Impacts of Enhanced Reductive Bioremediation on Post-Remediation Groundwater Quality

Abstract

Electron donor (ED) addition can be very effective in stimulating enhanced reductive bioremediation (ERB) of a wide variety of groundwater contaminants. However, ERB can result in Secondary Water Quality Impacts (SWQIs) including decreased levels of dissolved oxygen, nitrate, and sulfate, and elevated levels of dissolved manganese, dissolved iron, methane, sulfide, organic carbon, and naturally occurring hazardous compounds (e.g., arsenic). Fortunately, this plume of impacted groundwater is usually confined within the original contaminant plume and is unlikely to adversely impact potable water supplies. This report presents the results of research performed on this topic as part of project ER-2131 Numerical Modeling of Post-Remediation Impacts of Anaerobic Bioremediation on Groundwater Quality.
