Health and Environmental Effects

Discharges of stormwater runoff can have a significant impact on water quality. Several studies reveal that stormwater runoff from urban areas can include a variety of pollutants, such as sediment, bacteria, organic nutrients, hydrocarbons, metals, oil and grease.

Sediment-laden runoff results in increased turbidity and decreased oxygen in a stream, which in turn results in loss of in-stream habitat for fish and other aquatic species. It can kill fish directly, destroy spawning beds, and suffocate fish eggs and bottom-dwelling organisms.

Sediment-laden runoff can increase difficulty in filtering drinking water, resulting in higher treatment costs, and can result in the loss of drinking water reservoir storage capacity and decrease the navigational capacity of waterways. It also blocks light and reduces growth of beneficial aquatic grasses.
