scenario. MS and MSD recoveries for perchlorate were within prescribed control limits of 75 to 125 percent for all fourth quarter 2012 analyses.

SURROGATE SPIKE ANALYSIS A surrogate is an organic compound which is similar to method target analytes in chemical composition and behavior in the analytical process, but which is not normally found in groundwater samples. For all VOC analyses and dilution analyses, each field sample, QC sample, and blank was

spiked with three surrogate compounds prior to purging or extraction. Surrogate recoveries were calculated to evaluate the ability of the analytical procedures to recover the true amount of a known compound in the sample matrix. Surrogate recoveries were reported in support of all VOC analyses performed for the fourth quarter 2012 groundwater monitoring event. Surrogate recoveries were within laboratory-prescribed control limits, with the following exceptions. Surrogate recoveries for three samples in two ESC SDGs were low for samples where no VOCs were detected. VOC results for these samples were qualified as “UJ/Estimated and non-detect at the reporting limits stated” due to potential low bias, as follows: SDG Sample(s) Affected L596529 (ESC) DUP001-09182012 and EPA-MW13A (all VOCs = UJ) SDG Sample(s) Affected L600820 (ESC) EPA-MW12C (all VOCs = UJ) During late October 2012, and during all of November 2012, TestAmerica reported high surrogates for nearly all samples in nearly all SDGs. Many 4-bromofluorobenzene (4-BFB) surrogates were high, exceeding the 114 percent upper project control limit. Many toluene-d8 surrogate recoveries were also high, exceeding the 111 percent upper control limit. One dibromofluoromethane surrogate was high, exceeding 130 percent. VOCs detected in these samples were qualified as J/Estimated due to potential high bias. In nearly all of these cases, the surrogates in question were well within current statistically-derived TestAmerica laboratory control limits. Therefore, the laboratory did not perform any corrective actions for these SDGs, based on the exceedences of the project control limits. It is noted, that during December 2012, TestAmerica regained control of these surrogates to levels again meeting project control limits. Therefore, these potential high biases are generally limited to the November 2012 timeframe. The following SDGs and samples had qualified VOC results due to high surrogates.

RESULTS QUANTITATION Sample results were evaluated to determine if sample dilutions were appropriate, and to evaluate sample reporting limits in terms of sensitivity DQOs. For the VOC analyses, several dilutions were required to bring target VOCs into linear range for quantitation. In general, only the VOCs exceeding the undiluted calibration range (200 ug/L for most VOCs) were reported from dilutions. The sensitivity DQO for the VOC analyses was satisfied, with the following considerations.

Beginning with the second quarter 2007 sampling event, the contract laboratory was required to report all VOC detections quantified between the MDL and the RL. Reporting to the MDL was performed for a selected set of 19 target VOCs. These VOCs were noted with an “E8” flag in the TestAmerica reports. Any detections between the MDL and standard RL were flagged with an “E4” qualifier by TestAmerica or a “J” qualifier by ESC and Accutest Laboratories. Several VOCs were reported as detections in this range, and all of these were qualified as J/Estimated due to potential limited accuracy in this portion of the calibration range (some of the VOCs detected in this range were then superceded by the “U/non-detect” qualifier in SDGs, where blank contamination was also associated with the sample detections). Chloroform (93 samples), TCE (23 samples), PCE (23 samples), 1,1-DCE (16 samples), acetone (6 samples), and carbon tetrachloride (4 samples) were the most common VOCs detected at concentrations between the MDL and RL. Other VOCs detected one or more times between the MDL and RL included cis-1,2-DCE, toluene, and 2-butanone. For many of the fourth quarter 2012 laboratory reports, perchlorate detections were reported at concentrations less than the standard 2 ug/L TestAmerica reporting limit (which is also the project sensitivity goal of 2 ug/L), but at concentrations greater than the MDL. TestAmerica laboratory noted each case and flagged the perchlorate results with an “E4”. Due to limited accuracy in this portion of the calibration curve, 14 perchlorate sample results were qualified as J/Estimated. ESC laboratory performed nearly all perchlorate analyses at dilutions, due to stated matrix interferences. In most of these samples, no perchlorate was detected. A five times dilution from ESC results in a reporting limit of 2.5 ug/L for perchlorate (compared to the 2.0 ug/L TestAmerica reporting limit with no dilution).

DATA QUALIFICATION DISCUSSION During the fourth quarter 2012, many VOC data were qualified as a result of high surrogate recoveries reported during November 2012. The laboratory did not perform corrective action for the surrogate excursions, as the recoveries were well within laboratory derived control limits. The high recoveries exceeded project specific control limits for surrogates toluene-d8 (upper control limit of 111 percent) and 4-bromofluorobenzene (upper control limit of 114 percent). By comparison, only one sample exceeded the dibromofluoromethane surrogate project control limit of 130 percent. Results for samples reviewed from December 2012, indicated that TestAmerica was again in control, with respect to project specified surrogate control limits for all three surrogates. TestAmerica continues to note that some MDLs have changed relative to project requirements, due to updates from ongoing MDL studies. A large portion of the VOC detections for PGAN groundwater samples are at concentrations between the MDL and the standard laboratory reporting limits. If current study-derived laboratory MDLs are higher then the required project MDLs, then some of the VOC detections reported as “J” or “E4” values may be more statistically valid as non-detects. The blank evaluation is nominally based on “factors of safety” such that VOC detections in groundwater samples within five times those in associated blanks (or ten times for common laboratory contaminants acetone and methylene chloride), are qualified as “U/non-detect at the concentration reported.” Such factors of safety prevent false positive data points from being incorporated into the site evaluation. In practice, for the PGAN project, these five and ten times

Page 314: PGA NORTH – GROUNDWATER SAMPLING VALIDATION OF …DUP001-09142012 EB001-09142012 The calibration was a 9-point calibration analyzed at the following concentrations (0.5, 1.0 2.0,

13/15

outer limits for data evaluation against blank contamination were rarely tested. It was far more common that blank detections were at concentrations within a factor of 2 to 3 times those of the associated qualified groundwater sample results. In some cases, blank detections were reported at concentrations higher than those of the samples in question. Many VOCs results qualified due to associated blank contamination, already had initially lower data quality, as they were reported at concentrations between the MDL an RL of the analysis. LEVEL 4 DATA EVALUATION Results from eight level 4 (full quality control deliverables) data packages were evaluated for SDGs from September, October, and November 2012. One level 4 SDG from November 2012 will be re-submitted in the 1st Quarter 2013, due to missing data in the initial delivery.

The level 4 data packages were evaluated for each of the Level 3 QC elements described above, with the addition of the following:

Gas chromatography/Mass spectroscopy instrument tuning (VOCs) Initial calibration and initial calibration verification Continuing calibration verification Internal standards, area and retention times (VOCs) Chromatogram review Raw data review GCMS instrument use Standards Preparation

VOCs – GC/MS tunes were reported in the raw data at frequencies such that all water sample analyses and QC sample analyses were bracketed by successful tunes every 12 hours. Results from nine-point initial calibrations were provided in support of all VOC analyses. For the data packages reviewed, one or two initial calibrations were associated with the samples in each SDG. Up to four continuing calibrations were provided with each initial calibration. Initial calibrations and sample analyses were performed by TestAmerica on GC/MS instruments #2, #4, #7, and #9. No bias was noted based on comparison of sample results and quality control results between the different instruments used on the PGAN project. Response factors and percent relative standard deviations (%RSD) were evaluated for each calibration. Based on the level 4 data review, groundwater sample results for 2-butanone were qualified in the approximately half of the data sets reviewed due to low response factors. The initial calibration response factors for 2-butanone were less than the minimum criteria of 0.05 used for all other project target VOCs. Continuing calibration response factors for 2-butanone were also low for the SDGs where the initial calibration response was low. 2-Butanone was not detected in the associated groundwater samples, and 2-butanone results for these SDGs were qualified as R/Rejected. 2-Butanone in known to be a poor performing calibration constituent due to low purge efficiency. As such, a lower response factor of 0.01 is allowed by the method for 2-butanone (and other poor performers) in the initial and continuing calibrations so that the calibrations can pass. However, for data validation purposes, the 2-butanone results are evaluated against the same calibration criteria as those for the other target VOCs, so that the data quality comparison is equivalent.

For VOCs with %RSDs greater than 15 percent, linear or quadratic calibrations were performed. Associated linear correlation coefficients were determined to be acceptable with correlation coefficients greater than 0.995. Quadratic curves for acetone and 2-butanone were evaluated against a calibration coefficient of greater than 0.99 The initial calibrations were acceptable for all other short list VOC target compounds. It is noted that two to four of the low level calibration standards for acetone and/or 2-butanone were omitted from the calibration curves in order to improve response factors and RSDs. This resulted in an elevated reporting limit provided for acetone (20 ug/L) in the data packages. Results from initial calibration verifications (ICV - second source standards at concentrations of 25 ug/L and 20 ug/L) were provided with each initial calibration. ICV recoveries were within prescribed control limits for each calibration. Percent deviations between average response in the initial calibration and those in the second source standards were less than 25 percent. Continuing calibrations were evaluated for each day of groundwater sample analysis. Continuing calibration standard recoveries were within specified laboratory control limits for all target VOCs. Percent differences between responses factors in initial and continuing calibrations were less than 25 percent for target VOCs, with the exception of acetone in one SDG. These VOCs were qualified as “UJ/Estimated and non-detect at the reporting limits stated” due to the high percent differences. Response factors for VOCs in continuing calibrations were greater than 0.05, with some exceptions for 2-butanone. In each of these cases, 2-butanone was qualified due to the initial calibration. The raw data for each sample was reviewed. Ion chromatograms and GC/MS specta were checked for VOC target compound detections. Results quantitation was determined to be acceptable, based on these reviews. Final reported concentrations matched the raw data values and sample dilutions were properly accounted for. Perchlorate – All groundwater perchlorate results were quantified based on a 5-point initial calibration. Initial calibrations dated May 29, 2012 and September 26, 2012 were referenced for most perchlorate analyses reported for the fourth quarter 2012. The linearity for each of the initial calibrations was acceptable, and no data were qualified based on calibrations. Correlation coefficients for each 5-point calibration were greater than 0.995. Initial calibration check standards (ICCS), continuing/ending calibrations check standard (CCCS/ECCS), and instrument performance check (IPC) standards, and second source standards were analyzed at various concentrations within each analytical batch (typically 2 ug/L, 25 ug/L, and 40 ug/L). The calibration standard recoveries were evaluated based on 85 to 115 percent recovery criteria. IPC standards were evaluated at 80 to 120 percent. ICCS standards were evaluated based on control limits of 75 to 125 percent. No perchlorate data required qualification based on the results of the continuing calibration analyses. It was noted that in some SDGs, several ICCS had recoveries of greater than 125 percent, and several analyses were required to obtain an acceptable ICCS. All ion chromatograms were reviewed and raw data were checked against the final reported values. Final reported concentrations matched the raw data values. No other data quality issues were identified based on the results of the level 4 validation review.

DATA USABILITY There were no significant data usability issues noted for the fourth quarter 2012 groundwater sampling events, with the following considerations. For samples collected in November 2012, all VOC detections from TestAmerica laboratory were qualified due to elevated surrogate recoveries. Many 4-bromofluorobenzene surrogate recoveries were high, exceeding the 114 percent upper project control limit. Many toluene-d8 surrogate recoveries were also high, exceeding the 111 percent upper control limit. VOCs detected in these samples were qualified as J/Estimated due to potential high bias. In nearly all of these cases, the surrogates in question were well within current statistically-derived TestAmerica laboratory control limits. Therefore, the laboratory did not perform any corrective actions for these SDGs, based on the exceedences of the project control limits. A review of several SDGs from December 2012 indicates that these surrogate recoveries were back in control, relative to project specific control limits.

DATA QUALITY SUMMARY Based on the review of the analytical reports provided by TestAmerica, Accutest, and ESC laboratories, the data reported for the fourth quarter 2012 groundwater sampling events at the PGA North site are determined to be quantitative and usable, with the considerations noted herein and detailed in the SDG-specific validation reports. Completeness objectives for the analyses performed during the fourth quarter 2012 meet the project DQOs for data usability, with the possible exception of that for 2-butanone. 2-Butanone results were qualified as R/Rejected for non-detect concentrations in over half of the level 4 data packages evaluated due to poor responses in the initial calibrations and continuing. Removal of the lowest concentration calibration points (up to four points) for acetone and 2-butanone in the initial calibrations often improved the average response to acceptable levels, though with increased reporting limits.
