[Series of eleven photos depicting toxic clean up at the former Alameda Naval Air Station.]

Excerpt:

Ominous radioactivity placards remind visitors to the western end of Alameda, Calif., an island of 70,000 in the San Francisco Bay, that they've entered a toxic site--a location the U.S. Environmental Protection Agency has added to the National Priorities List. Welcome to the former Alameda Naval Air Station.

Under legislation called the Navy Comprehensive Environmental Response, Compensation and Liability Act, the Seaplane Lagoon here at the former air station has been given priority for environmental cleanup following years of neglectful dumping of toxic chemicals from military operations.
