The Environmental Protection Agency defines stormwater as runoff generated from rain and snowmelt that flows over land or impervious surfaces, such as paved streets and parking lots, but does not soak into the ground. The runoff picks up pollutants like trash, chemicals, oils, and dirt/sediment that can harm our rivers, streams, lakes, and coastal waters.
To protect stormwater quality, a series of best management practices (BMPs) have been established to filter out pollutants and prevent pollution by controlling it at its source.

Enteric Bacteria such as Fecal Coliform, E-Coli and Enterococci normally inhabit the intestinal tract of humans and animals, and may cause illness, infections or rashes. The presence of Enteric Bacteria is an indication of fecal pollution, which may come from flooding, stormwater runoff, pets, wild life and wastewater.
If high concentrations of these organisms are ingested or enter through an open cut or sore, they may cause human illness or infection. People are advised not to gather in areas where there may be slow-moving waterways for several days after heavy rain or while water is still standing.
