Abstract
Enhanced biodegradation using carbon donor and microbial addition is being considered as a possible remediation technique for a trichloroethylene (TCE) contaminated area in Sunset, Utah, west of the source area on Hill Air Force Base. As a precursor to any in situ remediation attempts, several laboratory treatability experiments are being conducted, including the construction of microcosms and flow-through columns. Nine large-scale flow-through columns were built using site groundwater and aquifer material. Bromide tracer tests were conducted to establish and understand the hydraulic conditions within the columns prior to the commencement of the TCE biodegradation experiments. Four predictive models were created to show potential degradation scenarios in the columns and in the field using microcosm data for various system treatments. Treatments selected for modeling indicated that carbon addition alone is insufficient in stimulating dechlorination of TCE. Microbial amendments will be necessary in the column systems when the TCE dechlorination experiments begin.
