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,

surface water and infrastructure 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 Townsville (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 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.

This was to provide an indication of the potential for PFAS to have migrated off-site via

groundwater or surface water. This was to assist Defence to meet its objective of facilitating 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 Townsville comprised:

Selection of ten (10) existing groundwater monitoring wells, with an emphasis on wells

that may indicate the potential for PFAS to be present off-site.

Collection of samples from the 10 selected groundwater wells.

Selection of up to three locations for surface water/stormwater drainage and sediment

sampling at locations that may indicate potential for off-site presence of PFAS via surface

runoff and stormwater drainage.

Collection of up to three surface water and up to three sediment samples from the

selected 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.

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 basis for design of the sampling and analysis plans for the

investigation

Groundwater sample locations have been limited to existing investigation and abstraction

bores and therefore:

– The groundwater sampling locations were selected on the basis of accessibility and a

limited understanding of site and regional geology, hydrogeology and hydrology, and

potential sources of PFAS.


– Information on the construction and condition of groundwater investigation and

abstraction bores was limited to information contained in the State groundwater

database, therefore the suitability of the groundwater bore for providing a

representative sample of surrounding aquifer conditions cannot be confirmed.

Sampling has been 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 has been

considered in relation to other potential contaminants of concern.

The investigation is 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 presence of PFAS in surface water.


2. Methodology

2.1 Sample locations

Details of the nature and number of sample locations are contained in Table 1. This includes

information on proposed and actual sample locations.

Searches of the State groundwater database did not identify the presence of any off-site

groundwater monitoring wells considered suitable for fulfilling the project objective. Therefore,

established on-site groundwater wells (including many in close proximity to the site boundary)

were sampled instead to provide an indication of the potential for off-site contamination.

The groundwater sampling was complemented with surface water and sediment sampling within

drainage lines on Defence land near points of discharge from the site.

The proposed and actual groundwater and surface water / sediment sampling locations are

shown on Figure 1.

The groundwater sample locations were selected on the basis of (a) the presence of existing

bores and their suitability for sampling, and (b) their location with respect to potential PFAS

sources.

Surface water / stormwater and sediment 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 offsite 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.

2.2 Sampling methodology

2.2.1 Groundwater

The groundwater sampling methodology was in accordance with:

EPA Victoria Publication 668 Hydrogeological Assessments (Groundwater Quality)

Guidelines 20061

EPA Victoria Publication 669, Groundwater Sampling Guidelines 20001

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

EPA Victoria Publication IWRG 701, Sampling and analysis of waters, wastewaters, soils

and wastes 20091

Australian Standard (AS) 4482.1 Guide to the investigation and sampling of sites with

potentially contaminated soil

The following methodology was applied:

1. The well that was intended for sampling was positively identified. Any ambiguity was

resolved before proceeding. Where contaminated groundwater was suspected, wells with

the least potential to be contaminated were sampled first to minimise the risk of cross

contamination between samples.

2. The depth to groundwater in the well was measured by the use of an interface probe.

Prior to measuring, the bore cap was removed and the well head level was allowed to

stabilise before measurements were made. Depth measurements were referenced to the

top of well casing as an established datum. Where possible, depth measurements were

recorded to the nearest 1 mm. Repeat measurements were made at subsequent time

intervals so that equilibrium was attained if there was any doubt. Any field notes regarding

odour or other observations were recorded. Low flow sampling methodologies were used

to collect groundwater samples. The objective of this approach was to remove the

minimum amount of water to obtain representative aquifer samples. It relies on horizontal

flow from the aquifer directly into the pump, rather than dewatering of the well column

leading to inflow. This is verified through the careful monitoring of water level deflections

and by avoiding to the extent practicable the drawdown of the water in the well due to

pumping. The water level was left to stabilise to the standing level between each pump

cycle.

1 Considered ‘best industry practice’ and applicable to Federal land and jurisdictions outside Victoria


3. All reusable sampling equipment was decontaminated prior to and at completion of

sampling at each sample location. Contaminated or likely to be contaminated equipment,

instruments and other items were cleaned and / or sterilised before they were re-used.

The decontamination process comprised cleaning with Decon 90, a single rinse with tap

water, followed by a triple rinse with de-ionised water using a spray bottle. Only Teflon

free sampling equipment was used.

4. Since the method draws water from a discrete layer of the aquifer, the level of the pump

was recorded so that repetitive sampling could be undertaken at the same level of the

aquifer.

5. The pump was lowered carefully into the well and the hanging cable locked at the correct

position having regard to the depth to groundwater, the screened interval and the total

depth of the well. The well was allowed to stabilise to the initial SWL. Care was taken

when lowering sampling equipment into the well to avoid excessive disturbance and re-

suspension of sediment. The intake part of the sampling equipment was suspended

inside the well screen so as to minimise the volume of stagnant groundwater required to

be purged and intercept the inflowing groundwater from the target formation. The pump

cycle rate was set so that the water level returned to the initial SWL before the next pump

cycle.

6. Purging was conducted until the groundwater parameters had stabilised as noted above

and (where reasonable) a minimum of one bore volume had been removed. Parameter

measurements were recorded at regular intervals (i.e. every two to five minutes or every

two to five litres). A minimum of three readings were required to confirm stabilisation.

Descriptions of the visual and olfactory characteristics of the groundwater were recorded

each time a measurement was made and included details such as elapsed time, volume

purged, colour, turbidity, odour, sheen etc. All measured stabilisation parameters and

field observations were recorded on GHD’s standard purging and sampling field sheet pro

forma. The parameters were considered stable when three consecutive readings were

within: 0.05 for pH; 3% for EC; 10% for DO; 0.2 oC for temperature; and 10 mV for Eh.

Where drawdown had been observed, or parameters were unstable, a minimum of three

bore volumes was removed.

7. Once parameters had stabilised, a sample was collected directly from the low flow

sampler into laboratory prepared sampling container for each parameter. For all samples

analysed for PFAS only Teflon free containers were used. Sample containers included:

laboratory supplied HDPE bottles for PFAS analysis, and laboratory supplied analyte

specific vessels for analysis of other chemicals. Sample collection was undertaken so as

to minimise the entry of air into the sample by running the outflow from the sampling

device down the side of the container, rather than allowing it to cascade into the

container.

8. If, after prolonged purging the indicator parameters did not stabilise to within the specified

limits, the original well and gravel pack volume was estimated and at least three well

volumes of groundwater was purged. Whilst this was not the preferred approach, it

provided a contingency based on the assumption that purged water is acceptably

representative of formation water.

9. Low yielding wells that were purged dry were left to recover. Following recovery of

groundwater levels in the well, sampling proceeded on the assumption that the

groundwater represented inflow from the hydrostratigraphic unit screened by the well. In

this instance, measurement of stabilisation parameters proceeded as per the specified

procedure to provide a cross check and so that representative formation water was being

collected.


10. Once collected, groundwater samples were labelled and stored in ice chilled cooler

boxes. Samples were kept out of direct sunlight. Samples were dispatched to the primary

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

copies of the chain of custody were retained.

11. Low flow sampling generally provides low turbidity samples and the need for filtering may

be reduced or prevented. Where samples are turbid, they may contain suspended

particles with adsorbed contaminants. The need for filtering depended on individual wells

and the samples produced. The inclusion of these particles in the sample may result in

exchange between the adsorbed and dissolved phase leading to erroneous results.

Ideally, the samples were collected so that there was no need to filter, and filtration was

not used to compensate for inadequate sampling practice. If filtration was deemed

necessary, the sample was passed through a 0.45 um filter prior to collection in the

appropriate vessel. Sample containers for metals analysis were preserved with acid to

retain dissolved metals in solution. Acidified sample bottles were not used if samples

were not filtered in the field. This avoided stripping any adsorbed metals from the

remaining suspended particles.

12. Following use, the equipment was removed from the well. The pump was dismantled and

decontaminated together with any other equipment including hoses, water level meters

and flow cells. The decontamination process comprised cleaning as described above.

Only Teflon free sampling equipment was used. The pump bladder was replaced

between each sampling location to minimise the potential for failure and to minimise any

risk of cross contamination since the bladders are difficult to decontaminate.

13. Potentially contaminated purge water was collected and stored at an appropriate location

on-site in consultation with the Regional Environmental Officer (REO). Upon receipt of the

analytical results, GHD arranged for the purge water to be disposed of appropriately by a

liquid waste contractor licenced to receive the type of waste in accordance with

Queensland legislation and waste screening criteria.

2.2.2 Surface water and sediment sampling

The sampling methodology was in accordance with:

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

EPA Victoria Publication IWRG 701, Sampling and analysis of waters, wastewaters, soils

and wastes 2009

The following methodology was applied:

1. The location that was intended for sampling was identified and marked on a site plan with

reference to permanent features where possible.

2. Any reusable sampling equipment was decontaminated prior and at completion of

sampling at each sample location. Contaminated or likely to be contaminated equipment,

instruments and other items were cleaned and / or sterilised before re-use. The

decontamination process comprised cleaning with Decon 90, a single rinse with tap

water, followed by a triple rinse with de-ionised water using a spray bottle. Only Teflon

free sampling equipment was used.

3. 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.


4. Sediment samples were collected by the use of a sediment grab sampler and placed

immediately into Teflon free laboratory prepared jars.

5. Once collected, samples were labelled and stored in ice chilled cooler boxes. Samples

were kept out of direct sunlight. Sample were dispatched to the primary and secondary

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

custody were retained.

6. GPS coordinates were recorded for all surface water and sediment sampling locations.

7.

2.2.3 Sample handling and field QA/QC

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

Sample were dispatched to 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 10 primary samples, (b) Inter-

laboratory duplicates - one secondary sample for each 10 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

Sediment samples were analysed at ALS Environmental, a National Association of Testing

Authorities (NATA) accredited commercial laboratories. Groundwater and 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

SGS Environmental – analysis of all secondary samples

All samples were tested at standard laboratory detection limits and standard laboratory

turnaround times.


Primary and secondary (quality assurance) samples were tested for the following parameters:

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 sampling holding times

Review of results of 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.

Key :

EG005T (Total Metals by ICP-AES): Sample EB1611813-002 shows poor duplicate results due to sample heterogeneity. Confirmed by visual inspection.l

TDS by method EA-015 may bias high due to the presence of fine particulate matter, which may pass through the prescribed GF/C paper.l

EP231: Particular samples required dilution due to sample matrix . LOR values have been adjusted accordingly.l

PFOS and PFOA results are reported as an aggregate of linear and branched isomers.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.

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.

METHOD METHODOLOGY SUMMARY

METHOD SUMMARY

pH in Soil Sludge Sediment and Water: pH is measured electrometrically using a combination electrode (glass plus

reference electrode) and is calibrated against 3 buffers purchased commercially. For soils, an extract with water is

made at a ratio of 1:5 and the pH determined and reported on the extract. Reference APHA 4500-H+.

AN101

Total Dissolved Solids: A well-mixed filtered sample of known volume is evaporated to dryness at 180°C and the

residue weighed. Approximate methods for correlating chemical analysis with dissolved solids are available.

Reference APHA 2540 C.

AN113

This method is used to calculation the balance of major Anions and Cations in water samples and converts major

ion concentration to milliequivalents and then summed. Anions sum and Cation sum is calculated as a difference

and expressed as a percentage.

AN121

Alkalinity (and forms of) by Titration: The sample is titrated with standard acid to pH 8.3 (P titre) and pH 4.5 (T titre)

and permanent and/or total alkalinity calculated. The results are expressed as equivalents of calcium carbonate or

recalculated as bicarbonate, carbonate and hydroxide. Reference APHA 2320. Internal Reference AN135

AN135

TOC and DOC in Water: A homogenised micro portion of sample is injected into a heated reaction chamber

packed with an oxidative catalyst that converts organic carbon to carbon dioxide. The CO2 is measured using a

non-dispersive infrared detector. The process is fully automated in a commercially available analyser. If required

a sugar value can be calculated from the TOC result . Reference APHA 5310 B.

AN190

Chemical oxygen demand can be calculated/estimated based on the O2/C relation as 2.67*NPOC ( TOC). This is

an estimate only and the factor will vary with sample matrix so results should be interpreted with caution.

AN190

Chloride by Aquakem DA: Chloride reacts with mercuric thiocyanate forming a mercuric chloride complex. In the

presence of ferric iron, highly coloured ferric thiocyanate is formed which is proportional to the chloride

concentration. Reference APHA 4500Cl-

AN274

Mercury by Cold Vapour AAS in Waters: Mercury ions are reduced by stannous chloride reagent in acidic solution

to elemental mercury. This mercury vapour is purged by nitrogen into a cold cell in an atomic absorption

spectrometer or mercury analyser. Quantification is made by comparing absorbances to those of the calibration

standards. Reference APHA 3112/3500.

AN311/AN312

Metals by ICP-OES: Samples are preserved with 10% nitric acid for a wide range of metals and some non-metals.

This solution is measured by Inductively Coupled Plasma. Solutions are aspirated into an argon plasma at

8000-10000K and emit characteristic energy or light as a result of electron transitions through unique energy

levels. The emitted light is focused onto a diffraction grating where it is separated into components .

AN320/AN321

Photomultipliers or CCDs are used to measure the light intensity at specific wavelengths. This intensity is directly

proportional to concentration. Corrections are required to compensate for spectral overlap between elements.

Reference APHA 3120 B.

AN320/AN321

ICP-OES (Ultrasonic Nebuliser): After preservation with 10% nitric acid, a wide range of metals and some

non-metals in solution can be measured by ICP- Ultrasonic nebulisation. Solutions are aspirated using an

ultrasonic nebuliser into an argon plasma at 8000-10000K and emit characteristic energy or light as a result of

electron transitions through unique energy levels. The emitted light is focused onto a diffraction grating where it is

separated into components.

AN320/AN322

Photomultipliers or CCDs are used to measure the light intensity at specific wavelengths. This intensity is directly

proportional to concentration. Corrections are required to compensate for spectral overlap between elements.

Reference APHA 3120 B

AN322

Free and Total Carbon Dioxide may be calculated using alkalinity forms only when the samples TDS is <500mg/L.

If TDS is >500mg/L free or total carbon dioxide cannot be reported . APHA4500CO2 D.

Calculation


CE121026 R0

Samples analysed as received.

Solid samples expressed on a dry weight basis.

Where "Total" analyte groups are reported (for example, Total PAHs, Total OC Pesticides) the total will be calculated as the sum of the individual

analytes, with those analytes that are reported as <LOR being assumed to be zero. The summed (Total) limit of reporting is calcuated by summing

the individual analyte LORs and dividing by two. For example, where 16 individual analytes are being summed and each has an LOR of 0.1 mg/kg,

the "Totals" LOR will be 1.6 / 2 (0.8 mg/kg). Where only 2 analytes are being summed, the " Total" LOR will be the sum of those two LORs.

Some totals may not appear to add up because the total is rounded after adding up the raw values.

If reported, measurement uncertainty follow the ± sign after the analytical result and is expressed as the expanded uncertainty calculated using a

coverage factor of 2, providing a level of confidence of approximately 95%, unless stated otherwise in the comments section of this report.

Results reported for samples tested under test methods with codes starting with ARS -SOP, radionuclide or gross radioactivity concentrations are

expressed in becquerel (Bq) per unit of mass or volume or per wipe as stated on the report. Becquerel is the SI unit for activity and equals one

nuclear transformation per second.

Note that in terms of units of radioactivity:

a. 1 Bq is equivalent to 27 pCi

b. 37 MBq is equivalent to 1 mCi

For results reported for samples tested under test methods with codes starting with ARS -SOP, less than (<) values indicate the detection limit for

each radionuclide or parameter for the measurement system used. The respective detection limits have been calculated in accordance with ISO

11929.
