The 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.
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.
Documents regarding the contaminated site can be found at the USGS Library, 345 Middlefield Road, Menlo Park, Monday through Friday between 8:30 a.m. and 4:30 p.m.
Further data is available through DTSC's Envirostor website at www.envirostor.dtsc.ca.gov/public. Enter "Palo Alto" in the city section and select "Watkins-Johnson" from the list of sites.
