TORONTO, Ohio (Dec. 19, 2019) --The U.S. Environmental Protection Agency (EPA) recently finished air sampling and has installed vapor mitigation systems at residential properties near the former Hancock Manufacturing Co. facility at 709 N. Fifth St. in Toronto, Ohio.

Metal cleaning operations by the company contaminated soil and groundwater in the area with trichloroethylene, or TCE. U.S. EPA sampled indoor air in 19 residences and installed sub-slab depressurization systems in 12 residences where indoor air contamination exceeded U.S. EPA’s health standards.

Ohio EPA referred the site to U.S. EPA in 2017 after indoor sampling showed elevated levels of volatile organic compounds, or VOCs.
