Why is it important to control sediment during construction activities?

Controlling sediment during construction activities is crucial primarily because of its impact on water quality and aquatic ecosystems. Sediment runoff can transport various pollutants, including nutrients, chemicals, and heavy metals, into nearby water bodies. This can lead to a range of water quality issues, such as eutrophication, which depletes oxygen in the water and harms fish and other aquatic life. By implementing sediment control measures, construction sites can significantly reduce the amount of sediment and associated pollutants that enter stormwater runoff, thereby protecting local water sources and maintaining the health of aquatic habitats.

In addition to this, while enhancing airflow, visibility reduction from roads, or increasing soil moisture might be useful in certain contexts, they do not address the primary environmental and regulatory concerns that arise during construction activities. The focus on sediment control is primarily about safeguarding water quality and the surrounding ecosystem from the adverse effects of construction-related activities.
