Contaminated Soil Capping

July 2013

Lind Marine provided material transport and vessel services for this environmental remediation project in San Francisco Bay. The project involved isolating sediment containing lead shot by mechanically dredging to remove a minimum of the top 1.5 feet of sediment and installing a protective cover over the sediment remaining in place. The remedy also included transporting and disposing the dredged sediment at a beneficial reuse site, institutional controls to minimize sediment disturbing activity, and monitoring to ensure the effectiveness of the controls and the integrity of the installed protective cover.

Approximately 8,700 bank cubic yards of sediment was removed and transferred by barge from Treasure Island to Alameda Point. A total of 1,208 tons of dredged material was classified as California hazardous waste and transported to the Clean Harbors Buttonwillow Landfill in Buttonwillow, California.
