In situ remediation of ground water contaminated with chromate and chlorinated solvents using zero-valent iron: A field study

A small-scale field test was recently initiated to evaluate the in situ remediation of ground water contaminated with chromate and chlorinated organics using a permeable reactive barrier. The barrier was composed of an iron metal-coarse sand-native aquifer solid mixture, and was installed using a staggered {open_quotes}fence{close_quotes} design through large hollow-stem augers. The objectives of the project were to evaluate the ability of the cylinders or {open_quotes}fence posts{close_quotes} to remove contaminants from solution immediately downgradient and adjacent to the iron cylinders, evaluate the resultant changes in aqueous geochemistry induced by the presence of the zero-valent iron, and identify chemical, physical and biological processes which may affect long-term performance of such remedial technologies.
