Contaminated Site Management and Remediation Investigations
Drilling operations at the NAWC site (circa 2005). Samples of rock core were collected and were analyzed for concentrations of volatile organic compounds (VOCs) at about 50 various depths, providing a direct measure of the contaminant concentrations in the rock matrix -- from the Naval Air Warfare Center (NAWC) Research 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)
