The TRW Minerva site is located in a rural area within the village of Minerva, Ohio (population 3,900), and is over 135 acres in size. 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 the site contamination. Degreasers which contained volatile organic compounds (VOCs) were used by the facility and discharged directly to a ditch. Polychlorinated biphenyls (PCBs) were also used by the facility. The village of Minerva well field is located approximately one mile southwest of the site. In May 1985, an Administrative Order on Consent (AOC) between the Ohio Environmental Protection Agency (OEPA) and TRW was used to remediate the surface soil and sediment. In May 1986, a second AOC was agreed to by TRW and OEPA to investigate and remediate the groundwater. Site Responsibility This site is being addressed through federal, state, and potentially responsible parties' actions. Potentially Responsible Parties (PRP's) remedial activities are overseen by OEPA, pursuant to the requirements of the 1985 and 1986 AOCs. The State of Ohio entered into an Amendment to the Administrative Order on Consent with the PRPs in 2009 for additional investigation of the site.
