10. Water Pollution
Point source – contaminants can be traced to a point of discharge
Contaminants usually spreading in a plume
Examples of point sources?
Examples of specific contaminants from point sources?
Nonpoint source – contaminants found in runoff moving over land or through the ground
Examples of nonpoint sources?
Examples of specific contaminants from nonpoint sources?

11. Impervious Surfaces
Roads, highways, sidewalks, driveways, parking lots, roofs, compacted soils
Cause increased runoff during rain events and prevent groundwater recharge
Dry quickly and retain heat
Increase nonpoint pollution

12. Land Use Natural Agricultural Parkland Suburban Urban Industrial
Mining
