When it comes to stormwater capture, ... 59.5 million acre-feet of stormwater go uncaptured across the United States — or roughly 53 billion gallons per day. The amount is equivalent to 93% of ...
The Nationwide Urban Runoff Program (NURP) was a research project conducted by the United States Environmental Protection Agency (EPA) between 1979 and 1983. It was the first comprehensive study of urban stormwater pollution across the United States .
Topsoil runoff from farm, central Iowa (2011). Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and manufacturing industries—although laws and regulations introduced in the late 20th century have improved water quality in many water bodies.

As stormwater is channeled into storm drains and surface waters, the natural sediment load discharged to receiving waters decreases, but the water flow and velocity increases. In fact, the impervious cover in a typical city creates five times the runoff of a typical woodland of the same size.
Recovery efforts were underway across the eastern U.S. after a powerful storm inundated communities with heavy rain and caused at least 13 deaths.
Stormwater, also written storm water, is water that originates from precipitation , including heavy rain and meltwater from hail and snow. Stormwater can soak into the soil ( infiltrate ) and become groundwater , be stored on depressed land surface in ponds and puddles , evaporate back into the atmosphere, or contribute to surface runoff .
The first stormwater fee nationwide was enacted in Washington in 1974. [1] There are now nearly 1,500 jurisdictions with similar policies to address stormwater management. [ 2 ] Numerous counties in Maryland have implemented fees and programs to address polluted runoff since the 1980s. [ 2 ]
Stormwater harvesting or stormwater reuse is the collection, accumulation, treatment or purification, and storage of stormwater for its eventual reuse. While rainwater harvesting collects precipitation primarily from rooftops, stormwater harvesting deals with collection of runoff from creeks, gullies, ephemeral streams and underground conveyance.
