REFLECT: Pollution Map When it rains, it drains. How do you think pollution gets into local bodies of water? Open Response: ________________________________________________________________________

REVIEW: Point Source Pollution: There is an identifiable point where pollution is entering into the water. Most often, point source pollution comes through a pipe. A simple way to remember this is you can “point” out where point source pollution is coming from.

REVIEW: Non-point Source Pollution Non‐point Source Pollution: The source of pollution is not identifiable. The pollution is entering water bodies from various areas. You cannot detect or point out where it is coming from.

REVIEW: Point/Non-point Pollution Look at the pollution map. 1. Identify the sources of pollution on the map. 2. List 5 pollutants found on the map and then identify their source as point source or non‐point source: Pollutant #1: ____________ Source: _________ Pollutant #2: ____________ Source: _________ Pollutant #3: ____________ Source: _________ Pollutant #4: ____________ Source: _________ Pollutant #5: ____________ Source: _________
