The Elizabethtown Landfill is an unlined, inactive landfill that occupies approximately 16 acres in West Donegal Township, Lancaster County, roughly one mile southwest of Elizabethtown, Pennsylvania. The Elizabeth Landfill site includes the Elizabethtown Landfill and all areas adjacent to or affected by the landfill where hazardous substances from the landfill have come to be located.
The landfill property is bounded on the south, southeast, and southwest by private residences located on west Ridge Road and Valerie Drive. Adjoining the landfill property to the west and northeast are agricultural lands. Private residences located on West Bainbridge Road adjoin the landfill property to the northwest. Residential properties adjacent to the landfill obtain water from private wells. Four homes on West Bainbridge Road and one home on Rear Maytown Road are currently supplied bottled water by the owner of the landfill. The Masonic Homes properties, located northwest and north of the landfill, obtain water from public water supply wells which it owns and operates on its property. Residents living closer to the Borough of Elizabethtown obtain potable water from a municipal supply system upgradient of the site.
For some years prior to 1959, a sandstone quarry was operated at the site of the Elizabethtown Landfill. It was subsequently operated as an unlicensed landfill from at least 1959 through 1973, accepting municipal, household, and industrial wastes, in its later years operating under the name of United Disposal, Inc. (UDI). UDI ceased landfilling operations on or about July 31, 1973 pursuant to a consent decree with the Pennsylvania Department of Environmental Resources (PADER) (subsequently renamed the Pennsylvania Department of Environmental Protection (PADEP)). In March 1976, UDI sold its assets, including the landfill, to SCA Services, Inc. (SCA). SCA operated the site as a trash hauling transfer station; it also parked and maintained trash hauling trucks and occupied an office building, at the facility. In 1986 and 1987, SCA installed a soil-based cover over approximately 12 acres comprising the northern portion of the landfill; the approximate four remaining acres are covered by a permeable base of gravel. In 1994, Waste Management Disposal Services of Pennsylvania, Inc. (from which SCA changed its name in 1993), stopped using the facility as a transfer station, and since that time the site has been inactive.
The Environmental Protection Agency (EPA) added the site to the Superfund National Priorities List (NPL) in March 1989 due to the presence of site-related contaminants in the drinking water aquifer that extends underneath the landfill, and in a stream near the landfill. In September, 1990 SCA entered into an administrative order on consent with EPA to conduct a remedial investigation/feasibility study (RI/FS) to determine the extent of contamination at the site. A Record of Decision (ROD) was completed in October 1997.
The remedy includes: capping the uncapped (southern) portion of the landfill; upgrading of storm water controls in both the northern and southern landfill areas; conducting a predesign study of the groundwater and surface water to evaluate the effectiveness of the remedial measures on the attainment of groundwater and surface water cleanup levels, and to furnish data necessary to determine appropriate locations for a groundwater extraction well(s). Construction of a groundwater extraction well system; extraction and on-site treatment of contaminated groundwater and leachate; and discharge to Conoy Creek. The groundwater treatment system includes chemical precipitation of metals, air stripping of volatile organics with emissions control using vapor phase carbon, and liquid phase carbon adsorption of semi-volatiles, pesticides, and miscellaneous contaminants. If after the landfill cap is installed the predesign groundwater and surface water study demonstrates that the ground water and surface water cleanup levels can be attained within a reasonable time period without extraction and treatment of groundwater, then the Environmental Protection Agency (EPA) will modify the Record of Decision (ROD) to eliminate the requirement for such extraction and treatment.
The selected remedy also includes the extension of the security fence to surround the entire landfill, and establishment of deed restrictions to minimize the potential for direct contact with landfill contents, and prohibit use of the water supply well located at the landfill for the provision of drinking water. Groundwater, surface water, sediment, and wetlands monitoring will be conducted, and landfill gas and leachate management systems will be installed in the southern portion of the landfill. Quarterly monitoring of five nearby residential wells and two public water supply wells will also be conducted.
