The Sidney Landfill site is located on Richardson Hill Road approximately 10 miles southeast of Sidney, New York. In March 1989, the site was added to the National Priorities List (NPL) based on investigations completed by the New York State Department of Environmental Conservation (NYSDEC) and the New York State Department of Health (NYSDOH). The Richardson Hill Road Landfill (RHRL) site, which is also on the NPL, is located immediately south of the Sidney Landfill site. Historical waste disposal resulted in polychlorinated biphenyl (PCB) and volatile organic compound (VOC) contamination of soil and groundwater at the Sidney Landfill site and of soil, groundwater, and sediments at the RHRL site. Soil and sediment remedies have been implemented and completed at both sites.
