  • GENERAL INFORMATION Coliforms are bacteria that are naturally present in the environment and are used as an indicator that other, potentially-harmful, bacteria may be present. WELLS:  Levels of coliform over four (4) colonies can indicate poor well construction or cleaning, or issues related to aging of the well such as the presence of holes in in the well casing. Samples indicating the presence of coliform bacteria must be tested for E. coli. HEALTH EFFECTS See E. coli, fecal coliform, and fecal indicators.
