**Niagara Sanitation Company: Superfund Site Project Update - See Digital Files for new site documents.

New York State Department of Environmental Conservation (DEC) is continuing investigation of the Niagara Sanitation Company site ("site") located at Nash Road, Wheatfield, Niagara County. Please see the map for the site location. Documents related to the cleanup of this site can be found at the locations identified below under "Where to Find Information."

In an effort to keep the Public updated on the current phases of the clean-up work, DEC will be periodically updating this website.

Summary of the Site Characterization Investigations

In 2013, DEC conducted a follow-up Site Characterization Study to determine if the site posed a significant threat to either public health and/or the environment and to confirm the extent of the Love Canal site wastes reportedly disposed of at the site. The results of this investigation clearly identified the disposal location of the Canal waste materials. The study showed elevated levels of: 4,4'-DDD, 4-4'-DDT, Aldrin, alpha BHC, beta-BHC, gamma-BHC (Lindane), Toluene, Cyclohexane, Dichlorobenzene, Chlorobenzene, and Benzene. While these contaminants were detected in subsurface soils within the Site's Love Canal waste disposal area, there was little impact of these wastes detected beyond that area with the exception of trace levels of BHCs in surface water that is ponding overtop of the wastes. There was no groundwater contamination noted beyond the property boundaries.

Project Background

Location: The Niagara Sanitation Company Site, also known as the Nash Road Landfill is an inactive landfill located directly north of City of North Tonawanda, adjacent to Nash Road, in the Town of Wheatfield, Niagara County, New York.

Site Features: The site is mostly surrounded by suburban residential development. The site was a swampy area before landfill activities occurred. Since landfilling, portions of the property are covered with surface water at certain times of the year, particularly in the spring. The site is bordered to the north by Holy Infant Church, to the east by a cemetery, to the south by a right of way and a residential area, and to the west by Nash Road and houses. Landfilling of wastes and excavation of a disposal trench has resulted in irregular ground surface topography. Relief on-site is less than 10 feet.

Current Zoning/Use(s): The site is zoned R-1 (Residential). To the west of the site it is also zoned R-1, while north and east of the site it is zoned C-1 (Commercial). The southern border of the site follows the boundary of the City of North Tonawanda and is zoned residential. Access to the site is not restricted. The entire site is overgrown with mature trees and brush. The current owner of the site is the Town of Wheatfield.

Past Use(s): The Niagara Sanitation Company Site was operated as a landfill by Niagara Sanitation Company between 1964 and 1968. Both municipal and industrial solid wastes, including caustic materials and sludges, are disposed at the site. Records show that the site was used for disposal by the Niagara Falls Air Force Base, Bell Aerospace, Carborundum, Frontier Chemical, Graphite Specialties, Continental Can, and Grief Brothers. Records also indicate that approximately 1600 cubic yards of Love Canal waste was disposed in a trench at this site by the DOT between June 6, 1968 and July 15, 1968 during construction of the LaSalle Expressway. The disposal trench was reportedly 100 feet by 30 feet by 27 feet deep and is believed to be located partially beneath ponded areas on the site. The debris was placed in the bottom 15 feet of the trench and 12 feet of clean fill was placed on top as a cover.

DEC conducted two Phase II studies at the site in 1985 and 1989. The results of these investigations confirmed the location of the Love Canal wastes. They also documented that the wastes did not pose a significant threat and the site remained as a Class 3 designation. In 2013, DEC conducted a follow-up Site Characterization Study to reconfirm that the site did not poses a significant threat to either public health and/or the environment and to confirm and delineate the extent of the Love Canal wastes reportedly disposed of at the site. A report on the finding was completed in late 2013 confirming the findings of the two previous studies and defining the location of the Love Canal waste disposal area. The study also determined that further investigation was warranted in the west end of the Landfill. In 2014 DEC conducted the recommended follow-up investigation and characterized the municipal and industrial fill in the remainder of the landfill. While the majority of the site contained contaminant levels typical of urban wastes, three areas were identified with elevated levels of lead and PCBs. No off-site migration of contamination was noted in either study.

Site Geology and Hydrogeology: The site geology consists of fill or topsoil mixed with soil at the surface; glacial/lacustrine deposits which include an upper sand lens; brown/gray silty clay gray/red clay; and a lower sand lens; glacial till and then Dolostone bedrock. Bedrock beneath the site is occurring at depths varying from 65 feet to 71 feet below the ground surface. Sawyer Creek, which flows within 1000 feet of the northeast corner of the site flows into Bull Creek about 1.1 miles southeast of the site, which subsequently flows into Tonawanda Creek then into the Niagara River. The aquifer of concern occurs within the layers of sand interbedded with the clay soil approximately 60 feet beneath the site. The depth to water above the lower clay unit at the site is between 3 and 20 feet below the ground surface. Shallow groundwater most likely moves northeastward toward Sawyer Creek.

Next Steps

The information collected during the investigation will be summarized in a report. After the site investigation has been completed, DEC will conduct a "Feasibility Study". This study uses information obtained during the site investigation to develop and evaluate potential ways to address contamination related to the site.

DEC will then develop a draft remediation plan, called a "Proposed Remedial Action Plan". This plan describes the alternatives evaluated and the remedy preferred by DEC. The draft remediation plan explains the decision that led to the preferred remedy by discussing each alternative and the reasons for choosing or rejecting it. The goal of the plan will be to ensure the protection of public health and the environment. DEC will announce the draft remediation plan in a future fact sheet, and will present it to the public for its review and comment during a 30-day comment period and at a public meeting.

Additional site details, including environmental and health assessment summaries, are available on DEC's website.

State Superfund Program

New York's State Superfund Program (SSF) identifies and characterizes suspected inactive hazardous waste disposal sites. Sites that pose a significant threat to public health and/or the environment go through a process of investigation, evaluation, cleanup and monitoring. DEC attempts to identify parties responsible for site contamination and require cleanup before committing State funds.
