SILICON VALLEY FEARS TOXIN IS FAR WORSE THAN FIRST BELIEVED
from The Chicago Tribune

SAN FRANCISCO -- In Silicon Valley, the land of technological whiz kids,
astronomically expensive bungalows and glorious palm trees, the underside of
the computer revolution keeps seeping up--literally.

The valley, located about 25 miles south of San Francisco, has been
struggling for more than a decade to deal with semiconductor manufacturing
solvents that have seeped into the groundwater, a problem that has made
pricey Silicon Valley the home of the largest concentration of Superfund
toxic waste sites in the nation.

Now the news is worse: The Environmental Protection Agency said last week
that the suspected carcinogen trichloroethene, known as TCE, may be many
times more harmful than originally thought, and that vapors from the
substance have been found inside homes and office buildings.
