At least 50% of the water quality problems in the U.S. result from stormwater runoff, or what the U.S. Environmental Protection Agency calls, "nonpoint source pollution".
Approximately 70% of all storm drains lead directly to rivers, lakes and estuaries and are never treated.
Five quarts of used motor oil can create an oil slick two football fields in size.
Yard fertilizer runoff from residential areas is estimated to be responsible for one third of the excess nitrogen polluting our waterways.
The first inch of runoff generally carries 90% of the pollution from a storm.
Storm drains do not go to sewage treatment plants, they lead directly to bodies of water.
Storm drains do not remove pollutants from stormwater and were designed for the specific purpose of draining water from sidewalks and streets to prevent flooding.
Water entering storm drains after it rains, picks up what is on the surface and carries it directly to our local rivers and streams untreated.
Tire wear, deteriorating brake pads, leaks of motor oil, antifreeze, battery acid, fuel, car waxes, degreasers, radiator flushes, and rust preventatives can all contribute to stormwater pollution.
Grass clippings, leaves, pet waste, fertilizers, soaps, detergents, cigarette butts, and other debris are considered pollutants that get washed into storm drains and on into our local rivers and streams.
Pollutants that contaminate stormwater are mostly considered to be non-point source pollution (surface runoff)
16 times more stormwater runoff is produced by a one acre parking lot than is produced by a meadow of the same size
