Description:
The detection of significant levels of halogenated ali- phatic contaminants in groundwater resources in the U- nited States (1, 2) has spurred a considerable effort to understand the various mechanisms-both microbiological and abiotic-by which these compounds may be trans- formed. In aerobic environments, the abiotic reactions that predominate are elimination of hydrogen halide (dehy- drohalogenation) and nucleophilic substitution by HzO (hydrolysis). Little research has examined the rates and pathways of abiotic reactions that may be significant under hypoxic conditions [ i.e., environments containing very low or undetectable concentrations of 02(aq)]
