Why are we concerned about stormwater?: As water moves over yards, streets, house, driveways, etc., it picks up pollutants and carries them with it. Most runoff is directed to a storm drain that drains to the river or stream. Thus, any pollutants on the land will be carried to the river potentially harming wildlife and possible drinking water sources.
