Section A - Gasoline in Ground Water in Galloway Township, New Jersey

Section A addresses the biodegradation of gasoline in ground water that resulted from a leaking underground storage tank in Galloway Township, New Jersey. The papers describe methods to determine in situ biodegradation rates of gasoline on the water table, the geochemistry of gasoline constituents dissolved in ground water, and air-flow modeling of gas transport in the unsaturated zone.
