What is a silt curtain primarily used for?

A silt curtain is primarily used to prevent sediment from dispersing into water bodies during construction activities. It acts as a barrier, typically made of a permeable fabric, which allows water to flow through while trapping sediment, thereby minimizing water pollution and protecting aquatic ecosystems. This use is crucial during excavation, dredging, or other activities that could disturb soil and lead to increased turbidity in nearby water sources.

Using a silt curtain effectively helps ensure that sediment generated by construction is contained, allowing for better water quality management. This control measure is essential for regulatory compliance and promoting environmental stewardship in construction practices near water bodies. The design and implementation of silt curtains are aligned with best management practices in erosion and sediment control to mitigate the impacts on surrounding aquatic habitats.
