The Queensland Opposition has warned any resumption of uranium mining near Townsville in the state's north risked contaminating the city's water supply.
The State Government recently announced plans to resume uranium mining across Queensland.
The Ben Lomond uranium mine, 50 kilometres west of Townsville, closed more than 20 years ago amid serious environmental concerns.
The mine is in the Thuringowa electorate of Liberal National Party (LNP) MP Sam Cox.
Deputy Opposition Leader Tim Mulherin today called on Mr Cox to become more involved in any proposals to reopen the mine.
Mr Mulherin says nearby residents needed a guarantee environmental concerns do not still exist.
"The concerns related to the tail dams, cyclonic rain events and the impact the heavy metals and radioactive materials," he said.
Mr Mulherin says when the mine was closed there was concern radioactive tailings would reach the Burdekin River, which supplies water to the Townsville region.
The ABC has approached Mr Cox for comment.
