Dredging Today: USA: Navy Performs Dredging at Alameda Seaplane Lagoon, February 27, 2012


As described in a Fact Sheet published December 22, 2011, the Department of the Navy is currently performing dredging at the former Naval Air Station (NAS) Alameda Seaplane Lagoon. The purpose of this work is to protect human health and the environment by removing contaminated sediments. The Navy is aware of some recent concerns regarding equipment noise have been expressed about work being performed during the night.

The dredge barge generator used to supply power for the work is the primary source of noise associated with the cleanup operations, and a muffler has been in place since the beginning of the project to reduce noise. The Navy is attempting to install a more effective muffler to further reduce the noise level and expect the nighttime dredging will be completed later this month or early March, 2012.
