The Eighteenmile Creek Superfund Site (Site) is located in Niagara County, New York, on the south side of Lake Ontario. On June 30, 2011, the New York State Department of Environmental Conservation (NYSDEC) referred the site to the EPA for inclusion on the federal National Priorities List (NPL) of hazardous waste sites. The NYSDEC based its referral on studies of several properties in Lockport, New York and of the sediment in Eighteenmile Creek. U.S. Environmental Protection Agency (EPA) included the site on the NPL on March 15, 2012.
A remedial investigation (RI) report summarizing the results of sediment investigations performed at the Eighteenmile Creek Area of Concern (AOC) was prepared for the EPA’s Great Lakes National Program Office (GLNPO) under the Great Lakes Legacy Act (GLLA) program. The investigation area includes Olcott Harbor (mouth of the creek) and extends upstream through the city of Lockport to the Erie Canal. The RI included compilation of a comprehensive database of over 750 sediment samples from the GLLA sediment characterization of the creek and historical data provided by the Niagara County Soil and Water Conservation District (NCSWCD), the NYSDEC, the United States Army Corps of Engineers (USACE), and EPA Region 2. An evaluation of the nature and extent of contamination in sediments throughout the investigation area will be presented along with a summary of the RI findings.
