Description
The hydrogeology of a 68 000 km2 region of arid central Australia has been assessed and mapped at 1:500 000 scale using a GIS to interpret various spatial data sets and compile statistics of water bore information. This work forms a part of the Western Water Study, a collaborative venture between Federal, Territory and Aboriginal representative agencies, which has the objective of improving access to groundwater information for Aboriginal people on their land. The study area is underlain by Proterozoic basement (Arunta Block), pre-Mesozoic sedimentary basins (Amadeus and Ngalia Basins) and Cainozoic sediments. Based on the analyses of 850 water bores , the study area is mapped as seven different aquifer systems to cover regional variations in hydrogeology. Palaeodrainages act as a sink along which groundwater drains to associated internal discharge playas. Statistical groundwater data for these systems and the individual geological formations drilled provide a starting point for further groundwater assessment in other areas of central Australia that have similar geology. Only one aquifer system representing about 3% of the study area in Cainozoic sediments along a mountain range consistently provides low salinity < 1000 mg/L) potable groundwater, though potable water can occasionally be found elsewhere throughout the region. Large individual bore yields of over 20Us can be found in the pre- Mesozoic and Cainozoic systems while a lack of storage precludes sustained high yield production from bores in the Proterozoic.

Data Quality
Lineage:The data is a collation of new and existing datasets.
The data sets included in the Western Water Study GIS are described elsewhere by Wischusen et al. (1997). Other aspects of the Western Water Study have previously been reported: Woodcock et al. (1997) discussed remote sensing data interpretation; English (1997) looked at major lineaments over the region and their influence on groundwater prospects; Gallagher (1996, 1998) reported on specialized applications of the GIS and how they may be useful elsewhere; and Macphail (1997) presented Cainozoic palynological data. Several special 1:500 000 geological maps over the Western Water Study region have been compiled: Lau (1997) has compiled a geology map; Lau et al. (1997) a Cainozoic geology map; and Lau and Shaw (1997) a solid geology map. In addition, Toyne et al. (1997) reported on the consultations with Aboriginal communities in the region and outlined a proposal for bicultural water management committees. Hostetler et al. (1998) reported on groundwater quality in the region and Cresswell et al. (1998) discussed aspects of isotope hydrology in the region.
All the information outlined above has been used to some degree in defining and delineating the Aquifer Systems of the Western Water Study region, and the GIS was found to be a very useful tool for classifying large bore data sets and tabulating drilling and chemistry data. There is no drilling data for extensive parts of the study area, and therefore much of the interpretation is based on extrapolation.
Positional Accuracy:Positional accuracy of 500 metres from bore locations.
Attribute Accuracy:Attributes assigned according to the dominant feature. For example, several similar geological units have been grouped to describe a particular geology. Several bore sites describing yield or chemistry information have been grouped to describe a particular hydrology. From the geology and hydrology information the hydrogeology units was delineated.
Logical Consistency:GIS editing tools were used to rectify all overshoots and undershoots in line work. Polygon topology rules applied are must not overlap, must not have gaps and each polygon has only one label
Completeness:Complete
