South Australia’s unique and precious natural resources are fundamental to the economic and social wellbeing of the State. It is critical that these resources are managed in a sustainable manner to safeguard them both for current users and for future generations. The Department of Water, Land and Biodiversity Conservation (DWLBC) strives to ensure that our natural resources are managed so that they are available for all users, including the environment. In order for us to best manage these natural resources it is imperative that we have a sound knowledge of their condition and how they are likely to respond to management changes. DWLBC scientific and technical staff continues to improve this knowledge through undertaking investigations, technical reviews and resource modelling.

Report DWLBC 2004/57 ii Northern Adelaide Plains Groundwater Monitoring Network Upgrade 1. INTRODUCTION

Between September 2001 and February 2002 an upgrade of the Northern Adelaide Plains (NAP) monitoring network was undertaken. In total, eleven new wells were drilled in Angle Vale and Virginia areas. Two old government owned steel cased, non-pressure cemented monitoring wells (MPA 64 and MPA 75) were backfilled and replaced with new wells. All eleven monitoring wells were completed in the T2 Aquifer. The review of the Northern Adelaide Plains (NAP) groundwater monitoring network conducted in 1999, recommended upgrading of the network. New and replacement wells were recommended to be drilled into the T1 and T2 confined aquifers, as well as to backfill and rehabilitate some old monitoring wells. While the 2000/01 Drilling Program has prioritised and undertaken an upgrade of mainly the T1 Aquifer monitoring network in the Waterloo Corner area because of the lack of data and high consumption of groundwater from the T1 Aquifer in this area, the 2001/02 Drilling Program has undertaken upgrading of the T2 Aquifer monitoring network in the Angle Vale and Virginia areas. Eleven wells were drilled and two wells were backfilled between September 2001 and February 2002. All monitoring wells were drilled and completed in the T2 confined aquifer. Two government non-pressure cemented monitoring wells (MPA 64 and MPA 75) were backfilled and replaced by new wells under the same program.

Report DWLBC 2004/57 1 Northern Adelaide Plains Groundwater Monitoring Network Upgrade 2. RESULTS OF DRILLING

The objective of the drilling of eleven monitoring wells (MPA 153 to MPA 159; PTA 115 and PTA 116; PTG 83 and PTG 84) and backfilling of two government non-pressure cemented monitoring wells MPA 64 and MPA 75 (Fig. 1) was to upgrade the monitoring of the T2 aquifer in the Angle Vale and Virginia areas. A summary of encountered lithology and well completion details are provided in Tables 1–4, with comprehensive description of lithology encountered over the well profiles included in Appendix A of this report. A suite of geophysical logs was conducted over each hole prior to casing: gamma, neutron, point resistivity, caliper, spontaneous potential, density, medium inductivity and deep inductivity. Composite well logs identifying age, formation, completion and lithological profile data are included in Appendix B. Following completion all wells were developed by airlifting, during which time water samples were collected for salinity analysis at Glenside laboratory. Salinity results are presented in Appendix C. All wells were completed for long term observation with a 0.5 m high lockable standpipe cemented over each well.

2.1 SITE NUMBER 1: PTA 115

The monitoring well PTA 115 (unit number 6628 – 20666) was drilled under P/N 56428. The well was drilled adjacent to the section 171, , on the western side of Buckland Road, 250 m north of Park Road. The well was drilled to a total depth of 87.5 m using rotary mud drilling. Sample cuttings were collected at three metre intervals over the entire penetrated depth. Completion of the well was carried out using 142 mm ID class 12 PVC casing from 0.3 m above ground level to 65 m, which was pressure cemented to the surface, with cement 2 m below the casing (67 m), whilst the remaining section of the well (67–87.5 m encompassing the Lower Port Willunga Formation) was left as open hole completion. The well was developed by airlifting from 50 m at a rate of 4–5 L/s for 2 hours, during which time two groundwater samples were obtained from the open hole section in the aquifer for salinity analysis. The electrical conductivity of 1230 uS/cm inferred a total dissolved solids (TDS) content of 677 mg/L, the expected salinity of the T2 aquifer groundwater for this area.

2.2 SITE NUMBER 2: MPA 154

The monitoring well MPA 154 (unit number 6628 – 20729) was drilled under P/N 56853. The well was drilled adjacent to the section 3879, , approximately 20 m southwest of Angle Vale Road on the southeastern side of Frisby Road. The well was drilled to a total depth of 105.2 m using rotary mud drilling. Sample cuttings were collected at three metre intervals over the entire penetrated depth.

Completion of the well was carried out using 142 mm ID class 12 PVC casing from 0.3 m above ground level to 84 m, which was pressure cemented to the surface, with cement 2 m below the casing (86 m), whilst the remaining section of the well (86–105.2 m encompassing the Lower Port Willunga Formation) was left as open hole completion. The well was developed by airlifting from 60 m, at a rate of approximately 6 L/s for 4 hours during which time the well produced a significant amount of fine sand. During airlifting the sand content was decreasing and at the end of 4 hours of airlifting was around 5–10%. Further development was suggested. The well was further developed on the 15th and 16th of May 2002 using a Legra pump set at 80 m. Development began at a flowing rate of 2 L/s for a period of 90 minutes. The first few samples contained approximately 1/3–1/2 of a cup of fine sand per 1.25 litre of water sample, which slowly waned to about 1 teaspoon of sand per 1.25 litre water sample for the last 30 mins of the test (less than 1%). Then the flow rate was increased to 5 L/s, which brought about an increase in the sand content of approximately 1/4–1/3 of the cup of fine sand per 1.25 litre of water sample (~6%), which stayed constant for the duration of the development, being a total of 120 minutes. On 16/5/02; development continued at a flowing rate of 5 L/s for a total of 360 minutes with no sign of the sand content decreasing. No further development was conducted at this stage. Three groundwater samples during initial development and another 34 during further development were collected for salinity analysis. The electrical conductivity of 1190 uS/cm inferred a total dissolved solids (TDS) content of 655 mg/L, the expected salinity of the T2 aquifer groundwater for this area.

2.3 SITE NUMBER 3: MPA 155

The monitoring well MPA 155 (unit number 6628 – 20730) was drilled under P/N 56851. The well was drilled adjacent to the section 3900, hundred of Munno Para, on the southeastern side of Short Road, 150 m southwest of Robert Road. The well was drilled to a total depth of 100 m using rotary mud drilling. Sample cuttings were collected at three metre intervals over the entire penetrated depth. Completion of the well was carried out using 142 mm ID class 12 PVC casing from 0.2 m above ground level to 86 m, which was pressure cemented to the surface, whilst the remaining section of the well (86–100 m encompassing the Lower Port Willunga Formation) was left as open hole completion. The well was developed by airlifting from 50 m, at a rate of 4–5 L/s for 3 hours during which time two groundwater samples were obtained from the open hole section in the aquifer for salinity analysis. The electrical conductivity of 2600 uS/cm inferred a total dissolved solids (TDS) content of 1440 mg/L, the expected salinity of the T2 aquifer groundwater for this area.

The well was drilled adjacent to the section 99, hundred of Port Gawler, on the northern side of Johns Rd, 350 m east of Baker Road. The well was drilled to a total depth of 76 m using rotary mud drilling. Sample cuttings were collected at three metre intervals over the entire penetrated depth. Completion of the well was carried out using 142 mm ID class 12 PVC casing from 0.3 m above ground level to 56 m, which was pressure cemented to the surface, whilst the remaining section of the well (56–76 m encompassing the Lower Port Willunga Formation) was left as open hole completion. The well was developed by airlifting from 50 m, at a rate of 4 L/s for 3 hours, during which time two groundwater samples were obtained from the open hole section in the aquifer for salinity analysis. The electrical conductivity of 1490 uS/cm inferred a total dissolved solids (TDS) content of 821 mg/L, the expected salinity of the T2 aquifer groundwater for this area.

2.5 SITE NUMBER 5: PTG 84

The monitoring well PTG 84 (unit number 6628 – 20732), was drilled under P/N 56847. The well was drilled adjacent to the section 174, hundred of Port Gawler, on the western side of Pederick Road, 30 m north of Hayman Road. The well was drilled to a depth of 51 m and the total loss of circulation occurred between 45–51 m. The well was cased using 142 mm ID class 12 PVC casing from 0.2 m above ground level to 49.8 m and pressure cemented to the surface and than drilled to total depth of 70 m using rotary mud drilling. Sample cuttings were collected at three metre intervals over the entire penetrated depth. The section of the well 49.8–70 m, encompassing the Lower Port Willunga Formation, was left as open hole completion. The well was developed by airlifting from 37 m, at a rate of 4 L/s for 1.5 hours, during which time three groundwater samples were obtained from the open hole section in the aquifer for salinity analysis. The electrical conductivity of 1830 uS/cm inferred a total dissolved solids (TDS) content of 1010 mg/L, the expected salinity of the T2 aquifer groundwater for this area.

The well was drilled to a total depth of 100 m using rotary mud drilling. Sample cuttings were collected at three metre intervals over the entire penetrated depth.

Report DWLBC 2004/57 9 Northern Adelaide Plains Groundwater Monitoring Network Upgrade RESULTS OF DRILLING

Completion of the well was carried out using 142 mm ID class 12 PVC casing from 0.1 m above ground level to 84 m, which was pressure cemented to the surface, whilst the remaining section of the well (84–100 m encompassing the Lower Port Willunga Formation) was left as open hole completion. The well was developed by airlifting from 60 m, at a rate of approximately 5 L/s for 2 hours, during which time the well produced significant amount of fine sand. During airlifting sand content was decreasing and at the end of 2 hours airlifting was around 5%. The well was further developed on 21 of May 2002 using a Legra pump set at 80 m. Development began at a flow rate of 2 L/s for a period of 125 minutes with initial groundwater samples containing approximately 1/4 of a cup of sand per 1.25 litre of groundwater sample (~5%). Groundwater began to clear at about the 90 minutes mark, clearing up to 1 teaspoon per 1.25 litre of groundwater sample within the next 45 minutes. The increase of the flow rate up to 5 L/s brought on the sand at about the same ratio per sample as the first stage (~5%). At 240 minutes the sand content was decreasing and continued to do so up until the end of the stage, at 330 minutes, whereupon the sand content was down to about 1 teaspoon per 1.25 litre of groundwater sample. No further development was required at this stage. Two groundwater samples during initial development, on the well completion, and another twenty one during further development were collected for salinity analysis. The electrical conductivity of 1010 uS/cm inferred a total dissolved solids (TDS) content of 556 mg/L, the expected salinity of the T2 aquifer groundwater for this area.

Completion of the well was carried out using 142 mm ID class 12 PVC casing from 0.3 m above ground level to 78 m, which was pressure cemented to the surface, with cement 1 m below the casing (79 m), whilst the remaining section of the well (79–96 m encompassing the Lower Port Willunga Formation) was left as open hole completion. The well was developed by airlifting from 54 m, at a rate of 4 L/s for 1.5 hours, during which time three groundwater samples were obtained from the open hole section in the aquifer for salinity analysis. The electrical conductivity of 1380 uS/cm inferred a total dissolved solids (TDS) content of 761 mg/L, the expected salinity of the T2 aquifer groundwater for this area.

2.10 SITE NUMBER 10 – REPLACEMENT WELL: MPA 153

The monitoring well MPA 153 (unit number 6628 – 20678), was drilled under P/N 56430 to replace government non-pressure cemented monitoring well MPA 75, which was backfilled under P/N 56429. This replacement monitoring well was drilled adjacent to the section 3889, hundred of Munno Para, approximately 20 m northeast of Curtis Road (3 m north of backfilled well MPA 75). The well was drilled to a total depth of 94 m using rotary mud drilling. Sample cuttings were collected at three metre intervals over the entire penetrated depth. Completion of the well was carried out using 142 mm ID class 12 PVC casing from 0.2 m above ground level to 74 m, which was pressure cemented to the surface, whilst the remaining section of the well (74–94 m encompassing the Lower Port Willunga Formation) was left as open hole completion. The well was developed by airlifting from 52 m, at a rate of 3–4 L/s for 3 hours, during which time three groundwater samples were collected for salinity analysis. The electrical conductivity of 2280 uS/cm inferred a total dissolved solids (TDS) content of 1261 mg/L, the expected salinity of the T2 aquifer groundwater for this area.

2.11 SITE NUMBER 11 – REPLACEMENT WELL: MPA 159

The monitoring well MPA 159 (unit number 6628 – 20736), was drilled under P/N 56849 to replace a government non-pressure cemented monitoring well MPA 64, which was backfilled under P/N 56850. This replacement monitoring well was drilled adjacent to the section 3052, hundred of Munno Para, approximately 50 m southwest of Penfield Road on the southeastern side of King Road (~80 m south of backfilled well MPA 64). The well was drilled to a total depth of 100 m using rotary mud drilling. Sample cuttings were collected at three metre intervals over the entire penetrated depth. Completion of the well was carried out using 142 mm ID class 12 PVC casing from 0.2 m above ground level to 83 m, which was pressure cemented to the surface, whilst the remaining section of the well (83–100 m encompassing the Lower Port Willunga Formation) was left as open hole completion. The well was developed by airlifting from 60 m, at a rate of 4 L/s for 2 hours, during which time three groundwater samples were obtained from the open hole section in the aquifer for salinity analysis. The electrical conductivity of 1730 uS/cm inferred a total dissolved solids (TDS) content of 955 mg/L, the expected salinity of the T2 aquifer groundwater for this area.

Report DWLBC 2004/57 12 Northern Adelaide Plains Groundwater Monitoring Network Upgrade 3. RESULTS OF WELL BACKFILLING

Two backfilled wells had steel casing which was corroded (Fig. 1). They could not be rehabilitated and their backfilling was necessary because their condition deteriorated and they became a risk for the aquifers they were monitoring.

3.1 MONITORING WELL: MPA 75

The monitoring well MPA 75 (unit number 6628 – 2718) was backfilled under P/N 56429 with cement slurry from 112 m to the ground level.

3.2 MONITORING WELL: MPA 64

The monitoring well MPA 64 (unit number 6628 – 2470) was backfilled under P/N 56850 with cement slurry from 129 m to the ground level.

Report DWLBC 2004/57 13 Northern Adelaide Plains Groundwater Monitoring Network Upgrade 4. CONCLUSIONS

The Northern Adelaide Plains T2 Aquifer monitoring network was upgraded by eleven new monitoring wells, nine of which were constructed in new locations, whilst two were constructed on the existing monitoring sites, as replacement monitoring wells. All wells were constructed according to specifications and following completion, nine wells were satisfactorily developed by airlifting. Only two wells (MPA 154 and MPA 156) required further developing for the reason that they were producing a significant amount of fine sand during initial airlifting. These wells were further developed to a satisfactory level (acceptable and practical limits) using the Legra pump. During development the wells were sampled and groundwater salinity (TDS) of all the wells was in the expected range for each respective site. Following completion all wells were surveyed (optically levelled to 3rd order standard with expected accuracy r0.005 m from true) and coordinates were derived from nearby coordinated cadastral marks by use of a Total Station Theodolite but are quoted to the nearest 0.1 m. All monitoring wells data was updated in the SA-Geodata database and Asset Register.

Act (the). In this document, refers to The Natural Resources Management Act (South Australia) 2004. Adaptive management. A management approach, often used in natural resource management, where there is little information and/or a lot of complexity and there is a need to implement some management changes sooner rather than later. The approach is to use the best available information for the first actions, implement the changes, monitor the outcomes, investigate the assumptions and regularly evaluate and review the actions required. Consideration must be given to the temporal and spatial scale of monitoring and the evaluation processes appropriate to the ecosystem being managed. Algal bloom. A rapid accumulation of algal biomass (living organic matter) which can result in deterioration in water quality when the algae die and break down consuming the dissolved oxygen and releasing toxins. Ambient. The background level of an environmental parameter (e.g. a background water quality like salinity). Anabranch. A branch of a river that leaves the main stream. Annual adjusted catchment yield. Annual catchment yield with the impact of dams removed. Aquifer. An underground layer of rock or sediment which holds water and allows water to percolate through. Aquifer, confined. Aquifer in which the upper surface is impervious and the water is held at greater than atmospheric pressure. Water in a penetrating well will rise above the surface of the aquifer. Aquifer, storage and recovery (ASR). The process of recharging water into an aquifer for the purpose of storage and subsequent withdrawal. Aquifer test. A hydrological test performed on a well, aimed to increase the understanding of the aquifer properties, including any interference between wells, and to more accurately estimate the sustainable use of the water resource available for development from the well. Aquifer, unconfined. Aquifer in which the upper surface has free connection to the ground surface and the water surface is at atmospheric pressure. Aquitard. A layer in the geological profile that separates two aquifers and restricts the flow between them. Arid lands. In South Australia arid lands are usually considered to be areas with an average rainfall of less than 250 mm and support pastoral activities instead of broad acre cropping. Artesian. Under pressure such that when wells penetrate the aquifer water will rise to the ground surface without the need for pumping. Artificial recharge. The process of artificially diverting water from the surface to an aquifer. Artificial recharge can reduce evaporation losses and increase aquifer yield. (See recharge, natural recharge, aquifer.) Barrage. Specifically any of the five low weirs at the mouth of the River Murray constructed to exclude seawater from the Lower Lakes. Baseflow. The water in a stream that results from groundwater discharge to the stream. (This discharge often maintains flows during seasonal dry periods and has important ecological functions.) Basin. The area drained by a major river and its tributaries. Benchmark condition. Points of reference from which change can be measured. Biological diversity (biodiversity). The variety of life forms: the different life forms including plants, animals and micro-organisms, the genes they contain and the ecosystems (see below) they form. It is usually considered at three levels — genetic diversity, species diversity and ecosystem diversity.

Prescribed area, surface water. Part of the State declared to be a surface water prescribed area under the Water Resources Act 1997. Prescribed lake. A lake declared to be a prescribed lake under the Water Resources Act 1997. Prescribed water resource. A water resource declared by the Governor to be prescribed under the Act, and includes underground water to which access is obtained by prescribed wells. Prescription of a water resource requires that future management of the resource be regulated via a licensing system. Prescribed watercourse.

It is administered by the International Union for Conservation of Nature and Natural Resources. It was signed in the town of Ramsar, Iran in 1971, hence its common name. The Convention includes a list of wetlands of international importance and protocols regarding the management of these wetlands. Australia became a signatory in 1974. Recharge area. The area of land from which water from the surface (rainfall, streamflow, irrigation, etc.) infiltrates into an aquifer. (See artificial recharge, natural recharge.) Reclaimed water. Treated effluent of a quality suitable for the designated purpose. Rehabilitation (of waterbodies). Actions that improve the ecological health of a waterbody by reinstating important elements of the environment that existed prior to European settlement.

Remediation (of waterbodies). Actions that improve the ecological condition of a waterbody without necessarily reinstating elements of the environment that existed prior to European settlement. Restoration (of waterbodies). Actions that reinstate the pre-European condition of a waterbody. Reticulated water. Water supplied through a piped distribution system. Riffles. Shallow stream section with fast and turbulent flow. Riparian landholder. A person whose property abuts a watercourse or through whose property a watercourse runs. Riparian rights. These were old common law rights of access to, and use of water. These common law rights were abolished with the enactment of the Water Resources Act 1997, which now includes similar rights under s. 7. Riparian rights are therefore now statutory rights under the Act. Where the resource is not prescribed (Water Resources Act 1997, s. 8) or subject to restrictions (Water Resources Act 1997, s. 16), riparian landholders may take any amount of water from watercourses, lakes or wells without consideration to downstream landholders, if it is to be used for stock or domestic purposes. If the capture of water from watercourses and groundwater is to be used for any other purpose then the right of downstream landholders must be protected. Landholders may take any amount of surface water for any purpose without regard to other landholders, unless the surface water is prescribed or subject to restrictions. Riparian zone. That part of the landscape adjacent to a water body, that influences and is influenced by watercourse processes. This can include landform, hydrological or vegetation definitions. It is commonly used to include the in-stream habitats, bed, banks and sometimes floodplains of watercourses. Seasonal watercourses or wetlands. Those watercourses and wetlands that contain water on a seasonal basis, usually over the winter/spring period, although there may be some flow or standing water at other times. State water plan. The plan prepared by the Minister under Part 7, Division 1, s. 90 of the Act. Stock Use. The taking of water to provide drinking water for stock other than stock subject to intensive farming (as defined by the Act). Stormwater. Runoff in an urban area. Surface water. (a) water flowing over land (except in a watercourse), (i) after having fallen as rain or hail or having precipitated in any another manner, (ii) or after rising to the surface naturally from underground; (b) water of the kind referred to in paragraph (a) that has been collected in a dam or reservoir. Taxa. General term for a group identified by taxonomy — which is the science of describing, naming and classifying organisms. To take water. From a water resource includes (a) to take water by pumping or syphoning the water; (b) to stop, impede or divert the flow of water over land (whether in a watercourse or not) for the purpose of collecting the water; (c) to divert the flow of water in a watercourse from the watercourse; (d) to release water from a lake; (e) to permit water to flow under natural pressure from a well; (f) to permit stock to drink from a watercourse, a natural or artificial lake, a dam or reservoir. Total kjeldhal nitrogen (TKN). The sum of aqueous ammonia and organic nitrogen. Used as a measure of probable sewage pollution. Transfer. A transfer of a licence (including its water allocation) to another person, or the whole or part of the water allocation of a licence to another licensee or the Minister under Part 5, Division 3, s. 38 of the Act. The transfer may be absolute or for a limited period. Underground water (groundwater). Water occurring naturally below ground level or water pumped, diverted or released into a well for storage underground. Volumetric allocation. An allocation of water expressed on a water licence as a volume (e.g. kilolitres) to be used over a specified period of time, usually per water use year (as distinct from any other sort of allocation). Wastewater. See domestic wastewater, industrial wastewater.

Water affecting activities. Activities referred to in Part 4, Division 1, s. 9 of the Act. Water allocation. (a) in respect of a water licence means the quantity of water that the licensee is entitled to take and use pursuant to the licence; (b) in respect of water taken pursuant to an authorisation under s. 11 means the maximum quantity of water that can be taken and used pursuant to the authorisation. Water allocation, area based. An allocation of water that entitles the licensee to irrigate a specified area of land for a specified period of time usually per water use year. Water allocation plan (WAP). A plan prepared by a CWMB or water resources planning committee and adopted by the Minister in accordance with Division 3 of Part 7 of the Act. Water licence. A licence granted under the Act entitling the holder to take water from a prescribed watercourse, lake or well or to take surface water from a surface water prescribed area. This grants the licensee a right to take an allocation of water specified on the licence, which may also include conditions on the taking and use of that water. A water licence confers a property right on the holder of the licence and this right is separate from land title. Water plans. The State Water Plan, catchment water management plans, water allocation plans and local water management plans prepared under Part 7 of the Act. Water service provider. A person or corporate body that supplies water for domestic, industrial or irrigation purposes or manages wastewater. Waterbody. Waterbodies include watercourses, riparian zones, floodplains, wetlands, estuaries, lakes and groundwater aquifers. Watercourse. A river, creek or other natural watercourse (whether modified or not) and includes: a dam or reservoir that collects water flowing in a watercourse; and a lake through which water flows; and a channel (but not a channel declared by regulation to be excluded from the this definition) into which the water of a watercourse has been diverted; and part of a watercourse. Water-dependent ecosystems. Those parts of the environment, the species composition and natural ecological processes, which are determined by the permanent or temporary presence of flowing or standing water, above or below ground. The in-stream areas of rivers, riparian vegetation, springs, wetlands, floodplains, estuaries and lakes are all water-dependent ecosystems. Water-use year. The period between 1 July in any given calendar year and 30 June the following calendar year. This is also called a licensing year. Well.

Wetlands. Defined by the Act as a swamp or marsh and includes any land that is seasonally inundated with water. This definition encompasses a number of concepts that are more specifically described in the definition used in the Ramsar Convention on Wetlands of International Importance. This describes wetlands as areas of permanent or periodic/intermittent inundation, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh, brackish or salt, including areas of marine water the depth of which at low tides does not exceed six metres.
