NPL Site Narrative for T.H. Agriculture & Nutrition Co.
T. H. AGRICULTURE AND NUTRITION CO.
Fresno, California
Federal Register Notice: June 10, 1986Conditions at proposal (October 15, 1984): T. H. Agriculture and Nutrition Co. operated a pesticide-formulating facility on about 2.5 acres near Fresno, Fresno County, California, from 1962 until 1981. Other companies had formulated pesticides on the site from 1950 to 1962. During the 1950s and 1960s, on-site landfills were used for disposal of empty containers, facility trash, and other wastes generated from the pesticide-formulation operations, including pesticide-laden clays from cleaning of equipment.
This site was first proposed for listing under the name "Thompson-Hayward Chemical Co." Thompson-Hayward Chemical Co. changed its name to T. H. Agriculture and Nutrition Co. in 1981.
Sampling conducted by the company and the California Department of Health Services detected pesticides in soil and ground water at the site. A Cleanup and Abatement Order issued by the California Regional Water Quality Control Board has directed the company to excavate contaminated soil and determine the extent of ground water contamination. In response, the company has excavated 14,000 cubic yards of contaminated soil, and has undertaken sampling to characterize soil contamination, monitor ground water, and characterize the hydrology beneath the site.
Status (June 10, 1986): The company has conducted some initial ground water studies on-site and has proposed an on-site ground water extraction and treatment system. The California Department of Health Services has ordered the company to conduct a remedial investigation/feasibility study and to develop an alternative drinking water supply program.
