In this experiment, students will test control and environmental water samples for the presence of total coliform bacteria and E. coli using color changing enzyme assays. Testing drinking water for every possible type of pathogenic bacteria is slow and costly. Thus, drinking water is tested for coliforms - including the familiar E. coli. Presence of coliforms is an indicator of fecal contamination.
