Readers have been checking in to inquire about these signs that recently went up along a fenced-off area on Alameda Point. Turns out the Navy has begun its cleanup of Seaplane Lagoon.

The cleanup effort, which began on January 22, will involve dredging some 79,000 cubic yards of soil from 10 acres in the northeast and northwest corners of the lagoon. The soil will then be left out to dry and then disposed of. Wastewater will be treated on-site and then used to tamp down dust caused by the cleanup effort, put back into the lagoon or taken off-site. The cleanup is expected to take a year.

The soil to be dredged contains cadmium, chromium, lead, polycholrated biphenyls and DDT and other pesticides, a Navy fact sheet on the cleanup effort says. The Navy suspects the soil could also contain low levels of radium 226, the material used to paint plane dials on the Point during World War II.

“There is no danger to the health and safety of people working, living and visiting the base,” said Derek Robinson, environmental coordinator for the base. He said the Navy has been coordinating with the city to do the work.

More information on the cleanup effort is available at the Main Library, 1550 Oak Street, or the City Hall West, 950 West Mall Square, Alameda Point.
