Aquifer interactions and their impact on groundwater resources in the Basalt plains of Western Victoria, Australia
South of the West Victorian Uplands in southeastern Australia, a series ofpalaeorivers (so-calleddeep leads), buried beneath 30-120 m of basalt, form a complex aquifer system (the Streatham Deep Lead System) which extends over an area of more than 2500 km2. Groundwater quality both within the unconfined basalt aquifer and the deep lead aquifer ranges from high (suitable for human consumption) to very saline.Combining analyses of several natural environmental isotopes with hydraulic data show that the two aquifers are separated over much of the area. However, preferential recharge to the deep lead system occurs through eruption points, resulting in good quality groundwater in both aquifers in these areas.
