MOUNTAIN VIEW (KCBS) – An estimated 100 residents turned out for a meeting Sunday to learn more about what’s been reported as the surprising spread of toxic TCE in groundwater.
Additional test wells were expected to be used to help authorities track a new plume of the dangerous, cancer-causing solvent believed to be from old semiconductor manufacturing sites.
Within the past few weeks, it was revealed that TCE, or trichloroethylene vapors, were detected at Google’s company’s offices in Mountain View. Google’s buildings QD6, and QD7, sit on North Whisman – on top of what used to be Fairchild Semiconductor, Intel, Raytheon, and other computer chip makers.
“We have shallow contaminated groundwater,” Alana Lee, a project manager with the Environmental Protection Agency told an overflow crowd on Sunday. She suggested that plumes running beneath businesses and homes are prone to evaporation.
