AbstractAbstract
[en] Area F is a storage site at CRNL for 119 000 tonnes of soil contaminated with low levels of arsenic and radium-226. The site was closed in 1979, and a clayey silt cover was installed in an attempt to minimize infiltration of available precipitation. Results of studies in 1980 and 1983 are used to show that the low-permeability cover has been largely ineffective in reducing infiltration. Radium has remained immobile, but arsenic is being transported by infiltrating waters into unsaturated sands beneath the contaminated soil. Iron oxyhydroxide coatings on the sand grains are sorbing the transported arsenic, and have reduced dissolved arsenic concentrations in pore waters in the sands to natural background levels
