Superfund Site Groundwater AssessmentGeolocation: 44.9958, -92.8794

Terracon was selected to provide consulting services on a groundwater plume constituting the Baytown Groundwater Contamination Site Superfund site. The site contains a groundwater plume contaminated with trichloroethylene (TCE). The plume was present east of the town of Lake Elmo, Minn., and extended eastward beyond the Lake Elmo Airport towards the St. Croix River.

The Environmental Protection Agency and the Minnesota Pollution Control Agency jointly oversee the project.
