TCE Dumped by W.R. Grace Contaminated Wells G and H

Until the mid-1970's, the Cryovac plant of W.R. Grace, a global producer of chemical, construction, and container products, dumped varying amounts of toxic chemicals, including the industrial solvent trichloroethylene (TCE), on its property in Woburn. These chemicals, often referred to by the general term volatile organic compounds (VOC), seeped into the groundwater beneath Grace's property and migrated through the underlying aquifer in a southwesterly direction.

This chart shows the groundwater flow from the W.R. Grace plant (marked "WRG" in the top right corner) to Wells G and H, part of the Woburn municipal water supply.
