Executive Summary
URS Australia (URS) was commissioned by Sydney Water Corporation (SWC) to undertake a soil
investigation at the SWC owned land identified as Lot 1 in DP813900 located in Hillsdale, NSW (the
site). The site locality is shown on Figure 1.
URS understands that the Environmental Protection Agency (EPA) provided SWC with information
relating to a soil investigation that was undertaken on the western portion of the SWC site. The final
EPA results were received by SWC on 27 May 2013. The EPA results reported some contamination
issues were evident on the site. However, the nature and distribution of contaminants of potential
concern (COPC) across the entire site was unknown, thus the purpose of this investigation was to
characterise the soil for the presence of COPC.
The COPCs from the EPA results included Polychlorinated biphenyls (PCBs), hexachlorobenzene
(HCB) and mercury. In addition, URS included the following COPCs for this investigation:
organochlorine pesticides (OCPs), Polycyclic Aromatic Hydrocarbons (PAHs), asbestos and eight
priority heavy metals.
In total 18 sample locations were hand augered and sampled in a grid formation covering the entire
site (see Figure 2). Two samples were collected from each of the 18 sample locations, one at 0.05
metres below ground surface (mbgs) and one at 0.15 mbgs. All surface soil samples and some
subsurface soil samples were dispatched to a National Association of Testing Authorities (NATA)
accredited laboratory for analysis of the COPC.
URS conclude the following based on the results of this investigation:
• The analytical results for the individual samples collected by URS show that the COPCs are below
the land use criteria for Recreational C (NEPM 1999 as amended 2013) for all COPCs, the
exception being Benzo(a)Pyrene (BaP) and PCBs at some locations.
• The soil analytical results for BaP indicate that there is a localised area of contamination at sample
location HA17 in the surface soils at 0.05 mbgs. The impact is vertically delineated to the upper
0.15 mbgs, however lateral delineation is not known. The source of the contamination is not known;
however is potentially related to anthropogenic materials in the surface fill soils.
• The soil analytical results for Total Polychlorinated Biphenyls (PCB) indicate that there are three
samples that exceed the Health-based Investigation Levels (HILs) for Recreational land use at
HA01 (0.15 mbgs), HA04 (0.05 mbgs) and QC101 (field duplicate at HA05 0.05 mbgs). The source
of the PCB impacts is not known.
• The soil analytical results for total PCBs (including both the URS and EPA results) were statistically
calculated for the 95% Upper Confidence Limit (UCL) of the arithmetic mean of PCB
concentrations. The 95% UCL for total PCBs in the surface soils onsite was calculated to be
0.65 mg/kg, which is below the NEPM HIL of 1.0 mg/kg for PCBs in Recreational land use settings.
Therefore total PCBs in surface soils meet the HILs for Recreational land use.
Based on the conclusions above, URS recommend the following:
• The BaP contamination in the localised area at HA17 warrants lateral delineation. This can be
achieved through further soil investigations in close proximity to the HA17 sampling location. This
fieldwork was approved by SWC and conducted by URS on 10 July 2013.
• As a temporary measure to control public access to the surface soils at HA17, SWC should
continue maintaining a thick growth of turf across this area.
This executive summary is subject to the full limitations as stated in Section 8 of this report.

1Introduction
1.1 Preamble
URS Australia (URS) was commissioned by Sydney Water Corporation (SWC) to undertake a soil
investigation at the SWC owned land identified as Lot 1 in DP813900 located in Hillsdale, NSW (the
site). The location of the site is shown on Figure 1.
The NSW Environment Protection Authority (EPA) undertook soil sampling of an area at the western
end of the site, and areas offsite, to assess for the presence of chemicals in surface soils. Six
sampling locations (SS01 – SS06) were located on the site and the results showed detections of
pesticides, polychlorinated biphenyls (PCBs) and lead. Given the detections of chemicals on the site,
SWC wished to assess the remaining surface soils across the entire site.
1.2 Objectives
The purpose of this investigation was to characterise the surface soil for the presence of chemicals of
potential concern (COPCs) and compare the results against human Health-based Investigation Levels
(HILs) for assessing risk to human health in open space land use settings.
The COPCs from the EPA sampling included Polychlorinated Biphenyls (PCBs), hexachlorobenzene
(HCB) and mercury. In addition, URS included the following COPCs for this investigation:
organochlorine pesticides (OCPs), Polycyclic Aromatic Hydrocarbons (PAHs), asbestos and eight
priority heavy metals.
This investigation did not include an assessment for ecological receptors, or receptors of groundwater
at the site or offsite.
1.3 Scope of Work
The following scope of work was completed by URS:
Pre Works
• URS secured the services of an independent NATA accredited primary laboratory for receipt
and processing of site samples (including QA/QC) with delivery of analytical results to URS.
• Preparation of a site-specific Health, Safety and Environment Plan (HSEP) following URS
policies and procedures that will comply with SWC requirements as well for the protection of
URS staff on site including the provision of health and safety gear and equipment for URS
staff.
• On-line application of Dial Before You Dig (DBYD) plans for the site.
• Review of the NSW EPA analytical results.
• Review of groundwater information from the NSW Natural Resource Atlas.
• Preparation of a sampling plan to document the methodology, processing and procedures
conforming to the collection and production of environmental data. The sampling plan
identified an agreed suite of analysis for COPC. The sampling plan was set up with sample
locations spread evenly across the entire site in a grid formation. The sampling strategy was
agreed upon with SWC in consideration of the NSW EPA Sampling Design Guidelines 1995
prior to sampling commencing.

2Site Information
2.1 Site Identification
The site is described as follows:
Table 2-1 Site Description Summary
Lot/DP Lot 1 in DP813900
Owner Sydney Water Corporation
Site Area Approximately 1.27 hectares
Zoning The site is zoned 6(a) Open Space and Recreation in the Botany Local
Environment Plan 1995.
Current Land Use The site is a grassed area that is open to the public. Predominantly used by the
public as a pedestrian thoroughfare. There is a small children’s playground
found on-site (including a swing set) located adjacent to Rhodes Street (eastern
end of site).
Grace Campbell Reserve adjoins the site on the central southern site boundary.
There is no boundary fence separating the two areas.
SWC operates a number of services through this site with a large sewer main
identified by SWC as Southern and Western Suburbs Ocean Outfall Sewer
(SWSOOS) No.1 passing through the length of the site (travelling north-west to
south-east). The sewer has a large desilt opening and junction point located on
the sewer line within the central portion of the site.
Additionally, there is a stormwater drain that runs north-south across the central
portion of the site. The stormwater pollution trap is found centrally on-site.
Photos of the site are presented in Plates 1 to 5 (Appendix E).
Surface Cover The site is a predominantly grassed area with few trees found across the site.
Upon completion of site works, the URS field personnel noted that the western
half of the site generally appeared to have thinner grass coverage with some
patches of exposed soil observed across the area. The exposed soil patches
looked to form a path, indicating that this is the location most pedestrians walk
through the site.
The eastern half of the site generally showed thicker grass coverage with no
exposed soil patches observed.
The onsite children’s swingset had a thin cover of woodchips over sand to the
depth of the sampling (i.e. 0.15 mbgs).
See Table 1 (attached) for surface cover conditions at each sample location.

2.2 History
The NSW EPA undertook soil sampling of the area adjacent to and on the site. Of the 15 soil samples
collected by the EPA across the area, six sampling locations (SS01 – SS06) were located on the SWC
site, as shown on Figure 2. The EPA collected surface soil samples and chemically analysed the soil
samples for OCPs, PCBs and metals. Table 2-2 below presents a summary of the EPA’s results. The
contaminants of concern in this investigation were Aroclor 1254 (PCB) and Lead, with the bold
numbering within the table indicating the soil results exceeding the NEPM 1999 (amended 2013) HIL
C for soil contaminants on public open space land use.

3Investigation Criteria
3.1 Soils
The National Environment Protection Measure 1999 (NEPM 1999 as amended 2013) provides risk-
based Health-based Investigation Levels (HILs) for selected organic and inorganic chemicals in soils.
Different levels are provided for a variety of exposure settings including residential, open-
space/parks/recreational and commercial/industrial land uses.
The NEPM 1999 HILs have been developed to be protective of human health and do not take into
account environmental concerns. According to Botany Council the current site land use zoning is 6(a)
open space and recreation, therefore soil results have been compared to NEPM HIL Recreational C
concentrations for the COPCs.

4Methodology
4.1 Soil Sampling Programme
All works were conducted in accordance with a URS site specific Health, Safety and Environment Plan
(HSEP) and the sampling plan approved by SWC. Soil sampling design was based on NSW EPA
Sampling Design Guidelines 1995. The sequence of works was as follows:
Site Works – 12th June 2013
• A site walkover inspection, including review of the DBYD Plans and site observations to select
suitable investigation locations;
• Removal of 0.2 m x 0.2 m wide turf layer at each of the 18 sample locations;
• Hand augering of 18 locations, taking representative samples from 0.05 mbgs and 0.15 mbgs, for
analysis of selected COPC;
• Reinstatement of the 0.2 x 0.2 m wide turf layer at each of the 18 sample locations (see Plate 6);
• Decontamination of all sampling equipment and tools;
• Photos taken of the site and each individual sample location; and
• Collection of GPS co-ordinates and heights (mAHD) at each of the 18 sample locations (refer to
Table 1 (attached)).
4.1.1 Sampling Density
The site is approximately 1.27 hectares. The design for the soil investigation comprised a systematic
grid-based sampling basis to identify impacts and characterise the nature of soils. The sampling
density for this site included:
• Eighteen sample locations investigated by URS June 2013; and
• Six sampling locations investigated by EPA in April 2013.
In total 24 sampling locations was considered to be representative of soils observed across the site.
4.1.2 Sample Methodology
Soil was collected by use of a hand auger and collected by hand off the hand auger. The hand auger
was decontaminated between each sample location. To avoid cross contamination of soil samples,
nitrile gloves were worn and changed between each sample. Soil samples were then placed into acid-
washed glass jars with Teflon® lids, provided by the laboratory. The soil jars were then placed in a
chilled ice chest (esky) for delivery to the laboratory. The samples were accompanied by a chain of
custody (COC) form identifying the analyses required for each sample. Copies of the chain of custody
forms are included in Appendix G. Samples were collected at 0.05 metres below ground surface
(mbgs) and at 0.15 mbgs.
Field indication of volatile compounds in soil was measured using representative soil from samples
observed with potential impact. This soil was placed inside a zip-lock bag and screened using a
calibrated portable photo-ionisation detector (PID). Results of field PID analyses are reported on bore
logs (Appendix B).
4.2 Quality Assurance and Quality Control
Sampling protocol followed the procedures set out in Australian Standard (AS4427.1-2005), Guide to
the Sampling and Investigation of Potentially Contaminated Soil, Part 1: Non-volatile and semi-volatile
compounds.
SWC Hillsdale Soil Investigation
4 Methodology
10 43218409/01/01
To prevent cross contamination, all equipment and tool used on-site (including shovel and hand
auger) were decontaminated between each sampling location. The decontamination procedure
comprises of the following stages;
1. Remove encrusted materials by use of a stiff brush;
2. Scrub with brushes and a cleaning solution (Decon 90 mixed with potable water); and
3. Rinse with lab provided de-ionised water.
Disposable nitrile gloves were used to collect soil samples, with a new pair used for each sample
location and depth.
Quality control samples were collected during the soil investigation as outlined below:
• One intra-laboratory field duplicate sample in every ten primary samples was collected by
splitting a sample into the primary and duplicate sample containers;
• A rinsate blank was collected by pouring laboratory prepared supplied deionised water over
the sampling equipment, one is required per day of field works; and
• One trip blank sample, comprising of laboratory prepared blank soil/sand sample was also
included with each ice chest (esky). The trip blank is quality assurance for any potential cross
contamination that may occur during transport.
Each sample was labelled with a unique identifier and placed directly into an ice chest (esky). The
samples were then transported to the laboratory under URS chain-of-custody (COC) protocols. Copies
of COC documentation are included in Appendix F.

5.1 Field Observations
The site consists predominantly of fill soils. The fill soils on-site are predominantly sand with a mixture
of some gravel and anthropogenic materials (see Appendix C for Test Pit Field Logs). It should be
noted that although some anthropogenic material was identified in the field, the majority of the
anthropogenic material was observed within the soil samples was identified by the NATA approved
laboratory completing the asbestos investigation (see Appendix G for laboratory analytical reports).
No unusual odours were noted during the investigation.
A general description of the stratigraphy encountered on site is summarised below:
Depth (metres) Soil Description
0.0 – 0.15 FILL: SAND; fine to medium grained, dark brown, some
fine to coarse sub-rounded to sub-angular gravels,
some organic material (including roots and
decomposing plant matter), some demolition waste
(including brick, glass and plastic fragments), slightly
moist, loose, no odour. Material becoming light brown
with increasing depth.
See Appendix C for individual Test Pit Field Logs.
Duplicates of all soil samples were collected onsite to screen the head space for the potential
presence of volatile organic compounds (VOCs) using a field portable photo-ionisation detector (PID).
The PID results are included in the field test pit logs completed on site, which are located in
Appendix C.
5.2 Soil Analytical Results
Soil analytical results are presented in the following attached tables:
• Table 2 Soil Analytical Results- June 2013.
• Table 3 Soil QA/QC Analytical Results- June 2013.
• Table 4 Water QA/QC Analytical Results- June 2013.
Table 5-1 below provides a summary of soil analytical results that exceeded the NEPM 1999
(amended 2013) HILs.
Where the maximum concentration of an analyte was above the NEPM HILs, the 95 % upper
confidence limit (UCL) for the analyte was calculated using ProUCL (US EPA). This concentration was
then compared to the soil criteria. The PCB results were the only occasion where this occurred. URS
has included the EPA results for the purposes of calculating the 95 % UCL.
It should be noted that the 95% UCL was not calculated for the Benzo(a)pyrene (BaP) TEQ results
due to the BaP TEQ result for HA17_0.05 (10.6 mg/kg) being greater than 250% the NEPM HIL C
criteria (3.0mg/kg). A result greater than 250% of the criterion is deemed a contamination hotspot and
thus the UCL is not suitable to be used for site characterisation. Once the BaP TEQ contamination
hotspot result was removed from the data set, all other BaP TEQ results met the soil criterion, and
therefore calculation of the 95% UCL was not required.
The outputs from ProUCL are presented in Appendix A.

5.3 Analytical Data Validation
Analytical data validation is the process of assessing whether the data is in compliance with method
requirements and project specifications. The primary objective of this process is to ensure that data of
known quality are reported, and to identify if data can be used to fulfil the overall project objectives.
The data validation guidelines adopted are based upon the following data validation guidance
documents published by the United States Environmental Protection Agency (USEPA):
• USEPA Contract Laboratory Program National Functional Guidelines for Inorganic Data
Review (EPA 540-R-10-011, dated January 2010);
• USEPA Contract Laboratory Program National Functional Guidelines for Organic Data Review
(EPA 540/R-99/008, dated June 2008); and
• NEPM (1999-amended 2013), National Environment Protection (Assessment of Site
Contamination) Measure (NEPM), Guideline on Investigation Levels for Soil and Groundwater.
The process involves the checking of analytical procedure compliance and the assessment of the
accuracy and precision of analytical data from a range of quality control measurements, generated
from both field sampling and analytical programs.
Specific elements that have been checked and assessed for this project include:
• preservation and storage of samples upon collection and during transport to the laboratory;
• holding times;
• use of appropriate analytical procedures;
• required LOR;
• frequency of conducting quality control measurements;
• laboratory blanks;
• field duplicates;
• laboratory duplicates;
• matrix spike / matrix spike duplicates (MS / MSDs);

• surrogates (or System Monitoring Compounds); and
• the occurrence of apparently unusual or anomalous results, e.g. laboratory results that appear
to be inconsistent with field observations or measurements.
Laboratory data validation is included within Appendix F.
On the basis of the analytical data validation procedure employed, the overall quality of the soil
analytical data from the samples collected by URS is considered to be of an acceptable standard.
URS did not assess the validity of the samples collected by the NSW EPA.

6Conclusions & Recommendations
6.1 Conclusions
URS conclude the following based on the results of this investigation:
• The analytical results for the individual samples collected by URS show that the COPCs are
below the land use criteria for Recreational C (NEPM 1999 as amended 2013) for all COPCs,
the exception being BaP and PCBs at some locations.
• The soil analytical results for BaP indicate that there is a localised area of contamination at
sample location HA17 in the surface soils at 0.05 mbgl. The impact is vertically delineated to
the upper 0.15 mbgl, however lateral delineation is not known. The source of the
contamination is not known, however is potentially related to materials in the surface fill
material.
• The soil analytical results for Total Polychlorinated Biphenyls (PCB) indicate that there are
three samples exceed the HIL for Recreational land use at HA01 (0.15 mbgl), HA04
(0.05 mbgl) and QC101 (field duplicate at HA05 0.05 mbgl). The source of the PCB impacts is
not known.
• The soil analytical results for total PCBs (including both the URS and EPA results) were
statistically calculated for the 95% UCL of the arithmetic mean of PCB concentrations. The
95% Kaplan-Meier (t) UCL for total PCBs onsite was calculated to be 0.65 mg/kg, which is
below the NEPM HIL of 1.0 mg/kg for PCBs in Recreational land use settings. Therefore total
PCBs in surface soils meet the HILs for Recreational land use.
6.2 Recommendations
Based on the conclusions above, URS recommend the following:
• The BaP contamination at HA17 warrants lateral delineation. This can be achieved through
further soil investigations in close proximity to the HA17 sampling location. This fieldwork was
approved by SWC and conducted by URS on 10 July 2013.
• As a temporary measure to control public access to the surface soils at HA17, SWC should
continue maintaining a thick growth of turf across this area.
