Deleted Date:

The site is located in a mixed industrial, commercial and residential area in South Gate, California. Volatile organic compounds, including trichloroethene (TCE), have been confirmed in the soils and ground water at the site. The Jervis B. Webb Co. conducted metal fabrication, finishing, painting and assembly operations associated with the manufacture of industrial conveyor belt systems from the 1950s to early 1996 on the southeast portion of the site. In 1997, Reliable Steel, Inc. purchased this portion of the site. The Jervis B. Webb Company purchased the northwestern portion of the site in 1975 from Spear Industries. Blake Rivet Company, which produced aluminum and stainless steel aircraft rivets, leased this northwestern portion of the site until approximately 1981.

Contaminants and Risks

Contaminated Media
  • Groundwater

TCE was detected in the groundwater beneath the site at levels up to 35,000 ppb. EPA’s Safe Drinking Water Act Maximum Contaminant Level for TCE in drinking water is 5 ppb. The full extent of the groundwater contamination needs to be fully characterized. Although the drinking water supply wells immediately downgradient of the site are located in a deeper aquifer and are not currently contaminated, there is the potential that drinking water wells may become contaminated due to connections between the aquifers. There are at least 35 drinking water wells within four miles of the site, serving approximately 226,000 people. In addition, due to the high concentrations of TCE in groundwater and the relatively shallow depth to groundwater (60 feet), there is a need to evaluate the potential for vapor intrusion of TCE from the site into nearby buildings and residential areas.
