Champion International Superfund Site, Libby, Montana Field Performance Evaluation. Bioremediation Unit: 'In situ' Bioremediation of the Upper Aquifer.

摘要

UWRL investigators, led by Ronald C. Sims, continue to evaluate the Champion International Superfund Site in Libby, MT. They are investigating the effectiveness of the following biological treatments of contaminated soil and groundwater: (1) surface soil bioremediation in a lined, prepared-bed land and treatment unit; (2) oil-water separation of extracted groundwater after aqueous phase treatment in above-ground, fixed-film bioreactors; and (3) in-situ bioremediation of an upper aquifer. The design, operational, monitoring, and performance activities of each treatment are being considered. The study is part of the US EPA Bioremediation Field Initiative, and began in July 1991.
