Exposure status: insufficient data

About this site’s exposure pathways: As of October 2024, there is insufficient information to determine the site-wide Human Exposure Control status at the Lea and West Second Street Superfund Site. Though there has been no evaluation of the human health exposure indication yet, this does not necessarily mean that unacceptable exposures are occurring. A Phased Remedial Investigation/Feasibility Study (RI/FS) at the site is ongoing and was initiated in May 2017. The phased RI/FS is collecting sufficient information and data on site contaminants to evaluate human exposure and environmental concerns and potential options for site remediation. The implementation of the investigation is slow, due to limited and incremental funding. The site was recently broken into 4 operable units (OUs), which may help in determining exposure.

Currently, the planned activities to address this pathway are to complete treatability studies at each operable unit to consider remedial alternatives which would prevent potential long-term exposure to dry cleaning constituents such as tetrachloroethylene (PCE) and trichloroethylene (TCE). The chosen remedy will be conveyed in the Record of Decision for the Site which EPA anticipates will be completed in September 2028. EPA currently anticipates controls for human exposure will be initiated at the start of Remedial Action in September 2030.

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.
