Description and History

NPL Listing History

NPL Status: Final

Proposed Date:

Final Date: 05/10/12

Deleted Date:

The Site is located in a mixed industrial, commercial, and residential area in South Gate, California. Volatile organic compounds, including trichloroethylene (TCE), have been found in soils and ground water at the Site. From 1972 to 2013, the Site was occupied by a facility that manufactured hot-melt adhesive tape for laying carpets. Prior to 1972, Pacific Screw Products Corporation manufactured screw products at the property until the business went bankrupt. On the property, the main areas of concern include concrete liners in the pallet manufacturing area, a sump and an underground storage tank area. Historical Los Angeles County Department of Health Services Hazardous Waste Control Program surveys and notices of violations note the use of TCE on the property and improper disposal of unusable oils and solvents.

Contaminants and Risks

Contaminated Media
  • Groundwater

Soil and groundwater at the Site, and down gradient of the Site, are contaminated with TCE. TCE was detected in onsite soils at levels up to 17 parts per billion (ppb) and in groundwater beneath the Site at levels up to 17,000 ppb. EPA’s Safe Drinking Water Act Maximum Contaminant Level for TCE in drinking water is 5 ppb.

The extent of the ground water contamination is currently under investigation. However, 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 soil gas, EPA evaluated the potential for vapor intrusion of TCE into nearby residential areas.
