DELINEATION OF A HYDROCARBON (WEATHERED GASOLINE) PLUME IN SHALLOW DEPOSITS AT THE U.S. NAVAL WEAPONS STATION, SEAL BEACH, CALIFORNIA; WATER RESOURCES INVESTIGATION

Gasoline from a leaking underground storage tank at the U.S. Naval Weapons Station in Seal Beach, California, was found to have spread almost radially through the shallow subsoil a distance of 150 to 300 feet from the source. Deposits in an area of 160,000 square feet in a zone 1 to 2 feet thick above the shallow water table are contaminated. Seasonal and tidal fluctuations in ground water have spread the gasoline vertically in the subsoil and thereby reduced gasoline concentration below residual saturation in nearly all the contaminated area. Total quantity of gasoline contained in gasoline-unsaturated subsoil is estimated to be 5,800 gallons. The quantity present in gasoline-saturated subsoils was not determined.
