VIRGINIA BEACH, Va. (AP) -- A Virginia Beach study says a proposed uranium mine in Pittsylvania County could temporarily contaminate the city's water supply if a hurricane or tropical storm causes massive flooding.
Media outlets report that the city released the study by Michael Baker Corp. on Tuesday.
The study found that Kerr Reservoir upstream of Lake Gaston would trap up to 90 percent of radioactive waste. But the remaining contaminants could enter the lake.
City engineer Tom Leahy says it could take two months to two years to completely flush radioactive contaminants out of Lake Gaston.
Virginia has had a moratorium on uranium mining since 1982. Before uranium can be mined in Virginia, the General Assembly would have to lift the ban.
