What does "sediment pollution" refer to in stormwater management?

Sediment pollution in stormwater management specifically refers to the introduction of soil particles into water bodies as a result of erosion. When rainwater flows over land, it can pick up loose soil, sand, and other particulate matter, carrying them into streams, rivers, lakes, and other water bodies. This process can lead to increased turbidity, which negatively affects aquatic habitats, disrupts photosynthesis in aquatic plants, and can harm fish and other wildlife.

The issue of sediment pollution is particularly significant because it not only degrades water quality but can also contribute to additional problems such as nutrient loading, habitat destruction, and increased flooding severity. Effective stormwater management practices often aim to reduce erosion and the subsequent transport of sediments, thereby protecting both water quality and aquatic ecosystems.
