1. INTRODUCTION
Geo-Logix Pty Ltd (Geo-Logix) was engaged by Donald Cant Watts Corke (DCWC) on behalf of Australian
Catholic University (ACU) to conduct a groundwater impact assessment for the proposed underground car
park at the ACU Strathfield Campus located at 205A Barker Road, Strathfield NSW 2135 (Figure 1). The
purpose of the assessment was to obtain site-specific groundwater data to evaluate groundwater impacts
in the short-term (construction dewatering) and in the long-term (drained basement design).
1.1 Proposed Development
Based on concept plans provided by DCWC (Attachment A), ACU plans to build a one level underground
car park beneath the present day sports field in the northwest portion of the university campus. Geo-Logix
understands that the proposed development has the following parameters:
• Current/finished ground level at 33.35 metres Australian Height Datum (mAHD);
• Basement level at 29.8 mAHD;
• General excavation base at approximately 29.6 mAHD; and
• Footing excavation base at approximately 28.8 mAHD.
2. SITE INFORMATION
2.1 Site Identification and Description
The investigation area comprises the following properties:
Street Address Lot and
Deposited Plan (DP) Approximate Area (m2)
25A Barker Road, Strathfield NSW 2135 Part of Lot 11 DP869042 11,000
Property information sourced from NSW Land and Property Information.
The following site descriptions are based on observations made during the site investigation conducted by
Geo-Logix on 13 and 18 April 2017.
The site was located in the Sydney suburb of Strathfield, NSW and comprises the northwest portion of the
ACU Strathfield Campus encompassing an area of approximately 11,000 m2 (Figure 2).
The site was primarily occupied by an existing sports field, slightly domed in the centre with asphalt carpark
and ACU buildings to the south, residential properties to the west, Edgar Street and ACU buildings to the
north and additional sports fields to the east.
2.2 Regional Geology
The 1:100,000 Sydney Geology Map (Geological Survey of New South Wales, 1983) describes geology
underlying the site as Triassic age Bringelly Shale, characterised by shale, carbonaceous claystone,
laminite, fine to medium grained lithic sandstone and rare coal.

2.3 Regional Hydrogeology
Reference to the NSW Office of Water online All Groundwater Map (allwaterdata.water.nsw.gov.au/
water.stm) indicates there are no registered groundwater bores within a 500 m radius of the site. A copy of
the groundwater bore search map is provided as Attachment B. Groundwater is expected to follow regional
topography and flow towards an unnamed tributary of Powells Creek to the north.
3. SAMPLING ANALYSIS PLAN
3.1 Scope of Work
In order to assess the potential groundwater impacts, Geo-Logix completed the following scope of work:
• Installation of one groundwater monitoring well to 4.5 metres below grade (mbg), the
maximum expected depth of excavation, installed with 3 m of slotted screen, screened
across the encountered soil rock interface at 2.5 mbg;
• Installation of a second groundwater monitoring well to a depth of 6.5 mbg, targeted to
the depth of groundwater as encountered during drilling. The well was installed with 4.5 m
of slotted screen, such that the slotted screen intersects encountered groundwater within
the rock and was sealed below the soil–rock interface encountered at 0.5 mbg;
• During drilling, encounter soils, rock and groundwater inflow were logged by Geo-Logix’s
field geologist, Aidan McKenzie;
• Following drilling and installation, the groundwater monitoring wells were allowed to
equilibrate for approximately 100 hours. After equilibration, Geo-Logix returned to site to
gauge standing groundwater level in the wells, perform a slug test to assess aquifer
parameters including hydraulic conductivity, measure groundwater parameters including
pH, electrical conductivity, redox potential, dissolved oxygen and temperature, and collect
groundwater samples for laboratory analysis; and
• Groundwater samples were collected using low-flow techniques in accordance with
industry best practices. The resultant groundwater samples were submitted to a NATA
accredited laboratory for analysis of physical parameters and analytes of the “Suggested
general groundwater quality analytical suite” for dewatering assessment in accordance
with the Sydney Coastal Councils Groundwater Management Handbook:
Suite Parameters/Analytes
Physical parameters Alkalinity, electrical conductivity (EC), pH, redox potential (Eh), total
dissolved solids (TDS) and total hardness
Major anions Sulphate (SO4=), chloride (Cl-), bicarbonate (HCO3=)

*Based on the understood geology and site use the following organic compounds are excluded from Geo-
Logix’s assessment: semi-volatile chlorinated hydrocarbons, volatile chlorinated hydrocarbons, chlorinated
aliphatics, pesticides, phenols and polychlorinated biphenyls
The Geo-Logix field investigation was conducted on 13 and 18 April 2017.
3.2 Groundwater Well Installation Methodology
Soil borings MW1 and MW2 were completed using truck mounted Geoprobe drill rig utilising solid stem
augers. Borings were initiated using with a “V” shaped hardened steel bit (V-bit) to refusal on rock and
completed using a wing-shaped Tungsten Carbide bit (TC-bit). Boring MW1 was drilled to a target depth of
4.5 mbg and boring MW2 was drilled to a target depth of 6.5 mbg. During drilling the encountered soils
were logged in accordance with the Unified Soil Classification System (USCS). The depth of encountered
groundwater was logged in each well during drilling.
Groundwater wells were installed in accordance with Minimum Construction Requirements for Water Bores
in Australia, Edition 3 (NUDLC, 2012). Geo-Logix converted soil bores MW1 and MW2 into groundwater
monitoring wells. The groundwater wells were constructed of Class 18, 50 mm diameter PVC pipe. Slotted
PVC casing 3-4.5 m in length was installed from depths between 1.2 to 4.2 mbg in well MW1 and 2.0 to
6.5 mbg in well MW2. A sand filter pack extended from the base of the borings to 0.5 m above the top of
the slotted PVC casing and was sealed with 0.5 m of hydrated bentonite pellets above the sand pack. A
cement grout was used to seal the borehole annulus to surface. The wells were finished to grade with a
plastic valve box. Construction details are presented in the attached boring logs (Attachment C).
Following well installation, no groundwater was present in well MW1. Groundwater elevation was measured
in well MW2 and the well was developed by surge and purge with a disposable plastic bailer until dry,
approximately 20 L of water was removed.
3.3 Aquifer Hydraulic Conductivity Testing
Hydraulic conductivity of the saturated zone was determined by performing a rising head test, also known
as a slug test, on well MW2. The rising head test was completed by measuring the initial groundwater head
elevation, removing 7.5 L of water from the well and recording the recharging head elevation at 30 second
intervals over a period of 25 minutes. The recovery data from the slug tests was solved utilising aquifer
software Aqtesolv® to obtain a value for hydraulic conductivity (K). A copy of the output from Aqtesolv® is
provided in Attachment D.
Groundwater Impact Assessment 1701029Rpt01FinalV01_15May17 ● Page 4
3.4 Groundwater Sampling Methodology
Groundwater wells were sampled approximately 100 hours after installation. Groundwater samples were
collected by dedicating ¼” LDPE tubing into each well. The LDPE tubing was connected to disposable
silicon tubing that runs through a peristaltic pump. The peristaltic pump was set to very low flow rates to
reduce sample turbidity. During well purging, water parameters, pH, dissolved oxygen, turbidity,
conductivity and temperature were measured. Groundwater Well MW1 did not contain sufficient water to
collect samples for laboratory testing. Groundwater samples were collected from well MW2 when water
quality parameters and head elevation stabilised. Groundwater sample logs are presented in Attachment
E.
Groundwater samples were collected in 40 mL hydrochloric acid preserved vials, 200 mL glass amber
bottles, 200 mL nitric acid preserved plastic bottles, 500 mL unpreserved plastic bottles, 250 mL hydrogen
sulfate preserved plastic bottles, 500 mL sodium thiosulfate preserved plastic bottles and 200 mL
hydrochloric acid preserved plastic bottles. All groundwater samples were filtered in the field for dissolved
metals analysis. Samples were labelled, placed on ice in an esky and transported under chain of custody
to a NATA Accredited Laboratory for analysis.
3.5 Assessment Criteria
To aid in considering groundwater disposal options, Geo-Logix has assessed groundwater analytical data
against the following criteria:
National Health and Medical Research Council (NHMRC, 2008) Guidelines for Managing Risks in
Recreational Water
The NHMRC has established recreational water assessment criteria as 10 time the Australian Drinking
Water Guidelines for the protection of human health from direct contact and immersion in water. These
guidelines have been adopted as Tier 1 risk based assessment criteria to assess the risk to the public from
onsite reuse of groundwater for irrigation or disposal to stormwater.
Department of Environment and Climate Change (DECC, 2007) Improving the Environmental
Management of New South Wales Golf Courses, Section 2.2 Water quality criteria
The DECC manual for the environmental management of golf courses provides water quality criteria for
assessing the impact of irrigation water salinity and ion content on the health of turf. These guidelines have
been adopted as Tier 1 risk based assessment criteria to assess the salinity risks of reusing groundwater
for onsite irrigation.
Australian and New Zealand Environment and Conservation Council (ANZECC, 2000) Australian
and New Zealand Guidelines for Fresh and Marine Water Quality
Based on the site location and nearest surface water, Geo-Logix has adopted the ANZECC slightly
disturbed freshwater and NSW lowland river trigger values as Tier 1 risk based assessment criteria for the
protection of aquatic environments in assessing the suitability of onsite groundwater for disposal to
stormwater.

4. INVESTIGATION RESULTS
4.1 Site Geology and Hydrogeology
Based on Geo-Logix’s soil borings and review of the previous geotechnical reports completed by Coffey
Geotechnics in 2011 and 2012, onsite geology comprises 0.5 to 2.5 m of fill and residual clay overlying
fractured shale and sandstone bedrock. Groundwater was encountered at approximately 4 mbg during
drilling. During groundwater sampling, groundwater was measured in well MW1, which only slightly
penetrated the water table, at approximately 4 mbg and was measured in MW2, which penetrated further
into the water table, at approximately 3 mbg. Geo-Logix considers that groundwater exists as a confined
aquifer within the fractured bedrock. A profile of the onsite geology, including interpreted excavation and
groundwater elevations, is presented in Figure 3.
Based on the results of Geo-Logix’s rising head test performed in well MW2, hydraulic conductivity (K) of
the fractured sandstone in this location is 0.03407 m/day or approximately 4×10-7 m/s. The hydraulic
conductivity of the shale bedrock, encountered elsewhere onsite, is expected to exhibit a lower hydraulic
conductivity. Locally increased hydraulic conductivity may be encountered in association with fractures in
the bedrock exposed during excavation.
4.2 Laboratory Analytical Results
Groundwater analytical results are summarised in Tables 1 through 7. A Stiff diagram and Piper plot are
provided as graphical representations of the groundwater ion chemistry in Attachment F. Laboratory reports
are presented in Attachment G.
Physical Parameters
The pH of groundwater is neutral with a pH of 7.2. Based on groundwater conductivity of 13,000 µS/cm
and Total Dissolved Solids (TDS) of 7,000 mg/L, onsite groundwater is classed as saline. The groundwater
also has a high hardness value – 1,400 mg/L (Table 1). The measured conductivity exceeds Geo-Logix’s
adopted assessment criteria for reuse of the groundwater for onsite irrigation and disposal to stormwater.
Anions and Cations
Sodium, chloride and the calculated Sodium Adsorption Ratio (SAR) exceed Geo-Logix’s adopted
assessment criteria for reuse of the groundwater for onsite irrigation (Table 2).
Ion balancing indicates a good quality groundwater sample was obtained and the majority of groundwater
ions are accounted for in the tested analytes.
Heavy Metals
Heavy metals, including aluminium (Al), antimony (Sb), arsenic (As), barium (Ba), boron (B), cadmium (Cd),
chromium (Cr), copper (Cu), iron (Fe), lead (Pb), lithium (Li), manganese (Mn), mercury (Hg), nickel (Ni),
selenium (Se), silver (Ag) and zinc (Zn) were not detected at concentrations greater than expected
background levels in the groundwater sample collected from well MW2 (Table 3).
Nutrients
Ammonia was detected at a concentration of 1 mg/L in groundwater from well MW2. Other nutrients,
including nitrogen and phosphorous forms, were not detected at concentrations greater than laboratory
reporting limits in the groundwater sample collected from well MW2 (Table 4).
Groundwater Impact Assessment 1701029Rpt01FinalV01_15May17 ● Page 6
Microbiological Organisms
Microbiological Organisms, including escherichia coli, faecal streptococci and total coliforms, were not
detected at concentrations greater than laboratory reporting limits in the groundwater sample collected
from well MW2 (Table 5).
Petroleum Hydrocarbons
Low concentrations of long chain Total Recoverable Hydrocarbons (TRH), including 200 µg/L TRH >C16-
C34 and 600 µg/L >C34-C40, were removed by silica gel clean up. Petroleum Hydrocarbons were not
detected at concentrations greater than laboratory reporting limits in the groundwater sample collected
from well MW2 (Table 6).
Polyaromatic Hydrocarbons
Polyaromatic Hydrocarbons were not detected at concentrations greater than laboratory reporting limits in
the groundwater sample collected from well MW2 (Table 7).
5. DISCUSSION
5.1 Excavation and Construction Dewatering
Groundwater was not encountered above the top of rock (30.5 to 32.5 mAHD) either during drilling (28.9
mAHD) or at the stabilised piezometric head elevation (30.0 mAHD). The presence of groundwater is not
expected to significantly affect excavation methods. Geo-Logix expects that excavation may be carried out
by a combination of excavator and ripping of the underlying bedrock.
Following excavation, groundwater inflow may affect construction of the proposed footings and carpark
pavements. As the proposed excavations do not penetrate deeply into the aquifer, the speed and degree
of groundwater inflows are expected to depend greatly on rock fractures encountered during excavation.
Geo-Logix has calculated dewatering volumes using two analytical models:
• Linear trench flow to the excavation perimeter [Q/m trench = K•(H2 – h2)/R0]; and
• A number of wellpoints (n) placed across the excavated area [Q= n•π•K•(H – h)/ln(R0/rw)].
These calculations were performed using variations of the following parameters:
• The measured hydraulic conductivity (K) of 4×10-7 m/s;
• An aquifer head (H) of approximately 10 m;
• An assumed drop of 1.0 to 1.5 m in groundwater elevation (H – h);
• An assumed wellpoint radius (rw) of 0.0625 m; and
• An assumed radius of influence (R0) of 30 m.
Based on these preliminary dewatering calculations and past experience, Geo-Logix expects that total
groundwater inflow would not exceed 10-50 kL/day. Dewatering is expected to be achievable using sump
pumps and French drains placed as conditions may require.
Groundwater Impact Assessment 1701029Rpt01FinalV01_15May17 ● Page 7
5.2 Groundwater Disposal Options
Onsite Irrigation
Based on the analytical results of groundwater sampled from MW2, reuse of groundwater for onsite
irrigation would be suitable from a human health perspective. However, elevated groundwater salinity might
result in ion toxicity to irrigated turf, resulting in scalding. Onsite desalination would likely be necessary
prior to reuse for irrigation. Geo-Logix would recommend consultation with a turf specialist prior to using
onsite groundwater for irrigation.
Disposal to Stormwater Infrastructure
Council approval would be required prior to the disposal of groundwater to stormwater infrastructure.
Removal of Total Suspended Solids (TSS) and Total Dissolved Solids (TDS) by flocculation and
desalination would likely be required prior to disposal in this manner. Other than salinity, as indicated by
the groundwater conductivity and TDS, water quality is considered suitable for discharge to stormwater.
Disposal to Wastewater Infrastructure
Contaminated groundwater may be disposed to wastewater infrastructure under a trade waste agreement
with Sydney Water. As the onsite groundwater generally contains very low levels of contaminants, Geo-
Logix considers that a trade waste agreement is unlikely to be granted.
Offsite Disposal by Trucking
Onsite groundwater may be disposed offsite as waste by pump truck for disposal to a licensed water
treatment facility. Laboratory analytical results would need to be provided to the waste disposal company.
5.3 Long-term Dewatering
If a drained basement design is adopted, in contrast with a tanked design, and depending on the presence
of vertical rock fractures encountered during excavation and fluctuations in groundwater elevation, long-
term dewatering of the carpark might be required. Volumes may be expected to be lower than those
experienced during construction. As groundwater exists in fractured shale/sandstone and the general
basement elevation is not significantly below the encountered groundwater head elevation (potentiometric
surface), only approximately 0.4 m, long-term dewatering would not be expected to cause significant soil
piping or subsidence under surrounding properties. Geo-Logix would recommend that those areas which
are proposed to be lower than approximately 29.5 mbg, such as elevator shafts, be tanked to prevent
groundwater seepage.
5.4 Recommendations for Further Investigation
Onsite groundwater elevation data is limited to a single measurement. During the course of a year
groundwater elevation may fluctuate in response to changing rainfall and evaporation rates (recharge).
Based on the site location, geology and topography, Geo-Logix’s experience indicates that fluctuations in
groundwater elevation may be expected to be less than 1 m and are likely less than 0.5 m. However,
fluctuations may be atypical due to presence of the sports fields which comprise a large infiltration recharge
area.
In order to gain a better understanding of seasonal groundwater fluctuations, Geo-Logix recommend that,
prior to construction, an in well groundwater elevation sensor be installed in groundwater well MW2 over
the longest duration practical to measure changes in the groundwater elevation over time.

Groundwater Impact Assessment 1701029Rpt01FinalV01_15May17 ● Page 9
Geo-Logix assumes no responsibility in respect of any changes in the condition of the Site which have
occurred since the time when Geo-Logix gathered data and/or took samples from the Site on its site
inspections dated 13 and 18 April 2017.
Given the nature of asbestos, and the difficulties involved in identifying asbestos fibres, despite the
exercise of all reasonable due care and diligence, thorough investigations may not always reveal its
presence in either buildings or fill. Even if asbestos has been tested for and those tests' results do not
reveal the presence of asbestos at those specific points of sampling, asbestos or asbestos containing
materials may still be present at the Site, particularly if fill has been imported at any time, buildings
constructed prior to 1980 have been demolished on the Site or materials from such buildings have been
disposed of on the Site.
Where the Scope of Works does not include offsite investigations, Geo-Logix provides no warranty as to
offsite conditions, including the extent if any to which substances in the Site may be emanating off site,
and if so whether any adjoining sites have been or may be impacted by contamination originating from
the Site.
Where the Scope of Works does not include the investigation, sampling, monitoring or other testing of
groundwater in, on or under the Site, Geo-Logix provides no warranty or representation as to the quality
of groundwater on the Site or the actual or potential migration of contamination in groundwater across or
off the Site.
Subsurface site conditions are typically heterogeneous, and may change with time. Samples taken from
different points on the Site may not enable inferences to be drawn about the condition of areas of the Site
significantly removed from the sample points, or about the condition of any part of the Site whatsoever, in
particular where the proposed inferences are to be drawn a long time after the date of the report.
Geo-Logix has prepared this report with the diligence, care and skill which a reasonable person would
expect from a reputable environmental consultancy and in accordance with environmental regulatory
authority and industry standards, guidelines and assessment criteria applicable as at the date of this
report. Industry standards and environmental criteria change frequently, and may change at any time
after the date of this report.

Sample HistoryWhere 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.
