1 JBS July 2013 ATT: Jonathan Cawley Landscape Architect City of Botany Council 141 Coward St Mascot, NSW 2020 Via Environmental Assessment of Surface Soils at Grace Campbell Reserve Hillsdale Grace Campbell Cres, Hillsdale, NSW Dear Mr Cawley, 1. Introduction and Background JBS&G (NSW & WA) Pty Ltd trading as JBS&G was requested by City of Botany Council (Council) to undertake accessible surface soil investigations within Grace Campbell Reserve (the Park) located at Grace Campbell Cres Hillsdale. The investigations are understood to have been required following a request from the local community to assess accessible soils present on the Park for a range of potential environmental contaminants. 2. Objective The objective of the investigation was to identify if levels of soil contaminants as present within accessible surface soils on the Park pose a potential human health risk. 3. Site Identification Grace Campbell Reserve is located at Grace Campbell Cres Hillsdale. The Park is legally referred to as Lots 21 and 22 in Deposited Plan The Park is an irregularly shaped area, present over approximately 2750 m 2. The site location is shown on Figure 1 provided to Attachment 2 and the extent of the Park is shown on Figure 2 provided to Attachment 2. An inspection of the Park was completed by JBS&G Environmental Scientists on the 8 th July Features present on the Park included: A irregularly shaped delineated area present in the central and eastern portion of the site consisting of a bark / mulch ground cover and including items of play equipment (i.e. swings, slides etc) referred to as a playground throughout the remainder of this report; A paved area present at the western portion of the site which consist of a half basketball court and a smaller paved area adjoining a brick wall; Grassed level area over the remainder of the site with some large trees and park benches present throughout; and A small landscaped / garden area as present at the south-western corner of the site.

2 Surrounding land-uses have been identified as: North A Sydney Water controlled easement is present adjoining the northern boundary of the Park. This consists of a grassed area of varying elevation; East A residential unit / apartment block is present adjoining the eastern boundary of the Park; South Grace Campbell Cres is present adjoining the southern boundary of the Park. Further residential areas consisting of detached dwellings and apartment / unit block developments are located on the southern side of Grace Campbell Cres; and West A residential property consisting of a detached dwelling is located adjoining the western boundary of the Park. 4. Conceptual Site Model National Environment Protection (Assessment of Site Contamination) Measure, NEPC, 1999 (as amended 2013, NEPC 1999) identifies a conceptual site model (CSM) as a representation of site related information regarding contamination sources, receptors and exposure pathways between those sources and receptors. The development of a CSM is an essential part of all site assessments. NEPC (1999) identified the essential elements of a CSM as including: 2 Known and potential sources of contamination and contaminants of concern including the mechanism(s) of contamination; Potentially affected media (soil, sediment, groundwater, surface water, indoor and ambient air); Human and ecological receptors; Potential and complete exposure pathways; and Any potential preferential pathways for vapour migration (if potential for vapours identified). Each of these elements is discussed following. 4.1 Source of Contamination Potential sources of contamination on the Park site have been identified as: Potential lead impacts as associated with flaking lead paint as potentially used on historical structures on and in proximity of the Park; and/or Potential use of contaminated fill materials as associated with materials potentially generated by historical industrial activities located in proximity of the Park (i.e. Botany Industrial Area) and transported to the site for use as fill; and/or Potential historical uncontrolled dumping / waste discharge within the area of the Park; and/or Potential historical use of pesticides to control pests / weeds on the Park surface; and/or Potential migration of contaminants through groundwater onto the Park. A number of potential contaminants have been identified with these potential contamination sources including: Heavy metals; Volatile organic compounds including monocyclic aromatic hydrocarbons, halogenated aliphatic hydrocarbons and halogenated aromatic hydrocarbons; Semi-volatile organic compounds including chlorinated benzenes, phenols, polycyclic aromatic hydrocarbons, organochlorine pesticide and organophosphorus pesticides; Polychlorinated biphenyls; and

3 Asbestos. 4.2 Potentially Affected Media Potentially affected media have been identified as: Surface soils as potentially impacted by flaking lead paint, uncontrolled historical waste disposal and/or fill materials as sourced from off-site contaminated locations used to form the Park profile; Groundwater where surface soils have been impacted by potential mobile contaminants and contaminant migration has occurred to the extent of groundwater; and Ambient air where substantial concentrations of volatile contaminants are present in soils and volatilise into the overlying atmosphere or occur as particulates by fugitive dust emissions or otherwise from surface soils. No structures are present on the site, and there is no potential for accumulation of potential vapours emitted from impacted soils. 4.3 Human and Ecological Receptors and Exposure Pathways Table 1 summarises potential human receptors and associated exposure pathways for the Park. Table 1: Summary of Potential Human Exposures Receptor Media Potential Exposure Pathways Recreational (adult and child) Surface soils Inhalation (vapours) Inhalation (particulates) Oral Dermal Groundwater Inhalation (vapours) Sub-Surface Maintenance / Excavation (short duration) Soils over depth of excavation Inhalation (vapours) Inhalation (particulates) Oral Dermal Groundwater Inhalation (vapours) By review of Table 1, direct exposure to groundwater is not considered a complete exposure pathway as groundwater is anticipated to be present at a depth of 5 m below ground surface (bgs), which is well below the maximum anticipated depth of any future excavation on the site. Potential inhalation of vapours from potentially impacted groundwater is not considered a potentially significant exposure pathway. There are no buildings present on the Park and vapour accumulation will not occur. No beneficial use of groundwater (i.e. extraction) occurs on the Park. Soils which are located under pavement within the western portion of the Park will not pose a potential oral or dermal risk to normal site users. The occurrence of the pavement prevents direct exposure to these soils. Ecological receptors are restricted to flora and fauna populations on the site, and potential ecological receptors of groundwater, where migration of contaminants to groundwater has occurred. JBS inspections of the Park have not identified any evidence of potential vegetation stress. The nearest potential ecological receptors of groundwater are associated with Botany Bay located an approximate distance of 2km form the Park. 4.4 Preferential Pathways No potential preferential pathways have been identified on the Park site. 3

4 5. Data Quality Objectives Data Quality Objectives (DQOs) were established for the assessment works, as described in the following sections. 5.1 State the Problem The Hillsdale Community has identified a potential for surface soils on the Park to pose a potential human health risk. 5.2 Identify the Decision The following specific decisions were required to be made as part of these investigations: Do accessible surface soils on the Park pose a potential human health risk? Is the environmental data collected by this assessment sufficiently reliable to be used to assess the environmental status of accessible surface soils on the Park? 5.3 Identify Inputs to the Decision Inputs to the decisions are: Observations of surface soils across the Park site with particular regard to indicators of contamination (foreign materials, inclusions, asbestos containing materials, aesthetic indicators of contamination etc); Soil analysis data from samples of surface soils; Soil assessment criteria as protective of potential recreational land-uses; and Assessment of quality assurance / quality control (QA/QC) for the purposes of assessing data reliability. 5.4 Define the Study Boundaries The investigations are required only to assess potential health risks associated with human exposure to near surface soils within the Park. The lateral study boundary is defined as The Park, as defined as Lots 21 and 22 DP and excluding the paved areas where direct contact to soils is prevented. The vertical investigation boundary has been restricted to soils to a depth of 0.1m below the ground surface. The mulch / bark materials in the playground area have been excluded, with soils immediately underlying these materials assessed. The report for these works has been required to be issued to Council on the 10 th July Develop a Decision Rule The decision rules are outlined as follows: Are contaminants present in surface soils and pose a potentially unacceptable health risk to human users of the site; and Is the data reliable? 4

5 5.6 Specify Limits on Decision Errors Guidance for acceptable limits on decision errors is provided in AS Guide to the investigation and sampling of sites with potentially contaminated soil. Part 1: Non-volatile and semi-volatile compounds. Two types of error are nominated in AS including: A. Deciding that the site is acceptable when it actually is not; and B. Deciding that the site is unacceptable when it is. It is nominated in AS that limits should be set on these, with a 5% probability set for A type errors and 20% probability set for B type errors. The number of samples required to be collected to allow these limits on decision errors to be met is calculated using the following relationship: where: n = 6.2 x σ 2 / (C s μ) 2 n number of sample needed 6.2 factor derived from 0.05 A risk and 0.2 B risk σ estimated standard deviation of contaminants concentration (mg/kg or mg/l where a soil validation data set is formed with leachate data) μ average concentration of contaminant (mg/kg or mg/l where a soil validation data set is formed with leachate data) C s acceptable limit (mg/kg or mg/l where a soil validation data set is formed with leachate data) The limits on decision error have been assessed for each constituent reporting above laboratory detection limits to verify that a sufficient number of sample locations have been undertaken to facilitate decisions in accordance with the adopted limits on decision error. 5.7 Optimise the Design for Obtaining Data The following sampling plan has been implemented: Collection of surface soil samples from the playground area at the central and eastern portion of the site on a 5 m grid basis, resulting in the collection of a total of 15 soil samples (sample IDs SS25 to SS39 as shown on Figure 2 provided to Attachment 2); and Collection of surface samples from the remaining accessible Park area on a 10 m grid basis, resulting in the collection of 24 soil samples (sample IDs SS1 to SS24 as shown on Figure 2 provided to Attachment 2). All soil samples have been analysed for heavy metals (Sb, As, Ba, Cd, Co, Cr, Pb, Mn, Hg, Ni, Sn, Ti and Zn), volatile organic compounds (VOCs), semi volatile organic compounds (SVOCs), polychlorinated biphenyls (PCBs) and asbestos Soil Sampling Methodology Overlying bark and mulch was initially cleared in proximity of the sample locations prior to the collection of soil samples in the area of the playground. Soil samples were collected by the use of a sampling trowel by removal of surface soils to a typical depth of between 100 mm and 300 mm. During the collection of soil samples, features such as seepage, discolouration, staining, odours and other indications of contamination noted on field reporting sheets and are recorded on field notes provided as Attachment 5. Collected soil samples were immediately transferred to sample containers of appropriate composition (glass jars and plastic zip lock bags). Sample labels recorded JBS job number; sample identification number; and date and time of sampling. 5

6 Sample containers were transferred to a chilled ice box for sample preservation prior to and during shipment to the testing laboratory. A chain-of-custody form was completed and forwarded with the samples to the testing laboratory. Chain of custody forms are provided with laboratory documentation as Attachment 6. X-Ray Fluoresence (XRF) Spectrometer technology was also used to determine the composition of metals within soils during the collection of soil samples providing real time results. Results of XRF determinations are included in Table 4 provided to Attachment Laboratory Analyses NATA accredited laboratories were used for all laboratory analysis of all soil samples. 5.8 Assessment Criteria Assessment criteria have been derived for each constituent recorded above laboratory detection limits in the soils analysis data set as summarised in Table 2 following. Assessment criteria are provided for the protection of human health only.

The results of the field and laboratory QA/QC program indicates that the data obtained from the sampling and analysis can be considered appropriately accurate for the objectives of the assessment. However it should be noted that there is potential heterogeneity of contaminant distributions throughout fill based materials. 6. Results Observations during sampling have been recorded in field notes included in Attachment 5. Soil analysis data is summarised in Attachment 4. Sample locations are shown on Figure 2 in Attachment 2. Detailed laboratory reports and chain of custody documentation is presented in Attachment 6. An assessment of data quality has found that the data are of a suitable quality for the intended purposes (Attachment 3). 6.1 Field Observations Soils were found to consist of brown sandy soils, consistent with anticipated / typical top soil / upper soil characteristics for Botany / Hillsdale area. No potential indicators of contamination were identified apart from a small fragment of fibre cement sheet as identified as sample location SS23. Analysis of this fragment of sheet identified the presence of asbestos fibres. The fragment was removed from the site. No other potential asbestos containing materials were identified as present on the site surface. 6

7 6.2 Soil Results All soil results are summarised in soil data summary tables provided as Attachment 4. Heavy metals are the only constituents which have been recorded above laboratory detection limits. The maximum levels of each respective heavy metal constituent are well below the adopted site assessment criteria. Soil samples have been found to be free of asbestos fibres. 6.3 Compliance with Limits on Decision Error An assessment of the compliance of the environmental data sets with the limits on decision error has been undertaken for each of the constituents which have been recorded above detection limits. Sufficient samples have been collected, to allow decisions made with respect to the environmental data, that are within the adopted acceptable limits of decision error. 7. Conclusions Based on the findings of this investigation and subsequent to the limitations in Attachment 1, it has been found that surface soils as present on the Grace Campbell Reserve do not contain levels of environmental contaminants that would be considered to pose a potential health risk to Park users Should you have any queries or require further clarification, please feel free to contact the undersigned on or by msamuel@jbsg.com.au.

12 Attachment 3 Assessment of Quality Assurance/Quality Control The pre-determined data quality indicators (DQIs) established for the project are discussed below in relation to precision, accuracy, representativeness, comparability and completeness (Table A3.1). Precision - measures the reproducibility of measurements under a given set of conditions. The precision of the laboratory data and sampling techniques is assessed by calculating the Relative Percent Difference (RPD) of duplicate samples. Accuracy - measures the bias in a measurement system. The accuracy of the laboratory data that is generated during this study is a measure of the closeness of the analytical results obtained by a method to the true value. Accuracy is assessed by reference to the analytical results of laboratory control samples, laboratory spikes and analyses against reference standards. Representativeness expresses the degree which sample data accurately and precisely represents a characteristic of a population or an environmental condition. Representativeness is achieved by collecting samples on a representative basis across the site, and by using an adequate number of sample locations to characterise the site to the required accuracy. Comparability - expresses the confidence with which one data set can be compared with another. This is achieved through maintaining a level of consistency in techniques used to collect samples; ensuring analysing laboratories use consistent analysis techniques and reporting methods. Completeness is defined as the percentage of measurements made which are judged to be valid measurements. The completeness goal is set at there being sufficient valid data generated during the study.

RPDs where able to be calculated have been found to be generally acceptable, with a significant exceedance reported for lead in one duplicate pair and slightly elevated RPDs reported for barium. These RPD s are generally based on at least one analyte level close to detection limits. Further the soils are observed to be filled based and heterogeneous distribution of heavy metals can commonly occur in fill materials. Split Duplicates The rates of split duplicate sampling and analysis met the DQI for the soil samples. RPDs where able to be calculated have been found to be generally acceptable, with a significant exceedance reported for lead in one duplicate pair and slightly elevated RPDs reported for arsenic and barium. These RPD s are generally based on at least one analyte level close to detection limits. Further the soils are observed to be filled based and heterogeneous distribution of heavy metals can commonly occur in fill materials. Laboratory Duplicates Acceptable RPD s have been determined for laboratory duplicates apart from the RPD for mercury and barium in Sample SS11, nickel for sample SS31. RPDs for mercury and nickel were based on analyte levels very close to laboratory detection limits. RPD s can be elevated when base don low analyte levels due to 11

14 rounding of levels. The barium RPD is indicative of potential heterogeneous levels of heavy metals present in fill materials. Trip spike All trip spike results are found to be acceptable. Trip blank All trip blank results are found to be acceptable. Rinsate blank All rinsate blank results are found to be acceptable. Accuracy Surrogate Spikes Surrogate spikes have been reported for analysis of all constituents. Spikes have been found to be generally acceptable, apart from occurrences of under-recovery of surrogates in some semi-volatile analyses as base don phenolic surrogates. It is noted that under-recoveries of surrogates were within the laboratories NATA endorsed limits, and under-recovery of phenolic based surrogates is common in environmental samples. Noting compliance with laboratory NATA endorsed limits, surrogate recoveries are considered to have met the laboratories NATA endorsed limits and are considered acceptable. Matrix Spikes Noting the discussion of the laboratories NATA accredited limits, matrix spike analyses results have been found to be acceptable. Laboratory Control Samples Noting the discussion of the laboratories NATA accredited limits, laboratory control sample analyses results have been found to be acceptable. Representativeness Sampling appropriate for media and analytes Sampling has been undertaken by recovery of soil samples from SPT sampling tubes. These sampling methods are considered appropriate for the collection of undisturbed soil samples. The groundwater samples were all obtained using low flow peristaltic pump methods. Laboratory blanks All levels of analytes in laboratory blanks were below detection limits. Holding times All analyses have been undertaken within holding times. Comparability The laboratory (Envirolab Services) was NATA accredited for all methods. Experienced JBS personnel undertook all sampling in accordance with standard JBS sampling methods. Completeness Documentation All documentation is complete and correct. Frequency for QC Samples The frequency of analysis of all QC samples is considered appropriate. 12

15 Assessment of QA/QC The results of the field and laboratory QA/QC program indicates that the data obtained from the sampling and analysis can be considered appropriately accurate for the objectives of the assessment.
