Small-scale chemical tracer tests were conducted at two sites in the Clare Valley (Wendouree Winery and Watervale Oval) to investigate the potential for aquifer storage and recovery (ASR) of excess surface runoff water into fractured rock aquifers. At both sites, water tagged with known concentrations of non-polluting tracers was injected into small (up to 5 m thick), isolated sections of the aquifer and allowed to reside and mix with the groundwater there for a period of time before extraction. At the end of each test, when an amount of groundwater equal to three to four times the injected volume had been extracted, it was found that between 50-80% of the injected tracer mass was being recovered from the aquifer. Of the two sites, a higher tracer mass recovery was achieved at Watervale Oval, due to the relatively lower hydraulic conductivity at that site. In general, though, high rates of natural groundwater flow in these and most other fractured rock systems means that recovery efficiencies may be low, particularly for much larger scale developments. The better - suited sites for developing ASR in the Clare Valley are likely to be in areas of high quality groundwater, and should not be adjacent to ready-acting natural discharge features such as deeply incised creek valleys.
