Gasoline Release

A pipeline company discovered a gasoline release at its Glenpool,OK storage terminal near Tulsa. The initial site investigation confirmed that subsurface soil and groundwater near the point of release were affected by petroleum products. A series of geoprobe borings located and delineated the gasoline plume. Free product ranging in thickness from a sheen on the water to over two inches was recorded in twenty-one of the borings. Based on physical site factors, our experts recommended Mobile Dual Phase Extraction (MDPE) technology in order to remove the free product and achieve the required cleanup levels at the site. The MDPE process was successful in extracting, under high vacuum pressures, hydrocarbons at the water interface as well as the unsaturated zone. Hydrocarbon contaminants in ground water were reduced to risk-based levels that allowed the Oklahoma Corporation Commission to close this case.
