Contamination of groundwater by chlorinated compounds such as trichloroethylene (TCE) is an environmental concern due to their high level of toxicity and potential impact on drinking water [1]. It is estimated that TCE is present above permissible levels in 9-34% of drinking water sources in the U.S [2]. Thus, development of a remediation system to remove chlorinated compounds from groundwater has become imperative. Existing remediation techniques for treatment of contaminated water are not efficient or feasible due to low rates of remediation, high energy inputs, and media regeneration/replacement cost. [3, 4]. Although hydrodechlorination (HDC) appears to be an efficient way of groundwater remediation, it suffers kinetically due to low concentration of contaminants and catalyst deactivation due to anionic groundwater constituents [5, 6].
