Murray Bridge Abattoir's effluent is being disposed through drainage wells into unconfined aquifers which are hydraulically connected to the Murray River. Six rotary wells encircling the abattoirs area, proved the regional hydraulic gradient to be...

Within the Angas - Bremer Irrigation Area, the source of the groundwater being taken currently primarily for the large-scale irrigation of lucerne fodder crops is the confined low salinity Tertiary limestone aquifer. The extent of pumping from bores...

Investigations in the Hindmarsh Tiers Basin have shown that there is no direct evidence for depletion of groundwater, although summer pumping casues 5 to 10 metre drawdowns near the centre of the area. The main aquifer, a Tertiary bryozoal limestone,...

Land snails - Bothriembryon praecursor andMeracomelon lloydi' from the type section of Etadunna Formation at Lake Palankarinna and freshwater species of Syrioplanorbis,Physastra' and `Rivisessor' from dolomitic limestones near Billa Kalina and...

Compilation of geological sections is from 30 widely scattered localities in Pleistocene to Holocene blanket sequence of fluvial-aeolian deposits. They record the youngest events in the development of the Lake Eyre Basin.

Ancient features in crystalline basement and resurgent tectonic structures post-dating the Delamerian Orogeny controlled the pattern of Upper Palaeozoic, Mesozoic and Cainozoic sedimentation in the Great Australian Basin. This study describes the...

Flint occurs in 4 geological settings in the South-East - beds and dykes in the Gambier Limestone, bouldery conglomerate of the Bridgewater Formation, Holocene surface lag deposits and Holocene beach deposits. Pebbles from beach deposits between Cape...

Observations of karst events at Old Homestead Cave on the Nullarbor Plain add further evidence for a regional, post-emergence Nullarbor karst history or succession of events. Litho-stratigraphy and facies have exerted a control on dissolution and...

For the past 30 years or more, much of the town water supply for Orroroo has come from wells that are completed in the confined aquifer of the Walloway Basin. The unconsolidated, fine, silty sands of this aquifer become mobile and have led to a...

Further investigations have been undertaken within certain areas along the State Border of South Australia and Victoria to assess both vertical groundwater recharge rates and their spatial variability, based on surficial geology, groundwater and land...

A regional groundwater model has been constructed of the Loxton Sands watertable aquifer in the eastern Riverland, over an area extending eastwards from Overland Corner to the State border. It is being used to quantify the salt load impacts on the...

Aquifer storage and recovery (ASR) is being developed as a solution to provide an emergency town water supply in a location where blue- green algae make River Murray water unfit for domestic use during summer. Algae-free river water will be injected...

Dryland salinisation is degrading land and water resources of Lower Eyre Peninsula. It decreases land production capabilities, water quality, and the general aesthetics of the environment. Interdepartmental investigations into the occurrence and...

The Oak Valley Community requires a more convenient water supply. If potable groundwater cannot be found then a supply suitable for purification must be found. Current requirements are a supply of 1 L/s of water of salinity not greater than 40 000...

Aquifer storage and recovery investigations at well 6628-16623 drilled by MESA in The Paddocks wetland storm water treatment and holding site in the Salisbury Council area (Adelaide, South Australia) have been successfully completed. The work...

Reconnaissance sampling of Mesoproterozoic Hiltaba Suite granite on northern Eyre Peninsula, to identify all potentially quarryable granite varieties, was carried out by MESA during 1996/97. A total of 157 outcrops were inspected and 99 samples...

An aquifer storage and recovery scheme is being developed at Clayton township on Lake Alexandrina, South Australia, notably as a solution to provide a town water supply in a location where blue-green algae make River Murray water (extracted via the...

The aquifer storage and recovery scheme at the Regent Gardens housing development became operational during 1995. Water quality monitoring of the wetland/detention basin was undertaken to determine the relationship between turbidity, suspended...

Aerial photography and satellite imagery, plus an on-ground geological reconnaissance and a transient electromagnetic geophysical survey, were used to select sites for drilling water wells to provide a major expansion of the Pukatja town water supply....
