Stormwater—water runoff from rain and snowmelt that flows over land or hard surfaces.
Clean Water Act—establishes basic structure for regulating discharges of pollutants and regulating quality standards for surface waters.
Hydrology—science concerned with properties of the earth’s water, especially its movement in relation to land.
National Pollutant Discharge Elimination System—permit program that addresses water pollution by regulating point source discharging pollutants into waters (regulated in Minnesota by the Minnesota Pollution Control Agency).
Watershed—an area of land that drains or sheds water into a specific waterbody.
Bloomington is home to 15 subwatersheds that flow into four larger watersheds, all of which end up in the Minnesota River. Do you know where the water around you ends up?
Knowing where water flows is important in understanding how the land and people impact water health. In developed areas like Bloomington, pollution from all the hard surfaces, like streets and parking lots, impacts the stormwater in the city and ultimately surrounding waters and beyond.
To understand the flow of the water in Bloomington, see graphic above.
