Remediation programme in the North Bohemia region
Description
The Bohemian Massif belongs to a very important uranium province where mining activities started in 1840. Since the end of World War II large mining operations have taken place resulting in a large accumulation of waste dumps and tailings. In 1969, the Straz sandstone type uranium deposits were exploited by in situ leaching methods. 3.8 million tonnes of H2SO4, 270,000 tonnes of HNO3 and 103,000 tonnes of NH4 were injected into the Cenomanian aquifer. It affects 188 million cubic metres of water and 28 km2. The problem is compounded by the presence of an underground mine next to the Straz deposit. The paper describes the environmental remediation programme established by the government. The present estimation of the time necessary for the decontamination of the Straz deposit lies between 50 and 70 years. (author). 5 refs, 5 figs, 1 tab
