Hoosick Falls Area

Information for Communities Impacted by Per- and Poly-fluorinated Aklyl Substances (PFAS)

village of Hoosick Falls
The Village of Hoosick Falls is the site
of groundwater PFAS contamination linked
to past manufacturing sites in the area.

DEC works closely with New York State Department of Health (DOH) to ensure the safety and health of all New Yorkers. Through the work of the Governor's Water Quality Rapid Response Team, New York State has taken unprecedented action and spared no expense to secure clean drinking water for the Hoosick area. For the latest community information and updates, please visit the DOH website.

In 2016, Perfluorooctanoic acid (PFOA) was detected in the Village of Hoosick Falls' public drinking water supply and Town of Hoosick private drinking water wells above the federal Environmental Protection Agency (EPA) health advisory level of 70 parts per trillion (ppt). The presence of PFOA in groundwater is linked to past manufacturing sites in the Hoosick area. PFOA is part of a group of compounds called Per- and Poly-fluorinated Aklyl Substances (PFAS).

Learn more about PFAS and how these issues have been addressed.

Community Participation Work Group

DEC and DOH have announced plans to establish a Hoosick Area Community Participation Work Group. Made up of area residents and state agency representatives, the Work Group will provide a forum for the greater Hoosick area community to discuss the progress of the PFOA cleanup and options for municipal water supply. It will also give directly impacted residents an avenue to request and provide information, opinions and perspectives on the projects.

DEC and DOH welcome your thoughts on the Work Group proposal (PDF). Email your comments to HFComments@dec.ny.gov by Friday, October 26, 2018.

Technical Assistance Needs Assessment

The proposal for the Community Participation Work Group was developed as a result of the recommendations from the Technical Assistance Needs Assessment (TANA)(PDF, leaves DEC website) performed by the Environmental Protection Agency. The TANA was performed in order to identify whether the community of Hoosick will require additional support to understand technical information and enable meaningful community involvement in the Superfund decision-making process.

The site is undergoing a remedial investigation. Work to date has included collection of samples from soil, groundwater and surface water. The main contaminant of concern (COC) is perfluorooctonic acid (PFOA) in soil and groundwater.

As part of the consent order with Saint-Gobain and Honeywell, DEC subsequently negotiated for to:

  • install and pay for operation and maintenance of a full capacity carbon filtration system for the Village water supply;
  • implement a remedial program for the Saint-Gobain McCaffrey Street sites; and
  • conduct investigations of three other sites in the Village and Town to determine if these sites should be listed as State Superfund sites

DEC has entered into a consent order with Honeywell (PDF) for implementation of investigations of the Oak Materials (River Road) Site (No. 442008) and the Former Oak Material (John Street) Site (No. 442049) in order to determine if either of these sites should be listed as a State Superfund site. In July 2017, the John Street site was listed as a Class 2 site and the existing consent order includes provisions for Honeywell to implement the remedial program at the site.

Oak Materials River Road Information

The Oak Material River Road site is a potential hazardous waste disposal site (P-site) and is in the site characterization phase of investigation. Upon completion of the site characterization, the DEC and DOH will determine the need for a remedial investigation and feasibility study. Work to date has included soil, groundwater, surface water and sediment sampling. Perfluoroctonic acid (PFOA) and Vinyl Chloride have been identified as contaminants of concern (COCs). Upon completion of the site characterization a determination of need to perform a remedial investigation will be made by DEC and DOH.

Former Oak Materials John Street Information

In July 2017, the Former Oak Materials John Street site was listed on the NYS Registry of Hazardous Waste Disposal Sites as a Class 2 site and the existing consent order includes provisions for Honeywell to implement the remedial program at the site. Advanced remedial investigation tasks are underway. Work to date at John Street has included collection of soil, groundwater, and soil gas/indoor air samples. Trichloroethene (TCE) and other chlorinated volatile organic chemicals (CVOCs) along with perflorooctonic acid (PFOA) are the primary contaminants of concern.

Hoosick Falls Landfill, Mechanic Street and First Street Sites

Hoosick Falls Landfill

The Hoosick Falls Landfill is a potential hazardous waste disposal site (P-site) and is in the site characterization phase of investigation. Upon completion of the site characterization, the DEC and DOH will determine the need for a remedial investigation and feasibility study. The main contaminant of concern is perfluorooctonic acid (PFOA), perfluorooctanesulfonic acid (PFOS) was also detected on the property.

Other Environmental Sampling in the Hoosick Area

Supplemental Groundwater Source Investigation

Saint-Gobain Performance Plastics and Honeywell (the Companies) are moving forward with a Supplemental Groundwater Source Investigation Program as a part of the ongoing Municipal Water Supply Study (Study) for the Village of Hoosick Falls (Village) under the terms of their existing Consent Order with DEC. The current exploration drilling and sampling work to characterize and assess the thickness and the water-bearing potential within targeted areas of the Hoosick River Valley Aquifer is discussed in detail in the approved 2018 Supplemental Groundwater Source Investigation Work Plan (PDF, 5.7MB) (CHA & ERM, July 2018). The initial phase of geophysical exploration work was completed during the week of July 30, 2018, and the drilling program started on September 4, 2018. This work is a component of the New Groundwater Source Option being considered and assessed as a viable drinking water source for the Village in the Study. Other water resources and options being evaluated in the Study include a New Surface Water Source, Connection to another Municipal Water System, Modification of the Existing Municipal System, Continued Use of the Existing Municipal System, Remediation of the PFAS Source, and Any Combination of these Resources/Options. Completion of this supplemental investigation work is expected by April 2019.

Potential PFAS Dump Sites Investigation

DEC has received information indicating that dumping has potentially occurred on specific properties in the Town of Hoosick, and in southern Washington County. The chemicals which are allegedly disposed of are potentially related to manufacturing of products containing PTFE, PFOA, or PFOS. The timeline of potential dumping varies according to the different reports, but generally is thought to have occurred during the 1970s, 1980s and 1990s. Production of PTFE materials began in the Town of Hoosick as early at 1955.

DEC has reviewed the list of tips which have been received and in 2018 will pursue the collection of data at sites located throughout the town of Hoosick, The Village of Hoosick Falls, and in southern Washington County. This work will determine if the sites contain elevated levels of contaminants and require further site characterization.

Environmental Sampling

In 2016, DEC conducted environmental sampling of soil, groundwater, surface water, and sediment in the Hoosick area to determine if these environmental media have been impacted by PFCs. This has helped determine sources of contamination. Additional investigations are now ongoing by potentially responsible parties with oversight and direction by DEC.
