Davis Timber Company
The 30-acre Davis Timber Company Superfund site is outside of Hattiesburg, Mississippi. From 1972 until the late 1980s, Davis Timber Company ran a wood-preserving facility at the site. Operators put contaminated wastewater in an on-site storage pond, contaminating soil and sediment. EPA added the site to the National Priorities List (NPL) in 2000. EPA led cleanup activities at the site between 2011 and 2012. Cleanup included digging up contaminated soil and sediment, placing waste under a 3-acre capped area, and controlling surface water flow and erosion. Institutional controls are in place to limit future land uses. After cleanup was complete, EPA took the site off the NPL in 2018. After a reuse assessment, the site owner donated a 3-acre area for use as a community center and polling location. This building is located off site. The Hub City Humane Society operates an animal shelter and the Fields of Barktopia Dog Park on site. Other site uses include creeks and wetlands, parking, connections to the 41-mile Longleaf Trace recreation trail, a community center and restored habitat for pollinators. In 2015, EPA Region 4 recognized the site property owners and the Hub City Humane Society’s leadership with its Excellence in Site Reuse award.

Flowood Site
The 225-acre Flowood Superfund site is in Flowood, Mississippi. The site is in the wetlands and lowlands area of the Pearl River floodplain. Starting in the 1940s, two manufacturing facilities operated on- site. For over 20 years, operators sent polluted wastewater into a nearby canal without a state permit. The state asked EPA to study the area. EPA found high levels of lead in canal water, sludge and soils. EPA added the site to the National Priorities List (NPL) in 1984. EPA worked with the state and facility owners to remove contaminated soil and monitor the groundwater. The cleanup and improved disposal practices protected area residents and nearby ecological resources. They also enabled industrial facilities to remain active on- site, retaining jobs and income in the community. After cleanup, EPA took the site off the NPL in 1996. Several businesses, including a flea market and a packaging and supply company, are in the former Rival Manufacturing Corporation building on site.

As of December 2023, EPA had data on 8 on-site businesses. These businesses employed 42 people and generated an estimated $37,112,690 in annual sales revenue. For additional information click here.

Mississippi Phosphates Corporation
The Mississippi Phosphates Corporation (MPC) Superfund site is located in Pascagoula, Mississippi. The Mississippi Phosphates Corporation ran a fertilizer manufacturing facility at the site from the late 1950s until it declared bankruptcy in 2014. MPC created a Liquidation Trust to market and sell facility assets and an Environmental Trust to manage the facilities' liabilities. The Environmental Trust managed groundwater treatment and site stability activities. In 2017, the state of Mississippi added funding from the state’s Pollution Emergency Fund to the Environmental Trust. Once the funds were exhausted in 2017, the Environmental Trust became insolvent. EPA added the site to the National Priorities List (NPL) in 2018. EPA assumed control of funding wastewater treatment and site stability operations. In 2018, EPA approved a three-phase closure plan to accelerate cleanup. The plan includes wastewater treatment and discharge and engineering of a geosynthetic turf cover system. Closure work at the site is ongoing. EPA treats wastewater at a rate of about 2 to 4 million gallons per day. In 2023, the site was added to those selected by EPA to receive cleanup funding under the Bipartisan Infrastructure Law (BIL). With this funding, EPA is already initiating work on backlogged remedial construction projects and accelerating cleanups at NPL sites. The site’s Liquidation Trust has been actively marketing the property to buyers interested in purchasing and redeveloping the facility. EPA will conduct studies and follow-on cleanup work as needed, after parties confirm the scope of reuse plans. EPA continues to work on cleanup plans for other actions needed at the site. Current site uses include a credit union and an industrial district that hosts a natural gas processing plant and a general contractor.

Rockwell International Wheel & Trim
The 40-acre Rockwell International Wheel & Trim Superfund site is in Grenada, Mississippi. From 1966 to the early 2000s, companies ran wheel-cover manufacturing and chrome plating facilities on site. Operations contaminated soil, groundwater and surface water with volatile organic compounds (VOCs) trichloroethylene (TCE), toluene and chromium. VOCs were migrating from under the concrete floor into the manufacturing building via a process known as vapor intrusion. In December 2017, the potentially responsible party restarted a sub-slab depressurization system (SSDS) to prevent contaminated vapors entering the facility. This system has decreased contaminant concentrations in facility air to below health-based risk levels. A Removal Action was approved in 2022 and the system is currently being installed to address groundwater contamination on the facility property. EPA added the site to the National Priorities List (NPL) in 2018. Site investigations, monitoring and cleanup are ongoing. The metal-stamping operation, now owned by Ice Industries Grenada, remains active on site.

Sonford Products
The 6-acre Sonford Products Superfund site is in Flowood, Mississippi. From 1972 to 1985, Sonford International and Sonford Products operated two separate chemical manufacturing plants at the site. In 1985, a 2,000-gallon spill of pentachlorophenol (PCP) occurred at the site. Manufacturing operations ended. Plant operations contaminated soil, sediment, surface water and groundwater. In 1985, EPA dug up contaminated soil and oil, treated solution and wastewater from the site, and disposed of it all at an off-site facility. The site was re-evaluated in 2004 and was added to the National Priorities List (NPL) in 2007. From 2014 – 2020, groundwater extraction wells were installed and used to remove free-product non aqueous phase liquid (NAPL) contamination from groundwater at the site. Groundwater monitoring is ongoing. In 2021, a pilot study was conducted at the site to assess the effectiveness of a soil treatment technology for removing PCP from the subsurface soils. EPA and the Mississippi Department of Environmental Quality continue to work together on cleanup efforts. The site includes the Sonford Products parcel, an undeveloped parcel referred to as the Wixson parcel to the south, and the Payne Drive neighborhood to the west. Dense woods cover the Wixson parcel. The Payne Drive neighborhood includes 22 permanent and mobile homes. A concrete septic tank manufacturing facility is currently operating on the Sonford Products parcel. It uses and stores septic tanks and heavy machinery. In December 2021, the site was among those selected by EPA to receive cleanup funding under the Bipartisan Infrastructure Law (BIL). With this funding, EPA is already initiating work on backlogged remedial construction projects and accelerating cleanups at NPL sites. At the Sonford Products site, BIL funding is being used to implement the full-scale treatment of subsurface soil contamination beginning in September 2023.

Southeastern Wood Preserving
The Southeastern Wood Preserving Superfund site is in Canton, Mississippi. Several companies treated wood on site from 1928 to 1979. They used coal tar, creosote and pentachlorophenol as preservatives. Operators built three unlined wastewater holding ponds for disposal of wood-preserving treatment sludges and process wastewater. Before 1977, the facility reportedly discharged 50,000 gallons of wastewater directly into Batchelor Creek. In 1985, EPA started removing contaminated soils and put in a slurry wall to prevent creosote flowing into Batchelor Creek. In 1989, EPA led a creek widening and deepening effort to better stabilize its banks. EPA added the site to the National Priorities List (NPL) in 2012. Long-term cleanup plans call for a longer and deeper barrier wall for the creek. They also call for excavating shallow contaminated soils and placing them inside the barrier wall, capping the barrier wall, and adding stormwater controls. EPA approved the cleanup plans in 2018. In December 2021, the site was among those selected by EPA to receive cleanup funding under the Bipartisan Infrastructure Law (BIL). With this funding, EPA is already initiating work on backlogged remedial construction projects and accelerating cleanups at NPL sites. A logging yard is active on site.
