  1. Aquatic Indicators Text: Ted Schaffer Editor: Laurie Rosenberg Assistant Editor: Nadine Smith Illustrator: Jamie Buckwalter MUHLENBERG COLLEGE

  2. Living Things as Indictors of Water Quality

  3. Esherichia Coli (E. Coli) http://www.bact.wisc.edu/Bact330/lectureecoli

  4. E. Coli Colonies on Agar Plate http://www.bact.wisc.edu/Bact330/lectureecoli

  5. Dissolved Oxygen Testing

  6. Collecting Aquatic Organisms

  7. Fast running streams with cold water - high dissolved oxygen levels. Still, shallow bodies of water - low dissolved oxygen levels.
