Acid drainage from the abandoned base-metals mine at Captains Flat, New South Wales, is the main contributor of zinc to the Molonglo River in low flow conditions. In 1982, zinc was detectable in the river for 50 km downstream of Captains Flat. Rehabilitation works at the mine site have effectively stabilised tailings dumps, and neutralised them as a source of major pollution.
