Field investigation of natural attenuation of chlorinated solvents--Picatinny Arsenal, New Jersey

A core is being extruded from a core barrel into a glove box. The outside layer of the core was pared, and the core was collected in a sterile jar. The sediment samples were used for soil microcosms studies of the biodegradation of contaminants (circa 1989).

Trichloroethylene (TCE), which is a common cleaning solvent and degreaser, has contaminated a sand and gravel aquifer near Picatinny, New Jersey. Investigations have focused on measuring natural processes that are removing TCE from ground water (such as degradation by microbes and loss as vapors to the atmosphere), identifying causes for the persistence of TCE in the aquifer, and field testing new remediation technologies.
