ES Executi ve Summar y
Quasar Resources Pty Ltd (Quasar) commissioned URS Australia Pty Ltd (URS) on 9 July 2008 to undertake a
soil survey at the proposed Four Mile Mining Lease Area (Four Mile MLA) located adjacent to the Heathgate
Resources Pty Ltd Beverley Uranium Mine Lease Area (Beverley) on the arid plains between the Northern
Flinders Ranges and Lake Frome. Four Mile is approximately 600 km north of Adelaide and 300 km north-east
of Port Augusta, South Australia. Quasar proposes that the initial mining of the Four Mile MLA would be by In-
Situ Recovery (ISR) methods, utilizing the existing Beverley infrastructure and workforce for processing the
uranium.
This report is one of a several baseline studies that will contribute to the environmental approval process that
include a Public Environment Report (PER) required under the Australian Government Environment Protection
and Biodiversity Conservation Act 1999 (Four Mile Uranium Mine EPBC 2008/4252), a Lease Proposal and
Mining and Rehabilitation Program (MARP) required under the South Australian Mining Act 1971.
The objectives of this soil survey were to summarise the available descriptive information on soils with reference
to the landforms, provide indicative baseline chemical and physical data of soil across various landforms, and to
provide recommendations for management of the soils across the general landforms to minimise degradation of
soil structure and erosion. This soil survey did not map the distribution of the main soil types across the study
area but was designed to describe the physical and chemical nature of soils likely to be present across the
proposed mining Four Mile lease area.
The scope of works included review available published material and aerial photographs to determine the major
landform and soil types in the vicinity of the site, excavation of test pits across the site and testing of soil
samples for analysis for soil physical and chemical characterisation, reporting on observed soils and discussion
of soil analytical results with reference to the soil properties.
The investigation test pit locations were designed to assess variation in soil parent materials and soil physical
properties in the vicinity of likely development areas within the proposed MLA (e.g. trunklines, wellfields, roads)
and across landform types (low and high elevation gibber plains, minor and major floodplains).
Soils on the Four Mile MLA area can be classified as brown sandy clay profiles on the more elevated and better
drained areas and brown sandy clay underlain by clayey gravel profiles on the floodplain zone of the lower
plains. The topography of the majority of the site is relatively flat or gently sloping and as such the risk of
significant rill erosion and runoff is likely to be low where the natural soil surface is protected from channelled
overland flow. Gibbers are present at the surface of much of the plains of the site; the resulting surface has a
low permeability but is generally considered quite resistant to water erosion.
The surface soils are saline (low to moderately low salinity) and non-sodic while subsoils are saline (high
salinity) and sodic. Variations in this pattern were associated with enhanced leaching along major creek lines.
Soils across the site have low wet strength, slaking when wet. This limits their traffickability when wet.
The baseline data also established background soil chemical conditions (primarily pH, electrical conductivity and
major ion chemistry) in the event of an unexpected chemical release such as saline extraction solutions from the
trunkline.
Management strategies are presented to minimise soil degradation and erosion from activities such as
excavation, handling and stockpiling of materials including topsoils during development of roads, tracks,
structures such as wellhouses, and mud pits for drilling. It is noted that it is not the disturbance of soil per se that
has the potential to cause environmental impacts at the site; rather it is the potential for soil disturbance to lead
to problems such as enhanced erosion and sedimentation or difficulties with later rehabilitation and
revegetation.

1.1 Context
Quasar Resources Pty Ltd (Quasar) commissioned URS Australia Pty Ltd (URS) on 9 July 2008 to undertake a
soil survey at the proposed Four Mile Mining Lease Area (Four Mile MLA) located adjacent to the Heathgate
Resources Pty Ltd (Heathgate) Beverley Uranium Mine Lease Area (Beverley) on the arid plains between the
Northern Flinders Ranges and Lake Frome. Four Mile is approximately 600 km north of Adelaide and 300 km
north-east of Port Augusta, South Australia (Figure 1). The survey area encompassed the Four Mile lease area
(Figure 2).
This report is one of a several baseline studies that will contribute to the environmental approval process that
include a Public Environment Report (PER) required under the Australian Government Environment Protection
and Biodiversity Conservation Act 1999 (Four Mile Uranium Mine EPBC 2008/4252), a Lease Proposal and
Mining and Rehabilitation Program (MARP) required under the South Australian Mining Act 1971. The
Department of the Environment, Water, Heritage and the Arts (DEH) and the Minerals Group within Primary
Industries and Resources SA (PIRSA) prepared guidelines on 17 September 2008 for the Lease Proposal and
MARP. Guideline criteria that are addressed (in full or partially) in this report are listed below.
4.13 Topsoil and subsoil
Describe and map the profile (type and depth) and the characteristics (e.g. cracking clays, light red soils,
red/brown earth – including productivity) of all soils on the proposed mine site. Identify any soil aspects that may
be an issue for disturbance or rehabilitation (e.g. acid sulphate, saline, non-wettable, etc)
4.16 Pre-existing site contamination and previous disturbance
Details should be given of any known contamination of the site and of any disturbance by previous mining
operations or other activities. Provide baseline soil physico-chemical properties of the site.
A detailed plan and cross-sections may be required to support this section.
5.5.4 Silt control and drainage
The following information must be provided on silt control and drainage:
• Location and design of silt management structures (e.g. silt retention dams)
• Runoff control on disturbed and rehabilitated areas
• Storage, diversion and disposal of clean water (discharge must comply with the applicable EPA water
policy)
Note that certified engineering and geo-technical design may be required for silt retention structures (if
considered necessary)
A plan showing the surface water movement for the whole mine site must be included to support this section.
The soil investigations conducted historically have been limited to description of the lithology and radionuclide
analysis of surface soils within creek lines. It is understood that no laboratory testing has been previously
carried out to assess the chemical and physical properties of surface and shallow subsurface soils across the
site.

1.2 Objectives
The objectives of this soil survey were to:
• summarise the available descriptive information on soils with reference to the landforms
• provide indicative baseline chemical and physical data of soil across various landforms
• provide recommendations for management of the soils across the general landforms to minimise
degradation of soil structure and erosion.
We note that this soil survey did not map the distribution of the main soil types across the study area but was
designed to describe the physical and chemical nature of soils likely to be present across the proposed Four
Mile MLA.
1.3 Scope of Works
Quasar requested the following scope of works for the soil survey:
• review available published material and aerial photographs to determine the major landform and soil
types in the vicinity of the site
• excavation of 10 test pits to an approximate depth of 1.5 m, logging of soils according to Australian
Standards (AS1726-1993) and collection of samples for analysis for soil physical and chemical
characterisation
• prepare a factual report summarising the existing soils and terrain information, describing soils
encountered in the test pits, and presenting and discussing soil analytical results with reference to the
soil properties
• present recommendations for management of the soils across the general landforms in the proposed
Four Mile MLA to minimise risk of soil structure degradation and erosion.
1.4 Summary of Proposed Mining Operations
Quasar proposes that the initial mining of the Four Mile MLA would be by In-Situ Recovery (ISR) methods,
utilizing the existing Beverley infrastructure and workforce for processing the uranium. Quasar has appointed
Heathgate as the mining operator for the project.
Mining will involve a pattern of injection and recovery wells drilled into the ore zone (‘the wellfield’). Groundwater
conditioned by an oxidant (hydrogen peroxide) and dilute sulphuric acid will be injected into the orebody to
dissolve the uranium; the recovery wells then pump the extraction solution containing dissolved uranium to the
surface for processing.
A satellite plant would be constructed at Four Mile, in which the uranium would be removed from the ISR liquor
by physical means, producing uranium-bearing resin, which would be trucked to the Beverley processing plant.
The resin would then be stripped of uranium and trucked back to the satellite plant.
1.5 Overview of Potential Soil Impacts from Mine Operations
Mining operations include the following activities that could have potential soil impacts such as erosion and
sedimentation and soil structural degradation:

• pedestrian foot traffic
• vehicle and machinery traffic (including off existing tracks)
• construction of roads
• excavation of mud pits for drilling
• construction and commissioning of wellfields including drilling, pipelines, wellhouses and bunds.
• clearance or degradation of vegetation.
A comparable study (Woodburn Associates 1996) assessed documented the traffic induced impacts from
development activity at the Beverley Uranium Mine (similar activities to those proposed at Four Mile). The
terrain features and soil disturbance and erosion issues are summarised in Table 1-1.

Table 1-1 indicates that low intensity traffic will have little effect on gibber-patterned surfaces, drainage gullies
and depressions, and the gently sloping plains. However low intensity traffic could cause surface disturbance
leading to erosion on the dissection slopes.
More intense traffic, involving heavy vehicles or regular light vehicle movements during development, could
break down the stability of the soil surface over wellfield areas. This impact can be minimised elsewhere if
vehicle traffic movements are restricted to designated roadways.

2.2 Climate, Topography, Geology and Soils
2.2.1 Climate
Four Mile MLA is located in an arid region of South Australia, adjacent to the Northern Flinders Ranges and in
their rain shadow. The area is characterised by low but highly variable, average rainfall. Meteorological data is
collected continuously at the Beverley weather tower.
Wooltana station homestead and Arkaroola are the closest Bureau of Meteorology rainfall recording stations to
the Beverley site (Figure 3-1). Mean annual rainfall at Wooltana at the foot of the Ranges is 192 mm (median
164 mm) and at Arkaroola within the Ranges the mean and median rainfall are 251 mm and 212 mm
respectively. There is a one-year-in-ten expectation of an annual total less than 80 mm.
Rainfall data is collected at the Beverley meteorological station using a tipping bucket and recorded every hour.
Six full years of rainfall data are available (2002 – 2007). The average of these six years is 109 mm; however,
the length of record is not sufficient to consider this the average rainfall of the site. Based on its location in the
rain shadow of the Ranges the average rainfall of the mining lease can be estimated at approximately 150 –
200 mm/yr.
Evaporation is measured at Beverley using a standard above-ground Class A evaporation pan located adjacent
to the weather tower, with a precision level meter linked to the weather station that logs every 24 hours. The
six-year average (2002-2007) is 3,433 mm/yr but this has occurred during below-average rainfall. The

estimated long-term average pan evaporation for the Beverley site, based on regional trends, is likely to be
between 3,000 and 3,500 mm.
Annual evaporation and rainfall data to date are shown in Figure 2-1.
Figure 2-1 Annual Pan Evaporation and Rainfall, Beverley
For November to March, mean maximum temperatures exceed 30°C and daily temperatures may exceed 40°C. Summer mean minima are around 20°C. Mean maximum temperatures are lowest for June and July, around 15°C. Mean minimum temperatures are <10°C, with <0°C daily minima recorded. Frosts are frequent, although actual white frosts appear less frequently because of the dryness of the air.
Mean and maximum temperatures on a quarterly basis to date are shown in Figure 2-2.

2.2.2 Topography and Physiography
A series of ephemeral water courses, rising in the Flinders Ranges, flow in a generally easterly direction across
the site. The largest of the watercourses in the vicinity is Four Mile Creek, which has a catchment area of
approximately 100 km2 (URS, 2007).
Figure 2-3 Topography and drainage
The Four Mile MLA is on the western boundary of a broad, almost featureless plain approximately 45 km wide
lying between the eastern margin of the Northern Flinders Ranges and Lake Frome. Maximum relief on the site
is approximately 110 m. Woodburn Associates (1996) describe the physiography of the site in more detail.
2.2.3 Terrain Patterns and Units
Historical terrain mapping and assessment covering most of the Four Mile lease area and the adjacent the
Beverley mining lease was carried out by Woodburn and Associates (1996). From this study, the following
terrain units (local area based on physiographic features) and patterns (regional area based on landscape
types) were recognised:
• the patterned Gilgai and gibber areas
• the major streams (alluvium)
• the broadly re-entrant drainage lines and gullies of the dissection slopes

• the flat to very gently sloping or undulating plains with some gilgai units
• discontinuous flat to very gently easterly sloping High Plain generally above 110 m elevation
• gently to steeply sloping dissection slopes of the High Plain generally between 80 and 110 m elevation
• gently sloping, broadly rounded foot slopes and interfluves of the second-order streams forming the lower
margin of the High Plain generally between 70 and 90 m elevation.
2.2.4 Surficial Geology
The oldest sediments influencing the land surface characteristics are the relatively thick deposits of the
Willawortina formation. These comprise extremely to very poorly sorted brown, bouldery to pebbly, silty or
sandy clays with some carbonate nodules. Close to the Ranges the sediments are coarser with cobbles and
large boulders. This unit underlies the High Plains, west of the Poontana Fault, and crops out towards the base
of some of the dissection slopes, particularly those associated with Paralana and Four Mile Creeks (Heathgate
Resources, 1998). The presence of extremely poor sorting, numerous channels with medium scale cross
bedding and laminated calcareous silts with red-mottling and carbonate concretions typical of flood plain
deposits indicate deposition in an alluvial fan environment for the Willawortina formation.
The late Pleistocene, Eurinalla formation overlies the Willawortina formation both conformably and
unconformably. The Eurinalla formation comprises clayey fine to medium grained, poorly sorted orange brown
sands, impregnated with gypsum at the base. The sands are interbedded with grey-green brown sandy and
silty clays (Woodburn Associates, 1996). The Eurinalla formation is indicated as the parent material of the soils
of the more elevated areas. On the Low Plains, east of the Poontana Fault, there are extensive fluvial sediments
forming very low angle fan and sheet deposits overlying the Eurinalla formation.
At the land surface, the sediments of the Coonarbine formation consist of a thin veneer of reddish brown sands
and silty and clayey sands (Heathgate Resources ,1998).
2.2.5 Soil Types
Broadscale mapping across the study area in the Atlas of Australian Soils identified the soils as Sodosols.
These soils are typically deep, have a strong texture contrast between the surface and subsoil horizons and
have accumulation of exchangeable sodium in the subsoil that makes them highly dispersive and erodible by
water. Consequently, once the surface is disturbed the erosion risk is high.

Figure 2-4 Atlas of Australian Soils mapping
The Flinders Soil Conservation Board (1997) mapping delineated the land systems across the district and
identified that the survey area is located within the Mumpie Plains (Mm) land system comprising undulating
gibber tablelands with gilgais. Gilgai is a ‘micro-relief’ associated with cracking clay soils that consists of
depressions and/or hummocks of varying size, shape and frequency. Shrink-swell properties with changes in
moisture content in the subsoils cause heaving that leads to the microrelief.
Soil survey of the nearby Gammon Ranges National Park, south-east of the site (Department of Environment
and Heritage 2006) described two main soil groups, namely reddish loams and deep duplex soils. All soils are
alkaline, which is a reflection of the arid environment. The reddish loams are more common than the deep
duplex soils that are limited in their extent to the stony plains, pediments, tablelands and broad undissected
areas of alluvial fans. Apart from the Gilgai soils the soils are massive and hardsetting. These features limit
infiltration from rainfall and exacerbate runoff and erosion risks.
Previous descriptions of soils (topsoil and subsoils) on the site have noted that soil surface material varies
across the site from boulders and cobbles in a sandy matrix, through gravels and sands to silts and clays (URS,
2007). The quartz, quartzite and granite gibbers found on many of the flatter surfaces occur mainly on scald
areas with little vegetation.
Soils of the plains were in almost all cases soils silty or sandy clays of medium to high plasticity, grading rapidly
to clays (Woodburn Associates, 1996). Soil associations in the study area were described from drilling and
logging of thirty shallow pushtube boreholes as follows:
• soils of the Low Plains are generally reddish brown, very silty and sandy clays grading to gravel at depth of
1.5 m or greater
• soil profiles of the High Plains and upper elevations of the Low Plains comprise duplex, crusty red-brown
sandy and silty clays with gibber/ gilgai patterning overlying heavier blocky brown clays

• soils in the slight depressions comprise brown very silty clays, gilgai soils exhibiting a cracked (0.3 and
about 0.7 m depth), loose or “puffy” brown soil surface in drier periods, with only occasional gibber.
• soils on the dissected slopes have the surface horizon in many cases been removed by erosion, resulting in
a gibber surface with uniform clay profile for 1 to 1.5 m, with gravel at depth
• alluvial soils on creeklines consisting of recently and reworked deposits of major stream channels and the
finer alluvium of levees and adjacent flats, comprising deep clean sands with the major channels and
gravels and sands in the banks and bars.
Woodburn Associates (1996) noted that loss of the surface soil horizon has occurred at the heads of small
gullies towards the upper sections of the dissection slopes and in the lower sections of the drainage channels,
exposing the underlying high plastic clays. These clays, along with others from the site were not dispersive
(Class 4 dispersion rating, indicating slaking of aggregates in water upon wetting but generally no dispersion
occurs).

3.1 Sampling Plan
The investigation test pit locations were designed to assess variation in soil parent materials and soil physical
properties in the vicinity of likely development areas within the proposed mining lease (e.g. trunklines, wellfields,
roads). Also, the landform variation (low and high elevation gibber plains, minor and major floodplains) was
sampled. The sampling plan is outlined in Table 3-1.

3.2 Survey and Sampling Methodology
Soil samples were collected according to relevant Australian Standards (Standards Australia 2005, AS4482-
2005).
Heathgate’s Aboriginal Liaison Officer reviewed and approved permits to access to locations before movement
of the field vehicle and backhoe off existing tracks and intrusive works were commenced, to ensure that no
areas of Aboriginal cultural heritage significance were disturbed,.
Ten investigation test pits (TP01 to TP10) were excavated to approximately 2.0 m depth below ground level
using a backhoe with a 600 mm wide toothed bucket. Test pits were benched to allow safe access for the URS
environmental scientist to carry out logging and collection of samples.
Soils were logged according to the method outlined in AS1726-1993; the logs are presented in Appendix C. All
test pits were backfilled with excavated soil prior to abandonment.
Soil samples were generally collected using clean nitrile gloves and a hand trowel from discrete layers. Soil
samples were placed in laboratory supplied, clean glass jars which were sealed with teflon lined lids or clean
plastic ‘snap-lock’ bags, labelled and placed within eskies prior to and during delivery to URS Adelaide (and
then the laboratory) under chain of custody protocols.
The location of each test pit was marked using a Global Positioning System (GPS). Test pit locations are
attached in Figure 2.

General parameters (all samples):
• pH
• Electrical conductivity (salinity)
Cation exchange properties (15 samples from 5 representative locations, namely test pits TP01, TP04, TP05,
TP08, TP09 covering various general landform):
• exchangeable cations (Ca2+, Mg
2+, Al
3+, Na

Research House Laboratory, a NATA accredited laboratory, conducted the dispersion tests.
3.3.1 Quality Assurance
In addition to the analysis of blind field duplicate samples (minimum 10% of primary samples), selected field
triplicate samples (minimum 10% of primary samples) were also submitted to Labmark Environmental, a NATA
accredited laboratory, for analysis of the above analytes.
It is noted that the laboratories’ NATA accreditation did not cover analysis of Emerson Class Number and
Exchangeable Cations (Labmark only).

4.1 Field Results
The sub surface conditions encountered in the test pits indicate a generalised sub surface profile as outlined in
the table below.
Table 4-1 Generalised Sub Surface Conditions
Depth Description
0 - 0.1 Silty Sandy CLAY; low to medium plasticity, brown to orange brown, fine sand, minor quartz gravels, occasional minor gibber gravel and cobbles at surface
0.1 – 1.0 Silty Sandy CLAY; medium to high plasticity, brown, fine sand, inferred calcareous, blocky
1.0 – 2.0 Silty Clayey GRAVEL; fine to coarse, brown with occasional white staining, calcareous silt, with some mixed cobbles, gravels and cobbles comprising mix of one or more of schist, quartzite, gneiss, pegmatite and granite.
Differences in soil morphology were associated with variation in physiography as follows:
• major ephemeral creekline (Four Mile Creek) dissecting the landscape - layers of sands and gravels were
encountered to depth (test pit TP05)
• floodplain areas or surface gibber in the vicinity of minor or major creeklines - a subsurface layer of gravel
was encountered in the majority of test pits (with the exception of test pit TP02)
• higher elevation surface consisting of gibber plains distant from ephemeral drainage or creeklines -
encountered only clay throughout the profile (three test pits TP01, TP06 and TP10).
No fill materials, unusual staining or odours were observed within the test pits.
Light colours in some subsoils indicated the presence of carbonates.
Mixed rock types at depth with gravels and cobbles indicated of alluvial parent material (transport by water) or
colluvial soil (transport by gravity) rather than residual soils formed from rock in-situ.
The soil morphologies were similar to that observed by Woodburn Associates (1996).
4.2 Analytical Results
The analytical results were however compared against published criteria for the evaluation and classification of
soils according to chemical and physical properties such as acidity/ alkalinity, salinity, sodicity, slaking and
dispersion. Soil analytical results, with laboratory certificates and chain of custody documentation presented
within Appendix A. Analytical results are summarised in Table 1 (attached).
4.2.1 pH
In general, soil pH values indicated slightly alkaline to alkaline conditions within surface and subsurface soils
and occasional variation with depth. Soil pH varied from 7.1 in subsurface soil from test pit TP05 to 9.6 in
subsurface soil from test pit TP04.

4.2.2 Electrical Conductivity
Electrical conductivity (EC) reflects the leaching environment, which is associated with water redistribution and
infiltration in the landscape. EC was observed to increase with soil depth. For example, surface soil EC in test
pit TP08 was 27 µs/cm and subsurface EC was 5,860 µs/cm.
Reported EC in surface soils (i.e. top 100 to 200 mm) were less than the guideline for saline soils (1,000 µs/cm)
with the exception of sample TP06_0-0.1 (3,310 µs/cm).
Subsurface soil EC varied between 3,000 to 5,000 µs/cm with a some exceptions such as TP05_0.75-0.95
(such as 107 µs/cm), which was located within a major ephemeral creekline that created an enhanced leaching
environment. .
4.2.3 Exchangeable Cations
Exchangeable cations reflect soil mineralogy, leaching environment and fertility status. The reported
concentrations of exchangeable cations indicate that the cation exchange surfaces of the clay fraction in these
soils are dominated by Ca2+. The order of dominance (highest to lowest concentrations) within samples is
generally Ca2+ then Mg
2+ or Na
+ and finally K
+.
4.2.4 Cation Exchange Capacity
The cation exchange capacity (CEC) is defined as the measure of the total capacity of a soil to hold
exchangeable cations, given in units of charge/ unit mass of soil (cmol(+)/kg = meq/100g). It therefore indicates
the negative charge present per unit mass of soil. Reported concentrations of CEC varied from 6 meq/100g soil
in surface sample TP09_0-0.2 to 169 meq/100 g soil in subsurface sample TP05_1.0-1.2, the highest reported
CEC values corresponding with high reported sample EC concentrations. Higher CEC values were generally
reported in samples of clay material compared to gravel material, but with some exceptions. The sum of the
exchangeable cations Ca2+, Mg
2+, Na
+, K
+ and Al
3+ is reported equivalent to the CEC.
4.2.5 Sodium Adsorption Ratio (SAR)
The SAR is expressed as the ratio of exchangeable cations (Na+) / (Ca
2+ + Mg
2+). Reported SAR values ranged
from 0.88 in samples TP01_0.2-0.4 and TP09_0-0.2 to 15.1 in TP08_0.15-0.35, with the majority of samples
reporting values less than 5, indicating non-sodic or low sodic conditions. Reported values varied widely
between primary and interlaboratory duplicate sample results but are considered repeatable when compared to
blind field duplicate sample results. Analysed surface soil samples generally reported SAR values indicative of
non-sodic conditions. Near surface samples of clay soils, TP08_0.15-0.25 and TP09_0.25-0.45 reported SAR
value of 15.1 and 14, respectively, indicating highly sodic conditions. A discussion of the results with reference
to sodicity is presented in Section 5.1.
4.2.6 Major Anions
The highest reported sulphate concentrations corresponded with high reported sample EC concentrations.
Reported concentrations of sulphate (as SO42-) varied markedly from 20 mg/kg in samples TP04_0-0.05 and
TP04_0.65-0.85 to 12,900 mg/kg in sample TP01_1.4-1.6, with the majority of sample concentrations below
100 mg/kg.
Most of the surface soil samples analysed reported concentrations of chloride below or slightly above the
laboratory limits of reporting (LOR), indicative of chloride (a conservative ion) being leached to depth. Reported
concentrations of chloride also varied markedly from below the LOR of 10 mg/kg in a number of samples up to

3,040 mg/kg in sample TP08_0.15-0.35. All soil samples from test pit TP04 reported concentrations of chloride
below the LOR, but also reported low EC concentrations.
Emerson Class
The Emerson test (AS1289 cl.3.8.1) gives a semi-quantitative assessment of the stability of the soil when wet
and is used to indicate erodibility by water. Emerson Class Number varied from 3.1 to 6, indicating a tendency
of all soil to slake upon wetting with no or partial dispersion, as discussed in Section 5.2.1 Emerson Class
interpretations are outlined in Figure 4-1.

4.3 Analytical Data Validation
Validation summary reports and tables of field duplicates, laboratory duplicates are provided as Appendix B.
Data validation guidelines were based upon guidance documents published by the United States Environmental
Protection Agency (US EPA, 1999 and 2002). The process involves the checking of analytical procedure
compliance and an assessment of the accuracy and precision of analytical data from a range of quality control
measurements, generated from both the field sampling and analytical programs.
Specific elements that have been checked and assessed for this project include the following:
• preservation and storage of samples upon collection and during transport to the laboratory
• sample holding times
• use of appropriate analytical and field sampling procedures
• required limits of reporting
• frequency of conducting quality control measurements
• laboratory blank results
• field duplicate results
• laboratory duplicate results
• matrix spike/matrix spike duplicate (MS/MSD) results
• surrogate spike results
• apparently unusual or anomalous results, e.g. laboratory results that are inconsistent with field observations
or measurements.
Based on the analytical data validation procedure employed, the overall quality of the analytical data produced
was considered to be of an acceptable standard for interpretive use. However, the following were noted:
• The recommended holding time for the extraction of pH, conductivity, soluble major ions and chloride and
the analysis of moisture content in soil is 1 week. This is not considered to affect the interpretation of the
results, however results may potentially be biased compared with field measurements of pH and
conductivity.
• Field duplicate relative percent differences (RPDs) were elevated for a number of exchangeable ions in
TP08_0.15-0.35 and its corresponding intra-laboratory (QC11_20/09/08) and inter-laboratory
(QC12_20/09/08) field duplicates. RPDs were also elevated for sulphate, sodium adsorption ratio and cation
exchange capacity in the inter-laboratory (QC12_20/09/08) field duplicate. The lack of precision for all
analytes listed above is related to high natural soil variability in relation to sample size taken and should be
taken into consideration when evaluating results.
• Field duplicate RPDs were elevated for chloride, exchangeable potassium and exchangeable sodium in
TP01_0-0.2 and its corresponding intra-laboratory field duplicate QC03_20/09/08. Field duplicate RPDs
were also elevated for exchangeable and electrical conductivity in inter-laboratory field duplicate
QC04_20/09/08. This apparent lack of precision for all analytes listed above is related to high natural soil
variability in relation to sample size taken and should be taken into consideration when evaluating results.

5 Discussion
5.1 Salinity and Sodicity
Salinity
Electrical conductivity (EC) is a measure of soil salinity. A soil is defined as being saline when the level of
salinity of soil water (concentration of ions) affects plant growth. However, plants have different susceptibilities
to soil salinity. Soil salinity classes for Australian conditions have developed on the basis of restriction of growth
to crop plants, not on the basis of restriction of growth to native pastures or endemic plant species. Table 5-1
presents a soil salinity classification accepted in South Australia.
Table 5-1 Soil Salinity Classes*
EC1:5 (dS/m)
Class of Soil Salinity ECse
(dS/m) Sand Sandy Loam Clay Loam Clay
Low <2 0.17 0.20 0.29 0.40
Moderately Low 2-4 0.33 0.40 0.57 0.80
Moderate 4-8 0.50 0.60 0.86 1.20
Moderately High >8 0.67 0.80 1.14 1.60
* As sourced from Kelly and Rengasamy (2006)
Referring to Table 5-1, the surface soils were classified as low to moderately low salinity while subsoils were
classified as highly saline. The leaching environment influences the degree of salt accumulation in a soil.
Leaching environment is related to water distribution in the landscape, soil permeability, the presence of
vegetation (evapotranspiration) and the amount and seasonal distribution of rainfall (Shaw, 1999). Arid
conditions associated with low rainfall and high evaporation have lead to the accumulation of salts over time in
subsoils in the study area. This is a feature that reduces the ability of soils to support vegetation once the
surface soil is removed.
Sodicity
Sodicity is expressed as the amount of sodium relative to exchangeable calcium and magnesium in the soil. A
soil is sodic when there is sufficient sodium to interfere with its structural stability, often affecting plant growth
(Kelly & Rengasamy, 2006). When sufficient exchangeable sodium is present to influence soil behaviour, soil is
said to be sodic.
Leaching of cations other than sodium (e.g. calcium and magnesium) from the soil profile of saline soils and
accumulation of sodium on the cation exchange surface lead to the formation of sodic soils (Kelly &
Rengasamy, 2006). Australian soils are defined as sodic if the SAR is greater than 5 (see table below).
However, sodicity is better defined by the dispersion and swelling behaviour of soils (Rengasamy & Churchman,
1999).

* Given that ESP ≈ 2SAR1:5 (for 1:5 soil:water extracts) as sourced from Kelly and Rengasamy (2006)
Because sodicity causes or enhances the swelling and dispersion of soil clay particles, it leads to the
deterioration of the physical condition of soils (Rengasamy and Churchman, 1999) and predisposes them to
hardsetting when dry and being erodible when wet. Sodic soils tend to suffer from poor soil structure including
hard soils, hardpans, surface crushing and rain pooling on the surface, which limit water infiltration, drainage,
plant growth, cultivation and access with machinery and enhance runoff (Kelly and Rengasamy, 2006).
Problems associated with surface sodicity can affect soils through the following mechanisms (Kelly &
Rengasamy, 2006):
• high soil strength (very hard soils) and surface crusting can reduce root penetration and seedling
emergence
• blocking of pores can reduce water infiltration into soil, increasing waterlogging and potential for run-off
Table 5-3 outlines the effects from salinity and sodicity on plant growth and soil structure.

* sourced from Cass (1999)
Cations other than sodium, particularly calcium and to some extent magnesium (divalent cations), confer
stability to soil aggregates by preventing dispersion. Also high soluble salt concentration, although detrimental to
plant growth, flocculates wet soils and has a favourable effect on structural stability (Rengasamy and
Churchman, 1999).

Soils at the site can be classified generally as very-saline and non-sodic, with some exceptions of near surface
and subsurface soils that can be classified as very saline and sodic. A soil can be sodic without being saline, or
both sodic and saline (Kelly & Rengasamy, 2006).
5.2 Soil Structural Stability
Soil structural stability refers to the resistance of soil to the structural rearrangement of pores and particles when
exposed to different stresses such as cultivation, trafficking, tramping, irrigation and rainfall (Cass, 1999).
Deterioration to soil structure occurs from two hydro-mechanical processes: slaking of aggregates and
dispersion of clays. Many, but not necessarily all, soils slake. Some soils slake and disperse. Most sub-soils
slake and some disperse. Slaking and dispersion in sub-soils are associated with hard, massive visible
structure. A few soils disperse but do not slake (Cass, 1999).
Soil structure is also degraded by gross mechanical stresses such as raindrop impact, compaction, tillage and
tramping.
5.2.1 Slaking and Dispersion
The results of Emerson Class tests results for the soil samples indicated that aggregates of all surface soils and
subsoils are prone to slaking upon wetting. Subsoils were generally not dispersive after remoulding. The
presence of carbonates accounts for this behaviour (Emerson Class 4), indicating stability when wet and
disturbed. Surface soil samples generally displayed complete or partial dispersion after remoulding the soil at
field capacity water content (Emerson Class 5 and 6), indicating moderate structural stability if the soil is
disturbed. Consequently, limiting disturbance will reduce the risk of dispersion, and hence erosion by water, in
the soil surface.

6 Conclu sion s, Recommendatio ns and Limitation s
6.1 Conclusions
Soils on the proposed Four Mile MLA can be classified as brown sandy clay profiles on the more elevated and
better drained areas and brown sandy clay underlain by clayey gravel profiles on the floodplain zone of the
lower plains. The topography of the majority of the site is relatively flat or gently sloping and as such the risk of
significant rill erosion and runoff is likely to be low where the natural soil surface is protected from channelled
overland flow. Gibbers are present at the surface of much of the plains of the site; the resulting surface has a
low permeability but is generally considered quite resistant to water erosion.
The surface soils are saline (low to moderately low salinity) and non-sodic while subsoils are saline (high
salinity) and sodic. Variations in this pattern were associated with enhanced leaching along major creek lines.
Soils across the site have low wet strength, slaking when wet. This limits their traffickability when wet.
The baseline data also established background soil chemical conditions (primarily pH, electrical conductivity and
major ion chemistry) in the event of an unexpected chemical release such as saline extraction solutions from the
trunkline.
6.2 Recommendations
Management strategies will be needed to minimise the risk of soil degradation and erosion from activities such
as excavation, handling and stockpiling of materials including topsoils during development of roads, tracks,
structures such as wellhouses, and mud pits for drilling.
Recommendations to prevent spillage of chemicals to ground are not covered as part of this report. It is noted
that it is not the disturbance of soil per se that has the potential to cause environmental impacts at the site;
rather it is the potential for soil disturbance to lead to problems such as enhanced erosion and sedimentation or
difficulties with later rehabilitation and revegetation.
Management of Soil Erosion
A sediment and erosion control plan will need to be implemented to minimise the risk to the receiving
environment. Management in such a plan will aim to minimise erosion risk from wind, raindrop impacts and
surface water runoff by:
• maintaining the protective surface lag of gravels and cobbles across gibber plains
• minimising the height of stockpiled soils
• providing a buffer between soil stockpiles and flow lines or creeks
• treating water runoff from roads through sediment traps to minimise runoff velocity and sediment discharge
to streams
• placement of tracks along contours (rather than down slopes) with adequate cross drainage
• using rollers instead of grader blades to construct vehicle access where permanent roads are not required,
• removing windrows and contour rip all roads and tracks to rehabilitate them if they are no longer in use
• importing suitable road base materials to form road pavements that will minimise dust generation problems
associated with in-situ soils.

• maintaining perennial plant cover to minimise water and wind erosion leading to land degradation
• implementing a dust suppression program using water trucks
• minimising the area of land disturbance through a clearing and access permit system and restricting access
to designated tracks and roads
• protecting cut slopes from erosion using stone (gibber) or environmental matting.
Topsoil Management
It is recommended to segregate and selectively place topsoil and subsoil when carrying out intrusive works (e.g.
excavation of pits for mud drilling) for two reasons:
1) to bury material which is adverse to plant growth or which may contaminate surface soils or vegetation
2) to salvage materials that will assist in the rehabilitation program, in particular topsoils that are relatively
non-saline and non-sodic.
Management of Soil Structure
Soil structure degradation is most likely when the soils are wet. To avoid this occurring it is recommended to:
• limit the area and frequency of disturbance by traffic particularly during wet conditions
• maintain or increase vegetative cover and surface gravels and cobbles
• use soil conditioners such as gypsum and/or lime (where such materials are not naturally present) to
amend dispersive soil properties and/or sodicity.

If fill has been imported on to the site at any time, or if any buildings constructed prior to 1970 have been demolished on the site or materials from such buildings disposed of on the site, the site may contain asbestos or ACM. Without limiting the generality of sub-clauses (h) and (j), even if asbestos was tested for and those test results did not reveal the presence of asbestos at specific points of sampling, asbestos may still be present at the site if fill has been imported at any time, or if any buildings constructed prior to 1970 have been demolished on the site or materials from such buildings disposed of on the site.
j) Subsurface conditions can vary across a particular site and cannot be exhaustively defined by the investigations described in this Report. It is unlikely therefore that the results and estimations expressed in this Report will represent conditions at any location removed from the specific points of sampling.
k) Except as specifically stated above, URS makes no warranty, statement or representation of any kind concerning the suitability of the site for any purpose or the permissibility of any use, development or re-development of the site.
l) Use, development or re-development of the site for any purpose may require planning and other approvals and, in some cases, environmental regulatory authority and accredited site auditor approvals. URS offers no opinion as to whether the current use has any or all approvals required, is operating in accordance with any approvals, the likelihood of obtaining any approvals for development or redevelopment of the site, or the conditions and obligations which such approvals may impose, which may include the requirement for additional environmental works.

Labmark Internal Quality Control Review
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. Matrix spike recoveries are calculated on an 'As Received' basis; the parent sample result is moisture
corrected after the % recovery is determined.
3. Proficiency trial results are available on request.
4. Actual PQLs are matrix dependant. Quoted PQLs may be raised where sample extracts are diluted due to interferences.
5. Results are uncorrected for matrix spike or surrogate recoveries.
6. Test samples duplicated or spiked, are for this job only and are identified in the following QC report.
7. SVOC analyses on waters are performed on homogenized, unfiltered sample, unless noted otherwise.
8. When individual results are qualified in the body of a report, refer to the qualifier descriptions that follow.
9. Samples were analysed on an as received basis.
10. This report replaces any interim results previously issued.
Holding Times
Please refer to 'Sampling and Preservation Chart for Soils & Waters' for holding times. (LM-FOR-ADM-020)
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 Acknowledgement.
If the Laboratory did not receive the information in the required timeframe, and regardless of any other integrity issues,
suitablity 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 an RPD

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 preformed, 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 insuffient 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 date(s) and/or time(s) are shown bracketed, these have been assumed by the laboratory for processing purposes. If the sampling time is displayed as 0:00 the information was not provided by client.
CAS Number = Chemistry Abstract Services number
LOR = Limit of reporting
^ = This result is computed from individual analyte detections at or above the level of reporting

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%.

Analysis Holding Time Compliance
The following report summarises extraction / preparation and analysis times and compares with recommended holding times. Dates reported represent first date of extraction or analysis and precludes subsequent
dilutions and reruns. Information is also provided re the sample container (preservative) from which the analysis aliquot was taken. Elapsed period to analysis represents number of days from sampling where no
extraction / digestion is involved or period from extraction / digestion where this is present. For composite samples, sampling date is assumed to be that of the oldest sample contributing to the composite. Sample date
for laboratory produced leachates is assumed as the completion date of the leaching process. Outliers for holding time are based on USEPA SW 846, APHA, AS and NEPM (1999). A listing of breaches is provided in
the Summary of Outliers.
Holding times for leachate methods (excluding elutriates) vary according to the analytes being determined on the resulting solution. For non -volatile analytes, the holding time compliance assessment compares the
leach date with the shortest analyte holding time for the equivalent soil method. These soil holding times are: Organics (14 days); Mercury (28 days) & other metals (180 days). A recorded breach therefore does not
guarantee a breach for all non-volatile parameters.
