Chapter 10 - MICROBIOLOGICAL ANALYSES
Thus the presence of total coliforms may or may not indicate faecal contamination. In extreme cases, a high count for the total coliform group may be associated with a low, or even zero, count for thermotolerant coliforms. Such a result would not necessarily indicate the presence of faecal contamination.

The presence of E. coli in a water sample represents an even greater health risk than the presence of total coliform bacteria. ACCEPTABLE RESULTS: 0 coliform/100 milliliters (ml) of water. If you have coliform bacteria present, you should resample. If a second test
