| Abstract |
The Teledyne Semiconductor site is comprised of two Superfund sites: the Teledyne Semiconductor site, a semiconductor manufacturing facility, and the Spectra-Physics site, a laser and related components manufacturing facility, and offsite areas associated with a contaminated ground water plume in Mountain View, California. Land use in the area is predominantly commercial and industrial. In 1980, all underground solvent handling activities were discontinued and waste holding and disposal facilities were moved above ground. Spectra-Physics, Inc. has manufactured lasers and associated components onsite since 1963, and has used VOCs including TCE as part of the manufacturing processes. Wastewater and rinse water were discharged through five below-grade sumps into the sanitary water system. From 1982 to 1984, State investigations identified the release of VOCs from solvent tanks into onsite soil at both areas. The Record of Decision (ROD) addresses contamination of the ground water aquifers and onsite soil. The primary contaminants of concern affecting the soil and ground water are VOCs including PCE, TCE, toluene, and xylenes. The selected remedial action for the site is included. |
