Analyses of pumping tests performed on a semi-confined aquifer of the Knight Group in the Hundred of Mingbool indicate that the coefficient of permeability of the confining bed is approximately 0.015 metres3 day-1 metre-2. Values of transmissivity and...

The development and testing of the Beachport Town Water Supply Bore No. 2, was badly handicapped by incorrect screen selection, an apparently insensitive pressure gauge, and incomplete development of the bore prior to testing. The transmissivity of...

Three bores were drilled at Robe to develop an additional town water supply and to investigate salinity and the extent of hydrogen sulphide contaimination. An aquifer test of 12 hours duration gave a value of transmissivity of 2,424 metres 3/day/metre...

Apcel Pty Ltd. have investigated a number of disposal sites for paper industry waste in the general vicinity of their Snuggery plant. The quarry in volcanic ash and associated volcanics at Mount Watch is one such site. Although the nature, volume,...

Analyses of two pumping tests conducted on the Knight Formation water supply bore on the property of Wattie Pict Ltd. at Mount Gambier suggest transmissivities of 1,600 metres/day/metre and 180 metres3/day/metre respectively for the early and late...

Tarpeena township has been provided with a reticulated water supply from the upper Knight Group aquifer. Two bores 15 m apart have been constructed and fully equipped, one of them for standby purposes. The safe yield of the supply bore is 20...

The Beachport Town Water Supply No. 3 was flow-tested using a series of orifice plates. The testing programme consisted of a main test and five stages in a flow recession test. The orifice plates were used not to measure flow rate, but to ensure a...

The Mount Gambier area of south-eastern South Australia is totally dependent upon groundwater for its water supplies. Water of low salinity is extracted from an unconfined aquifer (the Gambier Limestone) and, to a much lesser extent, confined aquifers...

A 203 mm diameter bore was drilled to a depth of 179 m in Section 565, Hundred of Mount Muirhead to augment the Millicent town water supply. The average pumping rate during the main 72 hour test was 46.3 litres/sec. with a maximum drawdown of 16.60 m....

An exploratory town water supply bore and an observation bore were sunk on Section 722 Hundred of Wirrega for the township of Mundulla. A 72 hour aquifer test gave a value for Transmissivity (T) of 800 m3/day/m and a Storage Coefficient of 0.08 for...

A new well, Kingston No. 10, was drilled on section 504, hundred of Lacepede to augment Kingston's water supply. A flow of water (5 1/sec) was obtained after intersecting Kongorong Sand at 86m. Subsequent well testing showed it to have a safe yield of...

To establish a potable water supply for Carpenter Rocks, two production bores were drilled in section 500, hundred of Kongorong. The first was drilled 350m inland from the coast and was later abandoned due to high salinity, presence of hydrogen...

Following pollution of the Gambier Limestone aquifer by subsurface waste disposal, a production bore for Kraft Foods at Mil-Lel was drilled into the Knight Group. To increase the limited knowledge of this confined aquifer, a Departmental observation...

Results of an aquifer test carried out at APCEL Pty. Ltd. in mid January, 1976 and a review of previous drilling and hydrogeological investigations in the Millicent - Snuggery area have shown the Gambier Limestone to consist of an upper phreatic...

Reverse air circulation rotary drilling of four outcrops of potentially glass-grade raw material dolomite rock (42 holes for a total penetration of 924 m), carried out 14 km north-west of Mount Gambier in April 1989 on a 50 m grid within pine...

The Naracoorte Ranges Prescribed Wells Area (PWA) is 300 km SE of Adelaide, and covers about 2400 square km. The PWA consists of a low-lying interdunal flat in the SW, and an elevated highlands area in the NE, separated by the Kanawinka Fault. The...

Numerical modelling of the hydrogeology in the area south of Mount Gambier was used to examine the potential of increasing the Permissible Annual Volumes of extraction for the unconfined aquifer, beyond the levels of assessed vertical recharge to the...

The Lacepede-Kongorong Prescribed Wells Area (PWA) is the largest in the South-East, extending from the Coorong to Port MacDonnell, and from the coast to the boundaries of the adjoining Padthaway, Naracoorte Ranges and Comaum-Caroline PWAs. It covers...
