Perchloroethylene (PCE) Releases in Nevada

PCE or Perchloroethylene (also known as Tetrachloroethylene, Tetrachloroethene, PERC or PCE) is a synthetic chemical that is widely used for dry cleaning of fabrics and for metal-degreasing operations.

PCE has relatively low solubility in water and has medium-to-high mobility in soil. It tends to volatilize (evaporate) from surface environments; however, it may persist in subsurface soil and groundwater for months or years, depending on subsurface conditions.

Sites contaminated with PCE are found in virtually every major city and state within the U.S. The Las Vegas Valley and the Reno metro area are no different. Fortunately, the geology and hydrology in the Las Vegas Valley largely restrict PCE contamination to the shallow groundwater, which is not used as a water supply source due to its naturally poor quality (high salt content).
