sand that is dredged from the intercoastal what do they do with it

One of the most creative ways the sediment is being repurposed is through creating custom soil blends to use in construction and landscaping. The state is now funding a way to repurpose the sediment through pilot projects. In Ohio, the Army Corps of Engineers dredges enough sediment to fill 220,000 dump trucks twice each year from the Cuyahoga River. In fact, as much as 50 percent of dredged Great Lake Sediment is deposited in the open lakes.

waters every year, but where does all the sand, salt, and silt go?Ĭurrently, much of the sediment is stored in containers or dumped into open waters. Environmental Protection Agency provides oversight and authorization for the disposal of dredged materials.According to a report by Madeline Urbish, a Senior Public Policy Advisor, billions if not trillions of cubic yards of sediment are removed from U.S. Army Corps of Engineers issues permits for the disposal of dredged material the U.S. The disposal of dredged material is managed and carried out by federal, state, and local governments, as well as by private entities such as port authorities. NOAA's Office of Response and Restoration plays a major role in protecting and restoring marine natural resources when environmental damage occurs. These pollutants are introduced to waterways from point sources such as sewer overflows, municipal and industrial discharges, and spills or may be introduced from nonpoint sources such as surface runoff and atmospheric deposition. This environmental dredging is often necessary because sediments in and around cities and industrial areas are frequently contaminated with a variety of pollutants. Since massive ships carry the bulk of the goods imported into the country, dredging plays a vital role in the nation's economy.ĭredging is also performed to reduce the exposure of fish, wildlife, and people to contaminants and to prevent the spread of contaminants to other areas of the water body.

This water depth continues to increase over time as larger and larger ships are deployed. Vessels require a certain amount of water in order to float and not touch bottom. It is a routine necessity in waterways around the world because sedimentation-the natural process of sand and silt washing downstream-gradually fills channels and harbors.ĭredging often is focused on maintaining or increasing the depth of navigation channels, anchorages, or berthing areas to ensure the safe passage of boats and ships. Dredging is the removal of sediments and debris from the bottom of lakes, rivers, harbors, and other water bodies.
