The EPA says it launched an investigation after routine testing in March last year by Santos of groundwater around the project - which remains in the test well stage - detected elevated levels of total dissolved solids and slightly elevated levels of other elements. The investigation concluded there was no evidence contractors engaged by the previous owner of the project, Eastern Star Gas, followed strict rules when building a pond to hold waste water and brine produced when gas is extracted. The investigation concluded the pond liner was of poor quality, which resulted in the integrity of the liner being questionable. On Friday, EPA chief environmental regulator Mark Gifford confirmed the contamination was caused by water leaking from the pond and that lead, aluminium, arsenic, barium, boron, nickel and uranium had been detected in an aquifer at levels elevated when compared to livestock, irrigation and health guidelines.
