Executive Summary
Environmental Strategies Pty Limited (ES) was commissioned by Prysmian Cables & Systems Australia Pty Ltd (Prysmian) to conduct a Groundwater Monitoring Event (GME) in accordance with the ES (November 2013) Environmental Management Plan (EMP) for a portion of the site known as the coolant leak area located at 1 Heathcote Road, Liverpool NSW (the site). The site location is provided on Figure 1, Appendix A and the site layout in Figure 2, Appendix A.
A coolant leak was first identified in February 2012 within Factory 2 of the site, where an estimated 10,000 – 11,000L of coolant (hydrocarbon/water mixture) was lost to the subsurface due to a fault that had developed within an in-ground concrete pit.
Prysmian made a commitment to conduct monthly monitoring of groundwater around the in-ground pit for an initial three (3) month period with the last event occurring in February 2014. The data trends at the end of the three months of monitoring indicated that the groundwater was not impacted by the leaking pit.
The NSW EPA voiced concerns that the identified petroleum hydrocarbons in the soil may migrate to underlying groundwater. ES concluded that the hydrocarbons in soil have not impacted underlying groundwater at the time and are unlikely to migrate into the deeper soil profile. Nevertheless, as a due diligence measure, the Remedial Action Plan (RAP) prepared by Prysmian Group (June 2013) recommended that ongoing groundwater monitoring be incorporated into the site’s EMP. A less frequent monitoring period was justified and a 12 monthly groundwater monitoring program was adopted. However if groundwater at any time is shown to have been impacted by the contaminants of concern as triggered by the assessment criteria, then contingency options will be assessed.
This report presents the results of the 12 monthly GME.
The results of the February 2016 GME are summarised as follows:
Groundwater analytical results reported all contaminants of concern (total recoverable hydrocarbons (TRH), benzene, ethylbenzene, xylenes and naphthalene (BTEXN)) were either below laboratory limit of reporting (LOR) or the adopted groundwater acceptance criteria (GAC);
With the exception of copper at MW4 (5ug/L), concentrations of heavy metals were reported below the GAC;
Given that no hydrocarbons were reported above the adopted groundwater criteria, this indicates that groundwater has not been impacted by the leaking coolant tank.
Based on the above conclusions, and the results of the ES (June 2013) Supplementary Soil and Groundwater Investigation, ES consider that the coolant leak has not impacted the underlying groundwater and recommends that no further groundwater monitoring (other than that conducted as part of the facility’s due diligence) is required.

1 Introduction
1.1 Background
Environmental Strategies Pty Limited (ES) was commissioned by Prysmian Cables & Systems Australia Pty Ltd (Prysmian) to conduct 12 monthly Groundwater Monitoring Events (GMEs) as specified in an ES (November 2013) Environmental Management Plan (EMP) for a portion of the site known as the coolant leak area located at 1 Heathcote Road, Liverpool NSW (the site). The site location is provided on Figure 1, Appendix A and the site layout in Figure 2, Appendix A.
A coolant leak was first identified in February 2012 within Factory 2 of the site, where an estimated 10,000 – 11,000L of coolant (hydrocarbon/water mixture) was lost to the subsurface due to a fault that had developed within an in-ground concrete pit. Following submission of a pollution incident report and sampling plan by MJM Environmental, Benbow Environmental (BE) were commissioned in July 2012 to undertake an Environmental Site Assessment (ESA) to investigate the extent of the release.
Investigations of soil and groundwater were undertaken by Benbow Environmental Pty Ltd (BE) and ES in 2013.
The results of the BE (January 2013) Environmental Site Assessment and the ES (June 2013) Supplementary Soil and Groundwater Investigation can be summarised as follows:
Soil results as reported by BE showed that sample locations 7, 8 and 9 contained contaminant concentrations below health based criteria but exceed the NEPM (2013) Commercial/Industrial Management Limits for coarse soil at depths ranging between 2 and 4.5m below ground level (bgl);
Impacted soils are localised to the southern and eastern portion of the in-ground pit, between 2 and 4.5m bgl;
The results of the ES soil investigation reported no exceedances of hydrocarbons in soil above the adopted criteria (or concentrations above laboratory detection limits) at depths greater than 4.5m bgl;
Groundwater analytical results reported all contaminants of concern (TRH, BTEX, PAH and heavy metals) below laboratory reporting limits and the adopted groundwater acceptance criteria (GAC) with the exception of copper and zinc, for which reported concentrations were marginally above the GAC. ES consider that the concentrations of copper and zinc detected in groundwater are unlikely to be related to the coolant use/spill. The concentrations of copper and zinc are likely representative of local background levels and are unlikely to pose a risk to human health and the environment;
No TRH concentrations were reported above the adopted groundwater criteria indicating that groundwater had not been impacted by the leaking coolant tank; and
The soil and groundwater around the tank were considered suitable for the continued commercial/industrial land use.
Following the submission of BE (January 2013), ES (June 2013) and a Remedial Action Plan (RAP) prepared by Prysmian (June 2013), the NSW EPA voiced concerns that the identified petroleum hydrocarbons in soil may migrate to underlying groundwater.
A letter report was prepared by ES (August 2013) discussing the hydrocarbon impacted soil and its potential to migrate to the underlying groundwater. ES concluded that the hydrocarbons in soil have not impacted underlying groundwater and are unlikely to migrate into the deeper soil profile. Nevertheless, as a due diligence measure, the Remedial Action
Prysmian Power Cables & Systems Australia Pty Ltd, February 2016 Groundwater Monitoring Event, 1 Heathcote Road, Liverpool, NSW 2 16021
Plan (RAP) prepared by Prysmian Group (June 2013) recommended that ongoing groundwater monitoring be incorporated into the site’s EMP with a contingency plan should groundwater impact be detected from this event in the future.
Prysmian made a commitment to conduct monthly monitoring of groundwater around the in-ground pit for three (3) months. At the end of the three months of monitoring, the data trends indicated that the groundwater was not impacted by the leaking pit. For due diligence measures Prysmian decided that a 12 monthly groundwater monitoring program was justified providing that if groundwater at any time shows to have been impacted by the contaminants of concern as triggered by the assessment criteria, then contingency options will be assessed.
This report presents the results of the February 2016 GME.
1.2 Objective
Within the original scope provided, the objective of the GME was to:
Determine whether groundwater had been impacted from localised leak of ‘coolant’ and if these impacts, if present, exceeded the adopted human health and environmental criteria or otherwise.
1.3 Scope of Works
ES completed the following scope of works:
Preparation of a Job Hazard Analysis (JHA);
Gauging to depth of water (and light non-aqueous phase liquids (LNAPLs) if present) in five (5) monitoring wells;
Measurement of field groundwater quality parameters (dissolved oxygen (DO), electrical conductivity (EC), pH, redox potential (Eh) and temperature) of stabilised purged groundwater;
Sampling of groundwater from all five (5) accessible groundwater monitoring wells using micro-purge pump and submitted to NATA accredited laboratory Envirolab for analysis of Total Recoverable Hydrocarbons (TRH C6-C40), Benzene, Toluene, Ethylbenzene, Xylenes and naphthalene (BTEXN) and Arsenic, Cadmium, Chromium, Copper, Lead, Mercury, Nickel, Zinc (Metals);
Collection of Quality Assurance and Quality Control (QA/QC) (collected at a rate of 1:20) including one duplicate, one triplicate and forward these to a NATA accredited laboratory for analysis;
Assessment of analytical data against the following guidelines:
- NEPC (2013) NEPM Investigation Levels for Soil and Groundwater; and

The subject site is bounded by Factory 1 to the west, the centre line of Factory 2 to the east, the access road to the south and the third bay (as specified by the saw tooth roofing panels) of Factory 2 to the North. The subject site area is approximately 1,120m2.
2.2 Possible Contaminant Sources on the Site
An inspection was limited to Factory 2 (the cable drawing building), refer to Figure 2, Appendix A for site layout. Possible contamination sources in this area included the coolant tank (which was replaced immediately after the leak was notified in February 2012) and the coolant mixture itself (Houghto Draw WD4100) which is stored in drums along the south wall, near to the second entrance door. The composition of the coolant includes several petroleum based compounds and additives and requires dilution with water. The time weighted exposure limit for Houghto Draw WD4100 is listed as 5 mg/m3.

3 Sampling and Analysis Plan and Sampling Methodology
This section outlines the methodology adopted by ES during the GME. This section also provides details on the sampling and analysis, description of field equipment used, decontamination procedures, field and laboratory quality assurance and control, laboratory analytical methods and sample preservation.
3.1 Groundwater
3.1.1 Groundwater Gauging, Purging and Sampling
Groundwater gauging, purging and sampling was completed by ES’ Environmental Scientist Colin Biggs on 8th February 2016.
Samples were collected from the five (5) wells in the vicinity of the reported coolant leak. Refer to Figure 3, Appendix A.
Prior to sampling, all wells were gauged with an interface probe to measure groundwater levels and detect the presence of light non-aqueous phase liquids (LNAPL). All monitoring wells were then purged using a peristaltic pump to ensure minimal losses of volatile organic compounds.
Water quality parameters recorded included pH, redox potential (Eh), electrical conductivity, dissolved oxygen and temperature. All wells were purged until groundwater parameters stabilised to within suitable limits.
Samples were placed directly into appropriately preserved laboratory supplied sampling containers. The sample for metals analysis was filtered in the field using a 0.45micron millipore filter unit prior to analysis.
Disposable tubing was used at each monitoring well and the interface probe was thoroughly decontaminated between gauging events with a phosphate free detergent (Decon 90) and rinsed with potable water. Field records of purging and sampling event are provided in Appendix C.
3.1.2 Field QA/QC
The following procedures were followed during fieldwork to ensure quality control:
Water samples were collected in laboratory supplied bottles with Teflon seals;
Samples were collected from disposable equipment to prevent cross contamination between sampling locations;
Samples were placed in an ice-filled esky to keep them below 4oC in accordance with US EPA SW 846 and AS4482-2 (2005); and
Samples were transferred to the laboratory under a completed chain-of-custody.

4 Field Quality Assurance and Quality Control (QA/QC)
4.1 Chain of Custody
Samples were transferred to the laboratory under chain-of-custody procedures. The details included on the chain-of-custody forms included the following:
Job name and number Date results are required List of samples Preservation method Analysis required Release signature and date Date sampled Acceptance signature and date
4.2 Statement of Duplicate Frequency
The following are QA/QC samples were collected for this project:
DUP1 and TRIP1 were a groundwater intra-laboratory and inter-laboratory duplicate of MW2.
Precision of analytical techniques is measured by the relative percent difference (RPD) between duplicate results. Acceptable precision shown by intra-laboratory and inter-laboratory duplicate samples is:
Precision is measured using the standard deviation ‘SD’ or Relative Percent Difference ‘%RPD’. Replicate data for field duplicates of organics is expected to be as follows:
RPD criteria of 50% or less, for concentrations > or = 10 times EQL; RPD criteria of 75% or less, for concentrations between 5 and 10 times the EQL; and RPD criteria of 100% or less, for concentrations < 5 times EQL.
Replicate data for field duplicates for inorganics, including metals is expected to be as follows:
RPD criteria of 30% or less, for concentrations > or = 10 times EQL; RPD criteria of 75% or less, for concentrations between 5 and 10 times the EQL; and RPD criteria of 100% or less, for concentrations < 5 times EQL.
A summary of the Relative Percent Differences (RPDs) calculations are presented in Table 2a, Appendix B. ES notes that RPDs were only calculated for groups of compounds with detections above the laboratory detection limits.
All RPDs for groundwater were within acceptable ranges with the exception of the following;
Primary sample (MW2) and DUP1 RPD exceedance 80% for Zinc
The RPD exceedance for zinc marginally exceeds the 75% criteria. Given that the concentrations of all contaminants of concern were below the adopted GAC, ES considers the minor RPD exceedance does not affect the validity of the data collected.
Overall, there is an acceptable level of agreement between original and duplicate samples indicating that field procedures were adequate in obtaining representative samples and minimising the potential for cross‐contamination.
4.3 Background Sample Results
Background samples were not collected as part of this investigation.
4.4 Rinsate Sample Results
A rinsate sample was not collected from the final decontamination of the interface probe and purged water bucket. Dedicated sampling materials and best practice sampling methods were

6 Assessment Criteria
6.1 Rationale for Selection of Water Assessment Criteria
In accordance with the NEPM (2013) Schedule B(6) The Framework for Risk Based Assessment of Groundwater Contamination it was necessary to determine the relevant environmental values and hence appropriate guideline assessment criteria for the site.
To determine the most appropriate groundwater guideline the following environmental values have been considered and are presented in Table 6.1. These have been referenced from Appendix 2 of NSW DEC (2007) Guidelines for the Assessment and Management of Groundwater Contamination and the NEPM (2013) Schedule B (6).

Environmental Values
ES Comment
Aquatic Ecosystems (Freshwater)
The closest surface water receptor is the Georges River located along the western boundary of the site. The Georges River would be classed as a beneficial receptor of groundwater and should be protected. This is classed as a freshwater environment.
Human Uses (Drinking Water)
No registered groundwater bores for domestic use were identified within 500km of the site. EC measurements of the groundwater monitoring bores indicated a TDS

7 Results
The following section presents an overview of the field observations for groundwater encountered during the February 2016 GME. Copies of groundwater sampling field sheets are included in Appendix C.
7.1 Groundwater Gauging Results
Groundwater gauging results are summarised below:
LNAPL was not detected in any of the monitoring wells sampled; and Depth to groundwater ranged between 5.741m below top of casing (btoc) at MW1 and
6.153m btoc at MW5. Refer to Table 1 Appendix B for corrected water relative levels (RLs).
7.2 Groundwater Quality Results
During sampling the groundwater was observed to be light brown to dark brown in colour, odourless with suspended clay particles. No sheens were observed in any of the purged water. The groundwater field parameters for the site are summarised in Table 7.2 below:

MW5 08/02/2016 21.2 5.29 0.94 218 305
Table 7.2 indicates the following groundwater conditions: The temperature of the groundwater ranged from 21.2 to 23.2oC; pH ranged from 5.29 to 5.79 pH units indicating slightly acidic groundwater conditions; Dissolved oxygen in the groundwater ranged from 0.94 and 3.15 ppm indicating
generally aerobic conditions; ORP (oxidation reduction potential) levels measured from 164 to 250mV (using a
Ag/AgCl electrode), which indicates oxidising conditions. ORP (or Redox) is a measure of a water system’s capacity to either release or gain electrons in chemical reactions. The process of oxidation involves losing electrons while reduction involves gaining electrons; and
Conductivity levels were between 287 and 700 (µS/cm), which indicates fresh groundwater conditions.
The following presents a summary of results for groundwater samples. Result summary tables are included in Appendix B, with copies of laboratory certificates included in Appendix D.

7.3 Groundwater Analytical Results
7.3.1 Heavy Metals
Concentrations of heavy metals in all groundwater samples submitted for analysis were reported below the GAC with the exception of copper at MW4.
7.3.2 BTEXN
Concentrations of BTEXN in all groundwater samples submitted for analysis were reported below laboratory detection limits with the exception of Toluene (2µg/L) in MW 1 which is below the adopted GAC.
7.3.3 TRH
Concentrations of TRH in all groundwater samples submitted for analysis were reported below laboratory detection limits and the adopted GAC.
7.3.4 Discussion
The results of this investigation indicate that with the exception of a low level detection of Toluene in MW1, no detectable petroleum hydrocarbon contamination was present in any of the up-gradient or down-gradient monitoring well locations above the adopted groundwater acceptance criteria (GAC).
The recent groundwater monitoring data was compared to that of the previous GME events that occurred in September 2013, December 2013, February 2014 and February 2015. Table 3 Appendix B shows a comparison of analytical results from these four rounds.
ES consider that the concentrations of copper, nickel and zinc detected in groundwater are unlikely to pose a risk to human health and the environment and are likely representative of local background levels.

8 Conclusions and Recommendations
8.1 Conclusions
The following conclusions can be made from the February 2016 GME conducted at the site located at 1 Heathcote Road, Liverpool:
Groundwater analytical results reported all contaminants of concern (TRH, and BTEXN) below laboratory detection limits and the adopted groundwater acceptance criteria (GAC)
With the exception of copper at MW4 (5ug/L), concentrations of heavy metals were reported below the GAC. ES consider that the concentrations of copper, nickel and zinc detected in groundwater are unlikely to pose a risk to human health and the environment and are likely representative of local background levels;
No TRH concentrations were reported above the adopted groundwater criteria indicating that groundwater has not been impacted by the leaking coolant tank;
Toluene was detected above the LOR at one monitoring well (MW1); and
This GME is the fifth (5) monitoring event after the preparation of the RAP and confirms the findings of the ES (June 2013) report, that the groundwater has not been impacted by the leaky coolant tank.
8.2 Recommendations
Based on the above conclusions, and the results of the ES (June 2013) Supplementary Soil and Groundwater Investigation, ES consider that the coolant leak has not impacted the underlying groundwater and recommends that no further groundwater monitoring (other than that conducted as part of the facility’s due diligence) is required.
8.3 Extent of Uncertainties in the Results
The sampling methodologies used by ES during this assessment have been designed to limit uncertainty in the results. ES is confident that the results of this assessment give an accurate representation of the current status of the site but note that in all subsurface investigations the potential remains for variation between sampling points and conditions different from that reported here may exist on site.

Method ID Methodology Summary
Org-016 Soil samples are extracted with methanol and spiked into water prior to analysing by purge and trap GC-MS. Water samples are analysed directly by purge and trap GC-MS. F1 = (C6-C10)-BTEX as per NEPM B1 Guideline on Investigation Levels for Soil and Groundwater.
Org-013 Water samples are analysed directly by purge and trap GC-MS.
Org-003 Soil samples are extracted with Dichloromethane/Acetone and waters with Dichloromethane and analysed by GC-FID. F2 = (>C10-C16)-Naphthalene as per NEPM B1 Guideline on Investigation Levels for Soil and Groundwater (HSLs Tables 1A (3, 4)). Note Naphthalene is determined from the VOC analysis.
Metals-022 ICP-MS Determination of various metals by ICP-MS.
Metals-021 CV-AAS
Determination of Mercury by Cold Vapour AAS.

Quality Control Definitions
Blank: This is the component of the analytical signal which is not derived from the sample but from reagents, glassware etc, can be determined by processing solvents and reagents in exactly the same manner as for samples. Duplicate : This is the complete duplicate analysis of a sample from the process batch. If possible, the sampleselected should be one where the analyte concentration is easily measurable. Matrix Spike : A portion of the sample is spiked with a known concentration of target analyte. The purpose of the matrix spike is to monitor the performance of the analytical method used and to determine whether matrix interferences exist. LCS (Laboratory Control Sample) : This comprises either a standard reference material or a control matrix (such as a blanksand or water) fortified with analytes representative of the analyte class. It is simply a check sample. Surrogate Spike: Surrogates are known additions to each sample, blank, matrix spike and LCS in a batch, of compoundswhich are similar to the analyte of interest, however are not expected to be found in real samples.
Laboratory Acceptance Criteria
Duplicate sample and matrix spike recoveries may not be reported on smaller jobs, however, were analysed at a frequencyto meet or exceed NEPM requirements. All samples are tested in batches of 20. The duplicate sample RPD and matrixspike 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: 5xPQL - 0-50% RPD is acceptable.Matrix Spikes, LCS and Surrogate recoveries: Generally 70-130% for inorganics/metals; 60-140%for organics (+/-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 validityof the analysis where recommended technical holding times may have been breached.
