The Picayune Wood Treating site is located in Picayune, Mississippi. It includes the area where various timber and lumber-related operations took place from the early 1900s to 1999. EPA placed the site on the National Priorities List (NPL) in 2004 because of contaminated groundwater, soil and sediment resulting from facility operations. EPA and the Mississippi Department of Environmental Quality (MDEQ) have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination.

EPA has dug up contaminated soil identified on residential properties near the site and placed the soil in a fenced area on-site. Both residents and businesses use the public water system for drinking water, and site contamination has not affected the system. In September 2010, EPA approved funding to carry out the approved cleanup plan for the site. By conducting groundwater monitoring, EPA and MDEQ continue to protect people and the environment from site contamination. Excavation of soil and sediment finished in August 2013. Two containment cells were created on site to hold contaminated soil. Groundwater monitoring is underway.
