The Solvent Savers Superfund site covers 13 acres in the Town of Lincklaen. Industrial solvents and other wastes were brought to Solvent Savers Inc., a chemical waste recovery facility, for reprocessing or disposal from about 1967 to 1974. Operations included distillation to recover solvents for reuse, drum reconditioning, and burial of liquids, solids, sludges, and drums in several on-site areas. The quantities and types of wastes disposed at the site and their locations are not fully known. The closest residence is located approximately 1,250 feet south of the site. Public water supplies do not exist in the general area; therefore, the residents rely on private wells. The Town of Lincklaen has a population of approximately 500 people. Fifteen dairy farms are located in the town. Pastures for dairy cows are located two miles from the site along a portion of Mud Creek, which is downstream of the site. Mud Creek is classified as a trout stream by the state and is used for recreational activities and livestock watering. In addition, alfalfa, corn and other crops for human and livestock consumption are grown in the area.
The ground water, surface water, sediments, and soil are contaminated with volatile organic compounds (VOCs) which include, primarily, tetrachloroethene, trichloroethylene, and 1,1,1-trichloroethane. The soil and ground water contain inorganics, including arsenic, barium, cadmium, chromium, and lead. The soil is also contaminated with polychlorinated biphenyls (PCBs).
Based on environmental findings by the New York State Department of Environmental Conservation and a subsequent investigation by the EPA, the site was placed on the National Priorities List of uncontrolled hazardous waste sites in 1983. EPA took short-term cleanup actions to address immediate risks posed by the site and developed a detailed plan for the more complex long-term cleanup of the site. The excavation and off-site disposal of 160 drums and drum parts and approximately 200 cubic yards of contaminated soil have significantly reduced the threats associated with further migration of hazardous materials and contamination of the soil and ground water.
Once the immediate risks were addressed, soil vapor extraction treatment was used to reduce the VOCs within the soil. This method removes the VOCs from the soil in the form of vapor by applying a vacuum. The volume of soil that was contaminated with VOCs was successfully removed from approximately 135,000 cubic yards to approximately 8,200 cubic yards. The remaining VOCs are located in two "hot spot" areas that are also contaminated with PCBs. In addition, soil in other areas of the site is contaminated with PCBs.
The soil cleanup work began in September 2012. The design of the soil cleanup was prepared by contractors on behalf of the companies responsible for the cleanup; the EPA is overseeing the cleanup, which will be performed in two phases. The soil that is contaminated with VOCs and PCBs will be excavated and disposed of off-site at EPA-approved facilities. Excavated soil that has high levels of PCBs will be stabilized by introducing an agent similar to cement to bind the contaminants before it is disposed of off-site. All excavated areas will be backfilled with clean fill and re-planted with vegetation. During the cleanup, approximately 15,000 cubic yards of contaminated soil will be excavated and properly disposed of off-site. It's estimated that the construction work will be completed in about 13 months.
The design for the ground water cleanup is currently underway and is expected to begin in 2015.
