Watershed Biology
Frederick E. Maier
Spring Brook Nature Center
Itasca, Illinois

Students test local watersheds for possible sources of pollution. Groups of students survey a small watershed in their area, testing the water for specific chemicals including dissolved oxygen, pH, nitrate, ammonia, chlorine, and phosphate. Students determine if there are pollution problems in the watershed, identify the types of pollution, and determine if the pollution originates from point sources or non-point sources. After analyzing data, the class makes recommendations to town or city planners on steps to correct the pollution problems.
