Contaminated Site Management and Remediation Investigations
University of Virginia and Princeton University scientists collecting water from lysimeters at the site (circa 1992). The sprinkler was used to simulate rainfall so an estimate of the amount of trichloroethylene (TCE) being redissolved by percolating rainfall could be made -- from the Picatinny Arsenal Site
The Toxics Program conducts intensive field investigations to study common classes of subsurface
point-source contamination. (more information)
Contamination in Fractured-Rock Aquifers
Petroleum Related Contamination (including crude oil,
gasoline and produced water)
Chlorinated Solvents Contamination
Contamination from Sources with Mixed Wastes (including landfills
and wastewater discharge)
