1. Introduction

1.1 Background

Aqueous film-forming foams (AFFF) have been used for fire-fighting purposes around Australia

for decades. AFFF products historically used on some Department of Defence (Defence) sites

contain per- and poly-fluoroalkyl substances (PFAS) as active ingredients.

The historical use of AFFF has resulted in contamination of soil, groundwater, sediments and

surface water at many locations where AFFF has been used or stored. While the risks to human

health and the environment from PFAS are still the subject of much research, PFAS are highly

persistent in the environment, can bio-accumulate, and may be harmful to animal and human

health (US EPA, 2014).

Defence is in the process of investigating the potential for PFAS to be present on-site and off-

site in groundwater, surface water, soil and sediments at RAAF Base Holsworthy (the site) as

part of a process of prioritising any future investigations. As part of this, preliminary and limited

sampling and analysis of environmental media has been conducted to evaluate the potential for

the site to be a source of PFAS to off-site areas.

This investigation is intended to be a snapshot of the potential off-site presence of PFAS

only, and should be regarded as a preceding step to any future preliminary

investigations that would be conducted in accordance with the approaches specified by

the National Environmental Protection (Assessment of Site Contamination) Measure

(ASC NEPM).

1.2 Objective

The objective of the investigation was to test for the presence of PFAS in environmental media,

and to provide an indication of the potential for PFAS to have migrated off-site via surface water.

This was to assist Defence to meet its objective to facilitate the early identification of potential

exposure risks to off-site users of groundwater for the purpose of prioritising any future

investigations.

1.3 Scope

The scope of the investigation at RAAF Base Holsworthy comprised:

Preparation of a Sampling & Analysis Quality Plan (SAQP) outlining the sampling &

analysis scope, methodology and objectives.

Selection of five surface water/stormwater drainage locations that may indicate the

potential for PFAS to be present off-site via surface runoff and stormwater drainage.

Collection of samples from the five selected surface water locations.

Laboratory analysis of samples for a suite of PFAS and other parameters.

Evaluation and interpretation of results with respect to a set of screening levels specified

by Defence for PFAS, and other Nationally applicable criteria for other parameters.

1.4 Limitations

This report has been prepared by GHD for Jones Lang LaSalle and Department of Defence

(Defence) and may only be used and relied on by Jones Lang LaSalle and Department of

Defence for the purpose agreed between GHD and Jones Lang LaSalle and Department of

Defence as set out in section 1.2 of this report.

GHD otherwise disclaims responsibility to any person other than Jones Lang LaSalle and

Defence arising in connection with this report. GHD also excludes implied warranties and

conditions, to the extent legally permissible.

The services undertaken by GHD in connection with preparing this report were limited to those

specifically detailed in the report and are subject to the scope limitations set out in the report.

The opinions, conclusions and any recommendations in this report are based on conditions

encountered and information reviewed at the date of preparation of the report. GHD has no

responsibility or obligation to update this report to account for events or changes occurring

subsequent to the date that the report was prepared.

The opinions, conclusions and any recommendations in this report are based on assumptions

made by GHD listed in Section 1.5 and contained throughout this report. GHD disclaims liability

arising from any of the assumptions being incorrect.

GHD has prepared this report on the basis of information provided by Jones Lang LaSalle,

Department of Defence and others who provided information to GHD (including Government

authorities), which GHD has not independently verified or checked beyond the agreed scope of

work. GHD does not accept liability in connection with such unverified information, including

errors and omissions in the report which were caused by errors or omissions in that information.

The opinions, conclusions and any recommendations in this report are based on information

obtained from, and testing undertaken at or in connection with, specific sample points. Site

conditions at other parts of the site may be different from the site conditions found at the specific

sample points.

Investigations undertaken in respect of this report are constrained by the particular site

conditions, such as the location of buildings, services and vegetation. As a result, not all

relevant site features and conditions may have been identified in this report.

Site conditions (including the presence of hazardous substances and/or site contamination) may

change after the date of this Report. GHD does not accept responsibility arising from, or in

connection with, any change to the site conditions. GHD is also not responsible for updating this

report if the site conditions change.


1.5 Assumptions

Being preliminary in nature, the investigation outcomes are necessarily subject to a number of

limitations which are contained throughout the report. The key assumptions are listed below:

As the investigation is intended to precede any subsequent preliminary and detailed

investigation that would be in accordance with the ASC NEPM, no conceptual site models

have been used as a basis for design of the sampling and analysis plans for the

investigation.

Sampling was conducted at each location once, and as such the results of the

investigation represent a snapshot at one particular time and do not take into account

possible seasonal variations.

While consideration has been given to possible on-site sources of PFAS and the

sampling plan designed accordingly, no site history or other information was considered

in relation to other potential contaminants of concern.

The investigation focused on early identification of potential impacts to off-site users of

groundwater, rather than potential ecological impacts or impacts to human health arising

from the presence of PFAS in surface water.


2. Methodology

2.1 Sample locations

Details of the nature and number of sample locations for RAAF Base Holsworthy are contained

in Table 1. This includes information on proposed and actual sample locations.

Due to the inherent uncertainty associated with accessing bores owned by others at locations

on private property, all the bores that were identified for sampling could not be sampled as a

result of them being (a) un-locatable and presumed destroyed, or (b) locatable but unsuitable for

sampling due to their condition. Where this was the case, every effort was made to locate an

alternative location for sampling to bridge the data-gap. An additional surface water sampling

location was added to the sampling program in place of the groundwater bore that was not able

to be located.

The proposed and actual groundwater and surface water sampling locations are shown on

Figure 1.

Surface water sampling locations were selected with the aim of identifying areas of potential or

likely runoff from PFAS sources present on-site. This was based on (a) likely direction of surface

drainage from PFAS sources on-site, based on topography, (b) drainage lines originating from

or crossing through the site that were likely to receive drainage from PFAS sources on-site, (c)

drainage lines connecting with off-site surface water bodies, and (d) likely accessibility (e.g.

proximity to roads and access paths).

To protect the privacy of landowners who granted access to their properties for the purposes of

this project, no site addresses, names or co-ordinates are presented in this report.

Offsite HBK_SW003 Sampled, as per SAQP

Offsite HBK_SW005 Sampled surface water instead of GW1000098, as bore could not be found.

Offsite HBK_SW004 Sampled: moved slightly downstream due to safe site access.

Offsite HBK_SW002 Sampled: moved downstream due to restricted site access.

GW100098 Not sampled: unable to locate well, HBK_SW005 sampled instead.

GW108802 Removed from program, not required by Defence.



GW107001 Removed from program.

Notes: 1. RAAF Base Holsworthy - No on-site or off-site groundwater sample locations due to absence

of suitable bores - desktop and groundwater database reviews suggest low potential for groundwater abstraction off-site. On-site and off-site surface water samples retrieved from tributaries leading from potential PFAS sources.


2.2 Sampling Methodology

The sampling methodology was in accordance with:

ASC NEPM (as amended in 2013) Schedule B(2) Guideline on Site Characterisation

(ASC NEPM)

WA Department of Environment Regulation, Interim Guidelines on the Assessment and

Management of Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS), Contaminated

Sites Guidelines (DER, 2016)1

2.2.1 Surface water sampling

Surface water samples were collected directly from the water body from the embankment using

a long handled sampler, and were decanted directly to laboratory prepared sample bottles. Field

parameters (pH, EC, DO, temperature and redox potential) were measured at the time of

sampling using a calibrated water quality meter. A GPS location and sample depth were

recorded at each surface water sample location. Note that all samples were collected at surface

and therefore no depth measurements are provided in this report.

2.2.2 Sample handling and field QA/QC

Once collected, samples of all media were labelled and stored in ice chilled cooler boxes.

Samples were stored out of direct sunlight. Samples were dispatched the primary and

secondary laboratories under Chain of Custody (COC) documentation. Verified copies of the

chain of custody were retained.

Potential sources of false positive PFAS detections were minimised through adoption of the

recommended mitigation practices and alternative products and practices outlined in DER 2016.

The exception to this was the use of a detergent (Decon 90) to decontaminate the interface

probe as discussed above.

Quality Control and Quality Assurance samples were analysed for PFAS at the following rates:

(a) Intra-laboratory duplicates - one secondary sample for each five primary samples, (b) Inter-

laboratory duplicates - one secondary sample for each five primary samples, and (c) Trip blank

and rinsate blank samples - one of each per base. The rinsate blank samples were used to

assess any potential cross contamination from the only piece of equipment that will be reused in

each bore which was the interface meter.

2.3 Laboratory analysis

Surface water samples were analysed at two National Association of Testing Authorities (NATA)

accredited commercial laboratories as follows:

ALS Environmental – analysis of all primary samples

MGT Eurofins – analysis of all secondary samples

Primary and secondary samples were analysed for the parameters shown below in Table 2.

1 Relevant due to its specific applicability to the assessment of PFAS contamination, and in the absence of other similar

National or State specific guidance.

3. Adopted screening levels

The adopted screening levels have been selected on the basis of the project objective stated in

Section 1.2.

As such, the screening levels adopted for PFAS have been limited to those applicable to off-site

users of groundwater contained in Defence Contamination Directive Number 8 (Directive 8)

which are (a) ‘Human Health (Drinking Water)’ and (b) ‘Recreational Use’.

For the other (non-PFAS) parameters tested during the investigation the adopted screening

levels were in accordance with the ASC NEPM and have been referenced from the following:

NHMRC, National Water Quality Management Strategy, Australian Drinking Water

Guidelines 6, 2011 (ADWG 2011)

Guidelines for managing risk in recreational water (GMRRW) (NHMRC 2008)

either the laboratory LOR or the adopted screening levels.

4.4 Data Quality

High standards of data integrity and quality assurance and quality control (QA / QC) were

maintained throughout the task in accordance with the guidelines provided in the ASC NEPM

and the Australian Standard (AS 4482.1-2005) and included:

Use of appropriately qualified and trained staff

Preservation of samples with ice during transport from the field to the laboratory

Transportation of samples with accompanying chain of custody documentation

Compliance with sample holding times

Review of results for duplicate samples

Review of results for split samples

Review of internal analysis of laboratory duplicates, spikes and blanks

The results of the QA/QC program were reviewed and are considered to provide an acceptable

degree of confidence in the analytical program completed. Overall the analytical data set is

considered to be valid and acceptable for the purposes of this project.

General Comments

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

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

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

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

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

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

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

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

LOR = Limit of reporting

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

ø = ALS is not NATA accredited for these tests.

~ = Indicates an estimated value.

Key :

EN055: Ionic Balance out of acceptable limits for sample 3 due to analytes not quantified in this report.l

General Comments

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

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

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

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

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

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

LOR = Limit of reporting

RPD = Relative Percentage Difference

# = Indicates failed QC

Key :

Laboratory Duplicate (DUP) Report

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

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

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

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

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

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

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

This report is automatically generated by the ALS LIMS through interpretation of the ALS Quality Control Report and several Quality Assurance parameters measured by ALS. This automated

reporting highlights any non-conformances, facilitates faster and more accurate data validation and is designed to assist internal expert and external Auditor review. Many components of this

report contribute to the overall DQO assessment and reporting for guideline compliance.

Brief method summaries and references are also provided to assist in traceability.

Analysis Holding Time Compliance

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

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

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

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

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

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

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

Brief Method SummariesThe analytical procedures used by the Environmental Division have been developed from established internationally recognized procedures such as those published by the US EPA, APHA, AS and NEPM. In house

developed procedures are employed in the absence of documented standards or by client request. The following report provides brief descriptions of the analytical procedures employed for results reported in the

Certificate of Analysis. Sources from which ALS methods have been developed are provided within the Method Descriptions.

Analytical Methods Method DescriptionsMatrixMethod

In house: Referenced to APHA 2540C. A gravimetric procedure that determines the amount of `filterable` residue

in an aqueous sample. A well-mixed sample is filtered through a glass fibre filter (1.2um). The filtrate is

evaporated to dryness and dried to constant weight at 180+/-5C. This method is compliant with NEPM (2013)

Schedule B(3)

Total Dissolved Solids (High Level) EA015H WATER

In house: Referenced to APHA 2320 B This procedure determines alkalinity by automated measurement (e.g. PC

Titrate) using pH 4.5 for indicating the total alkalinity end-point. This method is compliant with NEPM (2013)

Schedule B(3)

Alkalinity by PC Titrator ED037-P WATER

In house: Referenced to APHA 4500-SO4. Dissolved sulfate is determined in a 0.45um filtered sample. Sulfate

ions are converted to a barium sulfate suspension in an acetic acid medium with barium chloride. Light

absorbance of the BaSO4 suspension is measured by a photometer and the SO4-2 concentration is determined

by comparison of the reading with a standard curve. This method is compliant with NEPM (2013) Schedule B(3)

Sulfate (Turbidimetric) as SO4 2- by

Discrete Analyser

ED041G WATER

In house: Referenced to APHA 4500 Cl - G.The thiocyanate ion is liberated from mercuric thiocyanate through

sequestration of mercury by the chloride ion to form non-ionised mercuric chloride.in the presence of ferric ions

the librated thiocynate forms highly-coloured ferric thiocynate which is measured at 480 nm APHA 21st edition

seal method 2 017-1-L april 2003

Chloride by Discrete Analyser ED045G WATER

In house: Referenced to APHA 3120 and 3125; USEPA SW 846 - 6010 and 6020; Cations are determined by

either ICP-AES or ICP-MS techniques. This method is compliant with NEPM (2013) Schedule B(3)

Sodium Adsorption Ratio is calculated from Ca, Mg and Na which determined by ALS in house method

QWI-EN/ED093F. This method is compliant with NEPM (2013) Schedule B(3)

Hardness parameters are calculated based on APHA 2340 B. This method is compliant with NEPM (2013)

Schedule B(3)

Major Cations - Dissolved ED093F WATER

In house: Referenced to APHA 3125; USEPA SW846 - 6020, ALS QWI-EN/EG020. Samples are 0.45µm filtered

prior to analysis. The ICPMS technique utilizes a highly efficient argon plasma to ionize selected elements. Ions

are then passed into a high vacuum mass spectrometer, which separates the analytes based on their distinct

mass to charge ratios prior to their measurement by a discrete dynode ion detector.

Dissolved Metals by ICP-MS - Suite A EG020A-F WATER

In house: Referenced to AS 3550, APHA 3112 Hg - B (Flow-injection (SnCl2)(Cold Vapour generation) AAS)

Samples are 0.45µm filtered prior to analysis. FIM-AAS is an automated flameless atomic absorption technique.

A bromate/bromide reagent is used to oxidise any organic mercury compounds in the filtered sample. The ionic

mercury is reduced online to atomic mercury vapour by SnCl2 which is then purged into a heated quartz cell.

Quantification is by comparing absorbance against a calibration curve. This method is compliant with NEPM

(2013) Schedule B(3)

Dissolved Mercury by FIMS EG035F WATER

In house: Referenced to APHA 1030F. This method is compliant with NEPM (2013) Schedule B(3)Ionic Balance by PCT DA and Turbi SO4

QC - Acceptance Criteria

QC Data General Comments

1. Laboratory QC results for Method Blanks, Duplicates, Matrix Spikes, and Laboratory Control Samples are included in this QC report where applicable. Additional QC data may be available on

request.

2. All soil results are reported on a dry basis, unless otherwise stated.

3. Actual LORs are matrix dependant. Quoted LORs may be raised where sample extracts are diluted due to interferences.

4. Results are uncorrected for matrix spikes or surrogate recoveries.

5. SVOC analysis on waters are performed on homogenised, unfiltered samples, unless noted otherwise.

6. Samples were analysed on an 'as received' basis. 7. 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 Sample

Receipt Advice.

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.

**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.

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.

Batch Duplicate A second piece of analysis from a sample outside of the clients batch of samples but run within the laboratory batch of analysis.

Batch SPIKE Spike recovery reported on a sample from outside of the clients batch of samples but run within the laboratory batch of analysis.

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 50-150%-Phenols & PFASs 20-130%

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.
