68th Street Dump/Industrial Enterprises
The 239-acre 68th Street Dump/Industrial Enterprises Superfund site is in Baltimore County, Maryland. From 1950 to 1970, landfills on site accepted industrial and commercial wastes containing hazardous wastes, which contaminated soil, sediment, groundwater, surface water and wetland areas. EPA assessed the site under the Superfund Alternative Site (SAS) process. In 1980, the Maryland Department of the Environment (MDE) led several emergency cleanup actions. They included the removal of more than 50 55-gallon drums of assorted waste. EPA led more investigations and selected a cleanup plan in 2013. It includes placing a soil cap over contaminated areas, removing contaminated soil hotspots, other debris and pond sediment, treating groundwater, restoring stream banks, and revegetating capped landfills with native plants. A 2017 Consent Decree between EPA and more than 40 responsible parties guides remaining cleanup activities. EPA approved the parties’ Remedial Design in March 2023, and the Remedial Action began in June 2023. RA is anticipated to be complete in 2026. Current site features include a highway overpass, wetlands and streams.

Bear Creek Sediments
The Bear Creek Sediments Superfund site is in Sparrows Point, Maryland. It is next to the Sparrows Point peninsula, which was the site of steelmaking and ship-building industries for over 100 years. The Bethlehem Steel Corporation (BSC) was the primary owner and operator for much of Sparrows Point’s operational history from 1887 to 2013. Hazardous substances from the steelmaking process and from wastewater and stormwater discharges migrated into Bear Creek and contaminated creek sediments. EPA added the site to the National Priorities List (NPL) in 2022. Land sources of contamination are being addressed by the current owner of the facility with Maryland Department of the Environment and EPA oversight under other cleanup programs. They are not included as part of the site. An investigation is underway to verify the nature and extent of offshore contamination prior to cleanup.

Chemical Metals Industries, Inc.
The Chemical Metals Industries, Inc. Superfund site is in Baltimore, Maryland. It includes two separate properties. Chemical Metals Industries (CMI) ran a chemical manufacturing facility and recovered precious metals at one property. CMI used the other property, a closed gas station, to store waste and scrap metal. Leaking drums on both properties prompted inspections. Investigators found extensive contamination and the potential for fires or explosions. EPA proposed adding the site to the National Priorities List (NPL) in 1981. EPA did not finalize the listing because its early cleanup actions addressed the threats. With support from the Maryland Department of the Environment, EPA removed contaminated drums, debris, and liquid waste from the site, and capped the area to prevent further exposure to contamination. After more investigations by EPA in 1998 found the cap was deteriorating, EPA removed contaminated soil and replaced the cap. The Maryland Department of the Environment now has a storage and equipment maintenance facility on one of the site properties.

Kane & Lombard Street Drums
The Kane & Lombard Street Drums Superfund site consists of two Operable Units. Operable Unit 1 (OU1) is a 10-acre parcel located at the corner of Kane and Lombard streets in Baltimore, Maryland. For more than 22 years, an open dump for demolition, municipal and industrial wastes was on site. Disposal activities resulted in the contamination of soil and groundwater. EPA added the site to the National Priorities List (NPL) in 1986. EPA worked closely with the community, the Maryland Department of the Environment, and a private investment group on a cleanup compatible with redevelopment. EPA removed waste drums, put in a subsurface barrier to prevent further contamination of groundwater at OU1, and capped contaminated soil. EPA also restricted land and groundwater use to prevent exposure to contamination. Today, OU1 uses include a golf driving range and several commercial and industrial businesses. Operable Unit 2 of the Kane and Lombard site is a 40-acre parcel with several commercial businesses located on it. Contaminated soil and groundwater at OU2 is being addressed under a separate EPA action. Groundwater from the site is not a source of drinking water.

Mid-Atlantic Wood Preservers, Inc.
The 3-acre Mid-Atlantic Wood Preservers, Inc. Superfund site is in Harmans, Maryland. A wood-treating facility was on site from 1974 to 1993. In 1978, investigations found soil and groundwater contaminated with chemicals from facility operations. EPA added the site to the National Priorities List (NPL) in 1986. In 1993, the site’s potentially responsible party led cleanup activities with EPA oversight. Cleanup included removing contaminated soil from a neighboring property and covering the entire 3-acre facility with an asphalt cap. In 1994, EPA entered into a Prospective Purchaser Agreement (PPA) with Gunther’s Leasing & Transport, a neighboring property owner. The PPA enabled the company to expand its operations and use part of the site as a parking lot and for office space. Local Machine Service, Inc. leases the former treatment building on site and runs a recreational boat repair shop. Site owners store large vehicles on site. EPA took the site off the NPL in 2000.

Ordnance Products, Inc.
The 95-acre Ordnance Products, Inc. Superfund site is in the town of North East, Maryland. From 1960 to 1972, a manufacturing plant produced ordnance products such as grenade fuses and detonators on site. Operators buried burned waste in open pits and discharged waste into five unlined surface locations. These practices resulted in contamination of groundwater, soil, sediment and sludge. Sampling also found site-related contamination in nearby residential drinking water wells. EPA added the site to the National Priorities List in 1997. Cleanup included removal of hazardous materials and contaminated soil. It also included treatment systems for affected residential groundwater wells to provide homes with safe drinking water. In 2012, EPA added systems to remove contaminated air from two houses. EPA finished construction of the groundwater cleanup in June 2015. Residential areas adjacent to the site remain in continued use. In December 2021, the site was among those selected by EPA to receive cleanup funding under the Bipartisan Infrastructure Law (BIL) to accelerate the cleanup of the remaining contamination. With this funding, EPA is already initiating work on backlogged remedial construction projects and accelerating cleanups at NPL sites.

Southern Maryland Wood Treating
The Southern Maryland Wood Treating Superfund site is in Hollywood, Maryland. Wetlands cover most of the 94-acre area. From 1965 to 1978, wood-treating operations took place on 25 acres of the site. These activities resulted in contamination of soil, groundwater, and a stream next to the site. In the early 1980s, the owners abandoned the property, leaving processing equipment and deteriorating containers of chemicals behind. EPA added the site to the National Priorities List (NPL) in 1986. To clean up the site, EPA removed contaminated soil and sediment and heat-treated the material to remove hazardous substances. In 2000 and 2001, EPA regraded the site and planted wildflowers and grains to restore wildlife habitat. In a 2004 Ready for Reuse Determination, EPA documented that the site’s remedy allows for unrestricted future use. EPA took the area off the NPL in 2005.

Woodlawn County Landfill
The 38-acre Woodlawn County Landfill Superfund site is in Cecil County, Maryland. A sand-and-gravel quarry was on site. Cecil County then ran a municipal landfill on site from 1960 to 1978. From 1978 to 1981, operators disposed of polyvinyl chloride industrial sludge at the site. Landfill operations contaminated soil, groundwater, and stream sediments. EPA added the site to the National Priorities List (NPL) in 1987. With EPA oversight, the site’s potentially responsible parties (PRPs) cleaned up the site. Cleanup included the placement of a vegetative soil cover over the waste. It also included monitoring the natural breakdown of groundwater contaminants. Cleanup finished in 2001. Long-term maintenance and monitoring activities are ongoing. The PRPs put in the vegetative soil cover to support wildlife habitat. Together with an adjacent 58-acre area, the site is part of an environmental education center. Local schools, the Boy Scouts of America and Girl Scouts of America, and the community visit the site for nature and science projects, environmental education and recreation. Cecil County also runs a solid waste transfer station on part of the site. It provides local residents with drop-off facilities for trash, recycling and yard waste.
