Toxics cleanup study to begin at Palo Alto siteContamination at former Watkins-Johnson facility in Stanford Research Park to be examined
by Sue Dremann Palo Alto Weekly (CA) May 1, 2014The site of a former electronics firm in Palo Alto will soon undergo a pilot study for possible cleanup of hazardous materials deposited there since the late 1950s, the California Department of Toxic Substances Control has announced.
The contamination is located at the former Watkins-Johnson facility at 3333 Hillview Ave. in the Stanford Research Park. Hazardous levels of volatile organic compounds, or VOCs, such as tetrachloroethylene and trichloroethylene were found in the groundwater during an investigation of site soil and water between 1991 and 1993, according to the DTSC. The site was first developed in 1958 for the design, development and manufacture of advanced electronics for military, industrial and space applications. Cleanup has been underway since 1995.
A pilot study starting on May 5 will examine using microbes that ingest hazardous chemicals and change them into benign substances. Workers will inject an emulsified vegetable oil into existing wells on the site and two weeks later, they will add injected dehalococcoides microbes, which are expected to enhance the breakdown of chemicals at the site and are commonly used for bioremediation projects of this nature. The sampling and injection areas may be blocked off during the trial period, which is expected to last two weeks, DTSC officials said.
