1.0 INTRODUCTION Golder Associates (Golder) was commissioned by the City of Victor Harbor (Council) to conduct a groundwater, surface water and leachate monitoring event (GME) at the Victor Harbor Landfill (‘the site’), situated on Jagger Road, Waitpinga, South Australia. A site location plan is provided as Figure 1.

The works outlined in the proposal (Golder reference P19127795-001-P-Rev0) dated 25th July 2019 were based on relevant South Australian Environment Protection Authority (SA EPA) guidance documents and to comply with conditions of the site’s current EPA licence (License No. 359) provided in Appendix A. Details of the groundwater, surface water and leachate monitoring is also presented in the Landfill Environmental Management Plan (LEMP), an extract of which was provided to Golder.

1.1 Objectives This report documents groundwater, surface water and leachate monitoring conducted by Golder at the site in September 2019, in the context of previous monitoring programs undertaken at the site since 2004. The principal objectives of the monitoring event were to:

Complete sampling and laboratory analysis of groundwater from existing onsite wells in accordance with the EPA license and LEMP.

Assess for potential impacts to surface water and groundwater associated with the closed landfill.

1.2 Scope of Work The following scope of work was undertaken:

Obtain groundwater samples from all seven groundwater wells at the site;

Obtain leachate samples from the leachate collection tank at the toe of the landfill

Collect a sample of surface water from downstream of the toe of the landfill

Send all samples for laboratory testing of the analytes required by the LEMP; and

Review and provide a report which summarises the results against the relevant guidelines and historical data.

2.0 SITE SETTING 2.1 Site Location and Description The Victor Harbor Landfill is classified as a large landfill (South Australia EPA Guidelines for Environmental Management of Landfill Facilities-Solid Waste Disposal, 2019). The landfill is located in a valley approximately 6 km south west of Victor Harbor. A site location plan is presented as Figure 1. The landfill and surrounding land are zoned as general farming, with the nearest residential property located approximately 550 m southeast of the landfill. The site is approximately 33.8 ha in area and is assigned as Allotment 60, Deposited Plan 72974. An area of approximately 4.5 ha in the north portion of the site was historically used for landfilling (URS, 2015).

The landfill occupies a portion of an approximately east-west trending valley with an average gradient of approximately 1V:10H towards the east, and with sides of approximate gradient of 1V:2H. The sea is located approximately 650 m from the nearest site boundary. Survey data contained in the LEMP indicates that the ground elevation at the toe of the landfill (assumed to correspond to the original elevation of the valley floor) is approximately 50 mAHD.

The facility commenced operation in 1974 and comprised three main areas: a resource recovery and waste transfer facility, a green organics processing area, and the main landfill waste disposal area. A leachate interception system was constructed at the toe of the landfill in March 2011. The leachate interception system was designed to collect seepages at the landfill toe via a gravel filled interception trench for temporary storage in a tank adjacent to the toe, before pumping to an evaporation pond on the upper portion of the northern valley side. The City of Victor Harbor advised that all landfill operations ceased at the site on 1 October 2012, with capping being completed in 2013.

Annual monitoring of groundwater, surface water and leachate is required at site as outlined in the LEMP, and multiple assessment rounds have been historically conducted since 2004.

2.2 Geology and Hydrogeology The South Australian Geological Survey 1:100,000 Encounter geological sheet indicates that the surface geology of the site corresponds to the Balquhidder Formation, part of the Kanmantoo Group (Cambrian Age). The Balquhidder formation consists of primarily metasandstones and metasiltstones. The rock dip is steeply to the southeast and strikes to the northeast.

The Balquidder Formation metasediments constitute a fractured rock aquifer system, with hydraulic parameters expected to be variable according to fracture geometry and connectivity. The observed depth to groundwater at the site has varied between 0.3 m and 66 m depending on location within the valley. Some of these observations may represent perched groundwater rather than the regional water table. Previous monitoring rounds suggest that groundwater flow is towards the east-southeast, parallel with the alignment of the valley.

A report by Water Search (2004) indicates that cross-cutting quartz veining is common in the area and has been associated with mineralized zones. Such mineralisation may be reflected in the minor ion chemistry of the local groundwater, particularly in the possible presence of elevated concentrations of sulphate and heavy metals.

Surface water at the site is expected to flow along the topography of the valley to the east and southeast. Prior to the landfilling activities, springs are documented as having existed in the general area at the base and sides of the landfill (URS, 2015). Drainage channels along the flanks of the landfill and the installation of the leachate interception system at the toe of the landfill would have altered the surface water movements across the site.

3.2 Sampling Methodology 3.2.1 Groundwater Levels Groundwater levels were recorded in the monitoring wells (DH1, DH2, DH4, 65245, 65246 and 65247) on 12 September 2019. Water levels were measured using an electronic water level probe. The water level probe was rinsed with a Decon 90 solution and deionised water prior to the commencement of fieldwork and between sampling locations, to minimise the possibility of cross-contamination between bores.

3.2.2 Groundwater Sampling Groundwater samples were collected from the following monitoring wells (DH1, DH2, DH4, 65245, 65246, and 65247) on 12 September 2019.

Sampling from the four shallow groundwater monitoring wells (65245, DH1, DH2 and DH4) was undertaken using low-flow (micro-purge) method whereby a small volume of groundwater is slowly purged whilst maintaining a consistent drawdown. Groundwater field parameters including pH, dissolved oxygen (DO), electrical conductivity (EC), temperature, and redox potential were measured using a calibrated water quality

meter during low-flow purging. Once field parameters had stabilised a groundwater sample was collected. Field observations of the colour, turbidity and odour were also noted.

The two deeper monitoring wells 65246 and 65247 were sampled using disposable bailers. A small volume of groundwater was removed (~5 L) and field parameters measured prior to collection of a groundwater sample.

Field purge sheets recording the sampling methods and chemical parameters are included as Appendix B.

To minimise the potential for cross-contamination between bores during water level gauging and sampling, the interface probe and low-flow pump were cleaned with a Decon 90 solution and deionised water prior to the commencement of field work and between sampling locations. A new disposable bladder unit and dedicated tubing were used at each monitoring well. An equipment rinsate quality control sample (R01) was collected from the tubing used for purging and sampling the wells to confirm the absence of cross-contamination from sampling equipment. A trip blank quality control sample (TB01) was also submitted with the samples to the laboratory to confirm the absence of volatiles that may influence the samples during transport.

Six groundwater samples were collected, plus one intra-laboratory (blind) and one inter-laboratory (split) duplicate (from well 65245) and were placed into laboratory prepared bottles containing the appropriate preservatives. Samples analysed for dissolved metals were collected in the field using 0.45 micron filters. The samples were stored in cool boxes with ice bricks and dispatched to Australian Laboratory Services Pty Ltd (ALS), which is accredited by the National Association of Testing Authorities (NATA), under Golder chain of custody procedures.

3.2.3 Leachate and Surface Water Sampling A sample was collected from the leachate collection tank at the toe of the landfill (LT1), and a surface water sample (SW1) was collected east (down hydraulic gradient) of DH1 as shown in Figure 1. Field parameters were recorded at both locations. The samples were collected using an extendable swing sampler directly into laboratory supplied bottles and were sent to ALS. Surface water samples were analysed for total metals and therefore did not require filtering. The samples were transported to the analytical laboratory (ALS) in cool boxes with ice bricks under Golder chain of custody procedures.

3.4 Groundwater Assessment Screening Levels The Environment Protection Act 1993 (the EP Act) and the Environment Protection (Site Contamination) Regulations 2009 [the EP(SC) Regulations] set the regulatory framework for the investigation and management of contaminated land and water in South Australia. 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 SA EPA license and LEMP do not provide advice regarding the comparison of monitoring results to guideline levels or criteria. Previous monitoring undertaken at the site compared results to water quality levels presented in the now superseded Environment Protection (Water Quality) policy 2003, as well as the ASC NEPM groundwater investigation levels (GILs) and the WQEPP 2015.

In July 2018, the South Australian Environment Protection Authority (SA EPA) issued 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. Included in the GAR 2018 are the steps for determining the Environmental Values (as per WQEPP 2015) relevant for the site.

The 2018 Victor Harbor Landfill Groundwater, Leachate and Surface Water Monitoring Event report (AECOM 20181) included details regarding determination of the Environmental Values for groundwater and surface water at the site. A summary of the justification for the selected Environmental Values (as presented in AECOM 2018) and updated relevant information is provided below.

3.4.1 Local Groundwater Salinity and Use A groundwater bore search within a 2 km radius of the site was undertaken by Golder using the WaterConnect online groundwater database on 15 October 2019. The records are detailed in Appendix F, including the use and operational status of the 46 registered bores listed on the database.

Based on listed groundwater bore uses within a 2 km buffer distance of the site (Appendix F), the following registered groundwater uses were noted:

2 bores recording domestic use;

1 bore recording irrigation; and

8 bores for stock use.

Based on regional groundwater salinity (Appendix F), field measured salinity (as EC) (Appendix B) and laboratory TDS results (Appendix C), shallow groundwater was typically moderately saline (>2,500 mg/L).

3.4.2 Surface Water Interaction The following surface water bodies were identified within a 2 km buffer zone of the site:

Areas of intermittent ponded stormwater

Un-named and ephemeral creeks

Various farm dams (closest located 150 west of the site, downgradient closest dam was 350 m)

3.4.3 Applicable Environmental Values Based upon the summary above, the following Environmental Values were considered applicable for the site:

Recreation and aesthetics (primary and aesthetic);

Primary Industries (irrigation, livestock and aquaculture); and

Aquatic ecosystem protection (fresh / marine);

Groundwater assessment criteria appropriate to these Environmental Values and recognised by the SA EPA have been selected in accordance with the GAR. It is noted that these applicable groundwater environmental values derived under direction from the GAR and the exclusion of potable use criteria are generally consistent with those previously applied EPPWQ 2015 in the 2017 monitoring round (Golder, 2017) and consistent with the 2018 monitoring round (AECOM, 2018).

4.0 MONITORING RESULTS 4.1 Groundwater Elevations and Flow Groundwater level data was collected from six wells on 12 September 2019. Standing Water Levels (SWL) were measured in monitoring wells prior to sampling. The SWL measurements recorded in September 2019 are summarised in Table 4, along with groundwater elevations in Australian Height Datum (AHD) calculated from top of casing survey measurements presented in the AECOM 2018 report.

The groundwater elevations ranged from 93.011 m AHD at the inferred up-hydraulic gradient well 65245, to 23.162 m AHD at the inferred down-hydraulic gradient DH1 located at the toe of the landfill. The inferred groundwater flow direction is to the southeast, along the valley and towards the ocean. Groundwater elevations are shown on Figure 2 at the rear of this document.

Plot 3: Chloride Concentrations

4.3.2 Biological and Chemical Oxygen Demand Biological Oxygen Demand (BOD) is a measure of the biologically degradable organic matter in water and is determined by measuring the amount of oxygen that bacteria require to degrade the organic matter.

Observed BOD concentrations in groundwater samples collected during the 2019 monitoring round ranged from less than the laboratory LOR of 2 mg/L in 65245 and 65246 to 52 mg/L in DH2. BOD concentrations in DH2 exceeded the ANZECC Freshwater Aquaculture screening levels, consistent with historical results.

Chemical oxygen demand (COD) is a measure of the quantity of oxygen used in biological and nonbiological oxidation of materials in water. COD results ranged from 16 mg/L in 65245 to 140 mg/L in DH2. COD concentrations in all groundwater samples exceeded the ANZECC Freshwater Aquaculture screening levels except for 65245, 65246 and DH4, similar to the 2018 monitoring round results.

4.3.3 Total Organic Carbon Reported concentrations of total organic carbon (TOC) ranged from less than the laboratory LOR of 1 mg/L in DH4 to 34 mg/L in 65247. All wells reported concentrations of TOC within historical ranges. Consistent with historical results, no TOC concentrations exceeded the adopted screening levels.

4.3.4 Nutrients Total Phosphorus

Concentrations of total phosphorus observed in the 2019 monitoring round ranged 0.04 mg/L in 65246 to 1.43 mg/L in DH2. Plot 4 below shows observed phosphorous concentrations against time. All sample results exceeded the ANZECC Irrigation screening levels, with the exception of well 65246. All wells reported concentrations of phosphorous within historical ranges and the results for most wells appear to have decreased since the 2018 monitoring round.

Iron

Concentrations of total iron ranged from 2.68 mg/L in 65245 to 67.3 mg/L in DH2, exceeding the ANZECC Freshwater and Saltwater Aquaculture screening levels in all groundwater samples. Concentrations of iron also exceeded the ANZECC Irrigation screening levels in groundwater sampled from 65245, 65247, DH3, and DH4. Concentrations of iron in the groundwater samples have shown considerable fluctuation throughout the monitoring events. Iron concentrations are likely to be elevated as iron occurs naturally in the bedrock and the highest concentrations have historically been reported in background well 65245.

Mercury

Reported concentrations of mercury in all groundwater samples were reported below the LOR, consistent with historical results

Nickle

Concentrations of nickel ranged from 0.001 mg/L in 65245 and 65246 to 0.118 mg/L in DH1. The nickel concentration in the sample collected from DH1 exceeded the ANZECC Freshwater and Saltwater Aquaculture and ANZECC Maintenance of Freshwater and Marine Ecosystems screening levels. No other sample results exceeded the adopted screening levels. As shown in Plot 9 below, all reported results were within historical variation.

Zinc

Reported concentrations of zinc ranged from 0.007 mg/L in DH1 to 0.022 mg/L in 65247. Concentrations of zinc exceeded the ANZECC Freshwater and Saltwater Aquaculture and ANZECC Maintenance of Freshwater and Marine Ecosystems screening levels in groundwater sampled from all wells, with the exception of well 65246 which reported a concentration below the LOR. Concentrations of zinc were reported within historical ranges for all groundwater samples.

4.3.6 TRH and BTEXN Concentrations of TRH fractions were detected above the LOR in monitoring wells 65247, DH1, and DH2, and were consistent with historical results. Concentrations of TRH (C16-C34) (F3) were detected in collected sample from 65247, DH1 and DH2. Reported TRH concentrations did not exceed the NEPM 2013 Residential HSLs. TRH concentrations were below the LOR for all wells for both TRH F1 (C6-C10) and F2 (C10-C16) and consistent with historical results.

Silica gel clean-up and reanalysis was conducted on samples 65247, DH1 and DH2. A concentration of TRH (C16-C34) (F3) was detected in the sample from DH2 at 0.13 mg/L. However, concentrations have remained below the adopted assessment level, consistent with historical results.

BTEXN concentrations in all groundwater samples were below the LOR and below the adopted screening levels. In the 2018 monitoring round concentrations of toluene were detected in samples from 65246 and 65247.

4.3.7 Pesticides, PAH and Phenols Groundwater samples collected during this monitoring round were reported at concentrations below the laboratory LOR for all OC and OP pesticides, PAHs, and phenolic compounds, consistent with previous historical results.

4.4 Surface Water and Leachate Results Water samples were collected from the leachate collection tank at the toe of the landfill (LT1), west (up hydraulic gradient) of DH1 and surface water (SW1), east (down hydraulic gradient) of DH1. A summary of the results for surface and leachate are as follows:

Leachate sample:

▪ LT1 sample had concentrations of boron, iron, BOC, COD, nitrate, total kjeldahl nitrogen, total nitrogen, total phosphorus, and magnesium greater than of one or more adopted screening levels.

▪ These concentrations were consistent with the historical results.

▪ Concentrations of TPH (after silica gel clean-up) in LT1 were marginally above the LOR for TPH F3 fraction (>C15-C34).

Surface water sample:

▪ SW1 sample had concentrations boron, copper, iron, lead, nickel, zinc, BOD, COD, nitrite, total kjeldahl nitrogen, total nitrogen, total phosphorus, and magnesium greater than one or more adopted screening levels.

▪ Concentrations are consistent with historical results for the downstream surface water collected.

▪ Concentrations of TPH (after silica gel clean-up) in SW1 were below the laboratory LOR.

The reported concentrations in samples from LT1 and SW1 are observed to be similar to each other during this monitoring round. This similarity was observed during previous monitoring events.

5.0 QA/QC AND DATA VALIDATIONS The data validation guidelines adopted by Golder provide a consistent approach for the evaluation of analytical data. The process involves the checking of analytical procedure compliance and an assessment of the accuracy and precision of analytical data from a range of QA/QC measures, generated from both the sampling and analytical programs.

Validation summary reports are presented in Appendix E whilst tables of field duplicates are presented in Appendix C. From this information and with reference to the notes and discussion presented in Appendix E it is assessed that the quality of the analytical data is such that it can be used as a basis for interpretation.

Quality test results were generally within acceptable limits and are considered to demonstrate acceptable accuracy and precision.

6.0 CONCLUSIONS Based on the results of the 2019 monitoring round, the following key findings were made:

Groundwater:

▪ Groundwater flow at the site is generally towards the south-east, following the topography and consistent with previous monitoring rounds. The groundwater levels observed during the 2019 monitoring round had decreased since the 2018 monitoring round, however, were within historical ranges.

▪ Based on the inferred groundwater flow direction, monitoring well 65245 is located hydraulically up-gradient of the site and is likely to be representative of background conditions. Monitoring wells 65247, 65246, DH1 and DH2 are located in the inferred down hydraulic gradient direction.

▪ Field parameters taken in-situ were consistent with previous measurements and were within historical ranges.

▪ Boron, cadmium, copper, iron, nickel, zinc, total dissolved solids, nitrite (as N), Total Kjeldahl Nitrogen (as N), total nitrogen, total phosphorus (as P), COD, BOD and magnesium were detected in one or more groundwater wells at concentrations in excess of their respective adopted screening levels, however were within historical ranges.

The leachate tank sample (LT1) had concentrations of heavy metals, trace TRH and other analytes generally consistent with historical ranges presented in AECOM 2018.

The surface water sample (SW1) had concentrations of heavy metals and other analytes generally consistent with historical ranges presented in AECOM 2018. Concentrations of total petroleum hydrocarbons (TPH) were below the laboratory’s LOR.

Conclusions with respect to the monitoring objectives were as follows:

Groundwater monitoring was completed in accordance with the EPA Licence and LEMP.

The 2019 monitoring event results provided no indication of changes in surface water or groundwater quality associated with the closed landfill.

Licence Explanatory Notes – Do Not Form Part of the Licence

Compliance with this licenceThe EPA seeks to ensure that all reasonable and practicable measures are taken to protect, restore and enhance the quality of the environment according to the principles of ecologically sustainable development. To achieve this objective, the EPA uses a number of regulatory decision making principles and actions outlined in the ‘Compliance and enforcement regulatory options and tools’ document available on the EPA website.

Notification – serious or material environmental harm caused or threatenedIf serious or material environmental harm from pollution is caused or threatened in the course of an activity, the licence holder must, as soon as reasonably practicable after becoming aware of the harm or threatened harm, notify the EPA (preferably on EPA emergency phone number 1800 100 833) of the harm or threatened harm, its nature, the circumstances in which it occurred and the action taken to deal with it in accordance with section 83 of the Environment Protection Act 1993 (the Act). In the event that the primary emergency phone number is out of order, the licence holder should phone (08) 8204 2004.

Variations, transfers and surrender of a licenceThe EPA may impose or vary the conditions of a licence by notice in writing to the licence holder in accordance with sections 45 and 46 of the Act. Public notice may be required where the variation of licence conditions results in a relaxation of the requirements imposed for the protection or restoration of the environment and results in an adverse effect on any adjoining land or its amenity. If a licence holder wishes to vary the conditions of a licence, transfer a licence to another entity, or surrender a licence, the licence holder must submit an application to the EPA in accordance with the applicable provisions of the Act (sections 45, 49 and 56, respectively). A licence remains in effect and in its original form until such time as any proposed variation, application for surrender, or transfer has been made and approved in writing by the EPA.

Suspension or cancellation of a licenceThe EPA may suspend or cancel a licence by notice in writing to the licence holder in accordance with section 55 of the Act if satisfied the licence holder has either obtained the licence improperly, contravened a requirement under the Act or if the holder is a body corporate, a director of the body corporate has been guilty of misconduct of a prescribed kind (whether in this State or elsewhere).

Responsibilities under Environment Protection legislationIn addition to the conditions of any licence, a licence holder must comply with their obligations under all State and Federal legislation (as amended from time to time) including: the Environment Protection Act 1993; the Environment Protection Regulations 2009; all Environment Protection Policies made under the Environment Protection Act 1993; and any National Environment Protection Measures not operating as an Environment Protection Policy under the Environment Protection Act 1993

Public Register InformationThe EPA maintains and makes available a Public Register of details related to its determinations and other information it considers appropriate (i.e. excluding trade processes or financial information) in accordance with section 109 of the Act. These details include, but are not limited to:

licensing and beverage container applications and approvals enforcement actions site contamination serious or material environmental harm caused or threatened in the course of an activity environment improvement programmes and environment performance agreements environment assessment reports; results of testing, monitoring or evaluation required by a licence EPA advice or direction regarding development approvals referred to the EPA by a planning authority

Sample HistoryWhere samples are submitted/analysed over several days, the last date of extraction and analysis is reported.A recent review of our LIMS has resulted in the correction or clarification of some method identifications. Due to this, some of the method reference information on reports has changed. However,no substantive change has been made to our laboratory methods, and as such there is no change in the validity of current or previous results.

If the date and time of sampling are not provided, the Laboratory will not be responsible for compromised results should testing be performed outside the recommended holding time.

QC - Acceptance Criteria

QC Data General Comments

1. 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.

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

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

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.

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

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.

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.

Qualifier Codes/Comments

Code Description

N01F2 is determined by arithmetically subtracting the "naphthalene" value from the ">C10-C16" value. The naphthalene value used in this calculation is obtained from volatiles(Purge & Trap analysis).

N02

Where we have reported both volatile (P&T GCMS) and semivolatile (GCMS) naphthalene data, results may not be identical. Provided correct sample handling protocols havebeen followed, any observed differences in results are likely to be due to procedural differences within each methodology. Results determined by both techniques have passedall QAQC acceptance criteria, and are entirely technically valid.

N04F1 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 BTEXanalytes. The "C6-C10" value is obtained by quantitating against a standard of mixed aromatic/aliphatic analytes.

General Comments

The analytical procedures used by the Environmental Division have been developed from established internationally recognized procedures such as those published by the USEPA, APHA, AS and NEPM. In house

developed procedures are employed in the absence of documented standards or by client request.

Where moisture determination has been performed, results are reported on a dry weight basis.

Where a reported less than (<) result is higher than the LOR, this may be due to primary sample extract/digestate dilution and/or insufficient sample for analysis.

Where the LOR of a reported result differs from standard LOR, this may be due to high moisture content, insufficient sample (reduced weight employed) or matrix interference.

When sampling time information is not provided by the client, sampling dates are shown without a time component. In these instances, the time component has been assumed by the laboratory for processing

purposes.

Where a result is required to meet compliance limits the associated uncertainty must be considered. Refer to the ALS Contact for details.

CAS Number = CAS registry number from database maintained by Chemical Abstracts Services. The Chemical Abstracts Service is a division of the American Chemical Society.

LOR = Limit of reporting

^ = This result is computed from individual analyte detections at or above the level of reporting

ø = ALS is not NATA accredited for these tests.

~ = Indicates an estimated value.

Key :

EP026SP (COD); Sample 2 (65246) required x5 dilution due to salinity; LOR adjusted accordingly.l

It has been noted that EK055G (Ammonia as N) is greater than EK061G (Total Kjeldahl Nitrogen as N) for sample EB1924599_007 (LT1), however this difference is within the limits of experimental variation.l

Sodium Adsorption Ratio (where reported): Where results for Na, Ca or Mg are <LOR, a concentration at half the reported LOR is incorporated into the SAR calculation. This represents a conservative approach

for Na relative to the assumption that <LOR = zero concentration and a conservative approach for Ca & Mg relative to the assumption that <LOR is equivalent to the LOR concentration.

General Comments




Where a reported less than (<) result is higher than the LOR, this may be due to primary sample extract/digestate dilution and/or insufficient sample for analysis. Where the LOR of a reported result differs from standard LOR, this may be due to high moisture content, insufficient sample (reduced weight employed) or matrix interference.

Anonymous = Refers to samples which are not specifically part of this work order but formed part of the QC process lot



RPD = Relative Percentage Difference

# = Indicates failed QC

Key :

Laboratory Duplicate (DUP) Report

The quality control term Laboratory Duplicate refers to a randomly selected intralaboratory split. Laboratory duplicates provide information regarding method precision and sample heterogeneity. The permitted ranges

for the Relative Percent Deviation (RPD) of Laboratory Duplicates are specified in ALS Method QWI -EN/38 and are dependent on the magnitude of results in comparison to the level of reporting: Result < 10 times LOR:

No Limit; Result between 10 and 20 times LOR: 0% - 50%; Result > 20 times LOR: 0% - 20%.

Method Blank (MB) and Laboratory Control Spike (LCS) Report

The quality control term Method / Laboratory Blank refers to an analyte free matrix to which all reagents are added in the same volumes or proportions as used in standard sample preparation. The purpose of this QC

parameter is to monitor potential laboratory contamination. The quality control term Laboratory Control Spike (LCS) refers to a certified reference material, or a known interference free matrix spiked with target

analytes. The purpose of this QC parameter is to monitor method precision and accuracy independent of sample matrix. Dynamic Recovery Limits are based on statistical evaluation of processed LCS.

Analysis Holding Time Compliance

Holding times for VOC in soils vary according to analytes of interest. Vinyl Chloride and Styrene holding time is 7 days; others 14 days. A recorded breach does not guarantee a breach for all VOC analytes and

should be verified in case the reported breach is a false positive or Vinyl Chloride and Styrene are not key analytes of interest/concern.

Holding time for leachate methods (e.g. TCLP) vary according to the analytes reported. Assessment compares the leach date with the shortest analyte holding time for the equivalent soil method. These are: organics

14 days, mercury 28 days & other metals 180 days. A recorded breach does not guarantee a breach for all non-volatile parameters.

If samples are identified below as having been analysed or extracted outside of recommended holding times, this should be taken into consideration when interpreting results.

This report summarizes extraction / preparation and analysis times and compares each with ALS recommended holding times (referencing USEPA SW 846, APHA, AS and NEPM) based on the sample container

provided. Dates reported represent first date of extraction or analysis and preclude subsequent dilutions and reruns. A listing of breaches (if any) is provided herein.

General Comments




Where a reported less than (<) result is higher than the LOR, this may be due to primary sample extract/digestate dilution and/or insufficient sample for analysis.

Where the LOR of a reported result differs from standard LOR, this may be due to high moisture content, insufficient sample (reduced weight employed) or matrix interference.

When sampling time information is not provided by the client, sampling dates are shown without a time component. In these instances, the time component has been assumed by the laboratory for processing

purposes.

Where a result is required to meet compliance limits the associated uncertainty must be considered. Refer to the ALS Contact for details.



^ = This result is computed from individual analyte detections at or above the level of reporting

ø = ALS is not NATA accredited for these tests.

~ = Indicates an estimated value.

Key :

Benzo(a)pyrene Toxicity Equivalent Quotient (TEQ) per the NEPM (2013) is the sum total of the concentration of the eight carcinogenic PAHs multiplied by their Toxicity Equivalence Factor (TEF) relative to

Benzo(a)pyrene. TEF values are provided in brackets as follows: Benz(a)anthracene (0.1), Chrysene (0.01), Benzo(b+j) & Benzo(k)fluoranthene (0.1), Benzo(a)pyrene (1.0), Indeno(1.2.3.cd)pyrene (0.1),

Dibenz(a.h)anthracene (1.0), Benzo(g.h.i)perylene (0.01). Less than LOR results for 'TEQ Zero' are treated as zero.

l

EP068 and EP075(SIM): Analysis performed on original EB1924599 EP071 extract. No surrogate or QC reported.l

General Comments




Where a reported less than (<) result is higher than the LOR, this may be due to primary sample extract/digestate dilution and/or insufficient sample for analysis. Where the LOR of a reported result differs from standard LOR, this may be due to high moisture content, insufficient sample (reduced weight employed) or matrix interference.

Anonymous = Refers to samples which are not specifically part of this work order but formed part of the QC process lot



RPD = Relative Percentage Difference

# = Indicates failed QC

Key :

Laboratory Duplicate (DUP) Report

The quality control term Laboratory Duplicate refers to a randomly selected intralaboratory split. Laboratory duplicates provide information regarding method precision and sample heterogeneity. The permitted ranges

for the Relative Percent Deviation (RPD) of Laboratory Duplicates are specified in ALS Method QWI -EN/38 and are dependent on the magnitude of results in comparison to the level of reporting: Result < 10 times LOR:

No Limit; Result between 10 and 20 times LOR: 0% - 50%; Result > 20 times LOR: 0% - 20%.

l No Laboratory Duplicate (DUP) Results are required to be reported.

Method Blank (MB) and Laboratory Control Spike (LCS) Report

The quality control term Method / Laboratory Blank refers to an analyte free matrix to which all reagents are added in the same volumes or proportions as used in standard sample preparation. The purpose of this QC

parameter is to monitor potential laboratory contamination. The quality control term Laboratory Control Spike (LCS) refers to a certified reference material, or a known interference free matrix spiked with target

analytes. The purpose of this QC parameter is to monitor method precision and accuracy independent of sample matrix. Dynamic Recovery Limits are based on statistical evaluation of processed LCS.

Analysis Holding Time Compliance

Holding times for VOC in soils vary according to analytes of interest. Vinyl Chloride and Styrene holding time is 7 days; others 14 days. A recorded breach does not guarantee a breach for all VOC analytes and

should be verified in case the reported breach is a false positive or Vinyl Chloride and Styrene are not key analytes of interest/concern.

Holding time for leachate methods (e.g. TCLP) vary according to the analytes reported. Assessment compares the leach date with the shortest analyte holding time for the equivalent soil method. These are: organics

14 days, mercury 28 days & other metals 180 days. A recorded breach does not guarantee a breach for all non-volatile parameters.

If samples are identified below as having been analysed or extracted outside of recommended holding times, this should be taken into consideration when interpreting results.

This report summarizes extraction / preparation and analysis times and compares each with ALS recommended holding times (referencing USEPA SW 846, APHA, AS and NEPM) based on the sample container

provided. Dates reported represent first date of extraction or analysis and preclude subsequent dilutions and reruns. A listing of breaches (if any) is provided herein.

Surrogate Compound Monitoring Analyses

FD and FT results exceeding an RPD of 20 had a primary concentration greater than the duplicate sample. The elevated RPDs are generally a result of low precision that is typically associated with comparison of analyte concentrations close to labortory limts of reporting.

Field Duplicates (FD) Analyses- QC Outliers

Rinse Blank R01 had results above the LOR in all metals (excluding cadmium). R01 was taken after sampling well 65245 and prior to sampling DH4. Results in both wells for cadmium, chromium, copper, lead, mercury and zinc (DH4) were all reported below the LOR, suggesting metals detected in R01 were not assocaited with cross contamination from either well. The elevated concentrations of metals in R01 may be assocaited with laboratory supplied water. Metals results in primary samplers were within historical results. It is considered unlikely that samples were impacted as a result of cross contamination from sampling equipment.

This batch has been validated and is considered suitable for environmental interpretive use.

All surrogates were within the laboratory control limits.

If a matter is not addressed in this Report, do not assume that any determination has been made by Golder in regards to it.

At any location relevant to the Services conditions may exist which were not detected by Golder, in particular due to the specific scope of the investigation Golder has been engaged to undertake. Conditions can only be verified at the exact location of any tests undertaken. Variations in conditions may occur between tested locations and there may be conditions which have not been revealed by the investigation and which have not therefore been taken into account in this Report.

Golder accepts no responsibility for and makes no representation as to the accuracy or completeness of the information provided to it by or on behalf of the Client or sourced from any third party. Golder has assumed that such information is correct unless otherwise stated and no responsibility is accepted by Golder for incomplete or inaccurate data supplied by its Client or any other person for whom Golder is not responsible. Golder has not taken account of matters that may have existed when the Report was prepared but which were only later disclosed to Golder.

Having regard to the matters referred to in the previous paragraphs on this page in particular, carrying out the Services has allowed Golder to form no more than an opinion as to the actual conditions at any relevant location. That opinion is necessarily constrained by the extent of the information collected by Golder or otherwise made available to Golder. Further, the passage of time may affect the accuracy, applicability or usefulness of the opinions, assessments or other information in this Report. This Report is based upon the information and other circumstances that existed and were known to Golder when the Services were performed and this Report was prepared. Golder has not considered the effect of any possible future developments including physical changes to any relevant location or changes to any laws or regulations relevant to such location.

Where permitted by the Contract, Golder may have retained subconsultants affiliated with Golder to provide some or all of the Services. However, it is Golder which remains solely responsible for the Services and there is no legal recourse against any of Golder’s affiliated companies or the employees, officers or directors of any of them.

By date, or revision, the Report supersedes any prior report or other document issued by Golder dealing with any matter that is addressed in the Report.

Any uncertainty as to the extent to which this Report can be used or relied upon in any respect should be referred to Golder for clarification
