Water Runoff

Nationwide, stormwater runoff is one of the great challenges of modern water pollution control, as it is a principal contributor to the impairment of waterbodies. Impervious surfaces in the urban environment, including roadways and buildings, prevent important water cycling processes for stormwater, primarily infiltration and evapotranspiration, and increase runoff relative to a natural environment. During storm events, runoff collects and transports chemical and biological contaminants as it runs over impervious surfaces, posing a threat to surface water quality. In highly urbanized areas, the excess rainfall runs off at higher volumes and velocities than would naturally occur, causing flooding and ecological degradation. Aquatic habitats and stream functions are degraded by erosion of downstream channels and deposition of sediment and pollutants caused by the force of this runoff.
