Dredging is the practice of removing sediment like mud and silt from the bottoms of lakes (both public and private) and reservoirs to maintain waterways. One of the benefits of dredging is that boats can safely pass through harbors and trade routes without scraping along the bottom.

What many people don’t know is that this leftover dredging material can be reused to reduce how much is sent to Confined Disposal Facilities (CDF). While not all material can be reused (some may be contaminated), reusing dredged up sediment can help minimize the impact of dredging on the environment.

Produce Topsoil

Like the name suggests, topsoil is the top 5 to 6 inches of earth taken from the surface. The finer sediment in dredging material can be mixed with compost, manure, or other materials to create topsoil. For the best results, the silt from dredging is mixed with clay and sand to create topsoil perfect for growing lawns and gardens. Topsoil can even be used to improve drainage in areas of a lawn or garden that flood.

Use for Landfill Caps and Covers

Landfill caps and covers are used to protect humans and wildlife from the environmental effects of landfills. Dredging material can be used to form this protective barrier between compacted garbage and the environment. When it rains, landfill covers are designed to prevent water from seeping through layers of trash and contaminating the surrounding soil or bodies of water.

Mine Reclamation

Once mining activities are completed, the landscape will need to be restored to support local wildlife again. The silt material from dredging can be reused during mine reclamation to build up the land and make it suitable for vegetation growth. Since dredging materials can be used to produce topsoil, it is an excellent candidate for restoring land after it has been mined of its natural resources. Dredging for land reclamation can restore land for humans and wildlife.
