Executive Summary

D&N Geotechnical Pty Ltd were engaged by Queanbeyan-Palerang Regional Council

(Council) to undertake a preliminary Soil Contamination Assessment (SCA) and an

interim in-situ waste classification of Councils proposed headquarters with basement

carpark on this site, see Figure 1. Ballpark Environmental Pty Ltd (Ballpark )has reviewed

the previous investigation reports, boreholes logs, laboratory results from soil and

groundwater samples and prepared this preliminary SCA report in cooperation with

D&N Geotechnical.

Previous investigations undertaken by Opus (2017) on the adjoining property, Lot 5,

about 70m to the west of this site had noted the presence of petroleum hydrocarbons at

a depth of 6.5mbgs. The petroleum hydrocarbons were logged from the Unit 2b

Alluvium which previous geotechnical investigations have logged to occur on Lot 5 and

this site from about 3.5m to 11mbgs.

The objective of the preliminary SCA was to provide a preliminary assessment of soil and

groundwater contamination and, if required, provide a basis for a more Detailed Site

Investigation.

Based on review of available previous reports, site observations made during the SCA investigation, the limited soil and groundwater sampling, laboratory analysis, and data interpretation, we conclude that:

• The site of the proposed Queanbeyan-Palerang Regional Council administration and library building has previously been used for commercial purposes, as the former Council Chambers building, with no-evidence of former contaminating landuse or activities identified on this site.

• Site soils include imported fill material (surface to ~2.0mbgs) comprising sandy gravel with traces of plastic, terracotta and concrete debris, overlying natural silty clay alluvium (Unit 2A) soils which are overlying natural sandy gravel alluvium (Unit 2B) soils to depth of the investigation.

• Measured groundwater standing water levels from monitoring well MW1 installed on this site was 7.1mbgs.

• Field investigations identified no visual or olfactory indicators of soil contamination. Soil samples screened using a Photo-Ionisation Detector (PID) reported low readings with no evidence of volatile organic compounds.

• Laboratory results for analysis of selected soil samples and groundwater sample from MW1 for petroleum hydrocarbons (TRH/BTEX) and metals were below the adopted SILs sourced from Schedule B1 – Guideline on Investigation Levels for Soil and Groundwater, (NEPC 2013).

• A preliminary in-situ waste classification prepared for the surplus soils (BH1a, BH2a and BH5a) was classified as general solid waste.

• The site history, site observations, and laboratory results identified no areas of environmental concern on this site.

On the basis of the findings of this preliminary SCA, it is assessed that there is a low

potential risk from soil or groundwater contamination to human health or environment



2

on this site. No evidence of soil or groundwater contamination was identified which

would warrant further detailed site investigation or remediation in accordance with the

requirements of State Environmental Planning Policy No. 55 – Remediation of Land (SEPP 55).

The site is assessed to be suitable for its proposed ongoing commercial use, subject to

the implementation of the following recommendations:

Waste Classification Assessment – During construction works surplus soil requiring

offsite disposal must be assessed and classified prior to being transported to an

appropriately licenced landfill in accordance with the NSW EPA Waste Classification Guidelines 2014.

It is noted that the preliminary testing undertaken does not constitute a detailed waste classification for materials to be excavated from this site. Given the presence of imported fill material of unknown origin we recommend that further sampling and testing is undertaken to satisfy waste classification and/or respective NSW EPA approved resource recovery orders and exemptions.

Unexpected Finds Protocol – An unexpected fines protocol should be included as part of

the Construction Environment Management Plan or as a stand-alone document in the

event that potentially contaminated fill material or buried unexpected finds, such as

asbestos waste, are encountered during construction earthworks.

1. Introduction

D&N Geotechnical Pty Ltd were engaged by Queanbeyan-Palerang Regional Council

(Council) to undertake a preliminary Soil Contamination Assessment (SCA) of Councils

proposed headquarters project on part of Lot 2 DP1179998, see Figure 1, the site. Council

in email of 5 November 2019 requested that an interim waste classification also be

undertaken in the location of proposed basement carpark. Two additional shallow

boreholes (~3mbgs) were developed and soil samples collected from the basement

carpark1.

D&N Geotechnical asked Ballpark Environmental Pty Ltd to review the laboratory results

from soil and groundwater samples and to prepare this preliminary SCA report.

D&N Geotechnical previously completed a geotechnical investigation on this site in

June 2019. Opus (2017) had also completed a geotechnical investigation and a

preliminary site investigation (PSI) for the adjoining Lot 5 to the west of the site, see

Figure 2. Based on a review of the previous investigation reports the following points

were noted:

• Hydrocarbons exceeding the ecological screening level (ESL) for F2 C10-C16 were

reported in BH4: 6.5m in the Opus report in the adjoining Lot 5. The borehole was

approximately 70m west of the current site boundary.

• The hydrocarbons were observed within the Unit 2b Alluvium within Lot 5. This

geological unit was logged by D&N Geotechnical at depths ranging from 3.5m to

11m below ground surface (bgs) within the site.

• Only 2 soil samples were analysed within the Unit 2b Alluvium during the Opus PSI

(BH4: 6.0m and 6.5m). At the time no soil samples were collected and analysed at

the depth of groundwater on Lot 5 (~7mbgs).

• Groundwater inflows were recorded between 7.1m and 7.5mbgs during drilling

works undertaken by D&N Geotechnical within the site. Standing water levels

(SWLs) were measured on the 5 June 2019 by D&N field staff for 2 existing

groundwater monitoring wells within Lot 5. The SWLs were recorded at 7.2m

(BH02) and 7.4mbgs (BH07).

• No hydrocarbon odours were observed during D&N’s geotechnical field

investigation in June 2019.

The purpose of the preliminary SCA was to assess soils in the Unit 2b Alluvium to assess

if potentially there is a hydrocarbon smear zone present at the groundwater SWL level

on this site.

The findings from the preliminary SCA soil and groundwater investigation aims to

provide Council with information required to assess if further detailed site

investigation, to assess the vertical and lateral extent of contamination, is necessary.

1 Note. Council proposes to also develop an underground carpark on the adjoining Lot 5. The scope of work for this preliminary SCA and interim waste classification assessment was limited to Lot 2 and did not include an assessment of conditions on Lot 5.

The preliminary SCA was undertaken in general accordance with the proposal prepared

by D&N Geotechnical (Ref: C-0259.00-P3, dated 30 October 2019) and email dated 5

November 2019 for the additional interim waste classification assessment.

2. Objective and Scope of Works



Investigation.

The scope of works carried out to meet the above objective is summarised below.

• D&N Geotechnical mobilised a drilling rig to site on Thursday 7 and Friday 8

November 2019 for the site investigation. A service locator was engaged to scan

and identified all services within the site and clear borehole locations prior to

commencement of drilling works.

• A total of 5 boreholes were drilled on the site for the preliminary SCA. Two

boreholes (BH1a, BH4a) were drilled to a depth of 9m bgs and borehole BH3a to a

depth of 10mbgs. Two boreholes (BH2a and BH5a) were drilled to a target depth of

3mbgs on the location of a proposed basement carpark. Discrete soil samples were

collected directly from the drill rig auger at regular intervals to screen for the

presence of petroleum hydrocarbons using a Photo-Ionisation detector (PID). The

PID screening results are shown on the logs provided in Appendix A.

• Additional soil samples were collected from three boreholes (BH1a, BH2a and BH5a)

at the location of a proposed basement carpark on Lot 5 for the purpose of

preparing an interim waste classification by chemical assessment.

• Installation of a groundwater monitoring well within BH1a on the site. A round of

groundwater sampling from this monitoring well was undertaken on the 8

November.

• For this investigation soils within a potential smear zone at the intersection with

the groundwater table (ranging from ~7m to ~9mbgs) were targeted using

continuous standard penetration test (SPT) sampler from depths of 7mbgs to end

of the borehole.

• Laboratory analysis of selected soil and groundwater samples.

• Preparation of this preliminary SCA report.

The following sections of this preliminary SCA report presents the information collected and findings for the site.

Queanbeyan River is closest permanent waterway and is located approximately ~ 260m down gradient to the east of the site.

3.1. Geology, Hydrogeology & Hydrology

The 1:100,000 scale Geological Map of Canberra, Queanbeyan and surrounds (Sheet 8727, 1st edition, 1992), infers the site is underlain by middle to late Ordovician bedrock of the Pittman Formation; described as comprising interbedded sandstone, siltstone, shale and minor black shale, chert and impure calcareous sandstone.

3.1.1. Subsurface Conditions

The geotechnical profile encountered and identified during the D&N Geotechnical investigation undertaken for the site in July 2019, comprised fill2 consisting of sandy gravel with traces of plastic, terracotta and concrete debris to a depth of approximately 2mbgs, overlying variable Quaternary Alluvium to a maximum depth of 11.5mbgs, underlain by sandstone bedrock.

Based on the findings of the borehole investigation, Ballpark has broadly inferred a similar subsurface profile into generalised geotechnical units for this report for the depth of drilling undertaken during this investigation, which is summarised in Table 2.

2 Note. During site investigation no evidence of asbestos debris was observed in excavated soils. It is possible that asbestos waste may be present mixed with building waste and it is recommended that an unexpected finds protocol be prepared and followed during proposed construction works on this site.

3.1.2. Groundwater Conditions

Groundwater inflow was observed during auger drilling at depths of between about 6.6m and 7m.

Groundwater standing water level (SWL) was measured in the groundwater monitoring well installed in BH1a on 8 November 2019 at 7.1m below ground surface (bgs).

The groundwater inflows observed during the D&N Geotechnical investigation were observed marginally deeper at depths ranging from 7.1m to 7.5mbgs. In July 2019 the recorded the SWL from the 2 monitoring wells in the adjacent site to the west at 7.2mbgs (BH07) and 7.4mbgs (BH02).

4. Assessment Criteria

Assessment criteria for soils and groundwater were selected for relevance to the proposed future commercial use of this site.

The criteria discussed below are intended to apply as Tier 1 risk assessment criteria based on certain site-specific characteristics. Where concentrations of a contaminant exceed the adopted assessment criteria, then further consideration of the specific



7

exposure pathway is required which may warrant further investigation, assessment or the development of a strategy to mitigate the potential risks identified.

4.1. Health and Ecological Investigation Levels (Soils)

Health and ecological investigation and screening levels for soil presented in Schedule B1 of the ASC NEPM are generally used in NSW when selecting investigation levels for chemical contaminants in soil, (NEPC 2013).

Health and ecological investigation and screening levels are applicable to the first stage (Tier 1) of site assessment and are used to assist in the iterative development of a Conceptual Site Model (CSM).

Health Investigation LeveIs (HILs) are applicable for assessing human health risk via relevant exposure pathways. HILs were developed for a broad range of metals and organic substances. These are generic to all soil types in Australia and apply generally to a depth of 3m below the soil surface for residential sites. For other land uses no specific guidance is provided on depth of application and site-specific conditions are to be used to determine the depth to which HILs apply. For the purpose of this preliminary SCA the HILs are applied to the likely maximum depth of soil disturbance from surface to 3mbgs.

Ecological Investigation Levels (EILs) are associated with selected metals and organic compounds and have been developed for assessing risk to terrestrial ecosystems under residential, open space and commercial/industrial land use scenarios. They apply to the top 2m of accessible soil, which corresponds to the root zone and habitation zone of many plant species.

Ecological Screening Levels (ESLs) are provided in the ASC NEPM for petroleum hydrocarbons in soil to provide Tier 1 ESLs for; benzene, toluene, ethylbenzene, xylene (BTEX) compounds, benzo(a)pyrene and F1 (C6-C10) and F2 (>C10-C16) total petroleum hydrocarbon (TPH) fractions. Similar to EILs the application of ESLs is from the ground surface to a depth of 2m, which generally corresponds with the root zone and habitation zone of plant species in temperate Australia. This site is assessed to have limited ecological value based on its location within an urban central business district. The development will involve construction of buildings with basement carparks, extensive paved surfaces and roadways. Therefore, EILs and ESLs were not assessed for this preliminary SCA report and are not considered further.

Health screening levels (HSLs) have been developed for selected petroleum compounds and fractions and are applicable to assessing human health risk via inhalation after vapour intrusion into indoor air and direct contact with soil and groundwater. These HSLs depend on general soil type (sand, silt and clay mixture), building configurations and land use scenarios.

4.2. Management Limits

In accordance with section 2.9 of Schedule B1 of the ASC NEPM, consideration of Management Limits for petroleum hydrocarbons has been included to assess the potential for accumulation of explosive vapours, the potential risk to buried infrastructure, or the formation of phase separated hydrocarbons (PSH). Management limits for commercial/industrial use are considered relevant for this site and are shown in Table LR2.



8

4.3. Adopted SILs & GILs

The ASC NEPM presents health investigation levels for different land uses (e.g. commercial/industrial, residential, recreational etc.) as well as ecological investigation levels.

As the planned future use for land within this area of the site is Council premises within an urban setting, we have adopted the guideline criteria for commercial/industrial use as appropriate soil investigation levels (SILs) and groundwater investigation levels (GILs) for the respective contaminants of potential concern (CoPC).

In summary the following ASC NEPM guideline values are adopted as SILs:

• Health investigation level (HIL) for Commercial/Industrial D (see Table 1A(1) HIL A)

• Soil HSLs for vapour intrusion of sandy soils for Commercial/Industrial (see Table 1A(3) HSL D)

• Management Limits for TRH fractions F1-F4 in sandy (coarse) soil for Commercial/Industrial (see Table 1 B(7))

The adopted SILs are presented in the attached Table LR2 with a summary of the laboratory results.

We have adopted the following ASC NEPM guideline values as GILs, see Table LR3:

• Groundwater investigation levels (GILs) for fresh waters (see Table 1C)

• Groundwaters HSL for vapour intrusion (see Table 1A(4)

4.4. Waste Classification

To prepare the interim waste classification of the in-situ soils at the location of the proposed basement carpark on this site selected soil samples were analysed, and the laboratory results compared with the contaminant threshold values (CT1) provide in Table 1 of the NSW EPA (2014) Waste Classification Guidelines Part 1: Classifying Waste.

5. Conceptual Site Model

A conceptual site model (CSM) is a representation of site related information regarding contamination sources, receptors and exposure pathways between those sources and receptors and is based on each of the elements defined in the ASC NEPM.

Based on the desktop review of available reports from previous investigations the known or suspected potential sources of soil and groundwater contamination on this site include:

• Imported fill material located at varying depths up to ~2mbgs on this site. The origins of the fill material are not known and may contain CoPC.

• Groundwater contamination from leaking underground fuel tanks or fuel spills from a nearby service station located upgradient of this site on Lowe Street.

Each of the above are identified as potential Areas of Environmental Concern (AEC) and Table 4 discusses the plausible pollutant linkages identified between the AEC and any nearby sensitive receptors.

6. Data Quality Objectives

Data quality objectives (DQOs) are developed using a seven-step process and are used

to define the type, quantity and quality of data needed to inform decisions relating to

the environmental condition of a site, see section 18 (Appendix B) of Schedule B2

Guideline on Site Characterisation of NEPC (2013).

DQOs were developed for this preliminary SCA report as shown in Table 5.

Table 5: Data Quality Objectives

DQO Step Description

1. State the problemThe objective of the preliminary SCA is to provide a preliminary

assessment of soil and groundwater contamination and, if required,

provide a basis for a more Detailed Site Investigation.

The main problems are:

• Has the groundwater beneath the site been contaminated by loss

of petroleum hydrocarbons from a nearby service station?

• How many soil bores and groundwater monitoring wells should

be drilled and where?

• Are there access restrictions present that may affect the location

of soil bores and the groundwater monitoring well and the

method(s) used for drilling?

• To what depths should the soil bores and groundwater

monitoring well be drilled/installed?

• At what depth should soil samples be collected?

• What are the contaminants of potential concern for soils and

groundwater on this site?

2. Identify the decision

Potential soil and groundwater contamination issues need to be assessed prior to planned commercial development proceeding on this site.

Is this site suitable for its intended ongoing commercial use?

3. Identify inputs to the decision

The primary inputs to assessing the above include:

• Information gathered from a review of previous investigations

undertaken on this site and the adjoining property to the west.

• Field observations, PID screening results and soil/groundwater

laboratory results.

• Relevant legislation and regulatory guidelines.



12

DQO Step Description

4. Define the boundaries of the study

The investigation area is defined by the boundaries of the site, as shown in Figure 1. It includes part of Lot 2 DP1179998, 257 Crawford Street, Queanbeyan NSW.

The vertical boundary for the study is from the soil surface to the depth of underlying groundwater at this site of about ~7mbgs.

The temporal boundary is the date of the preliminary SCA investigation on 8 November 2019.

5. Develop a decision rule

The decision rule for soil and groundwater for each chemical/layer to

assess the suitability of the site will be as follows:

• QA/QC assessment indicates that the data is usable;

• Where contaminant concentrations for each sample are below the

adopted investigation / screening levels, then no further

assessment is required with respect to that

contaminant/media/area; and

• Where contaminant concentrations are reported to exceed one or

more adopted investigation / screening levels, then additional

investigation or site-specific risk assessment may be required.

Remediation of the site would be recommended where the risk

has been shown to be unacceptable.

6. Acceptable limits on decision error

There are two main sources of false results which may cause decision

errors:

• Sampling errors, which occur when the samples collected are not

representative of the conditions within the investigation area; and

• Measurement errors, which occur during sample collection,

handling, preparation, analysis and data reduction.

False results may lead the decision maker to make the following

errors:

• Type I: deciding that the soil and/or groundwater is not

contaminated and, therefore, the site is suitable for ongoing

commercial use when the reverse is true; and

• Type II: deciding that the soil and/or groundwater is contaminated

and, therefore, the site is not suitable for commercial use when the

reverse is true.

An assessment will be made as to the likelihood of a Type I decision

error being made based on the results of a QA/QC assessment and the

closeness of the data to assessment criteria. Additionally, statistical

methods may be used, where applicable, such as 95% Upper

Confidence Limit (UCL) calculations. The investigation levels for

assessment are nominated in section 4. A Type II error would result in

additional investigation which almost certainly would allow correction

of that error.

7. Optimise the design for obtaining data

Based on the previous Steps 1 to 6 of the DQO process, the optimal design for obtaining the required data is presented in section 7 Sampling and Analysis Plan.



13

7. Sampling and Analysis Plan

A Sampling and Analysis Quality Plan (SAQP) was developed and implemented for the preliminary SCA based on the investigation DQOs, see section 6. The preliminary SCA sampling plan included:

• Drilling of 5 boreholes within the site and the collection and analyses of 17 soil samples and 1 groundwater sample from within the site.

• Two duplicate and one triplicate soil samples were collected for quality assurance purposes in accordance with Australian Standards (AS4482:2005).

Selected samples were submitted for laboratory analysis for the following contaminants of potential concern (CoPC) in soil and groundwater as summarised in Table 6.

7.1. Soil Sampling Methodology

The preliminary SCA works followed the soil and groundwater sampling methodology outlined in Table 7 & 8, respectively.

Table 7: Soil Sampling Methodology

Activity Detail / Comments

Underground Services Dial-Before-You-Dig (DBYD) service plans for the site and

immediately surrounding area were obtained and reviewed prior to

commencement of intrusive investigation works.

A service locator was engaged to scan and identified all services

within the site prior to commencement of the drilling program.

Borehole Drilling Program

Drilling work was undertaken on 7 and 8 November 2019 by GE

Drilling, a licenced drilling contractor.

A total of 5 boreholes were drilled using solid flight augers at

selected areas across the site. Three boreholes were drilled to a

maximum depth of 10m below surface targeting the soils around the

groundwater level.

The remaining two boreholes were drilling to 3m bgs targeting the

proposed underground carpark in the southern portion of the site.

The deeper BH1 was also in the proposed basement carpark and was

sampled in the upper soil profile.

Field borehole logs were prepared for each of the 5 boreholes and

are presented in Appendix A.

Soil Screening and

Sample Collection

Preliminary SCA

• Samples were collected for screening purposes directly from the

auger in the upper 6m of the soil profile in boreholes BH1, BH2

and BH3. These samples were screened in the field using a

calibrated PID to assess the potential presence of ionisable

volatile organic compounds (VOC). The PID readings are shown

on the field borehole logs, see Appendix A.

• SPT sampling was undertaken continually from around the

groundwater level at depths of 7-7.45m, 7.5-7.95m, 8-8.45m and

8.5-8.95m.

Interim Waste Classification Assessment

• Soil samples from were collected directly from the auger at

depths of 0.5m, 1m, 2m and 3m bgs in boreholes BH1, BH4 and

BH5. These samples were also screened with the PID and

readings are shown on the field borehole logs, see Appendix A.

Duplicate and triplicate soil samples were also collected for quality

assurance purposes in accordance with Australian Standards

(AS4482).



16


Sample Handling & Transportation

A clean pair of disposable nitrile gloves was used to collect each

sample. Soil samples were placed into laboratory prepared and

supplied glass jars, fitted with Teflon lined seals to limit possible

volatile loss. Sample jars were filled to minimise headspace.

Separate samples for soil screening were collected and placed in a

sealed labelled zip lock bag.

The soil samples were placed into ice chilled coolers and dispatched to a National Association of Testing Authorities (NATA) accredited laboratories (Eurofins MGT in Sydney and Melbourne were the primary and secondary laboratories) for analysis under chain of custody (CoC) control. CoC’s are included with the laboratory certificates in Appendix B.

Decontamination of sampling equipment

Multi-use sampling equipment, including solid flight augers and a

SPT sampler, were decontaminated by brush scrubbing with Decon

90™ solution and rinsed with clean potable water between

investigation locations.

A wash blank sample was collected following completion of the field

investigation and analysed by the laboratory.

QA/QC Samples To measure the accuracy and precision of the data generated by the

field and laboratory procedures for this assessment, additional

samples were collected and analysed the following quality

assurance / quality control (QA/QC) samples:

• Two intra-laboratory duplicate soil samples (QC01 & QC02)

• One inter-laboratory triplicate soil sample (QC02)

• A trip spike and trip blank were also included with the soil

samples and analysed by the laboratory.

7.2. Groundwater Well Details & Sampling Methodology

Details of the monitoring well construction and groundwater sampling methodology are provided in Table 8.

Table 8: Monitoring Well Construction and Groundwater Sampling Methodology


Well Construction & Development

A single groundwater monitoring well was installed in BH01. The

well was constructed using a 50mm diameter PVC pipe. A 3m length

of slotted screen was installed from the base of the borehole (8m) to

5m, with the remaining lengths solid PVC to the surface.

The well annulus was backfilled with clean graded sand to

approximately 1m above the screen level and then sealed with a

bentonite plug approximately0.5m thickness. A flush fitting gatic

cover was concreted in place to protect the well cap.



17


The well was developed using a dedicated disposable bailer

following completion of the groundwater well installation on the 7

November 2019.

Well GaugingThe monitoring well was gauged prior to sampling on 8 November

2019 using an oil/water Interface Probe to record the depth to

groundwater and the presence of Non-Aqueous Phase Liquid

(NAPL). No NAPL was detected in the wells.

Groundwater sampling

method

The groundwater sample was collected using a new dedicated

disposable bailer and a clean pair of disposable nitrile gloves.

The groundwater sample was immediately placed into laboratory

supplied bottles with appropriate preservatives and placed into a

chilled cooler.

Groundwater samples were dispatched to National Association of

Testing Authorities (NATA) accredited laboratories (Eurofins MGT in

Sydney and Melbourne were the primary and secondary

laboratories) for analysis under chain of custody (CoC) control. CoC’s

are included with the laboratory certificates in Appendix B.

Decontamination of

sampling equipment

A dedicated, single use disposable sampling equipment was used to

collect the sample from the monitoring well which does not require

decontamination.

QA/QC SamplesThe QA/QC sampling undertaken for this investigation were

discussed in Table 7 above under the soil sampling methodology.

8. Data Validation Assessment

8.1. Fieldwork Quality Control

The field quality control was generally in accordance with the DQOs, see section 6, and included the following elements.

• Sampling was performed by a qualified and experienced engineering geologist from D&N Geotechnical. Soil and groundwater samples were collected in accordance with NSW EPA approved guidelines and current industry practice.

• Collection and analysis of two blind duplicate (intra-laboratory) and one blind triplicate (inter-laboratory) soil sample, see Table LR1.

• Samples (as designated on the chain of custody form) were transported in insulated containers to Eurofins mgt, NATA accredited laboratory for analysis. A copy of the chain of custody form is provided in Appendix B.

8.2. Laboratory Quality Assurance / Quality Control (QA/QC)

An assessment of QA/QC is provided below which assesses; data completeness, comparability, representativeness, precision, and accuracy based on field and laboratory considerations and processes for assessment of data quality, see section 19 (Appendix C) of Schedule B2 Guideline on Site Characterisation of ASC NEPM.



18

Soil samples were transported under chain of custody conditions in an insulated container to Eurofins MGT laboratory in Sydney and Melbourne which is NATA accredited for the analyses performed. A copy of the chain of custody is included with the laboratory data provided in Appendix B.

The laboratory conducted internal quality control using laboratory duplicates, spikes and

method blanks. The results are shown with the laboratory report sheets in Appendix B.

Analytical methods used for the laboratory testing are also indicated on the laboratory

report sheets. The results of laboratory quality control testing are assessed to be within

acceptable limits.

Additional soil samples were collected for QA/QC purposes including 2 duplicate and 1

triplicate sample, which were submitted for analysis. Reported exceedances of the

relative percentage difference (RPD) 50% control limits was found in triplicate pair BH5;

0.5m / QC02 reporting an RPD value of 67% for arsenic. The RPD exceedances are

considered to be due to the heterogeneous nature of metals in the soil. A wash blank

and trip spike/blank were also analysed by the laboratory.

Based on the results it is considered that the field and laboratory methods are

appropriate, and that the data obtained is usable and considered to reasonably

represent the concentrations at the sampling points at the time of sampling. Overall, it is

assessed that the results are acceptable for the purposes of this investigation.

9. Laboratory Analysis

Samples were analysed by Eurofins MGT laboratories in Sydney (primary laboratory), and

Melbourne (secondary laboratory). Both laboratories are NATA accredited for the

analytes selected.

Selected soil samples and the groundwater sample were submitted for laboratory

analysis for a suite of CoPC as summarised in Table 6. Soil samples for the preliminary

SCA were selected to characterise the soils around the groundwater table within the

site. The interim waste classification assessment was targeted in the upper 3m of the

soil profile with the extent of the proposed basement carpark.

9.1. Field Screening

Soil samples were screened for presence of volatile hydrocarbons using a PID. The PID readings ranged between 0.1 ppm and 20.9 ppm (BH4 (0.5m)). Individual PID readings are reported on the logs for the boreholes provided in Appendix A.

9.2. Results

9.2.1. Soils

The laboratory test results for soil samples are summarised in Table LR2 and laboratory certificates of analysis are present in Appendix B. Comparison of soil concentrations to the adopted SILs discussed in section 4.3 and provided in Table LR2 is as follows:

• Concentrations of metals were below the adopted investigation levels or the laboratory’s LOR in the samples analysed.



19

• Concentrations of TRH were below the adopted investigation levels or the laboratory’s LOR in the samples analysed. Hydrocarbons were reported in BH2a: 1m collected from the existing fill material onsite. Reporting concentrations of 110 mg/kg (TRH C16-C34) and 130 mg/kg (TRH >C34-C40), however well below the adopted SILs of 1,700 mg/kg and 3,300 mg/kg, respectively.

• Concentrations of BTEX were below the adopted investigation levels and the laboratory’s LOR in the samples analysed.

9.2.2. Groundwater

The laboratory test results for groundwater monitoring event on 8 November 2019 are summarised in Table LR3 and laboratory certificates of analysis are present in Appendix B. Comparison of groundwater concentrations in MW1 to the adopted GILs discussed in section 4.3 and provided in Table LR3 is as follows:

• Concentrations of copper exceeded the adopted GIL of 1.4 μg/L, reporting concentrations of 2 μg/L.

• Concentrations (250 μg/L) of TRH C6-C10 (F1) were reported, however below the adopted GIL of 6,000 μg/L.

• Toluene (6 μg/L) was reported above the LOR.

9.2.3. Interim Waste Classification Assessment

The laboratory test results for soil samples are summarised in Table LR4 and laboratory certificates of analysis are present in Appendix B. Comparison of soil concentrations to the acceptance criteria discussed in section 4.4 and provided in Table LR4 is as follows:

To assess the preliminary waste classification of the in-situ soils within the site the laboratory test results were compared contaminant threshold values (CT1) provided in Table 1 of the NSW EPA (2014) Waste Classification Guidelines.

The following points are noted from these results:

• Concentrations of metals were below the CT1 or the laboratory’s limit of reporting (LOR).

• Concentrations of TRH and BTEX were below the CT1 or the laboratory’s LOR in the samples analysed.

Based on the laboratory results for the surplus soil samples analysed from boreholes; BH1a, BH2a and BH5a the imported fill material and underlying Unit 2A alluvium soils to be excavated from the proposed basement carpark, to a depth of 3mbgs, are assessed to have an interim waste classification as general solid waste.



20

10. Conclusions

The preliminary SCA was undertaken to assess if soils and groundwater located in the

Unit 2b Alluvium at the depth of the groundwater table (~7mbgs) on this site are

contaminated by petroleum hydrocarbons.

Previous investigations undertaken by Opus (2017) on the adjoining property, Lot 5,

about 70m to the west of this site had noted the presence of petroleum hydrocarbons at

a depth of 6.5mbgs. The petroleum hydrocarbons were logged from the Unit 2b

Alluvium which previous geotechnical investigations have logged to occur on Lot 5 and

this site from about 3.5m to 11mbgs.



Investigation.

In addition, Council has requested that an interim waste classification assessment also

be undertaken for surplus in-situ soils at the location of a proposed underground

carpark in the south of the site.

Based on review of available previous reports, site observations made during the SCA investigation, the soil and groundwater sampling, laboratory analysis, and data interpretation, we conclude that:

• The site of the proposed Queanbeyan-Palerang Regional Council administration and library building has previously been used for commercial purposes, as the former Council Chambers building, with no-evidence of former contaminating landuse or activities identified on this site.

• Site soils include imported fill material (surface to ~2.0mbgs) comprising sandy gravel with traces of plastic, terracotta and concrete debris, overlying natural silty clay alluvium (Unit 2A) soils which are overlying natural sandy gravel alluvium (Unit 2B) soils to depth of the investigation.

• Measured groundwater standing water levels from monitoring well MW1 installed on this site was 7.1mbgs.

• Field investigations identified no visual or olfactory indicators of soil contamination. Soil samples screened using a PID reported low readings with no evidence of volatile organic compounds.

• Laboratory results for analysis of selected soil samples and groundwater sample from MW1 for petroleum hydrocarbons (TRH/BTEX) and metals were below the adopted SILs sourced from Schedule B1 – Guideline on Investigation Levels for Soil and Groundwater, (NEPC 2013).

• A preliminary in-situ waste classification prepared for the surplus soils (BH1a, BH2a and BH5a) was classified as general solid waste.

• The site history, site observations, and laboratory results identified no areas of environmental concern on this site.

On the basis of the findings of this preliminary SCA, it is assessed that there is a low

potential risk from soil or groundwater contamination to human health or environment

on this site. No evidence of soil or groundwater contamination was identified which

would warrant further detailed site investigation or remediation in accordance with the



21

requirements of State Environmental Planning Policy No. 55 – Remediation of Land (SEPP 55).

The site is assessed to be suitable for its proposed ongoing commercial use, subject to

the implementation of the following recommendations:

Waste Classification Assessment – During construction works surplus soil requiring

offsite disposal must be assessed and classified prior to being transported to an

appropriately licenced landfill in accordance with the NSW EPA Waste Classification Guidelines 2014.

It is noted that the preliminary testing undertaken does not constitute a detailed waste classification for materials to be excavated from this site. Given the presence of imported fill material of unknown origin we recommend that further sampling and testing is undertaken to satisfy waste classification and/or respective NSW EPA approved resource recovery orders and exemptions.

Unexpected Finds Protocol – An unexpected fines protocol should be included as part of

the Construction Environment Management Plan or as a stand-alone document in the

event that potentially contaminated fill material or buried unexpected finds, such as

asbestos waste, are encountered during construction earthworks.

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.

WA DWER (n=10): PFBA, PFPeA, PFHxA, PFHpA, PFOA, PFBS, PFHxS, PFOS, 6:2 FTSA, 8:2 FTSA

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.

R20 This sample is a Trip Spike and therefore all results are reported as a percentage
