Eroding Our Futures | Sediment and Water Quality Ever wondered at the murky water of a stream or river following a rainstorm, in contrast with its clearer waters the day before? At the heart of the situation is the unhealthy relationship between stormwater runoff and sediment that arrives from many sources in our developed environments, including bare soil on construction sites, poorly maintained dirt and gravel roads, eroded streambanks cut by flash floods, and anywhere soil is disturbed. Sediment buildup on the stream bed degrades this essential habitat for aquatic insects, fish, amphibians, and other wildlife; pollutants such as heavy metals, excess nutrients, and bacteria attach to sediment particles and are carried downstream.
