tce in groundwater

Trichloroethylene (TCE) Fact Sheet P

TCE released onto soil can enter groundwater Therefore people who drink water from wells located near TCE disposal sites may be exposed The amount of TCE in commercial products is much more concentrated than in contaminated drinking water Plants grown on contaminated soil do not accumulate TCE

Trichloroethene Contamination of Ground Water

Concentrations of TCE from the passive-diffusion samplers were generally similar to concentrations found in samples collected in the same wells using conventional pumping methods In contrast to conventional pumping methods the collection of ground-water samples using the passive-diffusion samples did not generate waste purge water that would require hazardous-waste disposal

AVX Corp TCE Groundwater Contamination Class Action

A class action lawsuit has been filed against the electronics manufacturer claiming groundwater contamination The lawsuit claims AVX Corp knew about trichloroethylene or TCE contamination at its site since at least 1981 although the manufacturer did not tell the South Carolina Department of Health and Environmental Control (DHEC) about the problem until 1995 In 2006 the DHEC first
