    Learning Objectives

    After this lab you will be able to

    1. Define the term “coliform”.
    2. Perform the Multiple Tube Test and explain the principles and each step of the test.
    3. Calculate the total number of bacteria in the food sample utilizing the SPC method.
    4. Utilize the membrane filter technique to assess and possibly quantify the presence of coliforms in a water sample.
    5. Describe the principles of the Membrane Filter Technique.

    “The most important microbiological drinking water tests are for bacteria. Water is tested throughout the systems weekly for Total Coliform bacteria. The MCL for total coliforms is 5% of all monthly tests showing positives for larger systems. The presence of Escherichia coli (E. coli) indicates fecal contamination of waters. No E. coli was detected in any drinking waters in the SCV last year.”
