What is one common method used for sediment control in industrial areas?

Silt fences are a widely recognized method for sediment control in industrial areas, particularly during construction or grading activities. These temporary barriers are typically made from geotextile fabric and are deployed to prevent sediment from leaving a construction site and entering adjacent water bodies. The way silt fences function is by trapping sediment that is carried by stormwater runoff, allowing cleaner water to pass through while retaining the sediment. This is critical in maintaining water quality and preventing pollution in nearby rivers, lakes, and streams, which is especially important in areas where industrial activities occur.

The use of silt fences is regulated and often mandated to comply with environmental protection standards, particularly under the National Pollutant Discharge Elimination System (NPDES) permits. Their effectiveness lies in the simplicity of installation and the ability to adapt to varying site conditions. Silt fences are an essential component of a broader erosion and sediment control plan and are often used in combination with other best management practices to ensure comprehensive sediment management.
