Executive Summary
Core Consultants Pty Ltd (Core) carried out an acid sulfate soil (ASS) investigation for a proposed residential
development with a single level basement carpark at 47 Witta Circle Noosa Heads.
The results from this investigation indicate that the fill materials across the site have a low likelihood of
containing existing, actual or potential acidity. However, based on the testing carried out to date soils with
actionable levels of potential acidity appear to be limited to the natural soils below 2 m. The calculated liming
rate required for full neutralisation of this potential acidity in the natural material is 31 kg CaCO3/m³
Based on the results of the investigation and the proposed earthwork, the risk of impact to the surrounding
environment is considered low to moderate. Provided that the management measures outlined in Section 7.0
of this report are adhered to and an ASS MP is prepared for the project and implemented, the environmental
risk will be reduced further.

1.0 INTRODUCTION
This report details the results of an acid sulfate soil (ASS) investigation carried out by Core Consultants Pty
Ltd (Core) for a proposed residential development at 47 Witta Circle, Noosa Heads (the Site). The
investigation was undertaken at the request of SCG Consulting Engineers (SCG).
The ASS investigation was undertaken in order to assess the extent and severity of ASS materials across
the site which may be at risk of disturbance by the proposed residential development (primarily excavation of
the basement carpark). This report details the results of the above investigation and includes
recommendations regarding the extent and management of ASS.
The investigation was undertaken in accordance with the State Planning Policy – State Interest Guideline
‘Water Quality’ (August 2014).
2.0 PROPOSED DEVELOPMENT
Information provided by SCG indicates that the proposed development will comprise a single storey
residential dwelling over a single level basement carpark. Excavations for the single level basement carpark
are expected to extent to depths of approximately 2.5 m below existing ground level (bgl).
3.0 SITE DESCRIPTION
The site is approximately 616 m2 in area and is bound by Witta Circle followed by residential houses to the
north, residential dwellings to the east and west and Weyba Creek to the south. Weyba Creek flows directly
into the Noosa River and the Coral Sea, and is subjected to the associated tidal fluctuations.
It is understood that the site was filled with dredge spoil during excavations of Weyba Creek in the 1970’s.
However no information about possible ASS treatment or verification of the dredge spoil could be found. At
the time of the investigation the site was vacant (refer Plate 1 below).
Plate 1: General Site Conditions looking south
4.0 ACID SULFATE SOIL OVERVIEW
The development of ASS is commonly the result of marine or estuarine deposition of sulfate and iron bearing
sediments in the presence of an abundant source of readily decomposable organic matter resulting in the
deposition of pyrite. This pyrite is stable within the soil so long as anoxic conditions prevail. Oxidation of this
1
Page 5
J000154-001-R-Rev0 November 2015
material produces acidic conditions and oxidation typically occurs as the material is exposed above the water
table by excavation, and by lowering the water table during dewatering processes.
Previous experience and available guidelines indicate that ASS are normally restricted in extent to recent
(Holocene to Pleistocene age) soil horizons deposited in a saline environment below RL 5 m. The State
Planning Policy 2014 (SPP14) "State Interest Guideline – Water Quality” (August 2014) (SPP14) applies to
land, soil and sediment at or below 5 m AHD where the natural ground level is less than 20 m AHD. Within
such areas the SPP14 applies to development involving any of the following:
Excavating or otherwise removing 100 m³ or more of soil or sediment; or
Filling of land involving 500 m³ or more of material with an average depth of 0.5 m or greater.
The topography of the site is consistent with the above criteria (i.e. surface elevation below RL 5 m AHD)
and the proposed development involves excavations that would exceed the above trigger levels. Therefore
the SPP14 is applicable to this site due to the proposed excavations and an assessment of potential
disturbance of ASS is required.
The aims of this investigation were to:
Conduct an ASS investigation in general accordance with the requirements of the State Planning Policy
2014 "State Interest Guideline – Water Quality” (August 2014) with sampling and analysis planned using
the Queensland Department of Natural Resources and Mines (NRM) "Guidelines for Sampling and
Analysis of Lowland Acid Sulfate Soils in Queensland - 1998", developed by the Queensland Acid
Sulfate Soils Investigation Team (QASSIT).
Identify the presence or absence of ASS across the proposed development area;
If necessary, assess the likely impact of the proposed development on ASS and groundwater;
If necessary, provide prudent management measures so that the release of acid leachate from
disturbed soil and groundwater does not have significant adverse effects on the natural and built
environment or human health; and
Advise whether a stand-alone ASS Management Plan is required for the proposed works.
The investigation method, findings and recommendations are discussed in Sections 5, 6 and 7, respectively.
5.0 METHODOLOGY
5.1 Published Information
A desktop review of published geological and ASS maps was undertaken. Information reviewed as part of
the assessment included the following:
1:100,000 Series Gympie Special Geological Map, Sheet 9445 & Part 954, First Edition 1999
1:100,000 Acid Sulfate Soils, Redcliffe to Teewah, Map 2 (DNR-SEA-I-AO-3235),
Department of Natural Resources & Mines, First Edition 1999
The findings from the desktop assessment are presented in Section 6.1.
5.2 Fieldwork
The ASS investigation was planned with reference to State Government policies 1, the Queensland Sampling
Guidelines2 and the findings of the desktop assessment. For disturbances below RL 5 m, the Guidelines
recommend 4 locations for sites up to one hectare. The Guidelines also require ASS sampling to at least 1
m below the depth of disturbance.

In general accordance with the above and based on our experience in the area, 3 boreholes (designated
BH1 to BH3) were drilled using a 4WD mounted drill rig (with vibro-core and push tube sampling capabilities)
to depths of up to 3.5 m bgl across the site. Due to the size of the site (616 m 3) and our experience in the
area it was determined that 3 boreholes would be sufficient to assess the presence or absence of ASS
across the site.
The fieldwork was carried out by an experienced environmental scientist from Core on 5 November 2015.
Borehole locations are shown on Figure 1, and reports of boreholes are attached in Appendix A along with
explanatory notes.
To enable groundwater monitoring, and allow for groundwater sampling, BH1 was completed as a
groundwater monitoring well (designated GW1).
Soil samples were recovered from all boreholes at approximately 0.25 m intervals to the depth of
investigation. ASS sampling protocols outlined in the “Guidelines for Sampling and Analysis of Lowland Acid
Sulfate Soils (ASS) in Queensland 1988” (Ahern et al., 1998) were observed in the field in order to minimise
oxidation of the samples prior to laboratory testing.
5.2.1 Groundwater Monitoring
Groundwater quality monitoring was undertaken at GW1 in order to provide a ‘snap shot’ of the water quality
of the site for future reference (e.g. ‘baseline’ data) and to enable an appraisal of the influence of ASS (if
any) on water quality.
The groundwater level in GW1 was measured by an experienced environmental scientist on 5 November
2015. A groundwater sample was recovered and screened in the field, after initial purging. Water samples
were tested in field for temperature, pH, salinity and electrical conductivity (EC) using an Aquaread
‘Aquaprobe’ AP 2000-D model water quality analyser.
The sample was then dispatched to Eurofins/MGT (Eurofins) to undergo further analysis. Eurofins is a
National Association of Testing Authorities (NATA) accredited for the analytical tests. Results of groundwater
monitoring are summarised in Section 6.4. Eurofins laboratory results are attached in Appendix B.
Groundwater sampling, field testing, sample handling and dispatch procedures were performed in
accordance with Core procedures, the Department of Environment and Heritage Protection (EHP) Monitoring
and Sampling Manual 2009 Version 2 September 2010 and the Murray Darling Basin Groundwater Quality
Sampling Guidelines (MBDC 1997).
5.3 Laboratory Testing
A total of 42 samples were screened at our laboratory to assess field pH (pHF) and pH after oxidation (pHFOX)
using 30 % hydrogen solution.
The pHF/pHFOX screening method consists of two steps. In the first step, the field pH of a 1:5 soil/water
suspension is measured (pHF). In the second step, a 30% Hydrogen Peroxide solution is added to a second
sample of the same material which is then heated to accelerate the oxidation of the sample. The pH after
oxidation (pHFOX) is then measured. A significant difference between the pH F and pHFOX results is an
indication of potential acid sulfate soils (PASS); however, test results may be affected by other inclusions
such as shell material and organics.
Based upon the results of pH screening tests, 12 samples (approximately one sample per metre per
borehole) were selected and dispatched to Eurofins to undergo quantitative analysis by the Chromium
Reducible Sulfur (SCR) suite in accordance with ASS Method 23F and 22B laboratory procedures of Ahern et
al (2004).
This SCR method includes analysis of ‘inherent buffering capacity’ from naturally occurring alkaline materials
(i.e. calcite, coral debris, fine shell fragments) and 'retained acidity' which includes sulfur held in stable
oxidation minerals such as 'jarosite' and allows for calculation of 'net acidity'. The SCR test method was
selected in preference to the Suspension Peroxide Oxidation Combined Acidity & Sulfur (SPOCAS) method
3

J000154-001-R-Rev0 November 2015
as is gives more accurate indications of pyrite content where significant amounts of organic matter (and
organic derived acidity) are present in the soil samples.
An overall acid-base accounting method was used to calculate a ‘net acidity’ value which is used to qualify
analytical test results and calculate liming rates. This equation is:
Net Acidity = Actual Acidity (as TAA) + Retained Acidity (as SNAS) + Potential Acidity (as SCR) - insitu Acid
Neutralising Capacity (ANC).
The Eurofins laboratory certificates of analysis, chain of custody documents and laboratory quality control
documents are attached in Appendix B and the results are summarised in Table B1. Observations and
discussion on the laboratory findings are given in Sections 6.5 and 6.6.
6.0 RESULTS OF THE INVESTIGATION
6.1 Published Data
Available geological information3 indicates that the site is underlain by Quaternary age “Anthropogenic
deposits: landfill, mine tailings and rubble”.
An extract of the regional geology map is shown below in Plate 2.

6.2 Subsurface Conditions
The boreholes encountered a sequence of inferred alluvial soils comprising:
Firm Sand (FILL) yellow and pale yellow to depths of approximately 1.5 m to 2.0 m bgl, over
Sand (Natural) grey and pale grey, with some silt and organics to depths of 3.5 m bgl (maximum depth
of investigation).
6.3 Groundwater
Groundwater was initially encountered in all boreholes during the investigation at depths of between 1.5 m
and 2.0 m bgl. The groundwater level was recorded at 2.3 m bgl during groundwater monitoring on 5
November 2015. It should be noted that drilling operations were undertaken during a “dropping tide” with
groundwater monitoring of GW1 undertaken at / around low tide. It is anticipated that the extent of
groundwater seepage encountered during earthworks and construction will be dependent upon the prevailing
weather conditions at that time and tidal conditions. However, the groundwater level is expected to rise
closer to the ground surface.
6.4 Groundwater Quality Analysis
A groundwater sample was collected from GW1 on 5 November 2015 to provide a ‘snapshot’ of the
groundwater conditions. The results of groundwater analysis are summarised in Table 1.

The groundwater pH (6.2) indicates that the groundwater is slightly acidic. The electrical conductivity (EC)
value (437 us/cm) and salinity (0.15 ppt) indicate that the groundwater is fresh, however this may be a result
of the sample being collected on a low tide and may not represent the groundwater conditions during a full
tidal cycle.
The Chloride:Sulfate (Cl-:SO42-) ratio provides an indication of whether the environment is influenced by ASS.
A Cl-:SO42- ratio of sea water is approximately 7, a Cl-:SO42- ratio below this value can indicate that excess
sulfur may be present as sulfides. However, in this case the sulfate concentration recorded was considered
too low to provide reliable information from which any conclusions could be drawn.
The groundwater was generally recorded being net alkaline with results of alkalinity testing indicating
moderate to high alkalinity levels, and with a pH value of pH 6.2 the buffering capacity of the groundwater
would be considered adequate to maintain acceptable pH levels in the future under current conditions.
Total iron (Fe) concentration in the groundwater is indicative of an iron rich environment, common along
coastal Southeast Queensland. The dissolved Fe concentration also indicates possible past influence by
lower pH groundwater.
Total and dissolved aluminium (Al) concentrations recorded were consistent with other sites located along
the coastline of Southeast Queensland.
6.5 Preliminary Screening
Results of preliminary screening are summarised in Table B1 (Appendix B).
Soil pH (represented by pHF results) was found to range between pH 3.6 and pH 6.6 (slightly to highly
acidic), with the majority of the samples being between pH 5.5 and pH 6.5, indicating a low probability of the
presence of actual ASS at the borehole locations.
A mixture of low to high level reactions to addition of hydrogen peroxide was observed in all samples. There
was a noted difference in the pHF and pHFOX test results for the majority of samples tested below 2 m (natural
soils). The pHFOX in the samples collected from the natural soils ranged from pH 1.3 to pH 2.8 indicating a
high potential for the presence of PASS. However, the pHFOX ranged from pH 2.9 to pH 6.1 in the fill material
suggesting a low to moderate potential for the presence of PASS.

6.6 Quantitative Soils Analysis
Table 3 below shows the ASS action levels adopted in Queensland. These categories are used to identify
whether action / management of ASS spoil is required, based on ‘net acidity’. For major fill works and
disturbances of more than 1,000 tonnes, an action criterion of 0.03% S equivalents (18 moles / tonne) is
adopted for all soil types; and was adopted for this investigation.

Results of quantitative analysis carried out are summarised in Table B1, attached. Laboratory result
certificates are included in Appendix B.
Results of the 12 samples analysed are summarised below:
All 12 samples returned Titratable Actual Acidity (TAA) results below the Action Criteria of 18 mol H+/
tonne (0.03%S), ranging between 2 mol H+/ tonne to 7 mol H+/ tonne.
6 samples within the fill material returned Oxidisable Sulfur as SCR at levels below action criteria with
values ranging from <0.005 %S (Laboratory Level of Reporting (LOR)) up to 0.017 %S (11 mol
H+/tonne).
6 samples within the natural material (below 2 m BGL) returned Oxidisable Sulfur as SCR at levels above
the action criteria with values ranging from 0.086 %S (54 mol H+/tonne) up to 0.35 %S (220 mol
H+/tonne).
pHKCl values did not exceed pH 6.5 and as such, no samples were subjected to analysis for acid
neutralising capacity (ANC).
No samples returned pHKCl values of less than pH 4.5, and as such no further analysis for retained
acidity (SNAS) was carried out
The test results indicate that negligible levels of actual acidity were present in the samples analysed.
Results of SCR tests indicate that oxidisable sulfur is present at high levels within the natural soils (generally
below 2.0 m bgl) across the site. However, results indicate negligible to low levels present within the fill
materials across the site.
Of the 12 samples analysed, net acidity exceeded the appropriate QASSIT ‘Action Criteria’ (for bulk
earthworks) in all samples collected within the natural materials (below 2 m bgl).

J000154-001-R-Rev0 November 2015
6.7 Extent and Severity
The results from this investigation indicate that the fill materials across the site have a low likelihood of
containing existing, actual or potential acidity. However, based on the testing carried out to date soils with
actionable levels of potential acidity appear to be limited to the natural soils below 2 m.
The SPP14 Guidelines require that the level of treatment for management of ASS is based on treatment of
all existing and potential acidity. The results of the laboratory testing have been accumulated in an Acid-
Base Account to give the Net Acidity for each sample in units of mol H+/tonne as presented in Table B1.
This value has been calculated from sulfur trail potential acidity (SCr) plus actual acidity (TAA).
Liming rates have been calculated in kg CaCO3/t and kg CaCO3/m³ using a factor of safety (fineness factor)
of 1.5 and an assumed bulk density of 1.8 tonne/m3. Calculation of liming rates required for full
neutralisation of combined actual and potential acidity are presented in Table 4, below.

6.8 Risk Assessment
As excavations for the proposed basement will intersect soils with potential acidity, there will be a
requirement for management of that acidity.
Information provided to Core indicates that a majority of the basement excavation will be within the fill
material with approximately 0.5 m of excavation within the natural material. It is expected that approximately
200 m3 of excavated material will be natural and require treatment. The likely volume of disturbance
indicates that management of potential acidity at this site would be classified as Very High (VH) treatment
(5 to 25 tonnes of aglime) in accordance with Queensland Soil Management Guidelines V4.0 - Table 4.2
The SPP14 Guidelines require that for Category VH treatment a stand-alone Acid Sulfate Soil Management
Plan (ASS MP) must be provided. Recommendations on strategies to be included in the ASS MP are
outlined below in Section 7.0.
Based on the results of the investigation and the proposed earthwork, the risk of impact to the surrounding
environment is considered low to moderate. Provided that the management measures outlined in Section 7.0
of this report are adhered to and an ASS MP is prepared for the project and implemented, the environmental
risk will be reduced further.
7.0 RECOMMENDATIONS
The results of this investigation indicate there is the likelihood of disturbance of soils with high levels of
potential acidity associated with the basement excavations. It is recommended that an ASS MP be
developed and implemented. Recommendations on strategies to be included (as a minimum) in any such
ASS MP should include:
Excavated soil must be managed by neutralisation of potential acidity. Good quality agricultural lime
should be thoroughly mixed with the spoil. Any lime treatment should be carried out in accordance with
Queensland Acid Sulfate Soil Technical Manual, Soil Management Guidelines (Ver. 4.0. 2014).
Lime neutralisation treatment rates and methodologies should take into account the acid tolerant nature
of some species in the immediate receiving environment.
8
Page 12
J000154-001-R-Rev0 November 2015
Treatment should be carried out on prepared pads. However, due to site constraints it may be more
practical to mix the lime insitu in 300 mm layers prior to excavation. This would require verification
testing of the material before removal off site.
Verification sampling and analysis is to be carried out on the treated soil to confirm that appropriate
amounts of the neutralising agent have been incorporated into the soil at a rate of 1 sample per 50 m2 of
natural material removed.
Groundwater quality should be monitored through new groundwater monitoring wells located across the
site.
Management of groundwater seepage and rainfall collected in excavations and other works areas on
site, including treatment recommendations, must be incorporated into the ASS MP.
During construction, it is recommended that all waters collected from groundwater or surface water
inflow, be retained, monitored and if needed, treated to comply with the appropriate discharge criteria
prior to discharge offsite.

Sample History
Where 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 (regarding both quality and NATA accreditation).
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.

Internal Quality Control Review and Glossary
General
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.
Holding Times
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.

QC - Acceptance Criteria
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 20-130%.
QC Data General Comments
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, Toxophene & Chlordane are not added to the LCS.
4. Organochlorine Pesticide analysis - where reporting Spike data, Toxophene 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 Arochlor 1260 in Matrix Spikes and LCS's.
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 RPD's are calculated from raw analytical data thus it is possible to have two sets of data.

Sample History
Where 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 (regarding both quality and NATA accreditation).
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.

Internal Quality Control Review and Glossary
General
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.
Holding Times
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

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.

QC - Acceptance Criteria
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 20-130%.
QC Data General Comments
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, Toxophene & Chlordane are not added to the LCS.
4. Organochlorine Pesticide analysis - where reporting Spike data, Toxophene 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 Arochlor 1260 in Matrix Spikes and LCS's.
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 RPD's are calculated from raw analytical data thus it is possible to have two sets of data.

Qualifier Codes/Comments
Code Description
Liming rate is calculated and reported on a dry weight basis assuming use of fine agricultural lime (CaCO3) and using a safety factor of 1.5 to allow for non-homogeneous mixing
S01 and poor reactivity of lime. For conversion of Liming Rate from 'kg/t dry weight' to 'kg/m3 in-situ soil' multiply 'reported results' x 'wet bulk density of soil in t/m3'
S02 Retained Acidity is Reported when the pHKCl is less than pH 4.5
S03 Acid Neutralising Capacity is only required if the pHKCl if greater than or equal to pH 6.5
S04 Acid Sulfate Soil Samples have a 24 hour holding time unless frozen or dried within that period
