Surface Water:
* Broader term: Encompasses any water that is found on the Earth's surface, including:
* Rivers, lakes, oceans, and wetlands
* Puddles, streams, and runoff
* Water in irrigation canals
* Water stored in reservoirs
* Origin: Can come from rainfall, snowmelt, groundwater seepage, or other sources.
Stormwater:
* Specific type of surface water: Refers specifically to rainwater that runs off surfaces like roofs, streets, parking lots, and lawns.
* Origin: Primarily from rainfall events.
* Characteristics:
* Typically carries pollutants like oil, chemicals, debris, and bacteria.
* Flows rapidly, creating erosion and flooding issues.
In summary:
* All stormwater is surface water.
* Not all surface water is stormwater.
Think of it this way: Surface water is the umbrella term, and stormwater is a specific type of surface water caused by rainfall.
