2 What is stormwater? Water Resources Program

3 Water Resources Program The Natural Hydrologic Cycle

4 Water Resources Program The Impact of Development on Stormwater Runoff 10 % 20 % 30% 55% More development More impervious surfaces More stormwater runoff

5 Water Resources Program The Urban Hydrologic Cycle

6 Water Resources Program Water Pollution Sources POINT SOURCE POLLUTION NONPOINT SOURCE POLLUTION Environmental Health Perspective, National Institute of Health

7 Water Resources Program Point Source Pollution Comes from a specific source, like a pipe Factories, industry, municipal treatment plants Can be monitored and controlled by a permit system (NPDES)

8 Water Resources Program Nonpoint Source Pollution Nonpoint Source (NPS) Pollution is pollution associated with stormwater or runoff NPS occurs when runoff collects pollutants on its way to a collection system or water body NPS pollution cannot be traced to a direct discharge point such as a wastewater treatment facility

9 Impacts of Nonpoint Source Pollution Fish and wildlife Recreational water activities Commercial fishing Tourism Drinking water quality Water Resources Program

10 Water Resources Program What is infrastructure? Infrastructure includes the basic structures and organizations needed to operate our cities: roads water supply sewers electrical grids telecommunications
