Human exposure is under control

About this site’s exposure pathways: As of August 2023, there is not sufficient information available to determine the site-wide Human Exposure Control status at the Fisher-Calo Superfund Site because of an identified potential exposure pathway for vapor intrusion (VI). The main contaminants of concern (COCs) include trichloroethylene (TCE), tetrachloroethene (PCE), chloroform and vinyl chloride. A VI investigation work plan was approved and field investigations began in 2016. Eight (8) rounds of seasonal VI investigations have taken place in multiple buildings at the Site through 2021 in three (3) areas of the Site (One Line North, One Line South & Two Line North.) To ensure that indoor air detections of contaminants were not related to VI, additional indoor and outdoor air sampling, water sampling and product testing occurred in 2022. The VI investigation results and evaluation are currently under review and a FYR Addendum is being prepared to provide the results of the 2022 investigations. The United States Environmental Protection Agency expects to complete the review and be able to make a determination on the site-wide Human Exposure Control status by the end of December 2023 at which time the Human Exposure Control status will be updated.

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.
