Petroleum Related Contamination

Subsurface spills of petroleum compounds (crude oil, gasoline, and gasoline additives) may be the most frequently cited cause of ground-water contamination. USGS scientists and their partners are developing information and tools essential for effective remediation and long-term management of fuel spills. A major theme of this research is the effectiveness and practical limitations of Natural Attenuation for treatment of sites with petroleum related contamination. Research has been conducted at 4 research sites:

Crude Oil Contamination in a Shallow Outwash Aquifer -- Bemidji, Minnesota

Oxygenated Gasoline -- Laurel Bay, South Carolina

Produced Water -- Osage-Skiatook Petroleum Environmental Research Project, Oklahoma

Gasoline -- Galloway Township, New Jersey [Completed]
