"Google has been forced to evacuate staff from two buildings close to it's Mountain View HQ in California due to toxic vapors seeping up from the ground below.  The dangerous air pollution is being caused by trichloroethylene, a powerful solvent also known as TCE, which has leaked into the soil and polluted the groundwater.  The pollution is the legacy of chip makers including Fairchild, Intel and Raytheon who dumped thousands of gallons of the toxic solvent into the ground when they worked in the buildings in the early days of Silicon Valley."
