Dealing with Bacteria in Your Water Supply

Bacteria can be divided into two categories, pathogenic and non-pathogenic. Pathogenic bacteria are harmful, causing diseases and illnesses ranging from E.Coli and dysentery to typhoid fever. Non-pathogenic bacteria are considered harmless and do not cause sickness.

Symptoms of Bacteria in Water

Both types of bacteria are found naturally in water, so it is important to determine if your water source has harmful or harmless bacteria. The most common bacteria found in water is iron bacteria, which feeds on iron and is considered harmless to human health. Iron bacteria is easily recognized by its red feathery floc. Pathogenic bacteria is harder to identify because symptoms depend on the type of bacteria, for example many cause gastrointestinal issues, while other types present with fever. If there is any concern about the possibility of bacteria in your drinking water, the US EPA recommends a sample of your water be tested.

Treatment Options for Bacteria in Water

There are multiple options for treating bacteria including microfiltration, chemical oxidation and disinfection, and sterilization.

  • Microfiltration
  • Chemical oxidation & disinfection
    • Chlorine injection – Chlorine fed into water at 3 to 5 ppm and a residual of 0.4 ppm of free chlorine needs to be maintained for at least 30 minutes to meet US EPA standards.
  • Sterilization
