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

A vapor-flux measuring device (black box) and well head (white circle).
This vapor-flux measuring device was developed by Jim Smith of the University of Virginia (formally of the USGS). Trichloroethylene (TCE) volatilizing upward through the unsaturated zone under the dome was captured on two adsorbent traps. The device was used to estimate the importance of TCE volatilization as a loss mechanism from the plume (circa 1993).

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.
