The Musgrave Proclaimed Wells Area (PWA) contains a number of groundwater lenses of potable quality surrounded by brackish to saline groundwater. Conventional hydrogeological techniques combined with hydrochemistry, environmental isotopes and transient electromagnetic (TEM) methods were used to evaluate the groundwater resources of the region. The TEM method was found to be useful in delineating basement topography but less effective in discriminating groundwater salinity because of its inability to differentiate between saline groundwater and clay within the aquifer matrix. Both hydrochemical and TEM data were able to prove that groundwater is contained within local flow systems of limited lateral extent. This has important implications in terms of long-term or sustainable approach to the management of the resource.
