The mines – and the town – were abandoned a generation ago, but high levels of mercury are now gushing out of the more than 80 miles of tunnels. During wet years the toxic waters flow into the San Joaquin River, which drains into the Delta and then the Bay.

In addition to the mercury, asbestos and sulfuric acid has also been found in the waters, according to researchers.

“Most of this stuff was locked deep in the earth,” said Stanford University earth sciences Professor Gordon Brown. “And by deep, I mean several miles down.”

One of the few residents of New Idria, Kate Woods, lives amid the toxics she has tried to get cleaned up for more than 20 years.

“It’s ghastly,” she quipped, looking at a rust red creek running through the handsome California countryside where abandoned town of New Idria sits quietly away from most environmental activists.

Despite the conditions, Woods says she’s staying...
