244.5 - Devil’s Swamp Lake Superfund Site
Devil’s Swamp is located on a point of land surrounded by, and regularly flooded by, the Mississippi River and is about ten miles north of the City of Baton Rouge. Devil’s Swamp is a wetland, flood plain and lake covering approximately 9 square miles of land along the Mississippi River. The swamp to the north of the lake is characterized by numerous small open ponds and water tupelo trees. Industrial facilities have discharged to the swamp since the 1960's and the 1970's.
Sampling conducted by the State and the EPA show concentrations of PCBs congeners as the contaminant of concern. Congeners are well-defined chemical compounds in the PCB category.
The site was proposed to the NPL list in the Federal Register on March 8, 2004. The EPA completed evaluation and negotiations with some Potential Responsible Parties (PRPs) and issued an Unilateral Administrative Order (UAO) to PRPs to conduct a Remedial Investigation/Feasibility Study (RI/FS) on December 3, 2009.
