A.46.2 Site Description
Year: 2009-present
Target Volume: 80,800 yd3
A.46.3 Remedial Objectives
Cancer in mummichogs reduced to background levels: to be fishable by 2020.
Contaminated sediment area:
- Phase 1: 7 acres including wetlands and forested shoreline
- Phase 2: 12 acres in 2012
Contaminated sediment thickness:
- Phase 1: 1 foot
- Phase 2: up to 6 ft
A.46.4 Remedial Approach
Earth moving equipment and a clamshell/bucket dredge were used for excavation.
A.46.5 Monitoring
Use of silt curtains down to bottom and absorbency booms at surface; barge/crane operated within containment. Silt curtains were placed at the top and bottom of the work areas.
Performance: Mummichog tissue sampled for cancer every 1-2 years; until cancer reduced to background levels.
- Currently work in progress.
- Dredged areas are backfilled with clean sand and topsoil.
- Petroleum sheen releases from sediment disturbances.
