Casper PCE Plumes Orphan Site
 

Orphan Site Description: 

The Casper Perchloroethylene (PCE) Plumes orphan site is approximately 150 acres in an area that is bound to the north by the North Platte River, to the south by the Yellowstone Highway, to the west by Elm Street and to the east by Washington Street.  The area is comprised of residential, commercial and industrial neighborhoods.  Environmental testing in the late 1980s and early 1990s revealed the presence of PCE in groundwater at three locations in downtown Casper and two locations in North Casper and in the indoor air of some homes.

 Casper PCE Plumes Orphan Site is one of the high priority orphan sites on the Wyoming Department of Environmental Quality (DEQ) list.  New regulatory standards for PCE and updated technology for testing vapor intrusion, along with newly available funding for the DEQ, is the rationale for this additional investigation into the Casper PCE Plumes Orphan Site.
