The murky and complex topic of groundwater contamination has been a hot one in cities like Palo Alto and Mountain View, where contamination has been found under former computer chip manufacturer sites around North Whisman Road and a few other sites. The typical pollutant is trichloroethylene (TCE), a once-popular industrial solvent that has been deemed a carcinogen by the Environmental Protection Agency. The vapors are known to rise from the ground and become trapped in buildings, causing a risk for birth defects from short term exposures and numerous health problems from long-term exposures.
