Release of Electron Donors during Thermal Treatment of Soils

Thermal treatment of soil and groundwater may provide an in situ source of soluble organic compounds and hydrogen (H2) that could stimulate microbial reductive dechlorination (MRD) at sites impacted by chlorinated solvents. The objectives of this study were to identify and quantify the release of el...

Description
Summary:Thermal treatment of soil and groundwater may provide an in situ source of soluble organic compounds and hydrogen (H2) that could stimulate microbial reductive dechlorination (MRD) at sites impacted by chlorinated solvents. The objectives of this study were to identify and quantify the release of electron donors and fermentable precursors during soil heating and to estimate availability of these compounds following thermal treatment.
