摘要

Common remediation options for hazardous waste sites include in-situ and ex-situ technologies. Contaminant removal by excavation, above-ground treatment, or in-situ treatment enhanced by chemical addition has the advantage of good process control, but suffers from high construction, operation, and ultimate disposal costs. Traditional in-situ treatment methods lack process control, but are potentially less expensive. To reduce cost and improve contaminant removal without compromising process control, a third remediation strategy, a down-borehole permeable reactor, was developed. The down-borehole reactor is a passive, in-situ, permeable biological reactor that allows the introduction of nutrients and other chemicals to a subsurface biological population. Equipped with sensors, nutrient delivery, and mixing systems, the reactor is installed in a large diameter well screened over an interval of the contaminated aquifer. Biodegradation of the aqueous phase organic compounds occurs over the length of the reactor in a combination of anaerobic and aerobic biological zones. The goal of this research is to demonstrate the applicability of a permeable barrier for the bioremediation of groundwaters contaminated with pentachlorophenol (PCP). The ultimate goal is to develop this technology for the treatment of groundwaters contaminated with complex waste mixtures.
