The 5.4-acre Lorentz Barrel & Drum (LB and D) site is located in San Jose, California, about 0.25 mile from San Jose State University. The site lies directly above a major source of potable ground water in the south San Francisco Bay area, with three public water supply well fields within one mile of the site. In 1947 the Lorentz family began a drum recycling operation on 10.5 acres of land at the site. Drums containing residual aqueous wastes, organic solvents, acids, oxidizers, caustic residues and oils were received for recycling. Sometime between 1968 and 1971 the discharge was diverted to a sanitary sewer, and investigations indicate that this discharge occurred until 1984. Since 1981 several investigations have revealed soil and ground water contaminated with numerous metals, organics, and PCBs. This remedial action will address the offsite contaminated shallow ground water. The selected Expedited Response Action for this site includes: onsite ground water pump and treatment using ozone/UV for organic removal and ion exchange for nickel removal, with discharge of treated water to a local creek.
