APPENDIX F

REMEDIAL INVESTIGATION -SAMPLING AND ANALYTICAL,PROGRAM

F.I GENERAL

The following subsections briefly summarize the sampling and analyticalprogram Implemented during the Bruin Lagoon remedial Investigation.Detailed procedures for sample collection, preservation, shipping,documentation, and decontamination are provided in the Work Plan andPOP. Sampling rationale, health and safety guidelines, and QA/QC arealso discussed in these documents.

It should be noted that the sample containers used during the BruinLagoon remedial investigation were obtained through the CLP's samplebottle repository program. Following collection, samples were preservedas required, packed in coolers in accordance with U.S. Department ofTransportation (DOT) regulations, and shipped via overnight carrier to •the designated CLP laboratory. CLP paperwork (i.e., sample tags,chain-of-custody forms, traffic reports, SAS packing lists) werecompleted as appropriate and included with each sample shipment. Allanalyses performed at the site were completed as soon as possible aftersample collection.

F.2 AIR MONITORING

Air monitoring was conducted throughout the Bruin Lagoon remedialinvestigation primarily for health and safety purposes during drilling.and sampling activities. Air monitoring was also used as a screeningtechnique to characterize the gases present beneath the lagoon surfacethat could be released during drilling operations. The gases of concernwere hydrogen sulfide (H S), sulfur dioxide (SOp), and volatileorganics. Air monitoring activities during drilling consisted of:

• Health and safety monitoring.

• Site perimeter monitoring. •

• Ambient breathing zone monitoring.

• Downhole sampling and analysis.

• Sample screening.

The following air monitoring equipment was available on-site during alldrilling activities:

• HNu photoionization detector (PID) with 11.7 and 10.2 eV probes.

• OVA (organic vapor analyzer) - flame ionization detector (FID).

• H2$ portable gas monitor.

• S02 portable gas monitor.

• H2$ monitor alarms.

• Explosimeter/oxygen monitor.

• Detector tubes - SOj, H2$, H2S04, 02, C02, natural gas.

F-2 1222

Due to the known gases present from past site work, portable directreading real-time instrumentation was primarily utilized for gascharacterization and health and safety purposes. Detector tubes wereused for screening of possible instrumentation interferences,confirmation of direct reading concentrations, and analysis of gases notdetected on available instrumentation.

Monitoring equipment and detector tubes were used in accordance with themanufacturer's operating instructions. Prior to all investigativeactivities, each Instrument was calibrated using specific calibrationgases. Weekly calibrations and daily response checks were made to ensureinstrument operation. Instrumentation that did not respond or calibratecorrectly was not used on field activities.

Table F-l presents the specific air monitoring equipment used with modelnumbers, detectable gases, detection ranges, alarm concentrations,sensitivities, and possible interferences.

The direct reading monitoring instruments determined to be most effectivefor monitoring drilling operations were the HNu PID (11.7 eV), H«Sportable gas monitor, H,,S monitor alarms, and SOp portable gasmonitor. The HNu PID (11.7 eV) was selected over the OVA FID due to thesensitivity of the unit to hydrogen sulfide gas. As a result, the HNuPID (11.7 eV) could detect both hydrogen sulfide gas and organic vapors.This selection was made because of past historical data demonstratingpossible HpS gas release.

Periodic monitoring of ambient air at the site perimeter was performedroutinely during drilling operations. Also, if ambient breathing zoneconcentrations Indicated possible gas releases, perimeter monitoring wasinitiated immediately. Seventeen monitoring locations were establishedalong the site fence line at intervals of approximately 150 feet andmarked with stakes. The perimeter monitoring locations are shown inFigure F-l. Perimeter monitoring was conducted with the HpS and SOpportable gas monitors and the HNu PIO (11.7 eV).

During all drilling operations, the HpS and SOp portable gas monitor,H2S monitor alarms, exploslmeter/oxygen monitors, and HNu PID (11.7 eV)were used for characterization of the ambient breathing zone. Backgroundlevels were determined prior to the start of the drilling work. Portableinstrument readings were utilized to provide continuous, real-timemonitoring of each split spoon and drilling depth to determine at whatdepth, if any, gas releases occurred.

If ambient breathing zone monitoring showed elevated concentrationssignificantly above background levels, a grab sample of the gas presentin the boring/well was collected for analysis. These grab samples wereanalyzed to characterize the emitted gases. Grab samples were collectedfrom a point approximately three feet below the ground surface byinserting tubing into the well/boring and pumping the gas into an air bagcollector. The bag sample was then sealed and analyzed on-site usingavailable instrumentation and detector tubes.

The portable gas monitors were also used during drilling operations forsplit spoon and bedrock core sample screening. Each split spoon and coresample was scanned with all direct reading Instrumentation Immediatelyafter collection. Samples showing positive readings were usuallyselected for chemical analysis.

Air monitoring was also performed as a health and safety measure duringthe two rounds of subsurface gas, groundwater, and surface-water samplingconducted 1n September and October. Portable monitoring instrumentationand detector tubes were utilized to characterize the ambient breathingzone during these on-site activities.

F.3 SEDIMENT

Sampling and analysis of sediments from the two ponds located on theabandoned refinery property along the southern boundary of the BruinLagoon site was conducted to verify that they do not contain significantquantities of waste materials.

Pond sediment sampling was performed on June 19-20, 1985. Samples werecollected from the ponds across three transects distributed along eachpond as shown in Figure F-2. Each sample was a composite composed ofthree grab samples collected from the middle and either side of thetransect.

Samples were collected from a boat using a clamshell dredge. Individualgrab samples across a transect were composited in a stainless steelbucket, mixed thoroughly, and decanted before being placed into samplecontainers. An HNu PID (11.7 eV) was also used to scan the samples. Theclamshell and bucket were decontaminated between samples. In addition tothe six composite samples, duplicate and blank samples were alsocollected.

Pond sediment samples were analyzed for TOC, oil and grease, volatile andsemi-volatile HSL compounds, and EP toxicity (metals only). Allanalytical work was performed using the CLP.

F.4 SOIL

Sampling and analysis of on-site and off-site soils was performed todefine the nature and extent of contamination at Bruin Lagoon and toprovide a stratigraphic record of the site.

Soil sampling was conducted during drilling operations at the site fromlate June through mid-August 1985. Fifty-nine samples were collected forchemical analysis during the construction of borings for shallow wells(AW), bedrock wells (DW), and soil borings (SB). These samples werecollected at discrete 2-foot Intervals with depths ranging from 0 to 26feet. Figure F-3 shows the locations of the wells and borings.

ASOQI229

AROOI230

For each we11/boring constructed, continuous sampling was performed fromthe surface to auger refusal using ASTM-approved split spoon barrels. Adecontaminated split spoon was used for the collection of each sample.

Samples for chemical analysis were selected on the basis of visualappearance and readings obtained from screening with the portable airmonitoring equipment. A portion of each sample was also retained as anarchive record of the 2-foot interval sampled. These stratigraphicsamples are stored on-site in the decontamination trailer. QA/QC sampleswere collected as part of the soil sampling task.

The soil samples were analyzed for the contamination indicator parameters- pH, TOC, and oil and grease. Additionally, approximately 30 percent ofthe samples were analyzed for HSL organic (volatiles and semi-volatiles)and inorganic (metals) compounds and S04. All analyses were performedby the CLP.

F.5 BEDROCK

Sampling and analysis of bedrock was performed to delineate the extent ofcontamination in the bedrock under the Bruin Lagoon site.

Bedrock sampling was conducted during drilling operations at the sitefrom late June through mid-August 1985. Approximately 680 feet ofbedrock was cored during the construction of bedrock wells (DW) and soilborings (SB), and 27 samples were collected for chemical analysis. Thesesamples were collected at depths varying from approximately 13 to 51feet. The well and boring locations from which bedrock samples werecollected are shown in Figure F-4.

F-ll A100I23I

F-12 AROOI232

Bedrock coring was performed using an NQ core barrel in increments offive feet. The bedrock was visually inspected and scanned with thedirect reading air monitoring equipment, and then placed in core boxes.These boxes are stored on-site in the decontamination trailer.

Samples for chemical analysis were selected to provide a vertical profileof the bedrock at a particular boring location. A 6-inch section of thebedrock was typically removed from the core length and pulverized with asledge hammer to yield a sand matrix which could be analyzed.Pulverization of the bedrock samples was performed at the site in earlyAugust 1985. Duplicate and blank samples were also collected andanalyzed under the bedrock sampling program.

All of the bedrock samples were analyzed for the pH, TOC, and oil andgrease indicator parameters. Seven samples were also selected foranalysis of volatile HSL compounds. The CLP performed all the analyticalwork for the bedrock samples.

F.6 SUBSURFACE GASES

Sampling and analysis of gases present under the site was performed toidentify their composition and location, determine the regenerationrates, and assess the potential for their release into the atmosphereduring remedial construction work.

F'13 AROOI233

Two rounds of subsurface gas sampling and analysis were conducted at thesite. The first round was performed in early September 1985,approximately one month after the completion of the well Installationprogram. The second sampling occurred about one month after the firstduring the second week of October 1985. Twenty-three samples werecollected during each of the two Identical sampling rounds.

• •

The sampling program for each round consisted of the collection of a grabsample of the gases contained in the 10 shallow wells (AW) installed aspart of the remedial Investigation and the 13 shallow wells (A) installedby the emergency contractor during the summer of 1984. These welllocations are shown in Figure F-5.

Grab samples of the gases contained at the top of the shallow wells werecollected using the air sample connector located in the cap of the wellhead. The design of the shallow monitor well heads is shown In FigureF-6. Samples were collected using two sections of Teflon tubing, apersonal sampling pump, and an air bag. One length of tubing was •attached to the air sample connector on the well and the inlet of thepump, while the other piece of tubing was connected to the outlet of thepump and the air bag. A sample volume of approximately 10 liters wascollected from each well.

New sections of Teflon tubing were used at each well and the pump waspurged with ambient air between each sample's collection. This procedurewas used to prevent possible cross-contamination between wells.Duplicate and background samples were also collected for QA/QC purposes.

The gas samples were analyzed immediately after collection by on-siteWESTON personnel. Each sample was analyzed for volatile organics, SOp,H2S, H2S04, 02, C02, and natural gas. An HNu PID with 11.7 eVprobe was used to measure the volatile organics content of the samples.Analysis of the six other constituents was made using Draeger detectortubes. Samples were drawn directly from the air bags for analysis via a3-inch length of tubing. Analytical determinations were performedfollowing the manufacturer's operating instructions.

F.7 SURFACE WATER AND 6ROUNDWATER

Sampling and analysis of surface water and groundwater was performed todetermine the impact of the Bruin Lagoon site on the South Branch of BearCreek, and to define the extent of contamination in the shallow liquidzone and the bedrock aquifer. Elevations of the shallow liquid zone andthe bedrock aquifer, and the South Branch of Bear Creek were alsomeasured to develop groundwater contour maps.

Two identical rounds of water sampling and analysis were conducted at thesite. This work was performed immediately after subsurface gas samplingand analysis was completed. As a result, surface water and groundwatersampling occurred in mid-September and mid-October 1985, approximatelyone and two months after the installation of the monitor wells.

The sampling program for each round consisted of the collection of twograb samples from the South Branch of Bear Creek and one sample from eachof the 23 shallow wells (AW and A), 10 bedrock wells (DW), and oneresidential bedrock well (Hawk). It should be noted that some of theshallow wells were dry and, consequently, samples could not be obtained.

F-17 W800.I237

The surface-water sampling stations were located approximately 50 feetupstream and downstream of the site fence line. The locations of thesestations and the monitor wells are shown in Figure F-7 and F-8,respectively.

Prior to sampling, depth to water/oil measurements were made In each wellusing a water-level Indicator probe. 011 was present in a number of theshallow wells. The probe was decontaminated between wells. Surface-water elevations were also determined at three staff gauges along theSouth Branch of Bear Creek adjacent to the site. The locations of thestaff gauges are also Indicated in Figure F-7. All of the water surfacemeasurements were made 1n a single day to develop elevation contourplots. Water measurements were determined on September 6, 1985 andOctober 10, 1985 for the first and second rounds of sampling,respectively.

Surface water sampling was performed by wading to the middle of thestream and directly filling the sample containers with water. The •downstream location was sampled first. Approximately 20 minutes elapsedbetween the collection of the downstream and upstream samples.

Monitor well samples were collected using a stainless-steel or Teflonbailer, or a Johnson-Keck submersible pump. Each of the wells was purgedof standing liquid before sampling. A minimum of one well volume wasremoved from the shallow wells, while at least three well volumes wereremoved from the bedrock wells. Sampling was performed immediatelyfollowing the purging of the well. Samples for oil and grease analysiswere collected from the top of the wells with a bailer, while all othersamples were collected from the bottom of the wells.

The bailers and pump were decontaminated between wells and a new sectionof nylon cord was used for each well. The samples were preserved, asappropriate, after collection. Groundwater samples for metals analysiswere filtered on-site. Duplicate and blank QA/QC samples were alsocollected for each round of water sampling.

The surface water samples were analyzed for the indicator parameters (pH,TOC, oil and grease, and specific conductivity), as well as volatile andsemi-volatile HSL compounds, pesticides, HSL metals, total iron, ferrousiron, TOX, S03, and SO*. The surface water samples were not filtered.

Samples from the shallow wells (AW) were analyzed for pH, TOC, oil andgrease, and specific conductivity, while samples from the TAT shallowwells (A) were analyzed for pH and specific conductivity only.

During the first sampling round, groundwater samples from DW-1, DW-2,DW-5, DW-6, and DW-8 were analyzed for the four indicator parametersonly, while samples from the remaining bedrock wells (DW-3, DW-4, DW-7,DW-9, and DW-10) were analyzed for the same parameter list describedabove for surface water samples. The analytical scheme was reversedduring the October sampling. Therefore, over the two rounds of samplingconducted, each bedrock well was analyzed once for the indicatorparameters and once for the expanded list of parameters.

The Hawk's well was analyzed for pH, TOC, oil and grease, and specificconductivity during each of the two sampling rounds.

F-21 AR00I2M

With the exception of pH and specific conductivity, all analyses wereperformed by the CLP. The pH and specific conductivity of the sampleswere determined on-s1te by WESTON personnel as soon as possible aftersample collection. A Haakebuchler pH stick was used to measure pH and aYSI Model 33 C-S-T meter was used to measure specific conductivity. Eachinstrument was operated in accordance with the manufacturer'sInstructions and calibrated frequently during sample analysis usingstandard reference solutions. The probes of each unit were alsothoroughly rinsed and cleaned between measurements to prevent cross-contamination of the samples.

INTRODUCTION ;

The findings offered in this report are based upon a generalreview of sample data, blank analyses results, surrogate andmatrix spike results, field duplicate analysis, targetcompound matching quality, and tentatively identifiedcompound results for 14 aqueous samples and 22 soil samplesanalyzed by one laboratory.

All samples were analyzed for volatile (VOA) organic HSLcompounds. In addition, the following aqueous samples wereanalyzed for base/neutral/acid extr actable (BNA) HSLcompounds and pesticides/PCB's (PEST) HSL compounds:

• BNA, 7 samples ...... CA708-CA711, CA966, CA970, CA971• PEST, 4 samples..... CA708-CA711

Note, the following 8 soil samples were unsuccessfullyanalyzed for BNA due to problems associated with the pH ofthe sample matrix, and were resubmitted for BNA analysisas SAS 2118: CA963-CA965, CA967-CA969, CA977 and CA982.

This case was received at the laboratory in 9 shipments overa period of 4 months (June - September 1985).

The attached data summary contains results only for HSLcompounds which were reported as detected. The completelist of compounds analyzed for, their results, andassociated detection limits are locatetl as Appendix B.

The data summary contains the following qualifier codes:

FINDINGS

VOLATILES

VOA analysis was completed between 9 and 23 days aftersampling. The maximum allowable holding time for aro-matic volatile compounds for an unpreserved sample is 7days .

VOA analysis was completed 23 days after sampling. Themaximum allowable holding time for volatile compoundsis 14 days.

Lab reagent blanks contained sufficient amounts ofmethylene chloride, acetone, 2-butanone, and benzene toquestion the aforementioned results. Note that mostsamples were analyzed after dilution, and that allsoils are reported on a dry weight basis, the concen-tration of each lab contaminant was multiplied by therelevant dilution factor and, in the case of soils,divided by the fraction of soil to adjust for moisturecontent. '

Chloroform was only found in aqueous samples servingas trip and field blanks. The source of the deionizedwater used to prepare these samples has been documentedas containing small amounts of chloroform by thelaboratory supplying the water.

2-butanone is a common contaminant in methanol, whichis used to prepare medium-level soil samples. Onlythe methanol-spiked blanks contained 2-butanone,therefore, only medium-level soil samples werequalified as not detected due to blank contaminationfor this compound. •

The response factor obtained for 2-butanone for theanalysis of sample CA973 was low (-0.043). The failureto detect 2-butanone under this condition does notconfirm its absence in the sample.

The percent difference (%D) between the 2-uutanonecontinuing calibration response factor and averageresponse factor from the initial calibration is greaterthan 25% for the analysis of these samples, (ie. Theresponse factor for 2-butanone was not linear duringthe continuing calibration.)

: - ' I 48.0013-17


Detection limits were qualified for one or more of thefollowing reasons:

(1) Response factor was not linear during the initialcalibration.

(2) Response factor was not linear during the con-tinuing calibration.

(3) Response factor was very low «0.05). Failure todetect a compound under this condition does notconfirm its absence in the samples.

BASE/NEUTRAL/ACID EXTRACTABLES

• Raw data for sample CA708 contained sufficient evidenceto indicate tentative identification of 2-methylphenoland 4-methylphenol at trace levels.

• Surrogate recoveries for all three acid extractablesurrogate compounds were outside «10%) the loweracceptance limits for sample CA710 and its respectivere-extraction. Failure to detect acid extractablesunder these conditions does not confirm their absencein the samples. A summary of surrogate recoveriescan be found as Figure 2 "BNA Surrogates of Appedix A.

• Individually, the response factors for BNA HSLcompounds were not all linear during initial andcontinuing calibration. Affected samples andrespective compounds which were qualified as estimated(UJ) are summarized in Figure 1 "Calibration Criteria"(page 4 of 4) of Appendix A.

• Chromatographic evidence for samples CA708 and CA709indicates the presence of a hydrocarbon envelope,which .ay interfere with the detection of low levelsof other compounds eluting in the same range (encom-passes approximately scans 1200-2400).

SUMMARY

This Quality Assurance Review has identified the followingareas of concern:

• 40 CFR 136 and contract holding time criteria exceeded.

• Small amount of laboratory contamination.

• Response factors for HSL compounds were not all linearduring initial and continuing calibration and/orproduced very low «0.05) response.

• Poor acid surrogate recovery in one sample.

QUALIFIERS

It is recommended that this data package be utilized only withthe following qualifier statements:

VOLATILES (VOA)

Ql) For the following aqueous samples, the reported detectionlimits for volatile aromatic compounds have been qualifiedas estimated (UJ): CA708-CA711, CA975, CA979, CA980, CA983,CA984. The maximum allowable holding time for thesecompounds was exceeded. The failure to detect aromaticcompounds under these .conditions does not confirm theirabsence in the original sample.

Q2) For aqueous sample CA975, the reported detection limits forall volatile compounds were qualified as estimated (UJ).The maximum allowable holding time for these compounds wasexceeded. The failure to detect volatile compounds underthese conditions does not confirm their absence in theoriginal sample.

Qualifiers (Con't)

Q9) The reported detection limits for many non-detected BNAcompounds were qualified as estimated values (UJ). Therespective compounds in each sample can be determined byreferring to Figure 1 "Calibration Criteria" of Appendix A.

Q10) For samples CA708 and CA709, the actual detection limits maybe higher than reported for compounds listed on the datasummary.from diethylphthalate through benzo(ghi)perylene.

FINDINGS

VOLATILES

Fl) VOA analysis was completed between 9 • and 23 days aftersampling. The maximum allowable holding time for aromaticvolatile compounds for an unacidified aqueous sample is 7days.

F2) VOA analysis was completed 23 days after sampling. Themaximum allowable holding time for volatile compounds is 14days.

F3) Lab reagent blanks contained sufficient amounts of methylenechloride, acetone, 2-butanone, and benzene to question theaforementioned results. Note that most samples were analyzedafter dilution, and that all soils are reported on a dryweight basis. The concentration of each lab contaminant wasmultiplied by the relevant dilution factor and, in the caseof soils, divided by the fraction of soil to adjust formoisture content.

Chloroform was only found in aqueous samples serving astrip and field blanks. The source of the deionized waterused to prepare these samples has been documented ascontaining small amounts of chloroform by the laboratorysupplying the water.

2-Butanone is a common contaminant in methanol, which isused to prepare medium-level soil samples. Only themethanol-spiked blanks contained 2-butanone, therefore, onlymedium-level soil samples were qualified as not detected dueto blank contamination for this compound.

1-23 &ROOI323

Findings (Cont'd)

F4) The response factor obtained for 2-butanone for the analysisof sample CA973 was low (0.043). The failure to detect2-butanone under this condition does not confirm its absencein the sample.

F5) The percent difference (%D) between the 2-butanonecontinuing calibration response factor and average responsefactor from the initial calibration is greater than 25% fthe analysis of these samples. (ie. The response factor fc*2-butanone was variable during the continuing calibration).

F6) Detection limits were qualified for one or more of thefollowing reasons:

(1) Response factor was variable during the initialcalibration.

(2) Response factor was variable during the continuingcalibration.

(3) Response factor was very low (<0.05). Failure todetect a compound under this condition does not confirmits absence in the samples.

BASE/NEUTRAL/ACID EXTRACTABLES

F7J Raw data for samples CA708 contained sufficient evidence toindicate tentative identification of 2-methylphenol and4-methylphenol at trace levels.

F8) Surrogate recoveries for all three acid extractablesurrogate compounds were outside (<10%) the lower acceptablelimits for samples CA710 and its respective re-extraction,indicating possible matrix interference.

Some considerations for selecting a method follow:Extraction/analysis procedures need to be effective forextremely acidic samples (ie pH<2). Continuous extractionprovides better phenol recovery than separatory funnelextraction. An analytical method such as EPA 1625B "Semi-Volatile Organic Compounds by Isotopic Dilution GC/MS"could provide more effective recovery data for a wider rangeof samples/compounds than the CLP-required MS/MSD.

Q5) For samples CA715, CA715 and CA716RE, the actual detectionlimits may be higher than reported for compounds listed onthe data summary from diethylphthalate throubenzo(ghi)perylene.

FINDINGS

Fl) Lab Method Blanks contained sufficient methylene chloride,acetone, 2-butanone, and toluene to question theaforementioned results.

Both field and trip blanks contained sufficient amounts ofphenol to question the aforementioned results. Note,however, site contamination with phenol has been documentedfrom previous site investigation. No phenol was found inthe laboratory blanks.

F2) The response factor for bromomethane indicates the responsewas not linear during the initial calibration.

F3) The response factors for bis(2-chloroisopropyl)-ethex,hexachlorocyclopentadiene, 4-nitrophenol, 4-nitroaniline,indeno(l,2,3-cd)pyrene and dibenzo( ah) anthracene werevariable during the continuing calibration. (See Figure 1"Calibration Criteria" of Appendix A).

F4) All three acid surrogate recoveries for samples CA712,CA714, and CA715 were outside (0-3%) the lower acceptancelimits. On re-extraction/reanalysis of samples CA712 andCA715 (insufficient sample remained for reanalysis ofCA714), 2 of 3 surrogates were still outside the lower QCacceptance limits. Failure to detect acid extractablesunder these conditions does not confirm their absence in thesamples. This may be in part due to matrix interference,but also in part to analytical technique, as recoveries werebetter (although still low) in the reextracted samples.Better phenol recoveries can be obtained using continuousextraction rather than separatory funnel extraction. It isnot known which technique was used for this, analysis (bothare acceptable under this contract).

Case 4969Page 4 of 5(Revision A. 3/86)

Base/neutral surrogate recovery for nitrobenzene-cU insamples CA713, CA714,and CA716, as well as in there-extraction/reanalysis of CA716, was outside (0-2%) thelower QC acceptance limit. (Insufficient cample was avail-able for reanalysis of samples CA713 and CA716). Failure todetect nitroaromatic compounds under these conditions doesnot confirm their absence in the samples. Based on accept-able recoveries of the other two base/neutral surrogates,other groups of compounds in this fraction may be accept-able. Polynuclear aromatic hydrocarbons are probablyacceptable. Phthalate esters, chlorinated hydrocarbons,haloethers and nitrosamines require additional informationto make a judgement.

Field Blank CA717 and Trip blank CA718 had acceptablerecoveries for all surrogates. A summary of surrogaterecoveries can be found as Figure 2 "Water Surrogate PercentRecovery Summary" of Appendix A.

In addition to poor surrogate recovery, re-extracted BNAsamples CA712RE, CA715RE, and CA716RE were completed 10-11days after sampling. The recommended holding time for BNAcompounds is 7 days to extraction. These data are presentedas confirmation of positive identifications made in theoriginally extracted sample.

«F5) Chromatographic evidence for samples CA715, CA716 andCA716RE indicates the presence of a hydrocarbon envelope,which may interfere with the detection of low levels ofother compounds eluting in the same range (Hydrocarbonenvelope encompasses approximately scans 2100-3500).

F6) DDT was found in the field blank at 7.5 times the detectionlimit. No other samples or laboratory blanks contained thiscompound.

SUMMARY

This Quality Assurance Review has identified the following areasof concern:

• Laboratory contamination in method blanks.

• Possible matrix interference for BNA compounds indicated bypoor surrogate recovery (0-3%) for BNA surrogate compoundnitrobenzene-dc and all 3 acid surrogates.

* Poor instrument response to 2-butanone.

VOA analyses vere completed between 7 and 11 days aftersampling. The recommended holding times for volatilearomatic compounds for an unacidified sample is 7 days.Note that although samples C7638, CB902, and CB903 verealso analyzed 9 and 11 days after sampling, theseunpreserved samples each had pK<2, meeting the 14 dayrecommended holding time for acidified sample.BNA extractions for samples C7638 and C7639 werecompleted 8 days after sampling.

B. Surrogate recoveries for base/neutral compoundswere outside the lower acceptance limits for samplesC7638, C7639, CB902 and CB903. On initial analysis,there was no recovery of nitrobenzene-de in any of the4 samples and low recovery for terphenyl-d-. in samplesC7638 and CB902. The reanalysis of these samples hadno recovery of nitrobenzene-d- in samples C7638RE,C7639RE, CB903RE and only 2% recovery of nitro-benzene-dg in sample CB902RE. Terphenyl-d.. recovery .was within acceptance limits on reanalyzed Samples.

Failure to detect nitroaromatic compounds under theseconditions does not confirm their absence in thsamples, as actual detection limits may be substantially higher than reported. Based on acceptable recover-ies of the other two base/neutral surrogates, othergroups of compounds in this fraction may be acceptable.Polynuclear aromatic hydrocarbons are probably accept-able. Phthalate eaters, chlorinated hydrocarbons,haloethers, and nitrosoamines, require additionalinformation to make a judgement.

Field blank CB906 and trip blank CB905 had acceptablerecoveries for all surrogates. A summary of surrogaterecoveries can be found as Figure 2 "Water SurrogatePercent Recovery Summary" of Appendix A.

In order for resampling/reanalysis to provide additonalinformation, an alternate method should be requestedwhich takes into account the extremes in the matrixthis site. Extraction/analysis procedures need to u-effactive for extremely acidic samples (ie pH<2). Ananalytical method such as EPA 1625B "Semi-VolatileOrganic Compounds by Isotope Dilution GC/MS" couldprovide more effective recovery data for a wider rangeof samples/compounds than the CLP-required MS/MSD.

C. Individually, the response factors indicate that theresponse for VOA and BNA HSL compounds were not alllinear during initial calibration, were variable duringcontinuing calibration, and/or produced very low(<0.05) response. Affected samples and respectivecompounds which were qualified as estimated (UJ) aresummarized in Figure 1 "Calibration Criteria" ofAppendix A.

F2) Lab Method Blanks contained sufficient amounts of methylenechloride, acetone, 2-butanone,and bis(2-ethylhexyl)phthalateto question the aforementioned results. Note that VOAsamples C7638, C7641, CB901, CB902 and CB903 were analyzedafter dilution. The concentration of each lab contaminantwas multiplied by the relevant dilution factor.

F3) The response factor for acetone was variable during thecontinuing calibration.

F4) The response factors for benzyl alcohol and benzoic acidindicate that the response was not linear during the initialcalibration and/or was variable during the continuingcalibration.

SUMMARY

This Quality Assurance has identified the following areas ofconcern: .

INTRODUCTION

The findings offered in this report are based upon a reviewof all available sample data, blank results, matrix spikeand duplicate analysis results, calibration data, andquality assurance documentation.

All samples were aqueous and were analyzed for total organiccarbon (TOC) and for oil and grease (0/G). In addition,samples 13, 14, 22-29 (also designated as MCD286-MCD290,MCD301 and MCD303-MCD306) were analyzed for total organichalides (TOX), sulfite (SO "*), sulfate (SO ), andferrous iron (Fe ). No results were reported for sample7 (requested TOC and O/G) due to sample matrix problems..

QUALIFIERS


• The results which may be quantitatively questionable arelisted below:

Constituent Samples with Questionable Results

TOX (A) MCD287, MCD283, MCD304, MCD305(B) MCD286, MCD301, MCD303

The above results under (A) for TOX analyses aredesignated questionable since there is evidence toindicate that the reported sample data may representmaximum values in these samples.

AR001336

Case 5079/SAS 1971CPage 2 of 3

The above results under (B) for TOX analyses aredesignated questionable since there is evidence toindicate that the reported samples data may representminimum concentrations,, and that the actual TOXconcentration in the sample may be higher thanreported.

The results which may be qualitatively questionable are.listed below:


Sulf ite 27, 29

The aforementioned results were designated questionable(UJ) since there is evidence to doubt the presenceof these constituents at any concentration less than orequal to the levels reported. However, it can beassumed that concentrations significatly greater thanthe levels reported for these samples cannot.be present.

FINDINGS

The recovery of TOX in the matrix spike (sample MCD268+)is 196%. All calculations appear to be correct assubmitted. This high recovery may indicate a high biasfor TOX values reported in the referenced samples .

The recovery of TOX in the matrix spike (sample MCD301)is 46%. The calculations appear to be correct assubmitted. This low recovery may indicate a low biasfor TOX values reported in the referenced samples.

Field blank sample analysis revealed the presence ofsulfite.

TOC was measured in field blanks at levels less than orequal to 1 mg/L. Although sample results are notaffected at these levels , the presence of TOC in thefield blanks indicate the presence of an unknownconcentration of organic contamination associated withsample collection.

SUMMARY

This Quality Assurance review has indicated the followingareas of concern:

• Poor (both high and low) matrix spike recoveries for thereferenced sample for TOX analyses.

• The presence of field contamination in samplescollected for TOC analysis.

• Ferrous iron should be analyzed as soon as samples arereceived due to the change in ferrous to ferric ratiowith time. Ferrous iron was analyzed one month aftercollection.

• Results for selenium in all samples and for tin insamples MCD286, MCD301 and MCD303 have been qualified asunusable (R). Failure to detect selenium and tin inthese samples does not confirm their absence. Actualdetection limits may be higher than reported.

FINDINGS

• Results for diluted sample analysis for aluminum,beryllium, calcium, cobalt, copper, lead, silver, sodiumand zinc do not agree within 10% of the originalanalysis, indicating a possible chemical or physicalinterference effect.

High matrix spike recovery was reported for cadmium(130%).

• Low matrix spike recovery was reported for thallium (68%,60%, and 40%, respectively) in three separate spikedsamples and for lead (42%) in one of three spiked samples

• No matrix spike recovery (0%) was reported for seleniumin three of three spiked samples and for tin in one ofthree spiked samples. This condition indicates thepossibility that false negatives exist.

SUMMARY OF PREVIOUS FINDINGS

APPENDIX M

SUMMARY OF PREVIOUS FINDINGS

M.I GENERAL .

The following subsections summarize relevant .data and results from paststudies conducted at the Bruin Lagoon site. Most of the informationpresented is taken from the January 1982 RI/FS report. A comparison ofthe previous findings with those of the present work 1s made to determineif site conditions have changed significantly over the past four years.

M.2 AIR MONITORING

Air monitoring conducted during the 1981 remedial investigation of BruinLagoon revealed no detectable levels of organics, SOp, HpS, HC1, orHCN In the ambient air at the site. Organic vapors were detected withinone well boring during drilling operations; however, no detectable levelswere found in the ambient breathing zone at this location. It should benoted that no borings were constructed through the open lagoon during theinitial RI. As a result, the trapped gases below the crust were notencountered.

A1r monitoring performed during WESTON's field work in June 1984 includedambient and downhole sampling at the four locations where borings wereInstalled in the lagoon and completed below the crust. Ambientmonitoring showed no detectable levels of H2S or methane. The analysisof air bag samples collected 5 feet into the borings showed the presenceof HgS, COp^ methane, and aromatic.hydrocarbons. SOp was notdetected in the downhole samples. A sample from B-l had an HpSconcentration of greater than 1,000 ppm. Based on the results of samples

'

M-l AKOOI365

collected by 1mp1ngers, it was concluded that HpS was present ataverage levels of approximately 300 to 400 ppm and that Initialconcentrations could be greater by an order of magnitude, or more.Impinger analysis also indicated HF and HC1 were not (as a mist) present.

The results of the current air monitoring at Bruin Lagoon are generallyconsistent with the findings of the previous site work. The availableinformation shows that no detectable levels of contaminants are presentin the ambient air at the site; however, the potential does exist for therelease of gases during activities which disturb the site surface. Suchactivities are likely to occur during a remedial cleanup.

The air monitoring work indicates that the gases released from thesubsurface may include organic vapors, S02, H2$, C02, or methane atvarying concentrations. The elevated levels of H2S detected indownhole grab samples collected during the June 1984 work were not foundin large amounts during the most-recent drilling operations. Furtherdiscussion of these findings is provided in Subsection 6.4.6, which'covers the results of subsurface gas testing.

M.3 LAGOON SAMPLES

A summary of the organic and inorganic analytical results for the fourlagoon samples collected during the 1981 remedial investigation of BruinLagoon are presented 1n Tables M-l and M-2, respectively. These sampleswere collected from the upper layer of the lagoon.

Only a limited number of organic priority pollutant compounds weredetected in the lagoon samples, and they were found at concentrations inthe low ppb range. High levels of inorganic contaminants (ranging in thehundreds to thousands of ppm), however, were identified in the lagoonsludge samples. These included aluminum, calcium, iron, lead, magnesium,

manganese, sodium, and zinc. High concentrations of volatile solids (VS)and TOC (typical of asphaltlc sludges) were also identified. Significantconcentrations of surface-active detergents (MBAS) were detected in thelagoon samples as well.

Finally, the analyses showed that the sludge was highly acidic with a pHin the range of 2 to 3. The low pH of the sludge is also likely to havecontributed to the high Inorganics concentrations in the lagoon samples.The acidic conditions created by the lagoon may have liberated theconstituent cations of aluminum, calcium, iron, magnesium, and manganesefrom the wastes in the lagoon (ash, coal refuse, filter clay, and soil)and resulted in accumulations 1n the lagoon sludge.

The analytical results for the soil collected during the current RI, showthat they were composed largely of uhstabilized sludge; this agrees withthe previous characterization of the lagoon sludge. These samples showedthat this material has an extremely low pH, and contained a number ofinorganics and relatively few organic compounds.

Additional analyses of lagoon samples, as well as sludge contaminatedsoils, were conducted during the 1981 RI to evaluate the heating valueand potential incinerabllity of on-site wastes. The results of thisstudy are provided in Table M-3.

The results Indicate that the sludge generally has a high heating value.Samples taken from the middle of the lagoon had values of approximately12,000 Btu/lb. Heating values for some of the contaminated soil samplescould not be determined since they would not burn in the calorimetrytest. Halogen concentrations ranged from 2 to 23 mg/kg of chloride and,as such, are not viewed as a problem for incineration. The sulfurcontent was about 2.6 percent, a level that would not create significantair contamination during incineration.

Viscosity testing of the sludge samples was also performed. The materialshowed a great variability in viscosity with changing temperature. Itwas concluded that the highly viscous nature of the sludge would presentmaterials handling problems during the implementation of incineration andother remedial alternatives.

M.4 SOIL SAMPLES

The organic and inorganic analytical results for soil samples collectedduring the 1981 RI of Bruin Lagoon are summarized in Tables M-4 and M-5,respectively. Soil samples were collected from various depths during thedrilling of the 14 monitoring wells at the site, and the excavation ofthe 9 test pits from the covered lagoon areas.

Tables M-6 and M-7 provide summaries of the organics and Inorganics,respectively, for the soil samples collected during the 1984 emergencyaction. These samples were collected at various depths during theinstallation of well A-l. Additionally, pH versus depth data is providedin Table M-8 for the shallow wells installed during the 1984 emergencywork. •

The previous data show that only a few organic compounds were positivelyidentified in the soil samples, and that they were found at concentrationlevels at or below 1 ppm. Comparison of the 1981 and 1984 results showthat many of the same organic compounds were identified during both fieldinvestigations. PCB's were detected during the 1981 RI in soilsassociated with the abandoned storage tank areas. These soils wereremoved with the tanks during the remedial cleanup that took place at thesite.

Inorganic analytical results from the previous studies compared well andshowed the presence of high levels of aluminum, calcium, iron, lead,magnesium, manganese, potassium, and sodium in most of the samples.Arsenic, barium, and zinc were also detected in many of the soil samples,but at lower concentrations.

Analytical results for the current remedial investigation showed fewerorganic compounds detected in the soil samples. Comparableconcentrations of metals were found in the soil samples analyzed duringeach of the site investigations.

The data for pH versus depth for the shallow wells installed during the1984 emergency work are consistent with the results obtained during thepresent remedial investigation. These data show that the unstabilizedsludge in the lagoon has a very low pH and that the lagoon is comprisedof a heterogeneous mixture of materials which vary both horizontally andvertically throughout the site. The 1984 pH data also indicate thatcontamination has penetrated the top of the bedrock which underlies thesite.

M-16 £8001380

In addition to the chemical analyses of soil samples during the 1981remedial investigation, selected soil samples were tested for physicalproperties which included natural moisture content, plasticity, and grainsize distribution. The moisture content of the four samples testedbetween 12 and 29 percent. The samples had low plasticity with theplasticity Indices ranging between 10 and 11 percent. Grain sizedistribution classified the soils tested as silty-clays with sand andgravel.

M.5 CRUST SAMPLES

The results of inorganics analysis of a crust sample collected duringWESTON's June 1984 work are presented in Table M-9. The sample wascollected from boring B- 2 at a depth of approximately 14 feet. Thematerial had a low moisture content and a high aluminum content.Elevated concentrations of barium, calcium, magnesium, and lead were alsodetected.

M.6 SUBSURFACE GASES

The analytical results for the subsurface gas samples collected from the13 shallow wells installed during the 1984 emergency action are presentedin Table M-10. A variety of analytical techniques were used to determinethe composition of the gases. Various concentrations of volatileorganics, S02, HpS04, and methane were found in the wells. Itshould be noted that H2S was not detected 1n the samples. Prior to.this sampling, however, air monitoring performed on two existing wellsduring July 1984 revealed the presence of hydrogen sulfide gas at greaterthan 200 ppm by Drager detection tube and greater than 50 ppm byreal-time instrumentation.

Methane was observed in all the wells with a concentration range of 2.6 -4,400 ppm. Wells A-3, A-4, A-5, and A-6 had the highest methaneconcentrations. These values showed good correlation with the organics/CH. levels measured in the field by the OVA. Analysis of carbon tubesamples collected from each well for volatile organic compounds showednone to be present. Additionally, samples from each well were analyzedfor methyl, ethyl, propyl, and t-butyl mercaptan and these compounds werenot detected in any of the wells.

Drager detector tubes showed the presence of sulfur dioxide in 11 of the13 wells. Wells A-2, A-8, A-10, and A-13 had S02 concentrations ofgreater than 100 ppm. Subsequent laboratory analysis of impinger samplesconfirmed the presence of elevated levels of S02 in wells A-8 andA-10. Additional laboratory analysis for each sample indicated thatS02 was present at concentrations less than 0.002 percent. Sulfuricand mist was found in wells A-5, A-8, A-10, and A-13.

Laboratory analysis of the samples also showed that gases from each wellcontained about 21 percent 02 and approximately 78 percent N2.Carbon dioxide varied from well to well, ranging from 0.024 percent inwell A-12 to 1.37 percent in well A-3. Levels of C02 and CH4 foundin particular wells indicate that biological processes may be occurringin the subsurface.

M-20

The results of the 1984 sampling of subsurface gases at the Bruin Lagoonsite showed that elevated levels of S02 and the presence of H2S04mist were limited to three wells (A-8, A-10, and A-13). Additionally,reactions and gas releases occurred during the installation of each ofthese wells. Elevated levels of SOp were also detected in well A-2.These wells are all located within 50 feet of one another and, as aresult, the data suggests that this area of the site is a "hot spot" withrespect to potentially harmful trapped subsurface gases.

Analytical results for subsurface gas samples collected from wells A-lthrough A-13 during 1984 and 1985 are summarized for comparison in TableM-ll. A period of approximately one year elapsed between the 1984sampling and the first sampling round conducted in 1985. Comparison ofthe results shows them to be in general agreement and confirms thepresence of a "hot spot" area at the site. Sulfur dioxide was detectedduring the 1985 samplings in only five wells; these included A-2, A-8,A-10, and A-13, as well as A-l. It should be noted that well A-l islocated about 30 feet south of well A-2, and approximately 45 feet westof wells A-8, A*10, and A-13. This additional well provides furthersupport for the presence of a "hot spot" area located in the central partof the site. Additionally, sulfuric add mist and hydrogen sulfide wereeach detected in only one well during the current remedial investigation,A-10 and A-13, respectively.

Carbon dioxide and methane results for the September 1985 sampling ofwells A-l through A-13 are in agreement with the values measuredpreviously. The data confirm the presence of increased C02 and CH4levels in certain wells at the site. Also, it should be noted that theoxygen content in wells A-3 and A~4 decreased dramatically below that ofair during the year between samplings. This Information, coupled withthe elevated levels of C02 and CH. measured in each of these wellsduring September 1984 and September 1985 samplings, confirms thepossibility that biological degradation may be occurring below thesurface of the site.

M.7 SURFACE WATER

Tables M-12 and M-13 summarize the analytical results for organics andinorganics, respectively, for one set of surface water samples collectedduring the 1981 remedial investigation of Bruin Lagoon. Samples werecollected at three locations in the South Branch of Bear Creek, as wellas in the small feeder stream flowing along the southern boundary of-thesite.

The results for the feeder stream indicated that it was not contaminatedat that time. No detectable levels of organic priority pollutants werefound and only background concentrations of natural constituentinorganics were measured. These data indicate that the feeder stream hadlittle impact on the water quality of the South Branch at the time ofsampling.

With the exception of phenol, the results for the three samples collectedin Bear Creek indicated that specific organic compounds (see Table M-12)are at or below detection levels. Phenol showed a 10-fold increasebetween the upstream and downstream sampling locations (37 ppb. to 310ppb); however, the samples were collected on different days andconclusions cannot be drawn from the data at this time.

Organics results for the two rounds of surface water samples collectedduring the current RI showed general agreement with the previousfindings. Again, phenol was the only organic compound to be positivelyidentified and at the same levels as previously found. The concentrationincrease of phenol across the site, however, was not as great as thatfound during the 1981 study.

The inorganics results for surface water samples collected during the1981 investigation showed significant increases in COD and TOC in BearCreek between upstream and downstream sampling stations. The upstreamsamples indicated that the creek contained greater than 1 ppmconcentrations of aluminum, barium, magnesium, and manganese; and greaterthan 50 ppm concentrations of calcium, iron, and sodium. The siteappeared to add to the surface water pollution, although contaminantIncreases of less than one order of magnitude were observed.

The Inorganics surface water-results for the present remedialinvestigation generally confirm the previous findings. The same metalswere identified in the same concentration ranges found during the 1981sampling. Slight increases in concentrations were usually noted in thedownstream samples as well. It should be noted that TOC showed a markeddecrease between the studies with average stream concentrations of 1,770mg/L for the 1981 samples, and 85 mg/L for the 1985 samples.

M-27AfiOOI39l

In summary, available information from the surface water samplingperformed for the South Branch of Bear Creek, in the Immediate area ofBruin Lagoon, confirms the highly polluted nature of the stream, andshows that the site appears to have only a limited impact on the waterquality of the creek.

M.8 GROUNDWATER

The results of organic and inorganic analyses performed for groundwatersamples collected during the 1981 RI are summarized in Tables M-14through M-19. These tables provide results for samples collected fromshallow and bedrock wells installed during the RI as well as for samplescollected from three residential wells located on adjacent propertiesdirectly to the west of the site. The locations of 14 monitor wellsinstalled during the 1981 RI are shown in Figure M-l. It should be notedthat all of these wells, except Wells 1 and 4, were abandoned in late1983 to early 1984 during the remedial cleanup work.

As indicated in Tables M-14 and M-19, only a limited number ofsemivolatile organic compounds, were detected in the shallow and bedrockwell samples from 1981. No volatile or pesticide/PCB compounds wereidentified. The compounds that were quantified were generally found inthe 10 to 25 ppb range. No substantial differences in organicconcentrations were observed between the shallow and bedrock wellsamples. The organic results showed that the site has a limited impacton groundwater downgradient of the lagoon.

Samples collected from shallow wells during the present study were notanalyzed for organic compounds. The organics results for groundwatersamples collected from bedrock wells during September and October 1985,however, are consistent with the previous findings. These results showedthe presence of a limited number of semivolatile compounds in the 5 to 25ppb range. Additionally, a few volatile compounds were detected in thebedrock well samples. The results of the 1985 sampling confirm thatlimited organics contamination has occurred in the bedrock aquiferdowngradient of the site. The results also show negligible organicsconcentrations in bedrock wells at Bear Creek across from the site.

The inorganics results in Tables M-15 and M-17 show the presence ofnumerous compounds at the ppm level in both the shallow and bedrock wellsamples collected in 1981. The metals identified in every groundwatersample collected included aluminum, barium, calcium, chromium, cobalt,copper, iron, magnesium, manganese, nickel, sodium, vanadium, and zinc.Many of these same metals were found at elevated concentrations in thesludge and soil. The inorganics results showed that although contaminantlevels varied throughout the site, localized contamination existsdowngradient from the lagoon. It should be noted that the 1981 resultsalso showed existing elevated levels of soil constituent inorganics inthe background monitor wells.

M-36 ftRQOUQO

Primary drinking water standards for arsenic, barium, cadmium, chromium,lead, and mercury were exceeded within the 1981 groundwater samplescollected from wells immediately downgradient of the site. The highestlevels of inorganic comtamlnants were noted in Well 10, a shallow welllocated north of the lagoon. In general, the shallow groundwatercontained greater contaminant levels than,deeper groundwater flowingwithin the bedrock. Approximately one order of magnitude differenceexisted between the organic pollutants in the shallow and bedrockgroundwater. The 1981 results are supported by the inorganics dataobtained for bedrock aquifer samples collected as part of the presentremedial investigation. Samples collected from shallow wells during thefall of 1985 were not analyzed for metals. The same metals wereIdentified in the bedrock samples in the same concentration ranges asfound in 1981. The most recent inorganic results confirmed the existenceof localized contamination downgradient of the site, as well as thepresence of elevated levels of soil constituents in the backgroundmonitor wells. These results also showed that primary drinking waterstandards for several metals were also exceeded in the bedrock wells.

Water quality results for the three residential wells sampled during the1981 remedial investigation are summarized in Tables M-18 and M-19.These data revealed essentially no contamination of the deep aquifer Inadjacent drinking water wells due to the presence of Bruin Lagoon. Noneof the priority pollutant organic compounds was positively identified,and only naturally occurring background concentrations of inorganics weredetected. No sampling of adjacent resident water supplies was performedas part of the 1985 RI. -

A summary of inorganics results for liquid samples collected from shallowWells B-l through B-4 during the June 1984 investigation is presented inTable M-20. These results showed that the liquids above the bedrock inthe immediate vicinity of the open lagoon had an extremely low pH (lessthan 1.0), as well as high values for specific conductivity, sulfate, andTOC. Additionally, these liquids contained various metals at elevatedconcentrations. No organics analyses were performed for these samples.

The indicator parameter results for liquid samples collected from shallowwells during September and October 1985 show good agreement with theprevious findings. Samples collected from shallow wells in the vicinityof the four boring locations had pH, specific conductivity, and TOCvalues similar to those determined during the June 1984 work. Sulfateand metal analyses were not performed for liquid samples collected duringthe current RI.

Transmittal.Results of Geotechnical Testing

Bruin Lagoon Project

Dear Mr. Oaks:

IT Analytical Services (ITAS) is pleased to submit the enclosed testresults for geotechnical testing of the samples received in our laboratoryon August 13, 1985* As you can see in the attached test results, weexperienced problems in consolidation testing in Boring AW4 at 11.5' andBoring SB AA at 9.4*. These two samples do not show any indication ofsecondary consolidation which is required for the consolidation theory tobe appropriate. We, therefore, have presented these tests in the form ofraw data and have performed no further data reduction or Interpretation.This was done after subsequent phone conversations with Jamie Kaufmann ofRoy F. West on. All other data presented herein is in compliance with the.scope of work and should require no further explanation.

We have very much appreciated this opportunity to work with your organiza-tion and look forward to working with you again.

Respectfully submitted,

David R. Backstrom, ManagerGeotechnical Laboratory
