Abstract
Abstract Aqueous extracts from a calcareous spodosol were used as the primary substrate to study the reductive dechlorination of tetrachloroethene (PCE). A comparison was made between extracts obtained using pure water and water saturated with trichloroethene (TCE). The latter solutions were intended to simulate solutions formed by rainwater percolating through TCE‐contaminated soils. The results indicated that TCE‐saturated water apparently mobilized more organic materials than did pure water. The extracts obtained from TCE‐saturated water were noticeably more turbid than those obtained using pure water, suggesting greater mobilization of colloids. After centrifugation, the extracts contained similar amounts of dissolved organic carbon (DOC), 16 and 20 mg/L, respectively. Microcosm studies indicated that both centrifuged extracts were capable of sustaining reductive dechlorination of PCE as evidenced by the production of TCE, dichloroethene (DCE), and methane. These results indicate that the inclusion of...
