An expert advising the New South Wales Environmental Protection Authority on Cadia Hill goldmine has raised concerns about the adequacy of its dust regulations imposed on the mine.

The EPA began investigating the goldmine in May after dozens of local residents reported elevated levels of heavy metals in their drinking water. It established an expert panel on 30 June which included Dr Ian Wright, an academic at Western Sydney University, who was involved in the first few rounds of community water testing.
