Contaminated Site Management and Remediation Investigations
A view of a mudstone of the Lockatong Formation, showing bedding (dipping gently to the left of the picture), bedding-plane parting fractures, and strata bound vertical jointing (rock face just to left of the hammer). Fractures such as these control the transport of trichloroethylene (TCE) at the site -- 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)
