EPA Superfund Site

PIKE AND MULBERRY STREETS PCE PLUME

IN | EPA ID INN000508678

Human exposure is under control

About this site’s exposure pathways: As of July 2024, the Pike and Mulberry site is considered "Current Human Exposure Not Under Control" because residents and workers are likely being exposed to soil vapor contamination via the vapor intrusion (VI) pathway as PCE and TCE concentrations in soil vapor at the site are hundreds of orders of magnitude greater than sub-slab soil vapor action levels established in the Record of Decision. EPA plans to install a soil vapor extraction (SVE) system at the site, has been conducting VI sampling at occupied structures in the area, and has installed mitigation systems at 16 properties exceeding VI clean-up levels. EPA is continuing to pursue access at properties for sampling and mitigation. EPA estimates human exposures will be under control by the end of November 2027 after it has completed installation of the SVE and any additional mitigation systems that may be needed.

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.
