12th Avenue Solvents

The 12th Avenue Solvents site is in Ava, Missouri. It includes four properties: the former Emerson Electric Company facility, the former Rawlings facility, part of the Douglas County Health Department and part of the Sentinel Wood Treating Superfund site. Since 1968, companies have used the area for manufacturing activities. These activities contaminated site soil and groundwater. From 1994 to 2000, Emerson Electric Company, the potentially responsible party (PRP), led a series of time-critical removal actions on site. Actions included installing and sampling three groundwater monitoring wells under the southwest part of the facility. They also included installing a dual-purpose groundwater and soil vapor extraction well and a dual vapor extraction (DVE) system and removing and treating about 57 tons of soil. In 2001, EPA, the Missouri Department of Natural Resources (MDNR) and the PRP signed an agreement. The PRP agreed to continue the cleanup through a non-time-critical removal action. EPA’s long-term cleanup plan includes groundwater treatment and land use restrictions. Due to perceived risks, office space in only one of the warehouse buildings was in use. The PRP did a vapor intrusion assessment. It confirmed indoor air safety. In 2021, a beehive manufacturing company purchased the warehouse. The company is upgrading the warehouse and putting in a new loading dock. Other uses on site include a police station, a heating, ventilation, air conditioning and refrigeration manufacturing business, and other commercial businesses.

Annapolis Lead Mine

The 200-acre Annapolis Lead Mine Superfund site is in Iron County, Missouri. It 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 (MoDNR) 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 excavated and combined contaminated materials and capped them. EPA and MoDNR 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 MoDNR tested soils and removed contamination. Studies focused on areas attractive to children, such as residential yards, school yards and church yards. Remedy construction finished in 2007. EPA deleted the site from the NPL in 2020. MoDNR continues to inspect the site and conducts regular maintenance activities to make sure 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, several different parties ran an herbicide mixing and packaging facility on the 1.8 acre site property. A 1989 environmental assessment found high levels of arsenic and other herbicide-related contaminants in soil and groundwater. To protect public health and the environment, EPA conducted a time-critical removal action. EPA covered the site property with geofabric and crushed rock and put a perimeter fence around the property in May 1996. EPA added the site to the National Priorities List (NPL) in 1999. Under EPA oversight, the site’s responsible parties continued cleanup activities. From August 2004 to October 2004, a removal action was conducted to decontaminate and demolish the building and foundation and to dispose of construction debris in a permitted landfill. Another removal action was conducted from March 2005 to April 2006 to excavate contaminated soil from the site property, to dispose of contaminated soil off-site in a permitted landfill and to backfill with clean soil. The most recent soil cleanup was completed in January 2017 to excavate, treat and dispose of contaminated soil in a permitted landfill from beneath Railroad Avenue to the east and south of the site property and the adjacent property to the west. Soil cleanup at the site is complete. EPA continues to work with the responsible parties on the final groundwater remedy. Cleanup enabled the reuse of the site property and opened the door to redevelopment opportunities in the area. In 2016, Northern Kansas City released its Northern Kansas City Master Plan. It included the site as part of a large redevelopment project called the One North Redevelopment Area. To date, redevelopment at and around the site includes a medical center with a solar array on its covered parking lot and a fast-food restaurant. Road realignments and extensions across the site facilitate access to the larger One North Redevelopment Area, improving traffic flow and establishing a gateway to North Kansas City’s downtown. In September 2019, EPA Region 7 presented its Leading Environmentalism and Forwarding Sustainability (L.E.A.F.S.) Award to Northern Kansas City and Rio Tinto Mining Company, one of the site’s responsible parties. Today, EPA continues to work with the local government to facilitate property transactions and construction planning, ensuring the long-term protectiveness of the site’s remedy and supporting the site’s successful redevelopment.

Big River Mine Tailings/St. Joe Minerals Corp.

The 110-mile Big River Mine Tailing/St. Joe Minerals Corp. Superfund site is in Desloge, Missouri. From 1742 to 1972, mining operations resulted in enormous piles of mine waste tailings and chat on site. The site includes eight large areas of mine waste. In 1977, heavy rains caused 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. 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. EPA added the site to the National Priorities List (NPL) in 1992. The cleanup includes mine waste removal and stabilization as well as treatment of dissolved zinc in groundwater seeps. Land uses at the site include residential, commercial, industrial, recreational, public services, agricultural and ecological areas. EPA and potentially responsible parties test residential properties, schools, daycares and parks for heavy metals, and replace contaminated soil as needed. In 2019, EPA’s Superfund Redevelopment Program (SRP) started a regional seed project to work on a reuse assessment for the site. It identified 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 followed. In 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.

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. The dioxin-contaminated soil from the horse arena was later used as fill material in local residential areas. These areas included the Minker, Stout, Cashel and Sullins homes where much of the fill from the Minker residence eroded into Romaine Creek. In 1983, EPA found dioxin in soil on site and in Romaine Creek sediments. EPA added the site to the National Priorities List (NPL) in 1983 and permanently relocated 11 families affected by the contamination. From 1985 to 1989, EPA removed approximately 26,420 tons of soil from the Minker/Stout/Romaine Creek site. The contaminated soil was then transported off-site for incineration at Times Beach in 1996 and 1997. In all but one area at this site, cleanup levels were achieved in excavating dioxin-contaminated soils exceeding one part per billion (ppb) to a maximum depth of four feet or bedrock. The singular area at a depth of four feet containing residual concentrations of up to 266 ppb remains covered by clean backfill with permanent survey markers to distinguish itself on the Minker area of this site. EPA completed cleanup in 1997 and the site remains in continued residential use.

The Missouri Electric Works Superfund Site consists of soil and groundwater impacted by polychlorinated biphenyls, or PCBs, related to servicing and remanufacturing electric equipment. The site property is 6.4 acres located adjacent to U.S. Highway 61 (South Kings Highway) in Cape Girardeau, Missouri. Missouri Electric Works, Inc., sold, serviced and remanufactured electric motors, transformers and equipment controls at the site property from 1953 to 1992. During most of its time in operation, the company processed electrical equipment that was filled with oil containing PCBs. Part of the operations were to recovery oil from electrical equipment and to recycle or dispose of the oil. These operations resulted in soil and groundwater contaminated with PCBs. During a facility inspection in 1984, the Missouri Department of Natural Resources found soil contaminated with PCBs and over 100 drums containing PCB-contaminated oil. EPA added the site to the National Priorities List (NPL) in 1990. EPA did more investigations from 1985 to 1988 to characterize the contamination. The soil cleanup included the excavation, processing and treatment of PCB-contaminated soils using thermal desorption technology. On-site construction activities to implement the remedy began in June 1999 and were completed in September 2000. The remedial action at OU01 has been completed and achieved cleanup levels for soil. Groundwater monitoring and institutional controls address the two groundwater aquifers affected by site contamination. Groundwater monitoring is ongoing. Land use restrictions limit the use of the site property to industrial and commercial uses. In 2010, a buyer bought and redeveloped the property. The renovated former facility building now hosts a commercial business. A self-storage facility is also on site.

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. 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 initiating work on backlogged remedial construction projects and accelerating cleanups at NPL sites. Collaboration among EPA, the state of Missouri and the community resulted in innovative approaches to encouraging new productive uses. 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 that was cleaned up by EPA. The Route 249 Development Plan contains details on zoning, land use and institutional controls to facilitate sustainable development while protecting human health. Cleanup of a 12-acre former mine pit and waste area provided new level areas that supported a 23-acre expansion and infrastructure improvements at neighboring King Jack Park. 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. Former mining land in Webb City has been transformed into the 300-acre Centennial Park development. New businesses there include a farm and home goods retailer, restaurant and hotel. Nearby, a new 1.3-mile trail provides public access to the Cardinal Valley Habitat Restoration Project. The 740-acre project features restored prairie, wetland, woodland and pollinator habitat on former mining lands. The site continues to support other residential, agricultural, commercial, industrial and public service uses. Joplin is experiencing strong demand for new housing and many areas of remediated mine lands are being turned into residential areas, under the guidance of the Jasper County Contamination Ordinance that requires testing prior to building any new residential developments as a part of the site’s Institutional Controls. Additional reuse planning is underway. Over 4,000 acres of cleaned-up land are ready for redevelopment.

Riverfront

The 321-acre Riverfront Superfund site is in New Haven, Missouri. In 1986, the Missouri Department of Natural Resources found that the public water supply wells on site were contaminated with industrial chemicals. EPA identified six different areas of concern where different sources contributed to the contamination. EPA added the site to the National Priorities List (NPL) in 2000. Cleanup includes groundwater monitoring and use restrictions, land use restrictions, treatment of soil and groundwater contamination, and installation of water treatment units for area homes. Contaminated groundwater vapor in one home resulted in the decision to relocate one resident. 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. Today, the site supports new and continued uses. One site area is now a New Haven Public Works Department yard waste/gravel storage and composting area. After cleanup of this area finished, EPA and the state of Missouri took it off the NPL in September 2021. Another site area is now a part of an industrial park that hosts warehouses and manufacturers. On part of the site near the Missouri River, a bed and breakfast, distillery, brewery and kayak/paddleboard manufacturer attract people visiting area wineries.

Shenandoah Stables

The 7-acre Shenandoah Stables Superfund site is near Moscow Mills, Missouri. In 1971, a St. Louis waste oil hauler sprayed the horse arena with about 1,500 gallons of dioxin-contaminated oil for dust control. Afterward, several adults and children became ill, and many birds, rodents and horses died. In 1971, site operators removed contaminated soil for use as fill material for a new highway. In 1972, site operators disposed of more soil from the arena in a swampy area on site. EPA sampling in 1982 confirmed dioxin contamination of the arena soil. EPA added the site to the National Priorities List (NPL) in 1983 and started cleanup in 1990. The cleanup included the removal and off-site burning of 6,452 tons of dioxin-contaminated soils. After the removal of contaminants, the cleanup of storage structures and fencing further protected public health and safety. Remedial action was completed in 1997 and EPA took the site off the NPL in 2001. Today, the site is used as commercial and agricultural property.

Southwest Jefferson County Mining

The Southwest Jefferson County Mining Superfund site includes all of Jefferson County, except for the Herculaneum site. Jefferson County is located in the northern portion of an area known as the Old Lead Belt. Heavy metal mining began there in the early 1700s. Industrial mining started in this area in the 1800s. By 1855, three active smelters and many mines were operating in Jefferson County, with over 3 million pounds of lead shipped annually from the county. Mine waste has contaminated soil, sediment, surface water and groundwater with lead and other heavy metals. Mine waste has been transported by the Big River and it has been used in residential areas as topsoil, fill material and aggregate for roads throughout the county. Sampling began in 2004 and more assessment work continued in 2007. In 2007, EPA began removal activities, digging up contaminated residential soils and taking them off site for disposal. EPA added the site to the National Priorities List (NPL) in 2009 and continued its cleanup efforts. Cleanup included backfilling and revegetation of these areas. The remedy also included health education for residents and institutional controls to protect areas from lead recontamination. A remedial investigation and feasibility study for the Big River and floodplain are ongoing. 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. Current site uses include residential, commercial, industrial, ecological, public service and recreational areas.

St. Louis Airport/Hazelwood Interim Storage/Futura Coatings Co.

The St. Louis Airport/Hazelwood Interim Storage/Futura Coatings Co. Superfund site, also known as the Formerly Utilized Sites Remedial Action Program (FUSRAP) site, is in St. Louis City and St. Louis County, Missouri. It includes two areas – the St. Louis Downtown site and the North County site. The St. Louis Downtown site includes the Mallinckrodt Chemical Plant and 63 nearby properties. From 1942 to 1957, under contracts with the U.S. government, operators processed uranium ore on site. Byproducts containing radioactive residuals went to properties near the St. Louis Airport during this same period. In 1966, some of this byproduct material was moved about a half-mile northeast, to property on Latty Avenue, for interim storage. From 1977 to 1986, the U.S. Department of Energy brought more contaminated soils to the Latty Avenue properties. Residues from these operations contaminated other properties nearby as well as Coldwater Creek. Coldwater Creek flows through northern St. Louis County until it discharges into the Missouri River. The North County site consists of the St. Louis Airport site properties and the Latty Avenue properties (including the Hazelwood Interim Storage site and the Future Coatings Company). It also includes Coldwater Creek, which extends 15 miles from the St. Louis Airport site to the Missouri River, and over 148 nearby properties located along haul routes and in the 10-year floodplain of Coldwater Creek. EPA added the North County site to the National Priorities List (NPL) in 1989. The U.S. Army Corps of Engineers manages cleanup activities. EPA provides oversight. Cleanup includes soil removal and disposal. Sampling and cleanup are ongoing. Commercial and industrial businesses, homes and recreation areas are on site. These areas include stores as well as metal salvage and steel fabrication facilities. The areas also include residential properties and parks in the 10-year floodplain of Coldwater Creek, and a section of the St. Louis Riverfront Trail. Public service uses are also on site. These uses include railroad lines, bridges and part of a floodwall that protects the St. Louis area from Mississippi River floodwaters. There is also a timber salvage yard on site.

Syntex Facility

The Syntex Facility Superfund site is in Verona, Missouri. Prior to development, the 180-acre area along the Spring River was for agricultural and recreational purposes. Hoffman-Taff constructed a facility began making chemicals on site in the 1960s for the U.S. Department of Defense as part of the production of Agent Orange. Hoffman-Taff leased part of the facility to Northeastern Pharmaceutical and Chemical Company (NEPACCO) for production of hexachlorophene, a chemical antiseptic. Syntex Agribusiness (Syntex) bought the facility in 1969, with NEPACCO continuing to operate until 1972. 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 waste management and disposal practices at the facility in 1979. EPA added the Syntex facility to the National Priorities List (NPL) in 1983. Contaminated soils were addressed by a combination of excavation and treatment, capping, and revegetation. Aquifers in the surrounding areas are used by rural households for domestic purposes and some agriculture and by water utilities and large-scale agricultural operations. In 1996, Syntex sold the East Area of the Site to DuCoa, L.P. In 2001, DuCoa, L.P. sold the East Area to BCP Ingredients, Inc., which is the current owner of the East Area and operator of the facility. The facility makes human-grade and feed-grade choline chloride products. The West Area is not in use and remains owned by Syntex.

Times Beach

The 1-square-mile Times Beach Superfund site is 20 miles southwest of St. Louis, Missouri. The site is a former city that sprayed its roads with waste oil to control dust in the early 1970s. In 1982, EPA found that the city had used dioxin-contaminated oil. During the same period, the Meramec River flooded the city and residents evacuated their homes. The Centers for Disease Control and Prevention (CDC) recommended the permanent relocation of evacuated residents. EPA added the site to the National Priorities List (NPL) in 1983. EPA transferred funds to the Federal Emergency Management Agency for the permanent relocation of residents and businesses. All residents relocated by the end of 1986. The state of Missouri took ownership of the site. Cleanup activities finished in 1997. In 1999, Missouri opened Route 66 State Park at the site and EPA took the site off the NPL in 2001. Route 66 State Park includes a section of the historic roadway, including a 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 amenities include a visitor’s center, picnic areas and a boat ramp that provides access to the Meramec River. In 2012, EPA reassessed the park to see if any residual dioxin contamination remained above a recently revised cleanup goal. The reassessment found that the current use of 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. The Site consists of two source areas: the Wainright Industries and current Valley Technologies properties. Wainright Industries owned and operated a metal stamping and tool and die shop at the site from 1949 to 1979. Part of the manufacturing process included a solvent degreasing system that used the solvents TCE from 1963 to 1970 and PCE from 1970 to 1979. Wainwright Industries and Valley Technologies used the area for metal processing. Wainwright Industries stopped operating on site in 1979. Several other businesses were active at the former Wainwright Industries property. Beginning in 1954, Valley Technologies operated two divisions in Valley Park, Missouri: Prevision Forgings and Valley Heat Treat. It began operating solely as Valley Technologies in the early 2000’s. Precision Forgings manufactured aluminum pressings, and Valley Heat Treat provided heat treatment services on metal parts. Valley Technologies still operates a metal processing facility at the Operable Unit 2 (OU02) source area. EPA added the site to the National Priorities List (NPL) in 1986. Cleanup activities at the Wainright Industries source area include soil vapor extraction (SVE) of contaminated soil, removal and treatment of contaminated groundwater, institutional controls, and groundwater monitoring. Construction of the Wainright Industries source area remedy finished in 1999. Cleanup activities at the Valley Technologies source area included treating shallow soils with SVE, in-place SVE treatment of deep soils, removal and treatment of contaminated groundwater with air stripping, institutional controls, and groundwater monitoring. Construction of the Valley Technologies source area remedy finished in 2007. Because the cleanup did not adequately address all contamination, investigations for future cleanup are ongoing. EPA issued a Record of Decision (ROD) for the Wainright Industries source area in 2000 that changed the soil remedy to thermal treatment. Remedial design began in 2022 and is ongoing. EPA issued a RPD amendment for the Valley Technologies source area in 2020 that changed the soil remedy to thermal remediation. EPA completed the remedial design in 2022. The remedial action is ongoing. In 2021, OU02 was selected by EPA to receive cleanup funding under the Bipartisan Infrastructure Law (BIL). This funding will be used to address soil contamination at OU02, the Valley Technologies soil source area. With this funding, EPA is already initiating work on backlogged remedial construction projects and accelerating cleanups at NPL sites. Several commercial businesses are active on site. Valley Technologies also continues to run its metal-processing facility on site.

The site includes about 533 square miles of southeast, southwest and northwest Washington County, and is about 65 miles southwest of St. Louis. The communities of Belgrade, Caledonia, Irondale, Courtois and Pea Ridge are within the site boundaries. The Mark Twain National Forest resides in the southwest portion of the Site. This area was one of the world's largest lead mining districts. Washington County has hosted over 1,000 lead and barite mining, milling or smelting sites. Remnants of mining activities include strip mines, mineshafts, mine dumps, tailing areas, tailings ponds and associated dams. Mining practices contaminated soil, groundwater, surface water, and sediment with heavy metals. It has been reported that mine waste was used on residential properties for fill material, in private driveways, parking areas, as sand in play areas, and as an aggregate used in road construction. EPA added the site to the National Priorities List (NPL) in March 2011. In 2008, a removal action by EPA cleaned up lead-contaminated soil in residential yards and provided water filtration systems to homes where lead in the water exceeds health-based levels. Cleanup of lead-contaminated soil in residential yards is ongoing. It includes replacing excavated material with clean fill and vegetative cover. To date, about one in eight private drinking water supply wells qualify for a water filtration system. Investigations and cleanup at the site continue. In December 2021, the site was among those selected by EPA to receive cleanup funding under the Bipartisan Infrastructure Law (BIL). This funding will be used to conduct cleanup of lead-contaminated soil at residential properties. Today, continued uses at the site include residential, commercial and industrial areas. The area’s ecological and recreational resources include parts of several national forests and conservation areas. The site also hosts key habitat for the Indiana bat and includes a network of streams and other hydrological features.

Westlake Landfill

The 200-acre Westlake 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 was also on the property during quarrying activities. In 1973, operators used soils mixed with uranium ore processing residues as daily cover in the landfilling operation, resulting in radiological contamination of two areas. 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 later opened next to the former Bridgeton landfill. In 2008, EPA chose a cleanup plan for the site. Cleanup included putting in a landfill cover, restricting future land use and monitoring groundwater. In 2018, EPA amended the cleanup plan for radiological areas of the site. The cleanup now includes partial digging up and off-site disposal of contaminated material and placement of an engineered cover over the landfill. With EPA oversight, the potentially responsible parties (PRPs) are working on the cleanup of 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 the solid waste transfer station and asphalt/concrete processing plant. A tractor-trailer storage facility is on another part of the site.
