Title

Enhancement of in situ zero-valent metal treatment of contaminated groundwater

Abstract

Groundwater contamination by chlorinated solvents has been found at many sites. An innovative technique which has been the topic of numerous studies uses zero-valent metals to promote the reductive dehalogenation of chlorinated hydrocarbons. The purpose of this study was to evaluate the combined effects of sonication and zero-valent metal on the rate of destruction of chlorinated hydrocarbons. If degradation rates can be enhanced, reaction times will be reduced for equivalent final contaminant concentrations. Consequently, reactor size can be reduced in the application of this technology to field-scale projects, significantly decreasing treatment cost. Comparison of half-lives of trichloroethene when treated with iron suggests that the addition of ultrasound increases reaction rates more than three-fold over use of iron alone.
