Fresh Cheese Whey Application for Enhanced Anaerobic Bioremediation of Low Levels of Chlorinated Ethenes(Abstract)

摘要

Cheese whey is a soluble electron donor with growing number of applications for enhanced anaerobic bioremediation (EAB) of chlorinated ethenes such as trichloroethene (TCE). EAB applications with cheese whey in the fresh liquid (～ 6% by weight organic carbon) and dry powder (～ 60% by weight organic carbon) forms have been reported. This paper will present the results and discuss the treatment effectiveness of fresh cheese whey injection for EAB of low levels of chlorinated ethenes in shallow ground- water immediately downgradient of source area at a Superfund site. The objectives of this cheese whey application, as part of the ongoing EAB pilot program, are to support the proposed amendment to this Superfund site’s Record of Decision from groundwater pump and treat to in situ bioremediation and attainment of background concentrations.
