The Authority currently operates a number of mine water treatment schemes in order to remediate existing discharges and prevent new discharges from coal mine workings. This programme prevents 2,900 tonnes of iron discharging into the nation's water courses and has improved 120 kilometres of water course and prevented new discharges into approximately 200 kilometres of water courses.
