This is the complete duplicate analysis of a sample from the process batch. If possible, the sample selected Duplicate should be one where the analyte concentration is easily measurable. A portion of the sample is spiked with a known concentration of target analyte. The purpose of the matrix spike Matrix Spike is to monitor the performance of the analytical method used and to determine whether matrix interferences Iexist. LCS (Laboratory This comprises either a standard reference material or a control matrix (such as a blank sand or water) fortified Control Sample) with analytes representative of the analyte class. It is simply a check sample. Surrogates are known additions to each sample, blank, matrix spike and LCS in a batch, of compounds which Surrogate Spike are similar to the analyte of interest, however are not expected to be found in real samples. Australian Drinking IWater Guidelines recommend that Thermotolerant Coliform, Faecal Enterococci, & E.Coli levels are less than 1cfu/100mL. The recommended maximums are taken from "Australian Drinking Water Guidelines", published by NHMRC & ARMC 2011. The recommended maximums for analytes in urine are taken from “2018 TLVs and BEIs”, as published by ACGIH (where available). Limit provided for Nickel is a precautionary guideline as per Position Paper prepared by AIOH Exposure Standards Committee, 2016. Guideline limits for Rinse Water Quality reported as per analytical requirements and specifications of AS 4187, Amdt 2 2019, Table 7.2 Laboratory Acceptance Criteria Duplicate sample and matrix spike recoveries may not be reported on smaller jobs, however, were analysed at a frequency to meet or exceed NEPM requirements. All samples are tested in batches of 20. The duplicate sample RPD and matrix spike recoveries for the batch were within the laboratory acceptance criteria. Filters, swabs, wipes, tubes and badges will not have duplicate data as the whole sample is generally extracted during sample extraction. Spikes for Physical and Aggregate Tests are not applicable. For VOCs in water samples, three vials are required for duplicate or spike analysis. Duplicates: >10xPQL - RPD acceptance criteria will vary depending on the analytes and the analytical techniques but is typically in the range 20%-50% – see ELN-P05 QA/QC tables for details; <10xPQL - RPD are higher as the results approach PQL and the estimated measurement uncertainty will statistically increase. Matrix Spikes, LCS and Surrogate recoveries: Generally 70-130% for inorganics/metals (not SPOCAS); 60-140% for organics/SPOCAS (+/-50% surrogates) and 10-140% for labile SVOCs (including labile surrogates), ultra trace organics and speciated phenols is acceptable. In circumstances where no duplicate and/or sample spike has been reported at 1 in 10 and/or 1 in 20 samples respectively, the sample volume submitted was insufficient in order to satisfy laboratory QA/QC protocols. When samples are received where certain analytes are outside of recommended technical holding times (THTs), the analysis has proceeded. Where analytes are on the verge of breaching THTs, every effort will be made to analyse within the THT or as soon as practicable. Where sampling dates are not provided, Envirolab are not in a position to comment on the validity of the analysis where recommended technical holding times may have been breached. Measurement Uncertainty estimates are available for most tests upon request. Analysis of aqueous samples typically involves the extraction/digestion and/or analysis of the liquid phase only (i.e. NOT any settled sediment phase but inclusive of suspended particles if present), unless stipulated on the Envirolab COC and/or by correspondence. Notable exceptions include certain Physical Tests (pH/EC/BOD/COD/Apparent Colour etc.), Solids testing, total recoverable metals and PFAS where solids are included by default. Samples for Microbiological analysis (not Amoeba forms) received outside of the 2-8°C temperature range do not meet the ideal cooling conditions as stated in AS2031-2012.

VOC/BTEX: PQL has been raised for sample 1, 2, 7, 8 and 11 due to the high concentration of analytes in the sample/s, resulting in the sample/s requiring dilution. METALS: # Percent recovery is not possible to report due to the high concentration of Boron and Manganese in the sample/s. However an acceptable recovery was obtained for the LCS. The PQL has been raised for Cadmium, Chromium, Copper and Tin due to the sample matrix requiring dilution. # Percent recovery is not possible to report due to the high concentration of Calcium, Sodium and Sulphur in the sample/s. However an acceptable recovery was obtained for the LCS.

Laboratory QC results for Method Blanks, Duplicates, Matrix Spikes, and Laboratory Control Samples follows guidelines delineated in the National Environment Protection (Assessment of Site Contamination) Measure 1999, as amended May 2013 and are included in this QC report where applicable. Additional QC data may be available on request. 2. All soil/sediment/solid results are reported on a dry basis, unless otherwise stated. 3. All biota/food results are reported on a wet weight basis on the edible portion, unless otherwise stated. 4. Actual LORs are matrix dependant. Quoted LORs may be raised where sample extracts are diluted due to interferences. 5. Results are uncorrected for matrix spikes or surrogate recoveries except for PFAS compounds. 6. SVOC analysis on waters are performed on homogenised, unfiltered samples, unless noted otherwise. 7. Samples were analysed on an 'as received' basis. 8. Information identified on this report with blue colour, indicates data provided by customer, that may have an impact on the results. 9. This report replaces any interim results previously issued. Holding Times Please refer to 'Sample Preservation and Container Guide' for holding times (QS3001). For samples received on the last day of holding time, notification of testing requirements should have been received at least 6 hours prior to sample receipt deadlines as stated on the SRA. If the Laboratory did not receive the information in the required timeframe, and regardless of any other integrity issues, suitably qualified results may still be reported. Holding times apply from the date of sampling, therefore compliance to these may be outside the laboratory's control. For VOCs containing vinyl chloride, styrene and 2-chloroethyl vinyl ether the holding time is 7 days however for all other VOCs such as BTEX or C6-10 TRH then the holding time is 14 days. **NOTE: pH duplicates are reported as a range NOT as RPD Units mg/kg: milligrams per kilogram mg/L: milligrams per litre ug/L: micrograms per litre ppm: Parts per million ppb: Parts per billion %: Percentage org/100mL: Organisms per 100 millilitres NTU: Nephelometric Turbidity Units MPN/100mL: Most Probable Number of organisms per 100 millilitres Terms Dry Where a moisture has been determined on a solid sample the result is expressed on a dry basis. LOR Limit of Reporting. SPIKE Addition of the analyte to the sample and reported as percentage recovery. RPD Relative Percent Difference between two Duplicate pieces of analysis. LCS Laboratory Control Sample - reported as percent recovery. CRM Certified Reference Material - reported as percent recovery. Method Blank In the case of solid samples these are performed on laboratory certified clean sands and in the case of water samples these are performed on de-ionised water. Surr - Surrogate The addition of a like compound to the analyte target and reported as percentage recovery. Duplicate A second piece of analysis from the same sample and reported in the same units as the result to show comparison. USEPA United States Environmental Protection Agency APHA American Public Health Association TCLP Toxicity Characteristic Leaching Procedure COC Chain of Custody SRA Sample Receipt Advice QSM US Department of Defense Quality Systems Manual Version 5.3 CP Client Parent - QC was performed on samples pertaining to this report NCP Non-Client Parent - QC performed on samples not pertaining to this report, QC is representative of the sequence or batch that client samples were analysed within. TEQ Toxic Equivalency Quotient QC - Acceptance Criteria RPD Duplicates: Global RPD Duplicates Acceptance Criteria is 30% however the following acceptance guidelines are equally applicable: Results <10 times the LOR : No Limit Results between 10-20 times the LOR : RPD must lie between 0-50% Results >20 times the LOR : RPD must lie between 0-30% Surrogate Recoveries: Recoveries must lie between 20-130% Phenols & 50-150% PFASs PFAS field samples that contain surrogate recoveries in excess of the QC limit designated in QSM 5.3 where no positive PFAS results have been reported have been reviewed and no data was affected. WA DWER (n=10): PFBA, PFPeA, PFHxA, PFHpA, PFOA, PFBS, PFHxS, PFOS, 6:2 FTSA, 8:2 FTSA QC Data General Comments 1. Where a result is reported as a less than (<), higher than the nominated LOR, this is due to either matrix interference, extract dilution required due to interferences or contaminant levels within the sample, high moisture content or insufficient sample provided. 2. Duplicate data shown within this report that states the word "BATCH" is a Batch Duplicate from outside of your sample batch, but within the laboratory sample batch at a 1:10 ratio. The Parent and Duplicate data shown is not data from your samples. 3. Organochlorine Pesticide analysis - where reporting LCS data, Toxaphene & Chlordane are not added to the LCS. 4. Organochlorine Pesticide analysis - where reporting Spike data, Toxaphene is not added to the Spike. 5. Total Recoverable Hydrocarbons - where reporting Spike & LCS data, a single spike of commercial Hydrocarbon products in the range of C12-C30 is added and it's Total Recovery is reported in the C10-C14 cell of the Report. 6. pH and Free Chlorine analysed in the laboratory - Analysis on this test must begin within 30 minutes of sampling.Therefore laboratory analysis is unlikely to be completed within holding time. Analysis will begin as soon as possible after sample receipt. 7. Recovery Data (Spikes & Surrogates) - where chromatographic interference does not allow the determination of Recovery the term "INT" appears against that analyte. 8. Polychlorinated Biphenyls are spiked only using Aroclor 1260 in Matrix Spikes and LCS. 9. For Matrix Spikes and LCS results a dash " -" in the report means that the specific analyte was not added to the QC sample. 10. Duplicate RPDs are calculated from raw analytical data thus it is possible to have two sets of data.

The naphthalene value used in this calculation is obtained from volatiles N01 (Purge & Trap analysis). Where we have reported both volatile (P&T GCMS) and semivolatile (GCMS) naphthalene data, results may not be identical. Provided correct sample handling protocols have been followed, any observed differences in results are likely to be due to procedural differences within each methodology. Results determined by both techniques have passed N02 all QAQC acceptance criteria, and are entirely technically valid. F1 is determined by arithmetically subtracting the "Total BTEX" value from the "C6-C10" value. The "Total BTEX" value is obtained by summing the concentrations of BTEX N04 analytes. The "C6-C10" value is obtained by quantitating against a standard of mixed aromatic/aliphatic analytes. Please note:- These two PAH isomers closely co-elute using the most contemporary analytical methods and both the reported concentration (and the TEQ) apply specifically to N07 the total of the two co-eluting PAHs The matrix spike recovery is outside of the recommended acceptance criteria. An acceptable recovery was obtained for the laboratory control sample indicating a sample matrix Q08 interference.

AECOM Delivered. Analytical Data Validation Introduction Analytical data validation is the process of assessing if data are in compliance with method requirements and project specifications. The primary objectives of this process are to ensure that data of known quality are reported, and to identify if the data can be used to fulfil the overall project objectives. The data validation guidelines that are adopted provide a consistent approach for the evaluation of analytical data. These guidelines are based upon the following data validation guidance documents: • USEPA Contract Laboratory Program National Functional Guidelines for Superfund Organic Methods Data Review, EPA-540-R-08-01, June 2008 • USEPA Contract Laboratory Program National Functional Guidelines for Inorganic Data Review, OSWER 9240.1-45, EPA 540-R-04-004, October 2004 • National Environment Protection Council (NEPC). 1999. National Environment Protection (Assessment of Site Contamination) Measure. Schedule B3. December. • Australian Standard AS4482.1, Guide to the investigation and sampling of sites with potentially contaminated soil – Part1: Non-volatile and semi-volatile compounds. A range of quality control tests are conducted and reported by the analytical laboratories to enable an assessment of the accuracy, precision and reliability of the project analytical data generated. Accuracy and precision can be defined as follows: accuracy - the degree of agreement of a measurement (or an average of measurements) with the accepted reference or true value. Analytical accuracy is analyte and matrix dependent. precision - the degree to which data generated from replicate or repetitive measurements differ from one another. Specific elements of data validation that will be checked and assessed for this project include: • preservation and storage of samples upon collection, processing and during transport to the laboratory; • use of NATA Accredited laboratory methods • sample holding times; • required limits of reporting; • frequency of conducting quality control measurements; • field and trip blanks; • laboratory blanks; • field duplicates; • laboratory duplicates; • matrix spikes • laboratory control sample spikes • surrogates; and • the occurrence of apparently unusual or anomalous results, eg. laboratory results that appear to be inconsistent with field observations or measurements. The specific methods used to check compliance and to assess accuracy, precision and useability of analytical data for this project are as follows: 1 of 4 Imagine it. AECOM Delivered. Sample Preservation, Storage, and Holding Time Requirements Sample preservation, storage temperature and holding time requirements are assessed in relation to guidelines recommended by the US EPA and/or APHA (American Public Health Association). If non-compliance to these requirements is observed for a given sample or samples, professional judgement is used to evaluate the extent to which sample integrity and hence sample results may have been compromised. NATA Accreditation Checks are made to ensure that all laboratory methods relied upon for interpretive use are National Association of Testing Authorities (NATA) accredited. Reporting Limit Requirements Checks are made to ensure that the laboratory has complied with project reporting requirements and specifically that laboratory limits of reporting are below the adopted assessment criteria. Blanks Blank samples are designed to monitor the introduction of artefacts or interferences into the sampling and analysis programs, which may lead to the reporting of false positive data. Field blanks (Rinsate Blanks) are samples of water from a known or controlled source (that ideally do not contain project analytes) prepared by sampling personnel in the same manner as regular samples. The associated sampling equipment is rinsed with this water at the completion of decontamination. The rinsate is collected directly into the same types of containers used for regular samples. The collection of field blanks enables the measurement of incidental or accidental contamination during the whole process (sampling, transport, sample preparation and analysis). Rinsate blanks are generally not collected where separate, dedicated sampling equipment is used at each sampling location. Trip blanks are employed where volatiles organic compounds (VOCs) are included in the analyte list. They comprise VOC-free samples of the appropriate media, stored in containers similar to those used for sample storage. The trip blanks are stored in the same locations (eg. ice chests) and accompany the samples from the field, ultimately to the laboratory. They will not, however, opened prior to receipt by the laboratory. Trip blanks are analysed as per the other samples and provide an indication of the occurrence of contamination during storage and shipment of samples. Laboratory blanks consist of reagents specific to each individual analytical method prepared and analysed by the laboratory in the same manner as regular samples. The preparation and analysis of laboratory blanks enables the measurement of incidental or accidental contamination within the laboratory. Field Duplicates Field duplicate samples are prepared in the field by splitting a field sample, then submitting them to the same laboratory as two independently labelled samples. Field duplicates are used to assess the precision of the whole process (sampling, sample preparation and analysis). However, discretion will be used when assessing the results of field duplicate data. In some cases (particularly with heterogeneous/fill material) influences other than sampling/laboratory precision can influence the results. In some cases the results of field duplicates can be used to assess the degree to which the particulate nature of the contaminant (or parameter) is effecting the overall data set. The relative percent difference (RPD) of each field duplicate set is calculated to assess overall precision, where: RPD = (C1 - C2) x 100% (C1 + C2)/2 where C1 = field sample measurement C2 = field sample duplicate Significant variation in field duplicate results is often observed (particularly for solid matrix samples) due to sample heterogeneity, and where reported results are less than ten times the laboratory limit of reporting. Professional judgement will be exercised when assessing field duplicate data. 2 of 4 Imagine it. AECOM Delivered. A field duplicate RPD value of <30% is generally considered acceptable, while RPDs <50% may be acceptable where concentrations are low (< 20 times the LOR). Where results are close to the LOR, elevated RPDs may be high, even where absolute differences are low and effectively negligible. Those RPDs that exceed these values will be considered on a case-by-case basis using professional judgement. It is noted that, in accordance with US EPA CLP guidance1 , where a duplicate sample RPD does not meet the criteria, consideration of the significance of the exceedance should be applied to all samples and analytes of the same matrix and analytical technique. Inter-laboratory Duplicate Samples (Triplicate or Split Samples) Split samples are samples prepared by mixing and splitting one large sample into two portions. One of these samples is submitted to the primary analytical laboratory, while the remaining sample is submitted to a secondary laboratory for the identical suite of analyses. Split samples are prepared and analysed in order to check the accuracy of data generated by the primary laboratory. Significant variation in split sample results is often observed due to sample heterogeneity and/or differences in analytical techniques employed by the laboratories involved. RPDs are assessed as per field duplicates. Laboratory Duplicates Laboratory duplicates are samples prepared within the laboratory by dividing a field sample into two portions and analysing separately. The analysis of laboratory replicate samples provides an indication of analytical precision and is also influenced by sample heterogeneity. The laboratory duplicate RPD is used to assess laboratory precision. A laboratory duplicate RPD of <30% is generally considered acceptable. Matrix Spike and Laboratory Control Sample Spikes/Spike Duplicates Matrix spikes (MS) are samples prepared within the laboratory by spiking the field sample with a known concentrations of specific analytes. Laboratory control sample pike/spike duplicates (LCS) are similarly prepared, by spiking a clean laboratory or contaminant free sample (blank). The results of the MS are used to assess the effects of the sample matrix on the accuracy of the analyses. The laboratory control sample spike (LCS) and spike duplicate (LCSD) are similarly analysed separately to assess the precision and accuracy of the analysis independent of the matrix analysed. Precision will be assessed by calculating the relative percent difference of the two results, whilst accuracy will be assessed by calculation of percent recovery, where: percent recovery (PR) = X/T x 100%, where X = the observed value of measurement T = "true" value Ideally, all calculated recoveries should be between 70-130%. The evaluation of these results is not necessarily straightforward, since the sample itself may produce effects due to such factors as the presence of sample interferences and high concentrations of analytes. Similarly the evaluation of blank spikes and spike duplicates is not necessarily straight forward, since the recoveries are not dependant on the matrices of the samples. Since these effects are outside the control of the laboratory, evaluation is often subjective and requires a considerable input of professional judgement. In addition, MS and LCS/LCSD data is evaluated in conjunction with other QC criteria, rather than an isolated assessment. Surrogates Surrogates (or system monitoring compounds) are used to assess the performance of individual organic analyses that involve chromatographic techniques. These compounds are spiked into all sample aliquots at the commencement of sample preparation. The spiked sample aliquots then undergo normal extraction and analysis procedures. Percent recoveries are calculated for each surrogate, providing an indication of analytical accuracy. Surrogate spiking is normally viable for gas chromatography/mass spectrometry (GC/MS) techniques only. Surrogate compounds are generally chosen to be representative of the analytical compounds under investigation, while not being present naturally themselves. This can mean that they are deuterated, alkylated or halogenated analogues, or structural isomers of the compounds under investigation. 1 US EPA Contract Laboratory Program, data review guidelines, https://www.epa.gov/sites/production/files/2017- 01/documents/national_functional_guidelines_for_inorganic_superfund_methods_data_review_01302017.pdf 3 of 4 Imagine it. AECOM Delivered. Surrogate percent recoveries between of 70-130% are generally considered acceptable. However, as with MS/MSDs, the evaluation of these results is not necessarily straightforward, since the sample itself may produce effects due to such factors as the presence of interferences and high concentrations of analytes. Since these effects are outside the control of the laboratory, evaluation is often subjective and requires a considerable input of professional judgement. Unusual or anomalous results Checks are made on the data set to identify any apparently unusual or anomalous results that appear inconsistent with field data or observations, are inconsistent with historical or other spatial data. Where any anomalies are identified, they are noted and professional judgement is used to assess their significance with regard to interpretive use of the data.

However, this is assessed to not change the risk profile of the sample. - Elevated RPDs should be taken into consideration when using data for TRH C6-C10, F1 and chloroform quantitatively. - Elevated RPDs should be taken into consideration when interpreting data for cis-1,2- dichloroethene, trichloroethene and tetrachloroethene where close to guidelines.

A:COM Delivered. Comments 1. Frequency of field QC The inter-laboratory duplicate sample was analysed only for key COPC, as per project specifications. The precision of the data can be assessed as acceptable based on the intra-laboratory duplicate RPDs, which were reported within control limits. 2. Canister pressure Final Canister Pressure Due to slight differences in canister flow rates between the primary, intra- laboratory duplicate and inter-laboratory duplicate samples, sampling was halted with residual vacuums higher than target (nominally -5 “Hg) in the following primary sample canister: - SV01 (-7.5 “Hg) Higher residual vacuums result in increases in laboratory limits of reporting due to dilution in the laboratory, but do not affect reported concentrations. As resultant LORs for SV01 were below adopted guidelines, this is not considered to affect interpretation of the reported results. Laboratory Receipt Canister Pressure The relative vacuum loss for canister samples were below 10%, suggesting no material leaks during transit to the laboratory, except for canister SV09. SV09 reported potentially material (approximately 11%) vacuum reductions (relative to collected volumes) during transit. The sample is considered to potentially be biased low by approximately 11% and this should be taken into consideration when interpreting the data. All results other than for cis-1,2-dichloroethene were well below guideline values. The concentration of cis-1,2-dichloroethene at SV09 exceeded the residential HIL but was well below the commercial/industrial HIL. An 11% increase in results against guidelines would not equate to any changes in the risk profile and therefore is not considered to affect the interpretation of results. 3. Field inter-laboratory Field inter-laboratory RPDs were reported within control limits, with the exception RPDs of TRH C6-C10 and F1 fractions, cis-1,2-dichloroethene, trichloroethene, tetrachloroethene and chloroform (as shown in the RPD table). As there are no adopted guideline values for TRH C6-C10 and chloroform, the elevated RPDs are not expected to affect interpretation of results against guidelines. However, the elevated RPDs should be taken into consideration when using the data quantitatively. As all concentrations of F1 were reported well below the adopted guidelines, the elevated RPD is not considered to affect the interpretation of results against guidelines. However, the elevated RPD should be taken into consideration when using the data quantitatively. This apparent lack of precision should be taken into consideration when interpreting concentrations of cis-1,2-dichloroethene, trichloroethene and tetrachloroethene close to guidelines. 4. Other comments Eurofins reported the following comment: · Naphthalene elutes outside the >C10-C12 range on the system used for sample analysis. As a result, >C10-C12 TRH value is equivalent to the modified F2 value. 2 of 2 r,· c:11 !~:·, Client Name: South Australia Environment Protection Authority A:COM >1·_:,"·· ··:i Project Name: Ethelton Stage 1 Environmental Assessment Project No: 60647266 Soil Vapour Leak Testing Isopropanol Leak Testing (Hood Vacuum Line Test Helium Leak Testing Canister Pressure Concentration 21,330,000 µg/m³ in Cleanliness QC03) Location ID Field ID Canister ID Regulator ID Lab Batch Sample Type Sample Date Certificate Final Stabilised Helium Initial Helium Final Helium Helium in Sampling Laboratory Initial Initial Canister Final Canister Relative Vacuum Isopropanol in Well/Hood Relative Vacuum at 1 Concentration in Concentration in Concentration in Line/Helium in Receipt Pressure Vacuum Pressure ("Hg) Pressure ("Hg) Loss (%) Canister µg/m3 % min Sampling Line (ppm) Chamber (%) Chamber (%) Chamber (%) ("Hg) SV01_22/12/2020 1L0134 167 ü 765575 Primary 22/12/2020 -30 -7.5 -5.9 7 <490 0.002% SV01 QC01_22/12/2020 1L0004 070 ü 765575 Intra lab dup 22/12/2020 -20 -20 0 62 31 0 -30 -5.5 -6.6 N/A <501 0.002% QC02_22/12/2020 3534 1814 ü 258822 Inter lab dup 22/12/2020 -29 -3.5 -4.0 N/A <240 0.001% SV02 SV02_22/12/2020 1L0054 203 ü 765575 Primary 22/12/2020 -18 -18 0 59 27 0 -30 -5 -5.0 0 <117 0.001% SV03 SV03_22/12/2020 1L0205 115 ü 765575 Primary 22/12/2020 -21 -21 0 68 36 0 -30 -5 -4.2 3 <114 0.001% SV04 SV04_22/12/2020 1L0031 076 ü 765575 Primary 22/12/2020 -22 -22 0 70 67 0 -30 -5 -5.7 N/A <121 0.001% SV05 SV05_22/12/2020 1L0213 194 ü 765575 Primary 22/12/2020 -23 -23 0 71 55 0 -30 -5 -5.3 N/A <119 0.001% SV06 SV06_22/12/2020 1L0015 1708 ü 765575 Primary 22/12/2020 -22 -22 0 65 53 0 -28 -5 -2.8 9.6 <108 0.001% SV07 SV07_22/12/2020 1L0219 1703 ü 765575 Primary 22/12/2020 -21 -21 0 72 57 0 -30 -5 -6.2 N/A <123 0.001% SV08 SV08_22/12/2020 1L0044 1703 ü 765575 Primary 22/12/2020 -23 -22.5 0 63 51 0 -30 -5 -4.5 2 <115 0.001% SV09 SV09_22/12/2020 1L0146 1708 ü 765575 Primary 22/12/2020 -23 -23 0 75 55 0 -30 -5 -2.3 10.8 <106 0.001% SV10 SV10_22/12/2020 1L0014 1703 ü 765575 Primary 22/12/2020 -22 -22 0 58 21 0 -30 -5 -5.9 N/A <122 0.001% - QC03_22/12/2020 1L0048 144 ü 765575 Isopropanol blank 22/12/2020 N/A N/A N/A N/A N/A N/A -30 -5 -4.4 2 21,330,000 N/A Leak Testing Revision 1 14 January 2021 Page 1 of 4 P:\606X\60647266\400_Technical\440_Field_and_laboratory_data\Dval\FINAL_SV DVAL Tables.xlsx Print Date: 21/01/2021 Imagine it.

A:COM Delivered. Comments 1. Frequency of field Field intra- and inter-laboratory duplicate samples were collected at a frequency QA/QC of one in twenty primary samples (one of each in total). Due to discrepancies in standard analytical suites between the primary and secondary laboratories, inter- laboratory duplicate samples were not analysed for: · 1,1-dichloropropene · 1,2,3-trichlorobenzene · 1,2,4-trichlorobenzene · 1,2-dibromo-3-chloropropane · 2,2-dichloropropane · 2-chlorotoluene · hexachlorobutadiene · n-propylbenzene · n-butylbenzene · sec-butylbenzene · cyclohexane · tert-butylbenzene · p-isopropyltoluene · dibromofluoromethane · dibromofluoromethane · hydroxide alkalinity · total alkalinity · hardness and · phosphate (as P) The precision of the data can be assessed as acceptable based on the intra- laboratory duplicate RPDs and available laboratory duplicate RPDs which were within control limits 2. Sample handling/ Handling/preservation preservation/ holding Sample receipt temperature (13.4°C) was outside of the recommended range times (≤6°C) in primary batch 24174. The inter-laboratory sample was received at the secondary laboratory at an elevated temperature (24.9°C). It was noted by the primary laboratory (Envirolab) that an attempt to chill the samples was evident, and the ambient temperature on the day of sampling and transport to the primary laboratory was over 40°C. It was also noted that the ambient temperature was over 40°C on the day the inter-laboratory duplicate samples were transported to the secondary laboratory (Eurofins). All samples were immediately stored in a fridge upon arrival to the laboratories. Volatile analytes have the potential to be under reported, however the field intra- and inter-laboratory duplicate RPDs were within control limits for all volatile organic compounds, despite the difference in sample receipt temperature (between the primary and secondary laboratory). There were no concentrations of volatile analytes in the trip blank sample, indicating that cross contamination via volatilisation did not occur. Transport times were minimised between collection of the samples, receival of samples and extraction/analysis of samples (short turnaround time). AECOM considers that given volatilisation is a rate dependent process and that the exposure period of samples to higher temperatures would have been minimal, these elevated sample receipt temperatures are unlikely to affect the interpretation of results. 2 of 5 2 of 5 1~1ne1t. ,._._v,n•~u.··· Oellvefed 3.Frequency of Laboratory duplicate samples were not reported at the required frequencies for Laboratory QA/QC volatile organic compounds in water, volatile and semi-volatile TRH and metals, as per the frequency table. The precision of the data can be assessed as acceptable based on the intra- and where available the inter-laboratory duplicate RPDs, which were generally reported and within control limits. Matrix spikes and laboratory control spikes were not reported for the following analytes: · 1,1,1,2-tetrachloroethane · 1,1,2,2-tetrachloroethane · 1,1,2-trichloroethane · 1,1-dichloroethene · 1,1-dichloropropene · 1,2,3-trichlorobenzene · 1,2,3-trichloropropane · 1,2,4-trichlorobenzene · 1,2-dibromo-3-chloropropane · 1,2-dichloropropane · 1,3-dichlorobenzene · 1,3-dichloropropane · 1,4-dichlorobenzene · 2,2-dichloropropane · 2-chlorotoluene · 4-chlorotoluene · benzene · bromobenzene · bromoform · bromomethane · carbon Tetrachloride · chlorobenzene · chloroethane · chloromethane · cis-1,2-dichloroethene · cis-1,3-dichloropropene · dibromomethane · ethylbenzene · hexachlorobutadiene · toluene · trans-1,2-dichloroethene · trans-1,3-dichloropropene · styrene · 1,3,5-trimethylbenzene · bromochloromethane · isopropylbenzene · n-propylbenzene · n-butylbenzene · sec-butylbenzene · cyclohexane · tert-butylbenzene · p-isopropyltoluene · vinyl chloride · 1,2-dichlorobenzene · 1,2,4-trimethylbenzene · m&p-xylene · o-xylene · 1,2-dibromoethane (EDB) · trichlorofluoromethane (Freon 11) · dichlorodifluoromethane (Freon 12) 3 of 5 3 of 5 1~1ne1t. ,._._v,n•~u.··· Oellvefed The following were not reported for matrix spikes only: · hexavalent chromium · methane · ethane · ethene · fluoride · nitrite (as N) · ammonia · phosphate · chloride and · sulfate The accuracy of the data can be assessed as acceptable based on method blanks and surrogate spike recoveries (where available), as well as available matrix spike and LCS recoveries for the same method group (which were reported at or above the required frequencies and within control limits). 4.Limits of reporting Limits of reporting were sufficiently low to enable assessment against adopted guideline criteria, with the exception of 1,2-dichloroethane, 1,4-dichlorobenzene, bromomethane, carbon tetrachloride, hexachlorobutadiene, naphthalene, styrene, vinyl chloride, 1,2-dichlorobenzene, benzene, ethylbenzene, silver, copper and hexavalent chromium. The potential exists for concentrations of key COPC benzene, ethylbenzene, styrene, 1,2-dichlorobenzene, 1,4-dichlorobenzene, vinyl chloride, bromomethane, carbon tetrachloride, 1,2-dichloroethane, hexachlorobutadiene, silver, copper and hexavalent chromium to be above the adopted guidelines, but below the laboratory LOR. This should be taken into consideration when interpreting data and using data quantitatively. The potential exists for naphthalene in QC201 to be above the adopted guidelines, but below the laboratory LOR. As the primary (MW01) and intra- laboratory duplicate (QC101) samples reported all concentrations below the laboratory LOR and the adopted guidelines, this is not expected to affect the interpretation of results against guidelines. 5.Rinsate blank A total of two rinsate blank samples were obtained from the pump and interface probe and were analysed for the one day of sampling. All concentrations of analytes were below LOR, with the following exceptions: · QC301 (pump): Sulfate at 32 mg/L Ammonia at 0.019 mg/L · QC302 (interface probe): Nitrate at 0.015 mg/L NOx (nutrients in water) at 0.015 mg/L The above concentrations of sulfate above the LOR (1 mg/L), ammonia (LOR 0.05 mg/L), Nitrate (LOR 0.05 mg/L) and NOx (LOR 0.05 mg/L) indicate the potential for a small degree of nutrient cross contamination introduced into the samples from the pump and interface probe. However, a number of samples reported below the LOR for Nitrate and NOx, so this does not appear to be a systematic error associated with decontamination procedures. The detected concentrations of sulfate, ammonia, nitrate and NOx in the rinsate samples are well below guideline values and would not add to the contaminant load in a way that would change the risk profile of individual samples. 4 of 5 4 of 5 1~1ne1t. ,._._v,n•~u.··· Oellvefed 6. Field intra-laboratory Field intra-laboratory duplicate RPDs were reported within control limits, with the duplicate RPDs exception of ammonia (33%) (as shown in the RPD table). This apparent lack of precision should be taken into consideration when interpreting concentrations for ammonia close to guidelines. 7. Field inter-laboratory Field inter-laboratory RPDs were reported within control limits, with the exception duplicate RPDs of molybdenum (34%), calcium (56%), magnesium (30%) and nitrate (67%) (as shown in the RPD table). As there are no adopted guideline values for magnesium, the elevated RPD will not affect interpretation of results against guidelines. However, the elevated RPD should be taken into consideration when using the data quantitatively. As all concentrations of nitrate were reported well above or well below the adopted guidelines, the elevated RPD is not considered to affect the interpretation of results against guidelines. However, the elevated RPD should be taken into consideration when using the data quantitatively. This apparent lack of precision should be taken into consideration when interpreting concentrations for molybdenum and calcium close to guidelines. 8. MS % recoveries Matrix spike recoveries (where reported) were within control limits. Envirolab laboratory noted that matrix spike recoveries were not possible to report for boron due to the high concentration of boron and manganese in the samples. Matrix spike recoveries were also not possible to report for calcium and sodium due to the high concentration of calcium, sodium and sulphur in the samples. These non-determinations do not reflect method bias and do not affect data interpretation. The accuracy of the data can be assessed as acceptable based on method blanks and LCS recoveries (which were reported at the required frequencies and within control limits). 9. Other comments General Comments Envirolab laboratory noted the following: · VOC/BTEX: LOR has been raised for sample GW01, GW01_S, GW05, GW06 and GW06 due to the high concentration of analytes in the samples, resulting in the sample/s requiring dilution. · The LOR has been raised for cadmium, chromium, copper and tin due to the sample matrix requiring dilution. 5 of 5 5 of 5 A.=r',01.1.1 1_-:,:·:1 Client Name: South Australia Environment Protection Authority l"l.iiiii'-' ffl 1,.· ', ....

The Environment Protection (Water Quality) Policy 2015 (WQEPP (2015)) provides detail to support the EP Act and provides the structure for regulation and management of water quality in South Australian inland surface waters, marine waters and groundwaters. The WQEPP (2015), which came into force on 1 January 2016, also provides information on: • what constitutes environmental harm (section 5 in the Act) • what are the general environmental duty requirements (section 25 in the Act) • what are the mandatory provisions which constitute offences (section 34 in the Act). and, with regard to the selection of analytical screening criteria, it: • declares default environmental values for the protection of streams, rivers, oceans and groundwater; and • provides references to national guidance documents for the identification of relevant analyte or chemical guideline values, referred to in the EPP (2015) as Trigger Values. In July 2018, the South Australian Environment Protection Authority (SA EPA) issued its updated Guidelines for the assessment and remediation of site contamination (GAR), which describes the legislative and policy approach to risk-based assessment and remediation of site contamination, and supports the objects of the EP Act. The update of the GAR has aligned the regulatory requirements with the risk-based approach to groundwater assessment, such that the process of selection of health and ecological groundwater screening levels is now consistent for both purposes. It is noted that South Australian legislation (Section 83A of the EP Act) includes a mandatory requirement for notification of the SA EPA in the event of identification of site contamination that affects or threatens groundwater. The GAR clarifies this requirement to apply when actual or potential harm to groundwater has been identified, or remediation is required to prevent harm to groundwater occurring. The notification is to be made as soon as reasonably practicable, and the obligation for notification falls on site owners, environmental consultants and Site Contamination Auditors. 1.2 Groundwater Assessment Criteria Reference Documents The primary reference for site contamination assessment in Australia is the National Environment Protection (Assessment of Site Contamination) Measure 1999 (ASC NEPM), which provides direction as to groundwater screening criteria for assessment of human health risk and ecological protection, drawn from other national guidance documents including the Australian Drinking Water Guidelines (NHMRC 2011) and the Australian and New Zealand Guidelines for Fresh and Marine Water Quality (ANZECC/ARMCANZ, 2000). The WQEPP (2015) refers to the same national guidance documents (as well as referencing the Guidelines for Managing Risks in Recreational Waters (NHMRC 2008) in stipulating guideline values for contaminants in waters. The SA EPA GAR (2018) details published criteria deemed as appropriate by the SA EPA for assessment of chemical impacts to groundwater, including determination of whether chemical impacts to groundwater represent ‘actual or potential harm’ and are ‘not trivial’ with respect to Section 5B(1)(c) of the EP Act. These referenced criteria are consistent with the approach outlined in the ASC NEPM and WQEPP; the process described in the GAR is adopted for derivation of screening levels for sites in South Australia. Under this process, determination of actual or potential harm to groundwater takes into account the applicable environmental values of groundwater, as outlined in the section below. P:\606X\60647266\400_Technical\430_Technical Working Documents\Report\Appendix P - Assessment Criteria\App P Groundwater Investigation Levels.docx Revision 1 – 04-Feb-2021 Prepared for – South Australian Environment Protection Authority – ABN: 85 393 411 003 AECOM Ethelton Assessment Area P-2 1.3 Selection of Assessment Criteria Selection of appropriate assessment criteria requires determination of the environmental values of groundwater at a site. Where multiple environmental values are identified, the most sensitive environmental value is applied. The process for determination of environmental values is documented in Figure 2 of the GAR, as reproduced below: Step 3: Review Step 4: Application of 1: ApplyTable3 Step 2: Assess and registered EPA recognised of Schedule 1 of the identify surface water groundwater users criteria for most WQEPP based on TDS bodies within 2km (WaterConnect sensitive range mg/L buffer area database) environmental value Step 1 – Determination of Groundwater Environmental Values from WQEPP The WQEPP (2015) presents the environmental values to be considered for groundwater based on the background total dissolved solids (TDS) concentration, as detailed in Table 1. The GAR notes that determination of salinity should be based on a combination of field measurements and laboratory analysis and selection of the most conservative salinity level. Table 1 Environmental Values of Underground Waters Primary Primary Industries – Primary Drinking water Industries – aquaculture Industries – Waters for human irrigation and and human livestock consumption general water consumption drinking water uses of aquatic foods Underground waters as follows a. Underground waters with a background TDS level X X X X of less than 1,200 mg/L b. Underground waters with a background TDS level X X X of 1,200 mg/L or more, but less than 3,000 mg/L c. Underground waters with a background TDS level X X of 3,000 mg/L or more, but less than 13,000 mg/L Step 2 – Relevant Environmental Values for Surface Water Interactions Consideration of environmental values of fresh and marine aquatic ecosystems and recreational (non- domestic) value are determined on the basis of the presence of surface water bodies within a 2 km buffer distance as prescribed by the GAR. Step 3 – Review of Groundwater Use from WaterConnect Database Review of available groundwater data by reference to the WaterConnect database of registered groundwater wells (maintained by the Department of Environment and Water) is used to determine groundwater environmental values within a 2 km buffer distance of the site. Environmental values are determined based on the recorded use of wells, with domestic (DOM) and town water supply (TWS) requiring consideration of Drinking Water environmental value, and Industrial (IND) and Irrigation (IRR) bores warranting consideration of appropriate environmental values also. It is noted that recorded salinity values in this database may contribute to the salinity assessment in Step 1.

The WQEPP (2015) references the Australian and New Zealand Guidelines for Fresh and Marine Water Quality 2000 prepared by ANZECC and ARMCANZ (ANZECC 2000). However, the ANZECC (2000) has been superseded by the Australian and New Zealand Guidelines (ANZG) for Fresh and Marine Water Quality 2018. It is therefore considered appropriate to apply the most current assessment criteria. The ANZG (2018) note that guidelines for aquaculture and human consumption of aquatic foods have not been revised since the ANZECC (2000) guidelines. ANZG (2018) further notes that most of these guideline values should be used with caution as few are based on a critical assessment of a wide dataset. ANZG (2018) further recommends that aquatic ecosystem guideline values be used as additional indicative information as they will generally be protective of aquaculture species.

Refer to section 6.5 of the ADWG 2011. ** Recommends application of a factor of 10 to 20 to the Australian Drinking Water Guidelines. *** ANZG 2018 recommends the aquatic ecosystem guideline values are protective of aquaculture species and should be applied for primary industry – aquaculture. 1.4 Application of Assessment Criteria It is noted that the GAR presents a risk-based framework for the assessment and management of site contamination of groundwater, such that it is the risk(s) associated with the harmed groundwater that will determine the need for remediation. Assessment of risks associated with groundwater contamination is conducted with reference to the framework set out in the ASC NEPM. Groundwater Investigation Levels The groundwater investigation levels determined through application of the process described above are concentrations of a contaminant in groundwater above which further investigation or response is warranted, and are applicable to assessing human health and ecological risk associated with direct contact (including consumption). Health Screening Levels (HSLs) for Vapour Intrusion While the ASC NEPM references and draws upon a number of the guidance documents referenced as trigger values by the EPP (2015) and recognised criteria by the GAR (2018), it also includes Health Screening Levels (HSLs) based on the vapour intrusion pathway from groundwater. These HSLs are P:\606X\60647266\400_Technical\430_Technical Working Documents\Report\Appendix P - Assessment Criteria\App P Groundwater Investigation Levels.docx Revision 1 – 04-Feb-2021 Prepared for – South Australian Environment Protection Authority – ABN: 85 393 411 003 AECOM Ethelton Assessment Area P-4 derived from those presented by CRC CARE in its September 2011 publication Health screening levels for petroleum hydrocarbons in soil and groundwater (Technical report no. 10). The groundwater HSLs for petroleum hydrocarbons were developed to be protective of human health in consideration of the vapour intrusion pathway; they do not take into account potential environmental risks or potential health risks due to direct contact with the groundwater. The NEPM presents groundwater HSLs for petroleum hydrocarbons (TRH fractions and BTEXN) for different land uses, groundwater depths and soil types. In order to validate use of the guidelines for comparison with groundwater contaminant concentrations on the site, an application checklist was completed to confirm the appropriateness of HSL application and any limitations that may need to be applied. While the HSL methodology allows for adjustment of the HSLs for site-specific conditions, for the purpose of a screening level assessment, the conservative unadjusted values are applied.
