Sites in Reuse in Missouri
Ellisville Site
The Ellisville Site is located in Ellisville, Missouri and consists of three nearby non-contiguous subsites: the Bliss property, the Callahan property, and the Rosalie property. During the 1960s and 1970s, the Bliss Waste Oil Company operated in the transportation and disposal of waste oil products, industrial wastes and chemical wastes. These wastes were disposed of in pits and drums, and on the ground surface at the 11-acre Bliss property. The Callahan property is an 8-acre tract of land where drummed liquid and solid wastes were disposed of during the 1970s. The Rosalie property is a portion of an 85-acre tract of land where drummed liquid and solid wastes were disposed of in and near creeks. All three subsites drain to tributaries of the Missouri River. Area residents rely on drinking water drawn from private wells and the public distribution system. Site investigations discovered that soil at the Callahan and Rosalie properties was contaminated with volatile organic compounds (VOCs) and soil at the Bliss property was contaminated with dioxin and VOCs. The potential for leachate grating into the ground water resulted in the addition of the site to the Superfund National Priorities List in 1983. The remedy for the Callahan and Rosalie properties was selected by EPA in 1985 and included excavation of contaminated soil and drums for offsite disposal, backfilling, capping, and reseeding to control erosion. During the investigation of the Bliss property contamination was discovered on four neighboring parcels: the Dubman and Weingart property, Primm property, Wade and Mercantile Trust Company property, and the Russell, Evelyn, and Jerry Bliss property. In 1986, EPA selected a remedy for these properties, including excavation and offsite disposal of dioxin-contaminated soils, buried drums and other contaminated materials. Cleanup was completed at the Bliss property in 1996 and Callahan and Rosalie properties in 1997. Ground water monitoring continues in accordance with the Record of Decision (ROD). Mid-America Arena developed a portion of the Bliss property to include a large indoor horse arena, stables, and an outdoor riding arena. Rapid residential development is taking place in the area and three occupied residences are located on the site.

Fulbright Landfill
The 98-acre Fulbright Landfill in Springfield, Missouri, accepted industrial and domestic wastes from 1962 to 1968. While investigating the site, EPA and the City of Springfield discovered problems at the nearby Sac River Landfill. In 1983, EPA added the Fulbright Landfill site to its list of hazardous waste sites needing cleanup. The cleanup plan for the site also addressed the Sac River Landfill. EPA, the city, and the parties responsible for the contamination, cleaned up both sites by removing drums and contaminated soils, and disposing of them in an EPA-approved facility off site. The sites' location, near the Little Sac River, is ideal for recreational use. A wastewater treatment plant began operating in 1998 on a portion of the Sac River Landfill property and walking trails are planned for both landfill areas. The plant employs six people.

Minker/Stout/Romaine Creek
Minker/Stout/Romaine Creek site occupies approximately 10 acres of non-contiguous properties near the town of Imperial, Jefferson County, Missouri. In the early 1970's, the Bubbling Springs Ranch horse arena was sprayed with dioxin-contaminated oil for dust control, after which several horses became ill and seven died. The horse arena was excavated in 1972 and the dioxin-contaminated soil was used as fill material in residential areas, including 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 sediments of Romaine Creek as far as 6,000 feet downstream from the properties. The site was added to the Superfund National Priorities List in 1983 and EPA permanently relocated 11 families impacted by the contamination. Between 1985 and 1989, EPA excavated about 28,420 tons of soil at the Minker area, the Sullins and Cashel residences, Romaine Creek, and the Stout area. The contaminated soil was placed in steel storage structures at the Minker area until being transported to the Times Beach site for incineration in 1996 and 1997. Two other families were temporarily relocated by the State during excavation of the Minker area; they have since returned to their residences.

Oronogo-Duenweg Mining Belt
Through the efforts of EPA, the State of Missouri, and the local community, the Oronogo-Duenweg Mining Belt Superfund site in Joplin, Missouri, is the new home of a scrap metal recycling facility, a highway bypass, and numerous residential sub-divisions. The mining, milling, and smelting of lead and zinc ores at the site began in the 1850s and continued in some areas until the 1970s. The smelting operations dispersed airborne contaminants, while the site’s ground water, surface water, and soil became contaminated with lead, zinc, and cadmium. Surrounding human and ecological populations were at risk of lead poisoning from the contaminated ground water. In 1990, EPA added the site to its National Priorities List (NPL). In 1991, the Missouri Department of Health and Senior Services conducted a health study of people who were living in these former mining areas and likely exposed to lead and cadmium. Completed in 1994, the study found that 14 percent of children had increased blood lead levels, with the primary cause being exposure to contaminated soil. EPA devised a plan for time-critical removal of surface soil at local residences. By 2000, EPA had remediated 2,339 residential properties including agricultural lands in the surrounding Joplin communities. Additionally, a scrap metal recycler bought and cleaned up 40 acres of the Oronogo-Duenweg site in exchange for a release from liability for pre-existing contamination. In a separate agreement, EPA, in partnership with the Missouri Highway and Transportation Department, built a highway bypass on another portion of the site. Jasper County received $100,000 through a Superfund Redevelopment Initiative Pilot to consolidate mine tailings for use as fill material for the construction of this new roadway in 2001. Cleanup of the mine waste began in 2007 and Route 249 was opened to the public in October 2008. By the end of 2009, over 400 acres will be cleaned up and ready for redevelopment. The mine waste cleanup action will continue for several more years, ultimately addressing 7000 acres that will be ready for development. The remediation of all the contaminated sections of the Oronogo-Duenweg Mining Belt Superfund site and subsequent development will provide jobs and services, increase annual incomes, and establish a healthy environment for the local community.

Shenandoah Stables
The Shenandoah Stables site occupies approximately seven acres near Moscow Mills, Missouri. In 1971, the horse arena became contaminated with dioxin when a St. Louis waste oil hauler sprayed it with approximately 2,000 gallons of contaminated oil for dust control. Afterward, several adults and children became ill, and numerous birds, rodents, and over 40 horses died. In 1971, the top 6 to 8 inches of contaminated soil were excavated and used as fill material in a new highway. In 1972, an additional 18 inches of soil was removed from the arena and placed in a swampy area on site. EPA sampling in 1982 indicated that the top 30 inches of soil in the arena and soil in the slough are contaminated with dioxin. The site was added to the Superfund National Priorities List (NPL) in 1983. EPA implemented the site cleanup in 1990, which included the excavation and on-site interim storage of 6,542 tons of dioxin-contaminated soils above the 1 part per billion (ppb) action level. Containers of dioxin-contaminated soils were transported to Times Beach for incineration in 1996. Storage structures and fencing on the site were decontaminated following removal of site contaminants. The site was deleted from the NPL in 2001 and remains in use as a horse stable and a private residence.

Times Beach Site
The Town of Times Beach, Missouri, captured the attention of the nation when EPA closed it down after discovering dangerous levels of dioxin, the result of the town regularly spraying dioxin-contaminated waste oil on its streets and parking lots to control dust. Roads to the town were blocked off, and the area was patrolled around-the-clock by security guards. Thus began one of the most extensive cleanups in the Superfund program’s history. After EPA added the site to its National Priorities List (NPL) in 1983, the Agency permanently relocated more than 2,000 people and tore down all of the town’s homes and businesses. By the end of 1997, cleanup of the site was complete, and the state, which now owns the property, took advantage of its easy highway access and riverside location to develop it as a park. A new, 500-acre state park commemorating the famous Route 66 opened in 1999, an impressive transformation for what was one of the most highly contaminated sites in the country. In 2001, EPA deleted the site from the NPL. Thousands of visitors are now able to enjoy the scenic riverside and waterfowl sanctuary, while surrounding communities and farms have slowly begun to repopulate the area.

Valley Park TCE
The Valley Park TCE site is located within the city limits of Valley Park, Missouri. The site boundaries are the extent of a plume of contaminated ground water in the Meramec River alluvial aquifer. In 1982, the Missouri Department of Natural Resources (DNR) detected a number of volatile organic compounds (VOCs), including trichloroethylene (TCE), tetrachloroethene (PCE), and trichloroethane (TCA) in all three municipal water supply wells serving the community. Private wells within the vicinity of the site are also contaminated with VOCs. The site is divided into two OUs: the Wainwright Operable Unit (WOU) and the area wide ground water plume operable unit (OU2). Rays Tree Service currently occupies the former Wainwright property. The OU2 addresses the area-wide ground water plume, including an additional source area located at the property owned by Valley Technologies, Inc.. OU2 includes both commercial and residential properties.

Wheeling Disposal Service Company Landfill
Looking out across the hills of Amazonia, Missouri, you would never suspect that this 200-acre private wildlife reserve was once a Superfund site. The owner of the former Wheeling Disposal Service Company Landfill decided to restore the property to its natural state following cleanup. Bordered on all sides by creeks and ravines, the site is now a habitat for wildlife and birds and is used for recreational hunting and fishing. Before this transformation, the land was contaminated with municipal and industrial wastes containing volatile organic compounds (VOCs) and heavy metals from approximately 15 years of use as a landfill. In 1989, EPA added the site to its National Priorities List (NPL), and afterward chose a cleanup remedy that included upgrading the existing landfill cap with a clay and soil cover and monitoring ground and surface water. During cleanup, the owner dug a pond and, with assistance from the state, planted native wild grasses and other foliage to attract birds and wildlife. Remediation was completed and the site became ready for reuse in 1994. In 2000, EPA deleted the site from its NPL. As a result of the efforts of EPA, the state, and the owner, this former landfill is now an important source of habitat for local flora and fauna.
