Anti-eutrophication If excess nutrients have resulted in de-oxygenated water, dredging may be a solution. Eutrophication affects shallow lakes and causes the dead zone in the Bay.
Contaminant remediation Dredging is sometimes used to remove chemicals washed in with storm water.
Spoil site A permanent location for sediments. Some have strong odors, too much salt for vegetation, or even contaminants and debris.
Trailing suction hopper dredge Typically used for maintenance dredging, it trails a suction pipe and loads the spoil into a hopper to transport to the spoil site.
Turbidity suspended particles in water. Muddy water can choke filter feeding organisms.
