Abstract: The distribution of δ¹³C values,⁸⁷Sr/⁸⁶Sr ratios, and¹⁴C activities (a¹⁴C) show that considerable inter-aquifer flow occurs in the Wimmera Region of the Murray Basin, southern Australia. Many of the potential aquitards, (e.g., Bookpurnong Beds and Ettrick Marl) are ineffective barriers to groundwater flow; only the Geera Clay forms an effective aquitard and restricts inter-aquifer leakage between the Loxton-Parilla Sands and/or the Murray Group and the underlying Renmark Formation. This study illustrates the utility of environmental isotopes in determining inter-aquifer flow and aquitard effectiveness in regions where direct studies of aquitards is lacking.
