SEAPLANE LAGOON REMEDIATION
Alameda, CA
Client: TetraTech/US Navy
Seaplane Lagoon is included as part of the former Alameda Naval Air Station (NAS) Superfund Site, adjacent to Alameda, California. As part of a long-term & broad cleanup effort for the naval station at large, Seaplane Lagoon is unique in that it received much of the waste water from the rest of the NAS. DMS was hired to remove contaminated sediments along the northern seawall. The main Contaminants of Concern were low levels of PCBs, however there were also trace amounts of Radium 226 within the dredging footprint.
