The type and levels of the contamination present will determine the options that are available for beneficial use or disposal.

The proper management of contaminated sediments is a complex process. Contaminants enter waterways from many sources including surface runoff, municipal and industrial discharges, historical industrial practices, chemical spills and other sources. These dredge projects serve a critical role in protecting human life, water treatment systems, property and environment while ensuring safe shipping of goods to the market.Įnvironmental dredging targets the reduction of additional contaminate exposure by preventing the spread of contaminated sediments to other areas. Every year, the USACE must oversee the removal and management of millions of cubic yards of dredge spoils. Navigational dredging is an ongoing maintenance initiative that is under the direction of the US Army Corp of Engineers (USACE). Flood control and management during high flow conditions through a watershed.Environmental dredging to remove excess sediment in sensitive habitats or to remove contaminated sediment containing toxic materials that could adversely affect human health and the environment.To perform navigational dredging for maintaining safe shipping channels, ports, harbors, dams and bridges.The most common reasons for dredging a water body are: Dredging is the process of removing excess sediment, contaminated sediments and debris from aquatic ecosystems.
