Mound, Ohio, Site

Remediation of the Mound, Ohio, Site was conducted in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

The site long-term monitoring responsibility transferred to the Office of Legacy Management (LM) in 2010. An amendment was made to the Operable Unit-1 Record of Decision in 2023, which allowed for the removal of the pump and treat remediation system in 2024. With the treatment system removed, current responsibilities at Mound include groundwater monitoring, institutional controls monitoring, records-related activities, and stakeholder support. DOE has transferred ownership of 100% of the site and LM's Mound office was consolidated with the Fernald Preserve office in Harrison, Ohio.
