I I mi AIAI o A Kir> EPA REGION 2 LUDLOW SAND congressional dist. 23 _ _ _ Oneida County & GRAVEL — NEW YORK EPA ID# NYD013468939 Site Description The 18-acre Ludlow Sand & Gravel site is a landfill and gravel pit located on a 130-acre parcel of land. Disposal at the site began in the early 1960s and included domestic wastes, septic tank effluent, industrial wastes such as dyes and waste oils, and animal parts from a meat processing plant. Area residents expressed concern in 1966 when large areas of the site were left uncovered and a strong odor could be detected at a considerable distance. In 1982, trace quantities of poly chlorinated biphenyls (PCBs) were detected in the leachate pools located at the southern portions of the property. The District Court of Binghamton ordered the landfill closed and dumping ceased in 1988, although the gravel pit was still in operation. A New York State-designated wetland is located to the southeast of the site. The landfill is in a groundwater recharge zone to an aquifer along Sauquoit Creek, which serves as a major discharge point for groundwater flowing from this aquifer and is a tributary of the Mohawk River. The residents east of the landfill obtain their drinking water supply from the aquifer. The municipal water supply for the community of Clayville is obtained from ground water. The nearest residence is 1/2 mile from the landfill. Three residential wells are located within 1,000 feet of the site, and eight additional wells are 1,000 to 3,000 feet away. Site Responsibility: This site is being addressed through Federal, State, and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 12/01/82 Final Date: 09/01/83 LUDLOW SAND & GRAVEL 1 March 2002 ------- Threats and Contaminants The groundwater and landfill wastes are contaminated with volatile organic compounds (VOCs), heavy metals including chromium and nickel, PCBs, and phenols. Sediments contain VOCs and PCBs. The soil and surface water were contaminated with PCBs. Leachate pools contained PCBs and phenols. Residents near the site rely on private wells for drinking water. Although these wells are not contaminated, there was a possibility that chemicals migrating from the landfill could pollute them. Sediment from the wetlands was contaminated. There was a potential for people who accidentally ingest the sediments to suffer adverse health effects. ZE Cleanup Approach This site is being addressed in two long-term remedial phases focusing on source control and the cleanup of groundwater, surface water, and soils from adjacent areas. Response Action Status Source Control: In 1988, the EPA selected a remedy to contain the source of the contamination by: (1) consolidating approximately 10,000 cubic yards of contaminated soil and sediment adjacent to the landfill and disposing of it in the landfill and then placing either a clay or synthetic cover over it to prevent rain water from coming into contact with the buried materials; (2) collecting the leachate from seepage areas; (3) dewatering the landfill, if necessary, by using either a passive drain system or using groundwater extraction wells; (4) lowering the water table to prevent groundwater from coming into contact with the waste material; (5) treating the contaminated leachate and groundwater at an on-site facility, or if the volume of water is small, transporting the water and leachate to an approved federal facility; (6) fencing the site, including the wetlands; (7) controlling future use of the property by deed restrictions; and (8) monitoring the ground water, private wells, and surface water to ensure the cleanup has been effective. The cleanup was conducted by the potentially responsible parties pursuant to a Consent Decree with the State of New York. A plan was approved by the State in 1990 for the cleanup of the landfill and the wetlands. The cleanup was completed in 1991 and 1992. A report documenting the cleanup efforts was submitted by the PRPs in 1995. n LUDLOW SAND & GRAVEL 2 March 2002 ------- r>^ Ground Water, Surface Water, and Soils from Adjacent Areas: Data has been collected on the nature and extent of off-site contamination. However, additional data needed to be collected for ground water and surface water in the vicinity of the landfill, as well as soils from an adjacent gravel pit. This investigatory study, which is being conducted by the potentially responsible parties with oversight by the State, is underway. The report to evaluate different options for the cleanup of the off-site contamination is being reviewed by the State and EPA. The study is scheduled for completion by summer 2002 when a remedy for the gravel pit will be selected by the EPA. Cleanup Progress After adding this site to the NPL, the EPA performed preliminary investigations and determined that no immediate actions were required at the Ludlow Sand & Gravel site while further investigatory studies were being completed and cleanup activities were started. Over 40,000 cubic yards (1,022,200 tons) of contaminated soils and approximately 15,000 cubic yards (24,000 tons) of sediments have been excavated from the adjacent wetlands and gravel pit and consolidated in the landfill; the leachate collected from the seepage areas; a drainage system installed and operated to dewater the landfill; and a final cap placed over the landfill. The collected water is being treated using a system built on the site. These actions have removed the potential for contact of the water with the contaminants and therefore, have prevented further migration of contamination from the landfill into the environment. Additional contaminated soils remain at the gravel pit and will be addressed following completion of the investigatory study on the soils, ground water and surface water of the adjacent areas and selection of the remedy.
