Significant Drinking Water Threat Policy Applicability Map

TCE and chlorides are contaminants that can spread through groundwater flow. It already resides within the boundaries of the Protected Drinking water source in West Galt.  The West Galt watershed is listed as being at a “high risk for contamination” by the GRCA.

Groundwater contamination by TCE has become an important environmental concern for human exposure.

Another significant source of vapor exposure is by showering.  A daily task that could threaten your health. TCE readily volatilizes out of hot water and into the air. Long, hot showers would then volatilize more TCE into the air. In a home closed tightly to conserve the cost of heating and cooling, these vapors would then recirculate.

In 2005 it was announced by the United States Environmental Protection Agency that the agency had completed its Final Health Assessment for Trichloroethylene and released a list of new TCE toxicity values. The results of the study have formally characterized the chemical as a human carcinogen and a non-carcinogenic health hazard. A 2011 toxicological review performed by the EPA continues to list trichloroethylene as a known carcinogen.
