LITTLE SCIOTO RIVER

OH | EPA ID OHN000509950

Human exposure is NOT currently under control

About this site’s exposure pathways: As of August 2025, the Little Scioto River site is considered "Current Human Exposure Not Under Control" due to contaminated sediment in the Little Scioto River, which is operable unit (OU) 1. The risks are driven by potential exposure to carcinogenic polyaromatic hydrocarbons (PAHs) and benzo(a)pyrene equivalents in the sediment. The United States Environmental Protection Agency (EPA) issued a Record of Decision in Jun. 2016 to address OU1. The OU1 remedy started construction in fall of 2023. The Baker Wood Creosoting facility, OU2, has soil and groundwater contamination present onsite. EPA selected a remedy for OU2 in the Sep. 2022 Record of Decision and is currently in the process of designing the selected remedy. EPA will ensure any unacceptable risks are addressed. Human exposures are expected to be under control with remedy implementation. Community outreach includes public meetings and informational mailings.
