Coliforms are a broad class of bacteria found in our environment, including the feces of man and other warm-blooded animals. The presence of coliform bacteria in drinking water may indicate a possible presence of harmful, disease-causing organisms.Why use coliforms to indicate water quality?oliforms are a broad class of bacteria found in our environment, including the feces of man and other warm-blooded animals.

Total coliform, fecal coliform, and E. coli are all indicators of drinking water quality: 1  Total coliform bacteria are found in the environment (soil or vegetation) and are usually harmless. 2  Fecal coliform bacteria are a sub-group of the total coliform group. 3  E. coli is a subgroup of the fecal coliform group. They are also found in the intestines of people and warm-blooded animals. Most E. coli are harmless but some strains may cause serious illness. E. coli in a drinking water sample indicates recent fecal contamination, meaning other pathogens are likely present.
