PH8’s unique water source was discovered 130 years ago by Chinese workers that operated a lime kiln on the property now known as Old Lime Kiln Farm. The locals confirmed a long known secret by farmers that the water quality at the Old Lime Kiln Farm was different to the surrounding aquifer of the Yorke Peninsula. Scientific tests confirmed this, with the property covered by black limestone thought to be laid down more than a billion years ago.

PH8 Natural Alkaline Water is drawn from an aquifer which is found between 17 and 38 metres below the surface. It takes some 12 – 14 months for the plentiful annual rainfall to seep through the black limestone. This natural filtration is how PH8 gathers its unique properties and incredibly smooth taste.

With an alkaline pH of 8 from the source, the natural alkalinity and essential trace minerals offers a range of health benefits and fast hydrating effect. These properties render PH8 as one of the finest drinking waters in the world, when compared to other world renowned water analyses.
