Site Background
In March 2010, the Missouri Department of Natural Resources (MDNR) Public Drinking Water Branch (PDWB) found trichloroethylene (TCE) in two non-community wells and an irrigation well on the western edge of Rogersville, Missouri. MDNR’s Superfund Section initiated a combined Preliminary Assessment/Site Investigation (PA/SI) integrated Removal Site Evaluation (RSE) on March 24, 2010. Initial sampling events found 13 of the 100 wells sampled had detectable concentrations of TCE. MDNR requested that the EPA provide an alternate water supply to households drinking contaminated water.
Five drinking water wells within that sampling group had TCE concentrations above the maximum contaminant level (MCL) of 5 parts per billion (ppb). Of these 5 residences, four have been provided whole-house granulated activated carbon filtration systems and one has had a new drinking water well installed.
Since the installation of the original 5 alternative water supplies in August of 2010, none of the other 501 wells sampled in the area have met the removal criteria.
The source of the TCE release is unknown at this time but, is still under investigation.
The site is on the National Priorities List and sampling is taking place under the EPA Superfund Remedial Program. The EPA Superfund Remedial Program continues to sample wells and investigate the release of TCE.
This site has been placed on National Priorities List (NPL) and is being transitioned to Devin Pollock Remedial Project Manger (RPM) for the EPA who can be contacted at (913) 551-7275.
