摘要

Laboratory and field studies have established the environmental relevance of the reductive dechlorination process for remediating chlorinated ethene-contaminated sites. This scientific understanding has enabled "intelligent design" engineering of subsurface environments and improved our ability to successfully remediate field sites. However, redox conditions at chlorinated ethene-contaminated sites can range from highly reducing anoxic to relatively oxidized anoxic to oxic. Consequently, researchers and practitioners should recognize the biases introduced by establishing highly reducing conditions and should continue to explore those alternative detoxification pathways that may predominate under relatively oxidized anoxic conditions. Ultimately, comprehensive knowledge of all metabolic pathways affecting chlorinated ethenes is desirable and will provide practitioners additional remediation options. To ensure the transfer of knowledge, however, the results of specific scientific studies must be accurately communicated using explicitly defined language because "anoxic" is different from "reducing," and the distinction has important consequences for assessing and remediating chlorinated ethene-contaminated sites.
