1. Stormwater Runoff and Water Quality

2. Stormwater Runoff G Definition: Rainfall that, instead of soaking into the ground, flows into water bodies picking up pollutants along the way G Definition: Rainfall that, instead of soaking into the ground, flows into water bodies picking up pollutants along the way http://www.kytc.state.ky.us/EnvAnalysis/Stormwaterquality/Gen_info_edu.htm

3. River Basin G Definition: defined area where all water within the area flows into a common water body G There are 17 different river basins in NC G You live in the Pasquotank River Basin, which has the fewest number of people and the most national wildlife refuges in the State!

5. Pollution G As stormwater flows across streets and lawns, it picks up chemical pollutants G All pollution in a river basin accumulates in the common water body G As stormwater flows across streets and lawns, it picks up chemical pollutants G All pollution in a river basin accumulates in the common water body

6. Types of Pollution Point Source Pollution G Definition-localized source of pollution, usually industrial and coming from a pipe G Examples G Industry Nonpoint Source Pollution  Definition- general and indirect water pollution from many diffuse sources G Examples G Agricultural Runoff G Animal Waste G Residential Property Runoff G Parking Lot and Road Runoff http://www.liverpool.nsw.gov.au/LCC/INTERNET/me.get?site.sectionshow&PAGE1230&BODY

8. Visual Indicators of Water Quality G Diverse Organisms G Bugs as Indicators of Water Quality Mayflies and Caddisflies cannot tolerate water pollution, therefore their presence in a water body indicates good water quality.

9. Measuring Water Quality G Dissolved Oxygen G Water Temperature G pH G Extremely high or low levels of any of these indicate poor water quality G Dissolved Oxygen G Water Temperature G pH G Extremely high or low levels of any of these indicate poor water quality A YSI Meter is used to measure these quantities.

10. How do we cleanse our waters?! G Riparian buffers G Wetlands G Stormwater Best Management Practices G Raingardens, Cisterns, Rain Barrels, Permeable Pavement G Riparian buffers G Wetlands G Stormwater Best Management Practices G Raingardens, Cisterns, Rain Barrels, Permeable Pavement
