Research Project: Chromium Oxidation-Reduction in Soils: Relevance to Chromate Contamination of Groundwater of the Northeast United States.

Research Faculty: Bruce James.

Hexavalent Cr contamination of natural waters of the northeastern United States is a problem of increasing concern near historic industrial waste disposal and Superfund sites, especially where soils can oxidize insoluble, nontoxic Cr(III) and release it to subjacent groundwater as soluble, toxic Cr(VI) anions. If soil conditions do not favor reduction of Cr(VI) to Cr(III), then gradual, long-term pollution of groundwater and surface water bodies by Cr(VI) may occur at such sites. To address current groundwater contamination problems and to prevent future occurrences, the proposed research will provide new knowledge and a refined understanding of the oxidation-reduction controls on Cr valence state and solubility in diverse soils of the Northeast region.
