Erosion and Sediment Control
Construction sites and other open ground areas are major contributors to soil erosion and sediment loss, which is a major source of water pollution. Bare soil exposed to a rain can become quickly eroded, leading to sediment that moves into storm sewers or lakes and streams, causing storm water pollution. Erosion control practices are designed to prevent the movement of soil particles while sediment control traps eroding soil on-site.
How can we prevent it?
Using sweepers such as the Elgin Waterless Eagle is one of the best methods for controlling and preventing soil erosion on construction sites and other open grounds. Planting vegetative or nonvegetative ground cover also helps keep soil in place, and native grasses are options that are quick to establish root systems that improve soil stability. Other options include hydro mulch or straw, which will prevent newly planted soil from eroding. Silt fences or an earth dike around the construction site, as well as a temporary swale to divert runoff or a sediment basin to catch runoff.
The National Pollutant Discharge Elimination System (NPDES) permit program controls water pollution by regulating point sources that discharge pollutants into waters of the United States. Point sources are discrete conveyances such as pipes or man-made ditches. Check with your local soil and conservation district office for information on environmentally sound Best Management Practices (BMPs).
