ALCOA PROPERTIES

The 400-acre Alcoa Properties Superfund site is in East St. Louis, Illinois. From about 1902 to 1957, Alcoa refined aluminum at the site. Smelting wastes contaminated soil and groundwater. The area is not on the National Priorities List (NPL). The site is being addressed through the Superfund Alternative Approach (SAA). EPA oversees the potentially responsible party’s cleanup. Investigations began in 2001. They are ongoing. To manage the cleanup, EPA divided the site into three areas, or operable units (OUs). The cleanup addresses smelting waste and soil (OU1), soil contamination (OU2) and groundwater (OU3). OU1 cleanup finished in summer 2016. It included consolidating and covering smelter wastes. OU2 cleanup includes waste excavation, a soil cover, reassessment of existing stormwater runoff controls, revegetation, institutional controls and monitoring for indoor radon. OU2 remedy construction was substantially completed in fall 2023.. EPA plans to issue a Proposed Plan for the final remedial action for OU3 in 2026. Commercial uses are active on the OU2 part of the site. At the request of EPA, the PRPs evaluated solar redevelopment as part of the OU1 remedy design. The City continues to pursue potential solar redevelopment opportunities at the site.

BELOIT CORP.

The 175-acre Beloit Corp. Superfund site is in Rockton, Illinois. From 1957 to 1999, industrial operators ran a research center and made machines that produced layered paper products from paper pulp on site. These manufacturing activities resulted in contamination of area soil and groundwater. EPA added the site to the National Priorities List (NPL) in 1990. EPA put in a groundwater treatment system and put land use controls in place to prohibit potable water wells on site. The Illinois Environmental Protection Agency (IEPA) has operated the treatment system since 2002. A grease, lubricating oil and fluids manufacturer relocated its distribution and field support operations to the site in 2008 and upgraded the facility. Another industrial business as well as several other commercial businesses are also on site. The site also includes part of a residential subdivision. EPA deleted part of the site from the NPL in December 2018. Impacts associated with a fire in 2021 at the neighboring Chemtool facility were assessed by EPA and IEPA. Due to the use of polyfluoroalkyl substance (PFAS)-containing fire suppressant, PFAS sampling has become part of the routine groundwater sampling of the treatment system.

BYRON SALVAGE YARD

The Byron Salvage Yard Superfund site is in rural Ogle County, Illinois. It consists of the 22-acre Byron Salvage Yard Property and the 150-acre Dirk’s Farm Property. From the 1960s to 1972, a junkyard and dump for miscellaneous waste and debris – Byron Salvage Yard – was active on-site. Disposal practices at the junkyard and the farm, including accepting drums of hazardous waste and dumping industrial wastes on the ground, resulted in contamination of groundwater and soil with volatile chemicals, metals and cyanide. In 1975, cleanup activities removed drums and treated contaminated soils. EPA added the site to the National Priorities List (NPL) in 1982. Cleanup included removal of more buried drums and contaminated soils, soil covering, groundwater use restrictions, alternate water sources for affected homes, drinking water filtration and fencing. In 1987, Illinois EPA finished disposing of 11,000 drums and 3,000 cubic yards of contaminated soils. Nearby homes connected to the public water supply. Groundwater monitoring is ongoing. Commercial and residential uses at or near the Byron Salvage Yard Property are ongoing. The Dirk’s Farm Property consists of farmland and open space.

CELOTEX CORPORATION

The Celotex Corporation site is in Chicago’s Little Village neighborhood. For decades, manufacturing facilities made asphalt roofing materials on-site. These operations contaminated the property and nearby residential yards. After investigations by the Illinois Environmental Protection Agency, Celotex Corporation removed on-site buildings and placed gravel across the area to help address flooding and off-site contamination. Cleanup of residential yards followed. The city of Chicago, the Chicago Park District and community organizations, such as the Little Village Environmental Justice Organization, prioritized the area’s reuse as a community resource. To address potential Superfund liability issues for the locality, EPA developed a Prospective Purchaser Agreement, or PPA. It enabled the city to acquire the property and pursue redevelopment plans. With few parks in the community, the site offered a valuable opportunity for new recreation facilities. The city purchased the site in 2012. La Villita Park opened to the community in 2014. The complex includes athletic fields, a skate park, basketball courts, community gardens, a playground and splash park, a picnic pavilion, concession areas, a multi-use trail with fitness stations, and environmentally friendly utilities. Since park planning started, community perspectives have been a vital part of the process. Community members were involved in the park’s design and naming and are involved in ongoing development of park programming. In 2022, the Little Village Environmental Justice Organization opened La Villita Community Farm at the park. The 1.3-acre farm is an informal agricultural school for community members. Small-scale Indigenous farming practices are part of its operations.

CIRCLE SMELTING CORP.

The 28-acre Circle Smelting Corp. Superfund site is in Beckemeyer, Illinois. A zinc refinery was on-site from 1904 to 1994. Operators discarded residual metals, coal cinders and slag from the smelting process in piles on the property. Those disposal practices resulted in elevated concentrations of lead, zinc, cadmium, nickel and copper in the soil. Lead-contaminated materials from the facility were also used in walking paths, driveways and alleys in Beckemeyer. In 1996, EPA proposed adding the site to the National Priorities List (NPL). Cleanup activities began in 1998. They are ongoing for parts of the site. EPA has cleaned up over 300 properties. EPA removed contaminated soil from the smelter property, the village and nearby wetlands, and placed it under a concrete cover. A local trucking company purchased a cleaned-up part of the site property and paved it for use as a parking lot. A prospective purchaser agreement (PPA) signed by the trucking company and EPA in 1999 made the acquisition possible. A PPA encourages the reuse of Superfund site properties by addressing purchaser and lessee liability concerns. The PPA limits the company’s liability in exchange for sharing the costs of cleanup. The trucking company remains active on-site.

The DePue/New Jersey Zinc/Mobil Chemical Corp. Superfund site is in the village of DePue in Bureau County, Illinois. The 950-acre area includes Lake DePue and borders the DePue-Donnelly Wildlife Management Area. Starting in 1903, New Jersey Zinc ran zinc smelting facilities on a stretch of former farmland. New Jersey Zinc built more facilities in 1967 to produce phosphate-based fertilizers. Mobil Chemical Corporation began leasing these facilities in 1972 and purchased them in 1975. The Illinois Environmental Protection Agency (Illinois EPA) and EPA inspected the site. They found heavily contaminated surface water and groundwater. EPA added the site to the National Priorities List (NPL) in 1999. Site cleanup has included water treatment, removal and containment of contaminated sediments, and capping and revegetation of other site areas. Cleanup of residential areas started in 2020 and is ongoing. Investigations of other site areas are ongoing. With assistance from EPA’s Superfund Redevelopment Program (SRP), the village of DePue (the Village) developed a reuse plan for the site in 2004. The plan later informed the 2014 DePue Comprehensive Plan adopted by the North Central Illinois Council of Governments. Today, the Village hosts the National Power Boat Racing Association’s races, held each summer on Lake DePue. Ponds and wetlands areas are also on site. White City Park and Lake Park provide baseball and softball fields, a playground and picnic areas. Other site uses include commercial, industrial, public service and agricultural areas. A solar array is present on a portion of the site.

DUPAGE COUNTY LANDFILL/BLACKWELL FOREST PRESERVE

The 40-acre DuPage County Landfill/Blackwell Forest Preserve Superfund site is in the 1,200-acre Blackwell Forest Preserve in Warrenville, Illinois. DuPage County established the landfill intending to create a hill to serve as a recreation amenity. It accepted waste from 1965 to 1973. Known as Mt. Hoy, the resulting mountain of waste and soil rises 150 feet above the original ground surface. EPA identified contamination in groundwater. EPA added the site to the National Priorities List (NPL) in 1990. EPA’s cleanup repaired the landfill cap, put in a landfill gas extraction system and a leachate collection system, treated and disposed of the landfill leachate, and put in more landfill gas vents. EPA continues to monitor the natural breakdown of groundwater contamination. Use controls restrict land and groundwater use. Cooperation among EPA, Illinois EPA and the site’s potentially responsible party enabled the forest preserve to address potential risks while maintaining public access to recreation and conservation activities. An on-site recreation area features restored native prairie vegetation, picnic areas, trails, an observation area and a snow tubing run on Mt. Hoy. Other recreation and education activities – including two lakes used for fishing, an archery range and an urban stream research facility – are next to the site. They are also in the Blackwell Forest Preserve. EPA took the site off the NPL in September 2020.

ELLSWORTH INDUSTRIAL PARK

The Ellsworth Industrial Park site is an industrial area in Downers Grove in DuPage County, Illinois. Built in the late 1950s, the industrial park includes about 135 businesses. Several businesses at the facility used solvents containing volatile organic compounds (VOCs). Trichloroethylene (TCE), tetrachloroethylene (PCE) and trichloroacetic acid (TCA) migrated from source areas to private drinking water wells in unincorporated areas of Downers Grove. Sampling found groundwater contamination in 2001. In 2004, about 800 homes to the south and east of the industrial park connected to the public drinking water supply. EPA did not add the site to the National Priorities List (NPL). It is an NPL-caliber site. EPA addresses it through the Superfund Alternative Approach (SAA). Cleanup includes digging up and removing contaminated soil, replacing it with clean fill, and treating deeper soil and groundwater in place. It also includes preventing the collection of harmful chemical vapors from the soil inside buildings. Groundwater investigations are ongoing. Current site uses include dozens of commercial and industrial businesses and non-profit organizations, homes, public services and a creek.

EVERGREEN MANOR GROUND WATER CONTAMINATION

The Evergreen Manor Ground Water Contamination Superfund site is a 2-mile-long area of groundwater contamination in Roscoe Township, Illinois. Sampling found the contamination in 1990. Investigations found that contamination came from former waste disposal practices at three companies, Waste Management, Regal-Beloit and Ecolab, located near the intersection of Route 251 and Rockton Road. The area of contamination extended to the Rock River. After initially proposing the site for listing on the National Priorities List (NPL) in 1999, EPA managed the site using the Superfund Alternative Approach. Cleanup included natural processes to help break down contaminants in groundwater and monitoring. Restrictions on groundwater use prevented exposure to contamination. Today, cleanup is complete. Groundwater complies with safe drinking water standards. Residential, agricultural, commercial and industrial areas above the groundwater contamination remain in continued use. Waste Management, Regal-Beloit and Ecolab remain active on-site.

H.O.D. LANDFILL

Playground equipment at Osmond Sports Complex
H.O.D. Landfill

The 121-acre H.O.D. Landfill Superfund site is in Antioch, Illinois. It includes a former landfill and 70 acres of undeveloped land that served as a buffer area for the landfill. From 1963 to 1984, the landfill accepted municipal and industrial waste. In 1984, Waste Management closed and capped the landfill. Its operations resulted in groundwater contamination. EPA added the site to the National Priorities List (NPL) in 1990. Cleanup included landfill cap repairs, leachate treatment and upgrades to the landfill’s gas and leachate extraction system. The site’s potentially responsible parties (PRPs) also began monitoring groundwater and placed land use restrictions on the property. Remedy construction finished in 2001. EPA worked with the community on a reuse plan in 2002. EPA issued a Ready for Reuse Determination for the site in 2003. It highlighted the compatibility of the remedy with recreational uses. The school district expressed interest in using methane gas produced by the landfill. After construction of a methane co-generation plant, methane gas from the landfill supplied heat and electricity to Antioch Community High School from 2003 to 2013. Today, recreational resources at the site include a playground, a concession stand and restroom building, and athletic fields for soccer, baseball, softball and field hockey. Area schools use on-site wetlands as an environmental education resource.

HEGELER ZINC

The 149-acre Hegeler Zinc Superfund site is in Danville, Illinois. From 1906 to 1954, Hegeler Zinc used the area for zinc smelting, cadmium processing and sulfuric acid production. Afterward, several other companies used the area for insecticide packaging and fireworks storage and manufacturing. Workers stored wastes on-site. Emissions deposited heavy metals on the ground in the area. This contaminated soil, groundwater, surface water and sediment at the facility as well as soil on nearby residential properties. Investigations by the Illinois Environmental Protection Agency began in 2001. EPA added the site to the National Priorities List (NPL) in 2005. Cleanup of 39 residential properties included digging up, removing and disposing of contaminated soil from the yards and backfilling the areas with clean soil. EPA completed residential yard cleanups in 2016. The homes are in continued use. In 2023, EPA selected long-term remedies for the former smelter facility and an un-named tributary to Grape Creek. EPA’s cleanup will involve digging up contaminated sediment and soil and adding it to the existing slag pile or taking it off-site for disposal. EPA will then place a low-permeability cover over the pile, reroute parts of a creek away from the slag pile, and continue monitoring groundwater and surface water.

ILADA ENERGY CO.

The 17-acre Ilada Energy Co. Superfund site is next to the Mississippi River levee in a rural area southeast of East Cape Girardeau, Illinois. In 1942, the federal government built and operated a tank farm at the site. Several companies ran the tank farm until 1981, when Ilada Energy Company took over operations. The firm put in more tanks and structures and operated a waste oil reclamation facility. In the 1980s, investigations found contaminated sludge, soil, liquid oil waste and groundwater resulting from improper storage, use and disposal of waste oil. Ilada Energy Company ended operations at the site in 1983. EPA added the site to the National Priorities List (NPL) in 1989. The potentially responsible parties (PRPs) led cleanup activities, removing all tanks and their contents as well as piping, structures, debris and contaminated soil. The PRPs completed the removal activities in 1991. In 2001, EPA took the area off the NPL. The current site owner purchased the property in 2006. The owner has not identified any plans for building on the property. The owner uses the area for recreation activities. The site is swampy and supports ecological use, providing habitat for native grasses and weeds as well as aquatic plants. The U.S. Forest Service maintains the forest next to the site.

JOHNS-MANVILLE CORP.

The Johns-Manville Corp. Superfund site covers approximately 350 acres in Waukegan, Illinois. From the 1920s to 1998, an asbestos manufacturing facility with several waste management features including landfills were active on-site. Disposal practices resulted in air, groundwater and surface water contamination with asbestos and metals. EPA added the site to the National Priorities List (NPL) in 1983. Cleanup activities included consolidating waste, placing clean soil and establishing vegetation over waste disposal areas, placing sand and gravel onsite roadways, installing stormwater drainage features, institutional controls, and periodic sampling of air, soil, and groundwater. All former manufacturing buildings were demolished in 2000 and 2001. The remedy also included putting barriers in place to prevent contact with contamination. These barriers included engineered capping systems across various site features with vegetated soil cover, fencing and signage. Sampling identified additional areas of asbestos contamination outside of the site perimeter fence. Cleanup of these areas are complete, with the exception of a 1-acre disposal area that extends into an adjacent nature preserve. EPA oversaw large scale air-sampling in the Illinois Beach Nature Preserve area north of the Johns Manville site in 2023 and 2024. Inspections, maintenance and groundwater monitoring are ongoing. A utility corridor crosses the site. In 2016, several piping plovers, rare birds protected by the Endangered Species Act, established a nesting area at the site. This inspired a community-led exploration of ecological reuse opportunities. The site now serves as a buffer between the nature preserve to the north and industrial land use to the south.

KERR-MCGEE (REED-KEPPLER PARK)

The Kerr-McGee (Reed-Keppler Park) Superfund site is one of four areas associated with radioactive waste contamination in West Chicago, Illinois. The site spans 11 acres of a larger 90-acre area. A sand-and-gravel quarry was active on parts of the 11-acre site in the early 1900s. The area also hosted a small municipal landfill, which received waste as fill material for the quarry, from the 1930s to 1974. The landfill accepted waste materials, including radioactive tailings from the nearby Rare Earths Facility. Operators used the mill tailings to cover the landfill and provide fill for the surrounding park. Parts of the landfill area were fenced in the 1970s. EPA added the site to the National Priorities List (NPL) in 1990. Investigations at the park in 1993 found small areas of contamination scattered across the site in addition to the landfilled area and identified groundwater contamination. Prior to cleanup, the community expressed interest in redeveloping the area as an aquatics center. EPA worked with the local park district on a focused investigation for the proposed development area. The park district identified potential areas of contamination that required modification of the building plans for the aquatic center to avoid contaminated areas. The Prairie Oaks Family Aquatic Center opened on-site in 1995. Cleanup activities for other parts of the site removed all contaminated soil between 1997 and 2000. In 2010, EPA took the site off the NPL. The site can accommodate unrestricted use. Reed-Keppler Park now features sports fields, a skateboard park, two playgrounds, a concession stand, pavilions, a 25-acre nature sanctuary, a dog park and parking. The park is also home to the West Chicago Park District Wildcat Youth Football League. In 2022, the local park district commemorated its 50-year anniversary with a public celebration at the park. Commercial and industrial businesses and a water park are also on-site.

KERR-MCGEE (RESIDENTIAL AREAS)

The Kerr-McGee (Residential Areas) Superfund site is in West Chicago, Illinois. From 1932 to 1973, operations at the Rare Earths Facility, located nearby, produced non-radioactive elements known as rare earths, radioactive elements and gas lantern mantles. Production of these compounds generated radioactive waste. Before the health risks associated with radioactive materials were known, residents and contractors used the waste as free fill material. Wind may have also spread the waste to nearby properties. Kerr-McGee bought the Rare Earths Facility in 1967 and ran operations until 1973. Radioactive materials from windblown contamination and the use of the waste as fill material contaminated site properties in the West Chicago area. EPA added the site to the National Priorities List (NPL) in 1990. Cleanup included soil sampling and cleanup at hundreds of properties. Many commercial businesses and a public library are in use on-site today. Continued uses at the site include residential, institutional, commercial, industrial and municipal areas.

KERR-MCGEE (SEWAGE TREATMENT PLANT)

The Kerr-McGee (Sewage Treatment Plant) Superfund site is in West Chicago, Illinois. It includes the 25-acre West Chicago Sewage Treatment Plant and about 1.2 miles of West Branch DuPage River’s sediments, banks and floodplain soils. The city of West Chicago (the City) built the West Chicago Sewage Treatment Plant in 1919. It accepted radioactive waste materials from the Kerr-McGee Rare Earths Facility. It used them as fill material, causing soil contamination. Contamination also entered the West Branch DuPage River. From 1986 to 1987, Kerr-McGee led cleanup activities to allow the City to expand the treatment plant. However, more investigations found more radioactive waste contamination. EPA added the site to the National Priorities List (NPL) in 1990. Cleanup at the treatment plant included removal and off-site disposal of contaminated soil and sediment. Cleanup of the river part of the site, including habitat restoration, took place from 2004 to 2008. After cleanup, EPA took the site off the NPL in 2013. The Forest Preserve District of DuPage County (the District) owns most of the land along the river portion of the site. EPA worked with the District to share technical expertise and guidance related to achieving restoration goals. The District also helped fund restoration activities at the site. Land use along the river portion of the site is primarily recreational. The ecological health and recreational use of the river increased after cleanup and restoration activities. A sewage treatment plant continues to operate on part of the site.

LASALLE ELECTRIC UTILITIES

The 10-acre LaSalle Electrical Utilities Superfund site is in LaSalle, Illinois. The LEU Company, an electrical equipment manufacturer, opened on-site before World War II. From about 1943 to 1982, the facility made capacitors for industrial applications and power transmission. From the late 1940s to 1978, operators used polychlorinated biphenyls (PCBs) in capacitor production. Reports allege the application of PCB-contaminated waste oil as a dust suppressant, both on-site and off-site, until 1969. Starting in 1975, government agencies, including EPA, Illinois EPA, and the Occupational Safety and Health Administration (OSHA), led inspections and issued complaints and orders to the LEU Company to address improper manufacturing and handling practices. In 1982, the company filed for bankruptcy. EPA added the site to the National Priorities List (NPL) in 1983. EPA took actions to secure the area, consolidating drummed waste and controlling off-site migration of surface water. Cleanup included removing PCB-contaminated soils from yards, road shoulders, farm fields and business areas, and treating the soil on-site. It also included demolition of the industrial complex, decontamination of structural steel for recycling, shipping of non-thermally destructible material off-site for disposal, thermal destruction of PCB-contaminated soil, building demolition debris and contaminated stream sediments, groundwater cleanup, and soil vapor extraction. EPA is working with Illinois EPA to reevaluate the remedy following the flooding of the groundwater treatment building in 2011. Continued uses around the site include residential and commercial areas.

MATTHIESSEN AND HEGELER ZINC COMPANY

The 227-acre Matthiessen and Hegeler Zinc Company Superfund site is in La Salle, Illinois. From 1858 to 1978, a zinc smelting and rolling facility was on-site. Facility operations contaminated soil at the site. La Salle Rolling Mills continued operating until the firm’s bankruptcy in 2001. Investigations by the Illinois Environmental Protection Agency in the 1990s found contamination in slag piles remaining from smelting activities. EPA added the site to the National Priorities List (NPL) in 2003. The site’s potentially responsible parties removed contaminated waste piles, asbestos and storage tanks. In 2009, EPA demolished a contaminated building. EPA selected the site’s long-term remedy in 2017. It includes digging up soil, backfilling these areas with clean soil, putting soil covers and revetments in place, revegetating areas, and constructing a consolidation cell. It also includes putting property access restrictions and institutional controls in place and using other measures to manage surface water runoff and control soil erosion. 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 site, the funding facilitated sampling and cleanup at residential properties with elevated levels of contamination. Funding will also be used to address contamination on industrial areas of the site. In 2023, EPA updated the remedy to include short-term groundwater monitoring and institutional controls to restrict groundwater use. Carus Chemical Company’s chemical manufacturing facility remains active on-site. A metal service center and wholesaler, Continental Metals, is now also on-site. A residential area surrounds the facility. A river runs along the eastern edge of the site.

OTTAWA RADIATION AREAS

The Ottawa Radiation Areas Superfund site is in LaSalle County, Illinois. It consists of 16 areas across the city of Ottawa. The Radium Dial Company (from 1918 to 1936) and Luminous Processes, Inc. (from 1937 to 1978) made glow-in-the-dark dials for clocks and watches on-site using radium-based paint. Fill material in the Ottawa area consisted of building demolition material and soil polluted with radioactive waste from the plants. EPA added the site to the National Priorities List (NPL) in 1992. Cleanup involved removing contaminated soils and putting in radon reduction systems. Institutional controls also ensure the long-term protection of human health. 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 funding will mostly be allocated towards the last of 16 contaminated areas, the landfill on NPL-8, where cleanup will include excavation and off-site disposal of contaminated soils, excavation backfilling, and revegetation of the area. The Illinois Power sub-area is now a skate park. Residential and recreational reuses are on-site. Other site uses include Illinois Appellate Court facilities, a private school and a hardware store.

OTTAWA TOWNSHIP FLAT GLASS SITE

The 228-acre Ottawa Township Flat Glass Site is in Naplate, Illinois. It includes parcels north and south of the Illinois River. A glass-manufacturing facility opened on-site in 1908. Until 1970, operators used arsenic trioxide in the manufacturing process to reduce product discoloration. Waste from this practice came from the grinding and polishing of plate glass into a slurry material that went into silica quarries and other disposal areas on-site. The waste streams generated as part of facility operations contaminated soil, groundwater and Illinois River sediment. In 1999, Illinois EPA referred the site to EPA. An agreement between the responsible party and EPA in 2001 addressed the area using the Superfund Alternative Approach (SAA) rather than listing the site on the National Priorities List (NPL) for cleanup. Cleanup actions include removal of contaminated soil and slurry material from residential properties and disposal in an approved off-site landfill. Warning signs at the perimeter fence and along a designated stretch of the Illinois River help prevent recreation and trespassing exposures to contaminated river sediment. Some homes with contaminated wells connected to the public water supply. Stormwater drainage improvement modifications were made to the former wastewater quarries. Investigations for the site’s final groundwater remedy are ongoing. An active float-glass facility remains adjacent to the site. The site is also part of a larger area that is critical habitat for the Indiana bat.

OUTBOARD MARINE CORP.

The 100-acre Outboard Marine Corp. Superfund site is on the western shore of Lake Michigan in Waukegan, Illinois. To manage investigations and cleanup, EPA divided the site into operable units (OUs). OU1 is an area of Waukegan Harbor. OU2 is the former location of a railroad tie treatment plant in the early 1900s. This area later became a manufactured gas and coke facility. Outboard Marine Corporation bought the OU2 property in the 1970s. It demolished the coke plant buildings. OU3 is a containment area for contaminated materials removed during a harbor cleanup from 1990 to 1993. OU4 is an abandoned facility. Outboard Marine Corporation made parts for outboard motors there from about 1949 until the company declared bankruptcy in 2000. This abandoned facility is the source of polychlorinated biphenyls (PCBs) and TCE in the harbor. EPA added the site to the National Priorities List (NPL) in 1983. Cleanup included dredging contaminated sediments, removing contaminated soils and placing a cap over contaminated materials. It also included active groundwater treatment at OU2 from 2008 to 2012 and at OU4 starting in 2011. The site’s long-term cleanup and monitoring of groundwater and harbor fish is ongoing. Institutional controls limit fish consumption and use of the site and groundwater and protect the remedy from disturbance. Parts of the site remain in continued use. A recreational boat storage and repair business operates at the harbor. Other industrial support businesses are also in the harbor area. The Waukegan Port District runs a recreational and commercial marina at the harbor. It supports commercial and recreational fishing and boating access to Lake Michigan. Some beachfront areas of the site include ecologically important emergent dune-land environments. These areas provide critical habitat for the piping plover, a federally protected endangered species, and support several state-protected plant species. In 2015, EPA developed a reuse assessment for areas along the Waukegan lakefront, including the site, to support reuse planning. The city of Waukegan (the City) also finalized a master plan for the redevelopment of the lakefront area. The City bought the OU2 area, added clean fill and rezoned the property for high-density residential development, in accordance with the master plan. City plans call for parkland and mixed-use areas on the OU3 and OU4 parts of the site.

SOUTHEAST ROCKFORD GROUND WATER CONTAMINATION

The Southeast Rockford Ground Water Contamination Superfund site covers about 7.5 square miles in Rockford, Illinois, next to the Rock River. There are several contaminated groundwater plumes in this area. Investigations by Illinois EPA from 1981 to 1988 found volatile organic compound (VOC) contamination in private and municipal wells. The contaminants came from storage tanks and improper disposal practices at local industries. EPA added the site to the National Priorities List (NPL) in 1989. To manage investigations and cleanup, EPA divided the site into three areas, or operable units (OUs). From 1989 to 1991, EPA and the city of Rockford addressed the drinking water contamination at OU-1 by temporarily providing bottled water to homes, connecting 547 properties to the public water supply and installing granulated activated carbon filtration on a municipal well. At OU-2, EPA connected 277 more properties to the public water supply. Long-term groundwater monitoring is ongoing. Overall, 824 homes connected to the city of Rockford's municipal water system. EPA identified four source areas as the main contributors to the groundwater VOC plumes. These areas are OU-3. These source areas use active treatment remediation to address the source materials. In 2020, the cleanup requirements in Source Area 4 were met, resulting in a partial site deletion from the NPL. The area is available for unrestricted use and unlimited exposure. In December 2021, Source Area 7 was among those areas selected by EPA to receive cleanup funding for continuing groundwater treatment under the Bipartisan Infrastructure Law (BIL). Both Source Area 7 and Source Area 9/10 have decreasing VOC concentrations in groundwater. In 2024, a pilot study is planned for Source Area 11 to select a remedy that will address source contamination. EPA also studied the nearby Rock River in 2018 to see if wildlife is harmed by the discharge of contaminated groundwater into the river. Studies found no impacts on wildlife were expected. Vapor Intrusion studies took place across the site in 2014 and 2017. They found no exposures due to incomplete vapor intrusion pathways. Current site uses include residential areas and a variety of businesses. They include an auto-parts store, a car stereo store, a storage facility, an engineering company for aerospace and defense industries, a lab equipment supplier, a military base, and a steel sheet and plate product manufacturer.

The 66-acre Tri-County Landfill Co./Waste Management of Illinois, Inc. Superfund site is in Elgin, Kane County, Illinois. Two landfills received commercial and industrial waste on-site from the 1960s to 1976. The landfills accepted municipal, commercial and industrial wastes. Landfill operations contaminated groundwater, surface water, sediment in a nearby wetland, and surface soil at the landfills. The landfills were closed under court order in 1981. Investigations took place from 1983 to 1992. EPA added the site to the National Priorities List (NPL) in 1989. Cleanup from 1999 to 2001 included digging up and capping contaminated soils, collecting and treating landfill gas, monitoring and treating contaminated groundwater, and restricting land and groundwater use. Due to low levels of contamination in groundwater, EPA deferred active treatment in 1996 to see if landfill gas removal and the cap stopped further contamination of groundwater. Active treatment could be required in the future if groundwater contamination increases. Institutional controls limit site and groundwater use and protect the remedy from disturbance. Groundwater monitoring and operation and maintenance activities are ongoing. Part of the site is in use for vehicle storage.
