1710 VILLA ST
The Jasco Chemical Company Superfund Site (JASCO) consists of the property located at 1710 Villa Street in Mountain View, CA. JASCO repackaged and formulated chemical products on the 2.05 acre Villa Street site from 1976 until December 1995. Bulk solvents used at the site were received by tankers and stored in eight underground storage tanks. Prior to 1985, Tank #3 was used to store pentachlorophenol (PCP), which was an ingredient of a wood preservative formerly produced by Jasco. The product was discontinued in 1985, and the tank was converted to store paint thinner. Elevated levels of volatile organic compounds (VOCs) were detected in soils from a swale area located behind the building and in the shallow groundwater. Past waste disposal practices, and possibly leakage from an underground storage tank and surface water, may have contributed to soil and groundwater contamination. The City of Mountain View has a total population of approximately 62,000. The only surface water body within one mile is Permanente Creek. Approximately 330,000 people within three miles of the site depend on groundwater for drinking water. In 1987, the City of Mountain View shut down one well near the site to determine whether site activities would affect the well. In 1988, after the investigations revealed that contamination had not migrated into the groundwater for this well, it was placed back into operation. This site has been in the Operation and Maintenance phase since 2002 when the remedy was determined to be functionally complete. The groundwater was sampled annually until 2011.
