STAGE 2 VAPOUR MONITORING: JUNE 2015

1.0 INTRODUCTION Golder Associates Pty. Ltd. (Golder) was commissioned by the Environment Protection Authority (EPA; South Australia) to undertake a vapour monitoring programme in Beverley centred around the former Electrolux facility on Pope Street, Beverley, South Australia.

The monitoring programme consisted of the following:

soil vapour sampling at 15 locations by SUMMA canister

soil vapour sampling at 47 locations by Waterloo membrane (WMS) passive samplers

service pit sampling at 8 locations by Radiello passive samplers

crawl space sampling at 5 locations by SUMMA canister and Radiello passive samplers

All samples were collected during the period 2 June 2015 – 12 June 2015 and analysed for volatile organic compounds (VOCs). Monitoring locations are presented in Appendix A.

7 July 2015 Report No. 1418522-010-R-Rev0 1

STAGE 2 VAPOUR MONITORING: JUNE 2015

2.0 TEST METHODS Golder holds National Association of Testing Authorities (NATA) accreditation for the sampling methodologies used in this programme (NATA Laboratory Accreditation No. 1910).

2.1 Soil Vapour Monitoring 2.1.1 SUMMA Canister The procedure for sampling VOCs using evacuated canisters, and for the subsequent analysis, is described in USEPA Method TO-15. The method involved the collection of whole air samples in passivated electropolished stainless steel canisters. The VOCs were subsequently separated by gas chromatography (GC), and measured by mass selective (MS) detector or multi-detector techniques.

The SUMMA canister method is summarised as follows:

The soil vapour bore and sampling train were purged at 50 ml/min with a volume equal to three times the total bore and sampling train volume, immediately prior to sample collection.

Bores were purged using a calibrated rotameter and vacuum gauge to monitor vapour flow.

The sampling train consisted of PTFE tubing and a SUMMA canister.

Samples were collected in low volume (1 litre) SUMMA canisters to reduce the possibility of atmospheric breakthrough and a false negative result.

SUMMA canisters were equipped with a flow restricting orifice and a vacuum gauge to enable sampling over a twenty minute period, again minimising the potential for atmospheric breakthrough.

Sampling was conducted in accordance with Golder Technical Procedure 37, “Soil Gas Bore Sampling.”

Sample analysis was conducted by Eurofins Air Toxics Ltd. (Eurofins), in accordance with modified USEPA Method TO15. Eurofins is accredited by NELAP/Florida Department of Health for analyses of VOCs by the described method (Laboratory Accreditation No. E87680). Eurofins accreditation is recognised by NATA under the Mutual Recognition Arrangement (MRA) network.

Details of the soil vapour bores from which the samples were collected are provided in the previous Golder report titled Groundwater and Soil Vapour Data Report – Beverley Assessment Area, South Australia, dated 27 May 2015.

2.1.2 WMS Passive Sampler The procedure for installation and sampling VOCs using WMS is described as follows:

Bores with a diameter of 75mm were drilled by hand auger to a target depth of 1m below ground surface (BGS). Where refusal was encountered, a minimum depth of >0.5m was achieved.

Bores were sealed using a foam bung inside a plastic sleeve, a concrete paving brick on top of the borehole and bentonite prior to installation of WMS.

Low uptake WMS were installed at a target depth of 0.8m to ensure adequate clearance from soil. An expandable foam bung inside a plastic sleeve was used to seal the probe at the target depth (see Figure 1).

Samples were collected after a nominal 7 day period.

Sample analysis (solvent extraction) was conducted by Eurofins, in accordance with modified USEPA Method TO17.

STAGE 2 VAPOUR MONITORING: JUNE 2015

Figure 1: Installation of WMS for Soil Vapour Sampling

2.2 Service Pit Monitoring 2.2.1 Radiello Passive Sampler Sampling was conducted in accordance with Golder Method No. P13, “Passive Gas Sampling: In Ambient Air by Radiello Passive Samplers.” Radiello samplers were installed approximately 0.5m BGL within service pits and storm water drains, hanging free-standing from metal wire. The samplers were left in place for approximately a one week period.

Sample analysis was conducted by Eurofins, in accordance with modified USEPA Method TO17. Airborne contaminant concentrations were calculated using the reported analyte mass and measured sample volume provided to Eurofins and these calculations were verified by Golder in accordance with Golder Method No. P13.

2.3 Crawl Space Air Monitoring 2.3.1 SUMMA Canister The procedure for sampling VOCs using evacuated canisters, and for the subsequent analysis, is described in USEPA Method TO-15.

The sampling train consisted of clean PTFE tubing, flow controller and a 6 L SUMMA Canister. Samples were collected over a nominal 24 hr period at ground level within the crawl spaces of selected houses.

Sample analysis was conducted by Eurofins Air Toxics Ltd. (Eurofins), in accordance with modified USEPA Method TO15.

2.3.2 Radiello Passive Sampler Sampling was conducted in accordance with Golder Method No. P13, “Passive Gas Sampling: In Ambient Air by Radiello Passive Samplers.”

Radiello samplers were installed using a backing plate at ground level within the crawl spaces of selected houses. The samplers were left in place for approximately a one week period.

Sample analysis was conducted by Eurofins, in accordance with modified USEPA Method TO17. Airborne contaminant concentrations were calculated using the reported analyte mass and measured sample volume provided to Eurofins and these calculations were verified by Golder in accordance with Golder Method No. P13.

3.0 MEASUREMENT UNCERTAINTY

3.1 SUMMA Canister USEPA Method TO-15 cites the measurement uncertainty and precision for two ambient air quality studies conducted in the United States of America. The average replicate precision for a range of 16 compounds in both studies was 15%.

The reported measurement uncertainties for these studies ranged between ± 4% and ± 31%. The average measurement uncertainty for both studies for the range of 16 compounds was ± 11%.1

3.2 Radiello Passive Sampler The measurement uncertainty for VOC determination using Radiello passive samplers varies for each compound is in the range ±1.1 – 14.5% at 95% confidence interval.

3.3 WMS Passive Sampler Soil vapour sampling by WMS is considered to be a semi-quantitative methodology. All concentrations reported are indicative only.

STAGE 2 VAPOUR MONITORING: JUNE 2015

5.0 QUALITY CONTROL MEASURES The quality control (QC) measures taken throughout the monitoring program include replicate sampling, method blanks, analytical recoveries, leakage monitoring and sampling media certification.

Details of the quality control measures taken, together with the data quality objectives (DQO) are listed in Table 5.

Table 5: QC Measures

Measure Frequency Quality Objective (limit)

Field replicates/duplicates 1 in 10 samples or per event <100% RPD

Field blanks 1 in 10 samples or per event NA

Canister cleaning 10% canisters to be certified clean NA

Laboratory Control Surrogate 1 in 20 samples Method Specific

Laboratory Control Sample (LCS) 1 in 20 samples Method Specific

Laboratory Blank 1 in 20 samples NA

Laboratory Control Sample Duplicate (LCSD) 1 in 20 samples Method Specific

Continuing Calibration Verification (CCV) 1 in 20 samples Method Specific

Tracer leakage rate Each sample (soil vapour by SUMMA canister) <10%

Notes:

RPD: relative percentage difference

Leakage rate: Csample/Cshroud (%)

Other quality control/quality assurance measures included in the programme are as follows:

Soil vapour sampling:

PTFE tubing and other sample train equipment was replaced for each bore to prevent cross contamination.

Test methods employed a minimum sample volume to avoid convective flow through unsaturated soils, which can cause an increase in vapour phase contaminant concentrations at the expense of other phases.

A small vacuum is maintained in canisters at the completion of sampling. This is recorded and verified by the laboratory prior to analysis to check that the integrity of the sample has been maintained (the canister has not leaked) during transit.

QA/QC data was assessed and found to be compliant with the programme objectives and therefore the results of the sampling programme are accepted as valid.

5.1 Field Replicates Field replicates were collected for soil vapour sampling by SUMMA canister on bores SV08-S and SV10-S.

2,2,4-Trimethylpentane (189%), Toluene (131%) and m,p Xylene (164%) were outside the DQO for bore SV10-S. Tetrachloroethene (148%) was outside the DQO for bore SV08-S.

It should be noted that primary and replicate samples were taken consecutively (not concurrently) which may account for some variation between results.

7 July 2015 Report No. 1418522-010-R-Rev0 10

STAGE 2 VAPOUR MONITORING: JUNE 2015

5.2 Field Duplicates A field duplicate (15-720) was collected for crawl space sampling by Radiello passive samplers. All compounds met the DQO.

5.3 Tracer Leakage Rates In order to detect the occurrence of atmospheric breakthrough, and hence a false negative result, a chamber constructed from inert materials (stainless steel, PTFE and polycarbonate) was placed over the top of the soil vapour bores during sampling. Ultra-high purity (UHP) helium (99.999 %v/v) was periodically bled into the chamber to maintain a concentration in the range 10%v/v to 90%v/v.

Atmospheric breakthrough is detected by measuring the tracer (helium) concentration in the samples and calculating a leakage rate. The leakage rate is defined as the fraction of the concentration of helium measured in the sample versus the average concentration in the chamber, expressed as a percentage.

A sample taken from sub-slab bore SV09-P1 (14%) was above the tracer leakage quality objective of 10%. Laboratory results for SV09-P1 have not been adjusted for tracer leakage and are considered indicative only.

Atmospheric breakthrough may occur during sub-slab sampling due to the close proximity of the probe to the surface and the magnitude of this breakthrough is influenced by the integrity of the surface material.

5.4 SUMMA Canister Vacuum Crawl space sample no. 15-659 was collected such that the canister was allowed to completely fill (the vacuum at the completion was recorded as 0” Hg). The sample integrity check was therefore not possible (it was not possible to determine whether the contents of the canister have mixed with ambient air during transit). The canister valve was closed tightly and an airtight cap was fitted on completion of sampling. It is therefore unlikely that the sample integrity was compromised between sampling and analysis.

5.5 Field Blanks Field blank sample nos. 15-654, 15-655, 15-708, 15-709, 15-710, 15-725 and 15-726 were collected to assess if contaminants were present within the sampling media and equipment.

Radiello and WMS passive samplers were exposed to atmosphere and immediately returned to their packaging. A sample of ambient air was collected in a SUMMA canister after passing through an activated carbon tube (to remove contaminants) and a standard sampling train (clean PTFE tubing and a flow controller). .

Hexane (0.25 µg/m3) was detected above reporting limit in Radiello field blank sample no. 15-726.

5.6 Laboratory Blanks Laboratory blanks were analysed to assess if contaminants were present within the laboratory instrumentation and sampling media.

Toluene (1.9 µg/m3) was detected above the reporting limit (0.5 µg/m3)in the WMS laboratory blank analysed on 18 June 2015 (Lab ID#: 1506321-21A).

5.7 Laboratory Analytical Recoveries The laboratory determines analytical recoveries from the sampling media by spiking the samples with surrogate standards, preparing laboratory control standards (LCS) and laboratory control standards duplicates (LCSD) and conducting continuous calibration verification.

Laboratory analytical recoveries that did not meet the DQO are presented in Table 6 below.

Eurofins | mgt (formerly mgt Labmark Environmental Laboratories)Workorder# 1506313

Five 6 Liter Summa Canister samples were received on June 17, 2015. The laboratory performed analysis via EPA Method TO-15 using GC/MS in the full scan mode.

This workorder was independently validated prior to submittal using 'USEPA National Functional Guidelines' as generally applied to the analysis of volatile organic compounds in air. A rules-based, logic driven, independent validation engine was employed to assess completeness, evaluate pass/fail of relevant project quality control requirements and verification of all quantified amounts.

The Summa canister for sample 34 W (2) (15-659) was leaking upon arrival. The client was notified and the analysis proceeded. Reported analyte concentrations are considered to be estimated.

Receiving Notes

There were no analytical discrepancies.

LABORATORY NARRATIVEPassive SE GC/MS

Eurofins | mgt (formerly mgt Labmark Environmental Laboratories)Workorder# 1506314

Sixteen Radiello 130 (Solvent) samples were received on June 17, 2015. The laboratory extracted the charcoal sorbent bed of the passive sampler using carbon disulfide. An aliquot of the extract was injected into a GC/MS for identification and quantification of volatile organic compounds (VOCs).

The mass of each target compound adsorbed by the sampler was converted to units of concentration using the sample deployment time and the sampling rate for each VOC. If sampling rates were calculated by the lab or the manufacturer, the concentration result has been flagged as an estimated value. Results are notcorrected for desorption efficiency.

There were no receiving discrepancies.

Receiving Notes

The uptake rates were corrected based on average field temperatures if provided. In the absence of field temperatures, the uptake rates determined at 25 deg C were used.

To calculate ug/m3 concentrations in the Lab Blank, a sampling duration of 11410 minutes was applied. The assumed temperature used for the uptake rate is listed on the data page. If the field temperatures were provided, the rate was adjusted in the same manner as the field samples.

All Quality Control Limit exceedances and affected sample results are noted by flags. Each flag is defined at the bottom of this Case Narrative and on each Sample Result Summary page.

The field blank sample FB2 (15-726) has reportable levels of Hexane present.

Analytical Notes

Nine qualifiers may have been used on the data analysis sheets and indicates as follows: B - Compound present in laboratory blank greater than reporting limit (background subtraction not performed). J - Estimated value. E - Exceeds instrument calibration range. S - Saturated peak. Q - Exceeds quality control limits. U - Compound analyzed for but not detected above the reporting limit. UJ- Non-detected compound associated with low bias in the CCV N - The identification is based on presumptive evidence. C - Estimated concentration due to calculated sampling rate

File extensions may have been used on the data analysis sheets and indicates as follows: a-File was requantified

LABORATORY NARRATIVEEPA Method TO-15

Eurofins | mgt (formerly mgt Labmark Environmental Laboratories)Workorder# 1506320A

Ten 1 Liter Summa Canister (100% Certified) and nine 1 Liter Summa Canister samples were received onJune 17, 2015. The laboratory performed analysis via EPA Method TO-15 using GC/MS in the full scan mode.

This workorder was independently validated prior to submittal using 'USEPA National Functional Guidelines' as generally applied to the analysis of volatile organic compounds in air. A rules-based, logic driven, independent validation engine was employed to assess completeness, evaluate pass/fail of relevant project quality control requirements and verification of all quantified amounts.

There were no receiving discrepancies.

Receiving Notes

Dilution was performed on samples SV0-1M (15-637), SV02-S (15-638), SV03-S (15-639), SV04-S (15-640), SV05-S (15-641), and SV10 S (15-650) due to the presence of high level target species.

All Quality Control Limit exceedances and affected sample results are noted by flags. Each flag is defined at the bottom of this Case Narrative and on each Sample Result Summary page.

Analytical Notes

Eight qualifiers may have been used on the data analysis sheets and indicates as follows: B - Compound present in laboratory blank greater than reporting limit (background subtraction not performed). J - Estimated value. E - Exceeds instrument calibration range. S - Saturated peak. Q - Exceeds quality control limits. U - Compound analyzed for but not detected above the reporting limit, LOD, or MDL value. See data page for project specific U-flag definition. UJ- Non-detected compound associated with low bias in the CCV N - The identification is based on presumptive evidence.

File extensions may have been used on the data analysis sheets and indicates as follows: a-File was requantified b-File was quantified by a second column and detector r1-File was requantified for the purpose of reissue

LABORATORY NARRATIVEModified ASTM D-1946

Eurofins | mgt (formerly mgt Labmark Environmental Laboratories)Workorder# 1506320B

Ten 1 Liter Summa Canister (100% Certified) and nine 1 Liter Summa Canister samples were received on June 17, 2015. The laboratory performed analysis via Modified ASTM Method D-1946 for Helium in air using GC/TCD. The method involves direct injection of 1.0 mL of sample.

Method modifications taken to run these samples are summarized in the table below. Specific project requirements may over-ride the ATL modifications.

Requirement ATL ModificationsASTM D-1946Calibration A single point

calibration is performed using a reference standard closely matching the composition of the unknown.

A minimum of 5-point calibration curve is performed. Quantitation is based on average Response Factor.

Reference Standard The composition of any reference standard must be known to within 0.01 mol % for any component.

The standards used by ATL are blended to a >/= 95% accuracy.

Sample Injection Volume Components whose concentrations are in excess of 5 % should not be analyzed by using sample volumes greater than 0.5 mL.

The sample container is connected directly to a fixed volume sample loop of 1.0 mL on the GC. Linear range is defined by the calibration curve. Bags are loaded by vacuum.

Normalization Normalize the mole percent values by multiplying each value by 100 and dividing by the sum of the original values. The sum of the original values should not differ from 100% by more than 1.0%.

Results are not normalized. The sum of the reported values can differ from 100% by as much as 15%, either due to analytical variability or an unusual sample matrix.

Precision Precision requirements established at each concentration level.

Duplicates should agree within 25% RPD for detections > 5 X's the RL.

Receiving Notes

There were no receiving discrepancies.

There were no analytical discrepancies.

LABORATORY NARRATIVEPassive SE GC/MS

Eurofins | mgt (formerly mgt Labmark Environmental Laboratories)Workorder# 1506321

Twenty WMS-SE samples were received on June 17, 2015. The laboratory extracted the charcoal sorbent bed of the passive sampler using carbon disulfide. An aliquot of the extract was injected into a GC/MS for identification and quantification of volatile organic compounds (VOCs).

The mass of each target compound adsorbed by the sampler was converted to units of concentration using the sample deployment time and the sampling rate for each VOC. If sampling rates were calculated by the lab or the manufacturer, the concentration result has been flagged as an estimated value. Results are notcorrected for desorption efficiency.

There were no receiving discrepancies.

Receiving Notes

If validated uptake rates were not available, rates were estimated by the vendor using the chemical's retention time on a nonpolar phase column. Chemicals that are poorly retained by the sorbent over the sampling duration may exhibit a low bias. All concentrations calculated using estimated rates are qualified with a "C" flag.

To calculate ug/m3 concentrations in the Lab Blank, a sampling duration of 10080 minutes was applied. The assumed temperature used for the uptake rate is listed on the data page. If the field temperatures were provided, the rate was adjusted in the same manner as the field samples.

All Quality Control Limit exceedances and affected sample results are noted by flags. Each flag is defined at the bottom of this Case Narrative and on each Sample Result Summary page.

Toluene was detected in the laboratory blank. Associated results were flagged as indicated.

Analytical Notes

Nine qualifiers may have been used on the data analysis sheets and indicates as follows: B - Compound present in laboratory blank greater than reporting limit (background subtraction not performed). J - Estimated value. E - Exceeds instrument calibration range. S - Saturated peak. Q - Exceeds quality control limits. U - Compound analyzed for but not detected above the reporting limit. UJ- Non-detected compound associated with low bias in the CCV N - The identification is based on presumptive evidence. C - Estimated concentration due to calculated sampling rate

LABORATORY NARRATIVEPassive SE GC/MS

Eurofins | mgt (formerly mgt Labmark Environmental Laboratories)Workorder# 1506322

Twenty WMS-SE samples were received on June 17, 2015. The laboratory extracted the charcoal sorbent bed of the passive sampler using carbon disulfide. An aliquot of the extract was injected into a GC/MS for identification and quantification of volatile organic compounds (VOCs).

The mass of each target compound adsorbed by the sampler was converted to units of concentration using the sample deployment time and the sampling rate for each VOC. If sampling rates were calculated by the lab or the manufacturer, the concentration result has been flagged as an estimated value. Results are notcorrected for desorption efficiency.

There were no receiving discrepancies.

Receiving Notes

If validated uptake rates were not available, rates were estimated by the vendor using the chemical's retention time on a nonpolar phase column. Chemicals that are poorly retained by the sorbent over the sampling duration may exhibit a low bias. All concentrations calculated using estimated rates are qualified with a "C" flag.

To calculate ug/m3 concentrations in the Lab Blank, a sampling duration of 9980 minutes was applied. The assumed temperature used for the uptake rate is listed on the data page. If the field temperatures were provided, the rate was adjusted in the same manner as the field samples.

All Quality Control Limit exceedances and affected sample results are noted by flags. Each flag is defined at the bottom of this Case Narrative and on each Sample Result Summary page.

Analytical Notes

Nine qualifiers may have been used on the data analysis sheets and indicates as follows: B - Compound present in laboratory blank greater than reporting limit (background subtraction not performed). J - Estimated value. E - Exceeds instrument calibration range. S - Saturated peak. Q - Exceeds quality control limits. U - Compound analyzed for but not detected above the reporting limit. UJ- Non-detected compound associated with low bias in the CCV N - The identification is based on presumptive evidence. C - Estimated concentration due to calculated sampling rate

File extensions may have been used on the data analysis sheets and indicates as follows: a-File was requantified

LABORATORY NARRATIVEPassive SE GC/MS

Eurofins | mgt (formerly mgt Labmark Environmental Laboratories)Workorder# 1506325

Eight WMS-SE samples were received on June 17, 2015. The laboratory extracted the charcoal sorbent bed of the passive sampler using carbon disulfide. An aliquot of the extract was injected into a GC/MS for identification and quantification of volatile organic compounds (VOCs).

The mass of each target compound adsorbed by the sampler was converted to units of concentration using the sample deployment time and the sampling rate for each VOC. If sampling rates were calculated by the lab or the manufacturer, the concentration result has been flagged as an estimated value. Results are notcorrected for desorption efficiency.

Sample collection date was not provided on the Chain of Custody (COC) for samples FB1 (15-702), FB2 (15-702) and FB3 (15-702). The sampling date was taken from the tag.

Receiving Notes

If validated uptake rates were not available, rates were estimated by the vendor using the chemical's retention time on a nonpolar phase column. Chemicals that are poorly retained by the sorbent over the sampling duration may exhibit a low bias. All concentrations calculated using estimated rates are qualified with a "C" flag.

To calculate ug/m3 concentrations in the Lab Blank and in the samples FB1 (15-702), FB2 (15-702) and FB3 (15-702) , a sampling duration of 9961 minutes was applied. The assumed temperature used for the uptake rate is listed on the data page. If the field temperatures were provided, the rate was adjusted in the same manner as the field samples.

All Quality Control Limit exceedances and affected sample results are noted by flags. Each flag is defined at the bottom of this Case Narrative and on each Sample Result Summary page.

The Relative Percent Difference (RPD) of the LCS/LCSD exceeded acceptance limits for Chloromethane.

Analytical Notes

Nine qualifiers may have been used on the data analysis sheets and indicates as follows: B - Compound present in laboratory blank greater than reporting limit (background subtraction not performed). J - Estimated value. E - Exceeds instrument calibration range. S - Saturated peak. Q - Exceeds quality control limits. U - Compound analyzed for but not detected above the reporting limit. UJ- Non-detected compound associated with low bias in the CCV N - The identification is based on presumptive evidence.

C - Estimated concentration due to calculated sampling rate

File extensions may have been used on the data analysis sheets and indicates as follows: a-File was requantified b-File was quantified by a second column and detector r1-File was requantified for the purpose of reissue
