SAINT-GOBAIN PERFORMANCE PLASTICS

As of May 2026, the Saint‑Gobain Performance Plastics Superfund site is considered “Insufficient Data to make a Human Exposure evaluation” (HEID). This status does not necessarily mean that unacceptable exposures are occurring. The site includes the McCaffrey Street facility property and downgradient contaminated groundwater. The New York State Department of Environmental Conservation (NYSDEC) is the lead agency. A permanent treatment system was installed in 2017 to treat the affected public supply well, and an interim hydraulic control action began in 2019 to reduce off‑property groundwater migration toward the public supply well. EPA received a draft Remedial Investigation (RI) report, including a quantitative risk assessment, on June 25, 2024. Based on EPA’s review, the draft RI does not fully characterize source areas or delineate the extent of contamination from the McCaffrey Street site. Until those data gaps are addressed, available information is not sufficient to determine whether actual or reasonably anticipated human exposures are occurring above acceptable risk‑based levels across all pathways and areas.

Planned activities to collect sufficient information include revising and finalizing the RI to address source characterization and plume delineation; installing and sampling additional groundwater monitoring wells to define the extent, trends, and migration pathways; collecting supplemental soil and hydrogeologic data as needed; and preparing a Human Health Risk Assessment (HHRA) to evaluate relevant exposure pathways (for example, use of public and private wells and any other interactions with groundwater). EPA and NYSDEC will use the updated RI/FS and HHRA to inform remedy selection. EPA currently anticipates there will be sufficient data to make a Human Exposure determination by March 2030 because the RI is expected to be revised and finalized and a Record of Decision (ROD) identifying a remedy is expected in 2030.

If you live or work near the site, you can reduce your exposure by continuing to use public water, following any notices from your water supplier, testing private wells before use if applicable, and allowing access for sampling if requested. For more information, contact the EPA Community Involvement Coordinator Larisa Romanowski via the site webpage or at (518) 407-0400 or [email protected]. EPA and NYSDEC will continue to meet with residents and stakeholders, issue public notices and updated fact sheets, and keep the site profile on EPA’s website up to date.
