Frontier Fertilizer Superfund Site

The 18-acre Frontier Fertilizer site is located near the eastern boundary of Davis, California. The Barber and Rowland Co. operated a pesticide and fertilizer distribution facility on the site from 1972 to 1982. The Frontier Fertilizer Co. used the site from 1982 to 1987. Both companies handled chemicals on the western 4 acres of the site. Operations consisted of storing, mixing and delivering pesticides, herbicides, and non-bulk chemicals in cans, drums, and other containers. Both the Barber and Rowland, and Frontier Fertilizer companies used a 4,000-cubic-foot former disposal basin in the northwest corner of the site to dispose of unused pesticides and fertilizers. In 1985, the California Department of Health Services, Toxic Substance Control Division placed the Frontier Fertilizer site on the State Priority Ranking List of hazardous waste sites slated for cleanup. The State began cleanup measures in April 1985. In 1994, the U.S. Environmental Protection Agency (EPA) assumed responsibility for investigation and cleanup efforts after the site was added to the National Priorities List (Superfund). EPA has been operating a groundwater extraction and treatment system since 1995.

The Mace Ranch residential subdivision is approximately 800 feet north of the site. The field immediately north of the site is planned for development as the Mace Ranch Light Industrial/Business Park.

The UC Davis Library is an information repository for the EPA Superfund documents relating the Frontier Fertilizer site and its cleanup.
