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?
impervious surfaces
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
land use
