"Cleanup of Silicon Valley Superfund Site Takes Environmental Toll"

"Below some of the world’s most expensive real estate, in the heart of Silicon Valley, pipes and pumps suck thousands of gallons of contaminated water every hour from vast underground toxic pools.
Giant industrial filters trap droplets of dangerous chemicals at the surface, all in the hope of making the water drinkable again and protecting the workers of tech giants such as Google Inc. and Symantec Corp. from toxic vapors.

But that costly journey to the surface is only the start of a toxic trail with no clear end.

Once it leaves Mountain View, Calif., the toxic waste gets shipped, treated and burned in places like Oklahoma and Arizona, discharging waste in small towns and on a Native American reservation, and in some cases creating even more harmful chemicals, The Center for Investigative Reporting has found."
