Dr Wright presented the findings of his past 12 months of research at a public meeting at council on September 27.
He said since the mine had ceased operation, the levels of nickel, zinc and maganese in the water discharged from the mine had increased and polluted the river.
He said this was a problem that could be fixed but it was one many mining companies did not want to address if they didn’t have to.
The Boral spokesperson said the company continued to work with the authorities as well as experts such as Dr Wright to ensure the mine is closed in a manner that meets all government requirements.
“Given the ongoing nature of the water quality investigation and testing process, the complex geological, catchment and legacy issues, it is our belief that a public presentation on the data requested would be premature.
He said the EPA’s environmental protection licence which Boral had complied with was ineffective and the issue had flown under Water NSW’s radar.
Looking at the proposed Hume Coal mine, Dr Wright said if approved it too would have a negative effect on the environment and increase water pollution.
“Dr Wright’s submission is based on a false assumption that the Hume Coal project will discharge large volumes of untreated mine water,” he said.
