Bioremediation techniques on crude oil contaminated soils in ohio. final report includes the quarterly report that ended 12/31/1996

摘要

The purpose of this study is to define the optimum limits of chemical and physical conditions that reduce soil salinity and maximize indigenous aerobic microbiological populations in the bioremediation of oil field waste solids. Specifically, the study centers around treatment of surface contained oily waste having low density and limited solubility in water. Successful remediation is defined by total petroleum hydrocarbon (TPH) reduction to 1% and no hydrocarbon or salinity impact on ground water resources. The Department of Energy, the US Environmental Protection Agency and the Interstate Oil and Gas Compact Commission have encouraged oil and gas producing states to identify and develop improved methods such as this to reduce, recycle or treat solid waste generated with the exploration and development of domestic petroleum resources (IOGCC, 1995). With encouragement and funding assistance through the Department of Energy, Ohio is developing these bioremediation practices to protect soil and water resources. Ohio produced 8,300,000 barrels of crude oil in 1996 from wells operated by 4310 registered owners (ODNR, 1996). Good well site housekeeping can minimize spills, however accidental spills inevitably occur with oil production of this magnitude. Development of sound environmental and economical clean-up procedures is essential.
