IN SITU SEQUENTIAL TREATMENT OF A MIXED CONTAMINANT PLUME

Sandy field experiment is polluted by cleaning solvents and waste petroleum hydrocarbons. Design of the funnel-gate structure with aerobic treatment method via two sparge units. Description of field sampling and anatycal methods. Laboratory columns study was conducted to measure the DCE and VC degradation rate constants. A microcosm experiment was conducted to investigate the potential for contaminant biodegradation in the biosparge unit for toluene , DCE and VC degradation. The overall performance of the funnel-gate was assessed by comparing the effluents concentrations against the influent criteria. Summary of the mass removal for chlorinated ethane.
