EPA Superfund site
KOKOMO CONTAMINATED GROUND WATER PLUME
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 September 2026, the Kokomo Contaminated Groundwater Plume Superfund site is considered ‘Insufficient Data to make a Human Exposure evaluation’ (HEID) because a Remedial Investigation/Feasibility Study (RI/FS) has not been completed to provide the necessary information. The following contaminants have been detected in the groundwater plume: trichloroethylene; 1,1-dichloroethane; 1,1-dichloroethene (DCE); cis-1,2-DCE; trans-1,2-DCE; and vinyl chloride (VC). VC and cis-1,2-DCE are the principal contaminants detected. EPA will collect groundwater samples and evaluate possible exposure pathways, including ingestion, dermal contact, and inhalation, as part of the RI/FS and human health risk assessment. Community involvement interviews and development of a Community Involvement Plan are planned for 2027. A determination on the Human Exposure Control status is expected to be made in December 2027 because a sufficient amount of the RI/FS sampling will be completed by then.
