EPA Superfund site
LEEDS METAL
Exposure status: insufficient data
Data limitations: Proximity to a Superfund site boundary does not mean your property is contaminated. EPA site boundaries show the area designated for cleanup, not the full extent of contamination. Groundwater plumes can extend beyond site boundaries. This tool shows publicly available EPA federal data. It is not affiliated with or endorsed by EPA, and is not a substitute for a professional environmental assessment.
About this site's exposure pathways
As of May 2026, the Leeds Metal Superfund Site is considered ‘Insufficient Data to make a Human Exposure evaluation’ (HEID).” The site was listed on the National Priorities List (NPL) in September 2012, and EPA has been implementing the Remedial Investigation/Feasibility Study (RI/FS) under a Potential Responsible Party (PRP)-negotiated Scope of Work (SOW). Multiple draft Remedial Investigations (RI) reports have been submitted (May 2023, June 2024, November 2025, March 2026, and April 2026). The Human Health Risk Assessment (HHRA) and the Screening Level Ecological Risk Assessment (SLERA) have been completed as separate documents and approved by EPA. The principal item preventing an HEC determination is resolution of groundwater data gaps related to volatile organic compounds (VOCs) and per- and polyfluoroalkyl substances (PFAS) in local residential drinking water well/s, including whether additional well/s should be sampled and/or included for treatment. Additional sampling is scheduled for Fall 2026, after which a better-informed HEC determination can be made.
