Is Perchloroethylene bad for the environment?
PCE can leach rapidly through sandy soil and therefore may reach groundwater. PCE is reported to be the chemical most widely found in groundwater contamination at Superfund Sites. When PCE is released in water, the primary loss is by evaporation. Chemical and biological degradation are expected to be very slow.
