Sydney water catchment laced with toxins

WATER flowing into a river that feeds Sydney's drinking water supply is laced with metals and poisons including arsenic, copper and boron, a university researcher says.
The poisons have been seeping from a coal-fired power station near Lithgow, in the Blue Mountains.
The Department of Environment and Climate Change says it knows about the discharge from Wallerawang power station, and is reviewing research by the University of Western Sydney which indicates "a large and unnatural increase above natural background arsenic levels in the upper Cox River catchment''.
The university's Ian Wright said the arsenic was diluted downstream and is not thought to pose a human health risk, Fairfax Media reports.
Copper was measured close to the power station at between 30 and 50 times natural levels, and boron levels were 25 times higher than upstream.
Dr Wright's research will be used in a case to be put before the Land and Environment Court, which will argue Delta Electricity is polluting the Cox River and should be made to stop.
