Why do we test for indicator bacteria instead of pathogens to determine if water is healthy?
Testing for pathogens is difficult.

Water carries many kinds of pathogens, including bacteria, viruses and protozoa. Each type of bacterium, virus or protozoan requires a different test. Many of these tests are expensive because they require special materials, equipment and/or are time-consuming. It is difficult to monitor water for every pathogen on a routine basis.
