Annapolis Lead Mine

The Annapolis Lead Mine Superfund site is located in Iron County, Missouri. The 200-acre site includes historic mining areas, Sutton Branch Creek and its floodplain, and the town of Annapolis. Massive piles of mining waste left on site eroded over time, resulting in lead contamination of soils, sediments and nearby bodies of water. EPA added the site to the National Priorities List (NPL) in 2004. EPA worked with the Missouri Department of Natural Resources (MDNR) and the U.S. Fish and Wildlife Service to develop a cleanup plan. The plan addressed contaminated sediments in the Sutton Branch Creek floodplain and contaminated soils in nearby residential yards. Workers dug up and combined contaminated materials, capped them, and planted the area with warm and cool season grasses. EPA and MDNR also planted over 1,000 trees, revegetating parts of the site. Cleanup activities also stabilized parts of the creek. In the town of Annapolis, EPA and MDNR tested soils and treated contamination. Studies focused on areas attractive to children, such as residential yards, school yards and church yards. Cleanup construction finished in 2007. EPA deleted the site from the NPL in 2020. MDNR continues to monitor water quality at the site and conducts regular maintenance activities to ensure the remedy remains protective of human health and the environment. Hay production takes place on a small part of the Sutton Branch Creek floodplain.

Armour Road 

The Armour Road Superfund site is in North Kansas City, Missouri. From the 1920s to 1986, an herbicide mixing and packaging facility operated on the 1.8-acre site property at 2251 Armour Road. The first operator, Reade Manufacturing, owned and operated at the facility from the 1920s until 1963. In 1963, Reade Manufacturing leased the property to U.S. Borax, which continued herbicide mixing operations until 1968. Horne and Boatright Company (HABCO) bought and operated the facility until it shut down in 1986. Herbicide transport and spraying operations resulted in arsenic contamination in soil and groundwater at the facility. In 1989, an environmental site assessment for a potential purchaser of the property identified high levels of arsenic and other herbicide-related contaminants in the soil and groundwater at the site. The Missouri Department of Natural Resources (MDNR) entered into a consent decree with the owners of the property in 1993 to conduct preliminary soil sampling. MDNR confirmed the high arsenic levels and reported the site to EPA. In 1996, EPA led a time-critical removal action. EPA demolished buildings and covered soil with geofabric and crushed rock to prevent contaminated dust and dirt from moving off site. EPA added the site to the National Priorities List (NPL) in 1999. Under the oversight of EPA, U.S. Borax and its successor, Rio Tinto Mining Company, have completed long-term cleanup activities included decontaminating and demolishing remaining site buildings, relocating utilities, removing and treating arsenic-contaminated soils, and backfilling site areas with clean soil. A medical center and restaurant are now on site. The site’s new roadway is also a vital link to the nearby One North Redevelopment Area, a high-density, mixed-use hub that will include office space, stores, hospitality centers and residential areas. The urban center incorporates areas to the west of the site property that were formerly commercial and light industrial. In September 2019, EPA Region 7 gave the city of North Kansas City and Rio Tinto Mining Company its Leading Environmentalism and Forwarding Sustainability (L.E.A.F.S.) Award in recognition of responsible reuse through innovative thinking, sustainable practices and environmental stewardship at the site.

Big River Mine Tailings/St. Joe Minerals Corp.

The Big River Mine Tailing/St. Joe Minerals Corps. Superfund site is in Desloge, Missouri. The site is part of a former mining region about 70 miles south of St. Louis, often referred to as the "Old Lead Belt." From 1742 to 1972, mining operations resulted in enormous piles of mine waste tailings and chat on site. The site consists of eight large areas of mine waste. It spans about 110 square miles. For example, St. Joe Minerals Corporation’s operations disposed of mine tailings across a 600-acre rural area bordered on three sides by the Big River. In 1977, heavy rains caused about 50,000 cubic yards of the Big River Mine Tailings Pile to slump into the Big River, contaminating surface water and soil with heavy metals. Since mining activities ended, the Big River 100-year floodplain is mainly used for agricultural crops and pasture lands. Area residents and businesses used the mine waste as fill for construction projects and as agricultural amendments. Contaminants from the waste seeped into the Big River. After investigations, EPA added the site to the National Priorities List (NPL) in 1992. The remedy includes mine waste removal and stabilization as well as treatment of dissolved zinc in groundwater seeps. Current land uses across this large site include residential, commercial, industrial, recreational, public services, agricultural and ecological areas. EPA and potentially responsible parties test residential properties, schools, day cares and parks for heavy metals. EPA and potentially responsible parties replace contaminated soil as needed. Many commercial and industrial businesses and organizations are on site. They range from insurance agencies, car dealerships and restaurants to automotive repair shops and a variety of manufacturing operations. People use the Big River for recreation, fishing, canoeing and watering of livestock. The state of Missouri advises people not to eat fish they catch from the Big River downstream of contaminated areas. St. Joe State Park, or the Federal Mine Tailings site, offers recreation opportunities and ecological resources. Museums highlighting Missouri mining history and mineral resources are located on the sub-site as well. Maturing second-growth forests with native oak and hickory, as well as native grasslands, support native wildlife. People visit the park to hike, camp, ride off-road vehicles and view wildlife. Several city parks, playgrounds, athletic fields and a drag-racing strip offer more recreation resources. Mark Twain National Forest, managed by the U.S. Forest Service, is partially on site. Public service uses in the site area include libraries, emergency service and fire services facilities, law enforcement facilities, postal services, and utility services. The St. Francois County Environmental Corporation operates a transfer station on the Desloge Mine Tailings Pile. A healthcare facility and a mining museum are also located on former source areas. In 2019, EPA’s Superfund Redevelopment Program (SRP) began supporting a regional seed project to develop a reuse assessment at the site. The 2019 assessment identifies community redevelopment priorities across four cities – Park Hills, Bonne Terre, Leadwood and Desloge – in St. Francois County. Development of a solar reuse assessment for the site was completed in June 2021.

Ellisville Site

The Ellisville Superfund site is in St. Louis County, Missouri. The site includes three separate properties, called operable units (OUs). The 85-acre Rosalie property is OU1. A sewer worker found buried drums on the property in 1980. Site investigations in the 1980s found the buried drums had contaminated soil at OU1. The 11.6-acre Bliss property is OU2. The Bliss Waste Oil Company operated at OU2 during the 1960s and 1970s. The company disposed of wastes on site by dumping and burying drums. The 8-acre Callahan property is OU3. In 1980, investigations found buried drums at OU3. EPA added the site to the National Priorities List (NPL) in 1983. To clean up OU1 and OU3, EPA removed contaminated soils and drums, backfilled with clean soil, and reseeded the area. Cleanup for OU2 included removing contaminated soil and either incinerating it or transporting it to a permitted landfill. Groundwater investigations by EPA and the Missouri Department of Natural Resources are ongoing. A residential housing subdivision is currently located on OU1. A developer purchased the adjacent property for future residential use. EPA deleted OU3 from the NPL in 2017.

Fulbright Landfill

The Fulbright Landfill Superfund site is in Springfield, Missouri. The site consists of two closed landfills – the 98-acre Fulbright Landfill and the 114-acre Sac River Landfill. From 1962 to 1974, the landfills accepted industrial and domestic wastes that contaminated soil and groundwater. In 1983, EPA added the site to the National Priorities List (NPL). EPA and the parties responsible for the contamination, including the city of Springfield (City), cleaned up known areas of contamination at both landfills. These groups completed cleanup in 1992. Groundwater monitoring is ongoing. The site’s location near the Little Sac River is ideal for recreational use. The City expressed interest in expanding nearby trails onto cleaned-up areas of the site. EPA’s Superfund Redevelopment Program (SRP) supported a reuse planning process to identify potential future uses that could be compatible with the site’s remedy. Stakeholders met in 2004 and 2005 to explore reuse options as well as innovative techniques to protect the site’s remedy. A police department firing range continues to operate on site. In 2020, a segment of the Fulbright Spring Greenway Trail opened on site. It connects to several local parks, neighborhoods and an elementary school. People use it for walking, biking and running. More trail work is underway.

Madison County Mines 

The 511-square-mile Madison County Mines Superfund site includes all of Madison County and part of the historical “Mine La Motte Tract” that extends into St. Francois County, Missouri. Mining operations began in the area in the early 1700s. They ended in the mid-1900s. Mine operations left behind 13 major tailings and chat deposit areas. Contaminated soil, tailings and chat were used in residential areas for fill, foundation bases, driveway aggregate and topsoil. Contaminated materials were also used as aggregate for road construction and as traction on public roadways during winter weather. EPA added the site to the National Priorities List (NPL) in 2003. Cleanup includes removing contaminated soil from homes and areas visited by children, such as daycare facilities, parks and greenways and replacing it with clean soil. Mine waste locations are being addressed in stages, as cleanup plans are finalized. The primary cleanup actions are grading to prevent erosion and putting caps in place. A Health Education Program and a Voluntary Institutional Controls Program (VICP) are in place through cooperative agreements with the Missouri Department of Health and Senior Services. The Madison County Health Department manages the programs. They raise public awareness of the presence of lead and its effects on human health and the environment. The VICP monitors ground disturbance activities across Madison County. It also provides sampling, outreach and assistance to citizens, public utilities and contractors. The U.S. Forest Service manages part of the Mark Twain National Forest within the site for a variety of recreational and other uses, including the Silver Mines Recreation Area. The federal recreation area supports hiking, camping and water access for fishing and kayaking. Other continued uses at the site include residential, recreational, commercial, industrial, ecological and agricultural areas. Missouri Cobalt, LLC is reprocessing legacy mine wastes at the former Madison Mine to recover valuable metals, and is evaluating the potential to revitalize underground mining of cobalt and other critical metals. EPA partnered with the Madison County Health Department, area organizations and a remedial site contractor to host the Madison County Mines Superfund Job Training Initiative (SuperJTI) at the site from December 2017 to March 2018. This initiative provided 24 local job seekers with new skills, certifications and hands-on training for construction and cleanup.

Minker/Stout/Romaine Creek

The Minker/Stout/Romaine Creek Superfund site includes about 10 acres of separate properties near Imperial, Missouri. In the early 1970s, site operators sprayed dioxin-contaminated oil on the Bubbling Springs Ranch horse arena to control dust. This resulted in the death of several horses. Dioxin-contaminated soil removed from the horse arena ended up as fill material in residential areas. These areas included the Minker, Stout, Cashel and Sullins residences. Much of the fill from the Minker residence eroded into Romaine Creek. In 1983, EPA detected dioxin in the soil on site and in Romaine Creek sediments. EPA added the site to the National Priorities List (NPL) in 1983. EPA also permanently relocated 11 families affected by the contamination. Between 1985 and 1989, EPA removed about 28,420 tons of soil at the Minker area, the Sullins and Cashel residences, Romaine Creek and the Stout area. EPA sent the contaminated soil off site for incineration in 1996 and 1997. Contamination in three inaccessible portions of Romaine Creek below the residential area were capped, leaving some waste in-place at depth in the drainage. EPA completed cleanup in 1997. The state temporarily relocated two other families during cleanup of the Minker area. The site remains in continued residential use.

Newton County Mine Tailings

The 300-acre Newton County Mine Tailings Superfund site is in Newton County, Missouri. Extensive mining in the area between 1850 and 1970 resulted in underground mine openings with exposed lead, cadmium and zinc ores. Waste from mining activities contaminated surface soil, sediments, surface water and groundwater with heavy metals. EPA added the site to the National Priorities List (NPL) in 2003. Cleanup activities include removal and disposal of contaminated soils and sediments, capping of disposal areas, revegetation of the excavated and capped areas, and monitoring. Institutional controls will restrict the use of the disposal areas. Removal of contaminated residential yard soils and temporary replacement of residential water supplies has restarted at the site. There is ongoing cleanup of heavy metal-contaminated wastes, soil and sediment. EPA will continue to work on road repair and revegetation. A city park has reopened on site. The city put in new sand courts for volleyball. The park also has a playground, picnic pavilions, open space and an athletic field for other sports such as soccer. Ongoing remediation of mine waste and contaminated soils has returned over 100 acres to beneficial use, including residential and agricultural uses.

Oronogo-Duenweg Mining Belt

The 250-square-mile Oronogo-Duenweg Mining Belt Superfund site is in Joplin, Missouri. Mining, milling, and smelting of lead and zinc ores at the site began in the 1850s. These operations continued in some site areas until the 1970s. Smelting operations dispersed airborne contaminants, contaminating site groundwater, surface water and soil with metals, including lead. EPA added the site to the National Priorities List (NPL) in 1990. EPA led a time-critical removal action to address high blood lead levels in local children. EPA cleaned up about 2,500 residential properties and agricultural lands in surrounding communities. The city of Joplin cleaned up lead-contaminated soil at 443 more homes as part of the recovery from a tornado in 2011. Other work included connecting 350 homes to public water supplies, digging up mine waste from 4,500 acres of contaminated land, and constructing wetlands. Further cleanup will address contaminated sediments in the Spring River. Through the efforts of EPA, the state of Missouri and the community, the site is in productive reuse. Residential and agricultural land uses are ongoing. After signing a Prospective Purchaser Agreement with EPA, a scrap metal recycler bought and cleaned up 40 acres of the site before building its facility. The Missouri Highway and Transportation Department built a Route 249 highway bypass across part of the site. The project reused mine wastes as fill material and developed a guideline for the development of areas containing these wastes. The Route 249 Development Plan contains details on zoning, land use and institutional controls to facilitate sustainable development while protecting human health. In 2021, a local utility provider, Liberty Utilities – Empire District completed a 12-acre pilot solar farm on part of a mine waste repository. The utility plans to expand the solar farm to the entire 60-acre repository if the pilot project is a success.  The Joplin Missouri is experiencing very strong housing construction and numerous areas of remediated mine lands are being developed into residential housing. Additional reuse planning is underway. Over 4,000 acres of cleaned-up land are ready for redevelopment.

Syntex Facility

The Syntex Facility Superfund site is in an agricultural area in Verona, Missouri. Initial use of the 180-acre area along the Spring River was for agricultural and recreational purposes. Hoffman-Taff began manufacturing chemicals on site in the 1960s. Hoffman-Taff produced 2,4,5-trichlorophenoxy-acetic acid for the U.S. Department of Defense as part of the production of Agent Orange. Hoffman-Taff leased part of the facility to Northeaster Pharmaceutical and Chemical Company (NEPACCO) for the production of hexachlorophene, a chemical antiseptic. Syntex Agribusiness (Syntex) bought the facility in 1969, with NEPACCO continuing to operate until 1972. Dioxin was an unwanted intermediate byproduct of chemical production and purification of hexachlorophene. Waste disposal in several areas at the facility contaminated soil and groundwater. Fish downstream in the Spring River also showed signs of contamination. State and federal agencies began investigating the facility for pollution releases in 1980. EPA added the Syntex facility to the National Priorities List (NPL) in 1983. EPA removed and treated contaminated soil using thermal techniques, and capped and revegetated removal areas. The shallow aquifer in the area is used by rural households for domestic purposes and some agriculture. Water utilities and large-scale agricultural operations use the deep aquifer. A chemical manufacturing facility currently makes nutritional supplements on a 100-acre area of the site.

Times Beach

The 1-square-mile Times Beach Superfund site is located 20 miles southwest of St. Louis, Missouri. The site is a formerly incorporated city that sprayed its roads with waste oil to control dust in the early 1970s. During a 1982 investigation, EPA discovered that the city used dioxin-contaminated oil. During the same period, the nearby Meramec River flooded the city and residents had to evacuate their homes. Afterward, the Centers for Disease Control and Prevention recommended the permanent relocation of the evacuated residents. EPA added the site to the National Priorities List (NPL) in 1983. EPA also transferred funds to the Federal Emergency Management Agency (FEMA) for the permanent relocation of residents and businesses in 1983. All residents successfully relocated by the end of 1986. The state of Missouri then took ownership of the site. Cleanup activities finished in 1997. In 1999, a state park opened at the restored site. EPA took the site off the NPL in 2001. The Route 66 State Park includes a portion of old Route 66, including the historic bridge across the Meramec River. The park provides more than 7 miles of trails for hiking, biking and equestrian use. Visitors can see a range of wildlife, including turkeys, geese, deer and more than 40 species of birds. Other park facilities include picnic areas and a boat ramp that provides access to the Meramec River. In 2012, EPA completed a reassessment of the park to determine, in part, if any residual dioxin contamination remained above the recently revised non-cancer reference dose. The reassessment concluded that current use of the Route 66 State Park does not pose risks to public visitors or park workers.

Valley Park TCE

The Valley Park TCE Superfund site is in Valley Park, Missouri. Wainwright Industries and Valley Technologies used the area for metal processing. Wainwright Industries stopped operating on site in 1979. Several other nonmanufacturing businesses then operated at the former Wainwright Industries property. Valley Technologies continues to operate on site. To manage the cleanup, EPA divided the site into four operable units (OUs): OU1 - Wainwright Remedial Soil, OU2 - Valley Technologies Soil, OU3 - Wainwright Remedial Groundwater, and OU4 - Valley Technologies Groundwater and Area Wide Plume. OU1 addresses the soil contamination in an area within and next to the property formerly owned by Wainwright Industries. OU2 addresses the soil contamination within and next to the property currently owned by Valley Technologies. OU3 addresses groundwater contamination beneath OU1. OU4 addresses the groundwater contamination beneath OU2 and the portions of the commingled, contaminated groundwater plume not addressed by OU3. OU1 and OU3 make up Wainwright Operable Unit (WOU). The selected remedy for WOU included removal of contaminated vapors from soil, removal and off-site disposal of contaminated surface soil, monitoring, removal and treatment of contaminated groundwater, and institutional controls. The OU2 remedy included removal of shallow contaminated soils and removal of remaining contaminated vapor in soil. The OU4 remedy included removal and treatment of contaminated groundwater and institutional controls. Under EPA and state oversight, a potentially responsible party completed construction of the WOU remedy in 1999. EPA completed construction of the OU2 remedy in 2006. Because the WOU and OU2 remedies did not adequately address all site contamination, investigations for future cleanup are ongoing. A landscaping business operates on the WOU property. Valley Technologies continues to operate on the OU-2 property during cleanup. Other parts of the site remain in continued residential, commercial, industrial and recreational use.

Westlake Landfill

The 200-acre West Lake Landfill Superfund site is in Bridgeton, Missouri. In 1939, rock quarrying and crushing activities took place on site. Beginning in the early 1950s, operators used parts of the site property as a landfill for municipal solid waste and construction debris. An asphalt/concrete processing plant also operated on the property during quarrying activities. Two areas were radiologically contaminated in 1973 when operators used soils mixed with uranium ore processing residues as daily cover in the landfilling operation. The U.S. Nuclear Regulatory Commission investigated the site in the 1970s. It found two areas affected by radiological materials. EPA added the site to the National Priorities List (NPL) in 1990. Active landfilling of new wastes at the Bridgeton Landfill ceased in 2004 and a waste transfer station subsequently began operating adjacent to the former Bridgeton landfill. In 2008, EPA chose a cleanup plan for radiological and non-radiological areas of the site. Cleanup included installing a landfill cover, restricting future land use and monitoring groundwater. In 2018, EPA amended the cleanup plan for radiological areas of the site. The remedy now includes partial excavation and off-site disposal of contaminated material and placement of an engineered cover over the landfill after excavation. With EPA oversight, the potentially responsible parties (PRPs) are working on the remedies for the radiological and non-radiological areas and are investigating groundwater contamination.  EPA will select a cleanup plan for site groundwater, if appropriate, after the PRPs finish the groundwater investigation. Non-landfill parts of the site remain in industrial use. These uses include continued operation of the solid waste transfer station and the asphalt/concrete batch plant. A tractor-trailer storage facility is located on another part of the site.
