coliform bacteria what are the possible effects for consuming water with this
Coliform bacteria are often referred to as âindicator organismsâ because they indicate the potential presence of disease-causing bacteria in water. The presence of coliform bacteria in water does not guarantee that drinking the water will cause an illness. Rather, their presence indicates that a contamination pathway exists between a source of bacteria (surface water, septic system, animal waste, etc.) and the water supply.
