The JCI facility in Torrance, California, is part of Operable Unit 7 of the U.S. Environmental Protection Agency’s (USEPA) Montrose Superfund Site. Work at this location is conducted cooperatively with other responsible parties and USEPA under a consent decree. Terraphase has played a key role in supporting the site’s long-term environmental management and remediation strategy.

Scope of Services

Terraphase has provided technical representation to USEPA, characterized the nature and extent of releases and impacts of site operations, supported negotiations to maintain separation of responsibilities for the different releases, and designed and oversaw installation of a long-term soil-vapor extraction pilot test system, incorporating client-owned unit processes, as technically appropriate, as a cost-saving measure.

Notable Accomplishments

• Successful delineation of the different releases
• Integrated soil-vapor extraction system installation work that could be self-performed by the client into the design to facilitate additional cost reductions
• Nearly 400 pounds of chlorinated hydrocarbons have been removed in less than 3 years of system operation
