PLYMOUTH & COLONY STS
The CTS Printex Superfund Site comprises a number of properties and is situated in the northwest corner of the Santa Clara Valley between the south end of San Francisco Bay and the Santa Cruz Mountains in the City of Mountain View, California. CTS Printex operated a printed circuit board manufacturing facility within a 5½-acre portion of the area bounded by Plymouth, Colony, and Sierra Vista Streets from 1970 to early 1985. Metals and degreasing compounds (e.g., organic solvents) were discharged to soil and groundwater during CTS Printex’s manufacturing operations. Investigation and remediation, including soil excavation and groundwater extraction, were undertaken by CTS Corporation and Nearon Enterprises between 1985 and 1996. The down-gradient portion of the Site bounded by Plymouth Street and Sierra Vista Avenue still requires additional monitoring, investigation, and potentially remediation for VOCs in groundwater; however, residual concentrations of VOCs in groundwater have been decreasing and are anticipated to continue to decrease over time. For one up-gradient portion of the Site,(Gables End, 1901-1950 Cambridge Drive, 841-862 Avery Drive, 1900-1929 Aberdeen Lane, 851-863 Donovan Way, 1901-1941 Newbury Drive) a risk management plan was developed, a restrictive covenant was recorded, and mitigation measures (e.g., vapor barriers and sub-slab ventilation systems) were implemented to address potential VOC concerns through the vapor intrusion pathway. EPA amended the Record of Decision in September 2011. In 2014, EPA entered into a Consent Decree with CTS Corporation and ADN to implement the updated clean up.
