Contaminated Site Management and Remediation Investigations
A technician is pumping water from a multi-level well during an investigation of the natural attenuation of a chlorinated solvent plume under a fire training pit. Tubing from the well leads to an in-line multi-parameter probe that records pH, dissolved oxygen, Eh, and temperature -- from the Wurtsmith Site
The Toxics Program conducts intensive field investigations to study common classes of subsurface
point-source contamination. (more information)
