Per EPA Superfund website (www.epa.gov/superfund/industrial-excess-landfill):
Starting in April 2022, the PRPs began sampling private residential wells for dioxane contamination. Of the 110 private wells sampled, a mix of 35 primary and secondary use (e.g., irrigation) wells had detections of 1,4-dioxane. Residents with primary use well impacts are being provided water. To date, 27 homes have been connected to municipal water and additional connections are underway. A map of the focused area of investigation along with validated 1,4-dioxane data is available here.
The responding PRP will transition from sampling private residential wells to investigating the nature and extent of the 1,4-dioxane groundwater plume beyond the Site boundary. Throughout the winter and spring, workers will conduct activities such as sampling surface water, drilling temporary boreholes to collect groundwater samples, and installing permanent monitoring wells in the direction of the groundwater at the Site. The data will be used to update the protectiveness determination in a FYR report addendum which should be completed by December 2023. More information about the direction of groundwater flow and its relationship to the Site is available here: Groundwater Flow Direction At The Industrial Excess Landfill (IEL) Superfund Site, Uniontown, Ohio(PDF) (9 pp, 594.09 KB)
