Superfund Site: TRW, INC. (MINERVA PLANT)

Superfund Site Profile


The 135-acre TRW, Inc. (Minerva) site is located in Minerva, Ohio. A TRW facility, sold in 1986 to another entity, is located on the property and produces aircraft components. Past disposal practices associated with the facility were responsible for site contamination. Degreasers containing volatile organic compounds (VOCs) were used by the facility and discharged directly to a ditch. The facility also used polychlorinated biphenyls (PCBs). Site cleanup and monitoring are ongoing.
