The Firestone Tire & Rubber Co. (Salinas Plant) site consists of a 43-acre former tire manufacturing plant on a 256-acre parcel of land. The site is an industrial park containing warehouses. Firestone operated a tire manufacturing plant on the site from 1965 to 1980. Production chemicals apparently were spilled during the manufacturing process. The major chemical types and raw materials that were used at the plant include carbon, rubber, processing oil, zinc oxide, solvents, anti-oxidants, steel wire, and petroleum fuels. Solid and hazardous wastes from the manufacturing processes were disposed of in off-site facilities. Aqueous industrial wastes and domestic wastewater were treated at two on-site treatment plants. In 1980, Firestone received a permit to store hazardous wastes. Seventy-nine drums were stored on a concrete pad on site. Flammable liquids were stored in 52 drums, and 27 drums contained corrosive liquids. In 1981, these drums were removed to a licensed disposal site. The contamination at the site was first discovered in 1983, during the plant closing. In 1983, 20 monitoring wells were installed for groundwater investigations, and soil samples were taken. An estimated 400 drinking water wells have been identified in the area. Approximately 120 people reside within a 1-mile radius of the site, and 14,000 people live within a 4-mile radius.

This site has been deleted as of April 21, 2005.

Contaminants and Risks

Contaminated Media
  • Groundwater
  • Soil and Sludges

Groundwater contains volatile organic compounds (VOCs). Soil was contaminated with VOCs. Health threats posed by direct contact with contaminated soil have been eliminated. While no exposure has been documented, people may face a health threat by ingesting, coming into direct contact with, or inhaling vapors from contaminated groundwater until treatment is completed.

Investigation and Cleanup Activities

Initial Actions

Initial Actions: Contaminated soil was removed from 1983 to 1984. Soil capping was performed in 1984 and 1985. On- and off-site shallow aquifers were treated in 1986 and 1987.

Cleanup Ongoing

Entire Site: In 1989, the California Department of Health Services and the EPA announced the approval of a cleanup remedy. The plan called for Firestone to install five new extraction wells to extract groundwater from the intermediate aquifer and to continue pumping from the wells located in the shallow aquifer. The extracted groundwater will continue to be treated by the existing treatment plant before being discharged into the Salinas River. Construction of the cleanup remedy was completed in late 1991. Monitoring of the aquifers continues. Recent monitoring has shown that the cleanup action has significantly reduced the size of the contaminated groundwater plume. Treatment is scheduled to continue until 1999 when all site cleanup goals are expected to have been met.

Cleanup Complete

In June 1992, the groundwater cleanup levels were achieved in all hydrological zones, and the groundwater extraction and treatment system was shut down. Groundwater monitoring continued until July 1998. EPA issued the Final Closeout Report for the Site in 2004 and deleted the Site in April 2005.

Cleanup Results to Date

Construction of all cleanup remedies has been completed. The removal and capping of the contaminated soil and the extraction and treatment of contaminated groundwater have reduced the potential of exposure to contaminants at the Firestone Tire & Rubber Co. (Salinas Plant) site while final groundwater treatment activities are underway.


Cleanup of contamination at the Site has been completed
