Chemical analysis has identified the Cadia Hill goldmine as a potential source of some of the lead found in samples collected from nearby residential rainwater tanks in central west New South Wales, the mine's management has said.

The NSW Environment Protection Authority has been investigating the goldmine - one of the largest in the world - since May, when it issued Newcrest's Cadia Holdings Pty Ltd with a draft pollution prevention notice and a draft licence variation regarding its management of emissions of dust and other pollutants. It followed local residents, including children, reporting heavy metals in their blood and rainwater tanks.
