Description and History

NPL Listing History

NPL Status: Final

Proposed Date: 06/24/88

Final Date: 10/04/89

Deleted Date:

The Brown & Bryant, Inc. (Arvin Plant) covers about 5 acres in Arvin, California. The company began operations in 1960 as a formulator of agricultural chemicals including fertilizers, herbicides, insecticides, and fumigants. During inspections by State agencies, improper handling and disposal of hazardous wastes at the facility have been documented. Accidental spills of pesticides have occurred at the site. In 1979, an evaporation pond was built in the southeastern corner of the site. When the facility was operating, the pond received pesticide rinse water and surface runoff from the site. As a result of heavy rains, this pond overflowed on at least two occasions. The closest public well is located about 1,700 feet south and downgradient of the site. The Arvin Community Services District maintains six municipal groundwater wells within 1 mile of the site. The public water system supplies drinking water to approximately 7,800 people and irrigates about 19,600 acres of cropland. The area surrounding the site is industrial, agricultural, and residential.

Contaminants and Risks

Contaminated Media
  • Groundwater
  • Soil and Sludges

Soil contains numerous pesticides such as dinoseb, ethylene dibromide and other fumigants. The groundwater also is contaminated with pesticides. People who accidentally ingest or come into direct contact with contaminated groundwater or soil may be at risk.

Investigation and Cleanup Activities

Initial Actions

Interim Actions: In 1988, under State supervision, Brown & Bryant, Inc., excavated the heavily contaminated soil under the pond and installed a liner. An additional removal of dinoseb-contaminated soil was conducted in 1991. The excavated soil was cleaned, treated, and returned to the ground. The water used to clean the soil was treated by an innovative technology called ultraviolet/ozone. This process uses special ultraviolet lights and ozone gas to break down hazardous chemicals. In addition, more monitoring wells were installed to detect any contaminants migrating to the Arvin Municipal wells and to monitor the perched water plume.

Remedy Design

Entire Site: The EPA began an investigation in 1990 to develop a long-term solution to the groundwater and soil contamination problems. A remedy was selected in 1993 that includes consolidation of contaminated soil, installation of a cap over the consolidated soil, and extraction and treatment of water from the first water-bearing unit. Design of the remedies was completed in early 1997. A Resource Conservation and Recovery Act (RCRA) cap and a non-RCRA cap was built over the Brown and Bryant facility in 1998.

Site Studies

Area-Wide Groundwater: An investigation to explore the nature and extent of the area-wide groundwater contamination was completed in the 2005 Remedial Investigation and Feasibility Study. A Proposed Plan was sent out for public comment in June 2007, and the final remedy was selected in a Record of Decision signed 9/28/07.

Remedy Selected

Groundwater Remedy: The overall strategy to reduce groundwater contamination involves extraction and treatment of the groundwater in the shallower A-zone, which is the source of contamination to the B-zone. In addition, institutional controls will be placed on the Site and nearby properties to prevent the use of B-zone groundwater until drinking water standards are attained. The remedy also requires relocation of the Arvin City Well CW-1 to remove the threat of cross contamination from the A-zone and the B-zone to the C-zone.

EPA is waiting for the Arvin Community Services District [ACSD] to submit their application for a cooperative agreement that will fund a replacement for CW-1 well.

Under orders from the State, Brown & Bryant, Inc., conducted a limited investigation of the site and removed some of the contaminated soil. However, in 1989, the firm went out of business, leaving the EPA and the State to solve the remaining contamination problems.

Cleanup Results to Date

The removal and treatment of the heavily contaminated soil has reduced the potential for exposure to hazardous materials while the EPA continues implementing cleanup actions at the Brown & Bryant, Inc. (Arvin Plant) site.
