FRANKLIN STREET GROUNDWATER CONTAMINATION

IN | EPA ID INN000510959

Exposure status: insufficient data

About this site’s exposure pathways: As of August 2025, there is insufficient information to determine the site-wide Human Exposure Control status at the Franklin Street Groundwater Contamination Superfund Site. A Remedial Investigation/Feasibility Study (RI/FS) will be needed to fully characterize the nature and extent of contamination and to determine exposure and potential risk from any contamination identified at the site. The RI/FS began in March 2024 and initial soil and vapor intrusion sampling has been conducted. Groundwater, and source area sampling continues. Potable well sampling and sewer testing will be conducted through winter 2025. Quarterly groundwater sampling will continue through 2025.

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.
