• Microbiological safety is one of the most important considerations in residential water treatment. Water samples may be taken to test for Coliform bacteria. Coliform positive samples indicate the presence of E-Coli. A negative sample only proves that the well was safe at the moment the sample was drawn and frequently serve to provide false sense of security about the well at other times. Our recommendation is that every private well should include a method of disinfecting the water throughout the entire distribution system.
  • E-Coli may be found in water sources, such as private wells, that have been contaminated with feces from infected humans or animals. Waste can enter the water through different ways, including sewage overflows, sewage systems that are not working properly, polluted stormwater runoff, and agricultural runoff. Wells may be more vulnerable to such contamination after flooding, particularly if the wells are shallow, have been dug or bored, or have been submerged by floodwater for long periods of time. Although other pathogenic bacteria could be present in water, E-Coli is the most common.
