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)
