200m below your feet across the Adelaide basin lies the Willunga formation. A limestone body containing an aquifer known as T2 or the Willunga aquifer. At the 'Charity Water Fountain' for a gold coin you can fill up any container with water from the aquifer. The same water is used to make a local beer (so it must be good!).
The brewery uses four wells that tap into water in the Willunga Aquifer 200 metres below the site. The water is always pure and of consistently high quality. The result of gradual filtration through a limestone formation over thousands of years from water infiltrating in the Mt Lofty ranges.
Technical Details
T2 Aquifer consists of a large, water bearing layer of well-cemented lower Port Willunga tertiary limestone, 160 to 220m deep, 60m thick. The interface between T1 and T2 is a impermeable layer of clay.
Please visit the earthcache site, take a sample of the water, and answer the following questions.
-Describe the water condition. Clear? Salty? Odour? Chlorinated? Fizzy?
-Tastes like...?
-Do you think it will make good beer?
