According to the Environmental Protection Agency's TENORM Report, "Water is perhaps the most significant means of dispersal of uranium and related [radioactive materials] in the environment from mines and mine wastes…Uranium is very soluble in acidic and alkaline waters and can be transported easily from a mine site." This is of great concern. If Virginia allows uranium mining, it would be the first state to do so in the United States in a climate where rainfall exceeds evaporation.
Water is used (and contaminated) in the milling process. In addition, rain falling on waste products from the mining and milling processes picks up radioactive and other toxic elements which can end up and remain in surface and ground waters for thousands of years. In the 1980s, Marline Uranium estimated that the waste pile from their proposed Virginia operation would cover 930 acres, 100 feet deep.
At the recently proposed Coles Hill uranium mining site in Pittsylvania County, there will be hundreds of acres of radioactive waste and millions of gallons of water contaminated in the mining and milling processes. To mine uranium safely, hundreds of millions of gallons of contaminated and radioactive water will have to be prevented from running into Virginia streams or leaching into the ground water. Virginia's most populous communities lie downstream of the uranium leases filed in the 1980s.
Virginia's Acute Rainfall Events
Not only does the Virginia Piedmont have greater annual rainfall than other uranium mining communities, it also has greater acute rainfall events. Two of the top five most intense 12-hour storms in the United States occurred in the Virginia Piedmont.
Twenty-seven inches of rain fell on Nelson County in 1969. Twenty-nine inches fell in Madison County in 1995. Significant flooding also happened in Pittsylvania County in 1996 during Hurricane Fran.
As noted by Elizabeth Haskell in her dissent to the recommendation of the Uranium Subcommittee/Uranium Administrative Group: "In Virginia's wet climate where water is discharged from the site and filters through tailings, the transmittal of radiation to people through streams and the groundwater is a major issue."
Such a risky experiment should not be conducted on Virginia. Virginia should take no action to initiate or sanction a study of uranium mining until the proponents of mining provide reviewable information demonstrating that mining and milling have been undertaken in five places with climate, geology, and population density similar to Virginia and in such a manner as to safeguard the environment, natural and historic resources, agricultural lands, and the health and well-being of citizens of those communities.
