Degradation of tce
WebMicrocosm studies have been concluded to compare the rate of degradation of PCE, TCE, and cis-DCE in sediment containing magnetite. The first order rates of degradation are slow (0.3 to 1 per year in material with 0.2 percent to 0.4 percent by weight magnetite), but are useful for MNA in many plumes of contaminated ground water. (Ferrey, Webbest degradation occurred with 24–51% removal of each. For these degradation reactions, 39–85% of the stoichio-metric chloride expected from complete degradation of the chlorinated ethenes was detected. The time course of PCE/TCE/1,1-DCE degradation was also measured for a mixture of 8, 17, and 6 µM, respectively; initial degrada-

However, this process is often incomplete, and thus cDCE and vinyl chloride (VC) accumulate in aquifers and aquitards ( Puigserver et al., 2016a ).
