Total Coliform
Group of common bacteria found in soil, water, and the gut and fecal waste of humans and other warm-blooded animals
EPA MCLG Level
0 ppb
Maximum level that poses minimal health risk based on the latest science
Health Effects
While not all coliform bacteria cause illness, these bacteria can indicate the presence of other harmful pathogens in water. Additionally, certain strains of E. coli, a species of coliform bacteria, can cause severe illness impacting gastrointestinal, blood system, and renal endpoints. These health effects are primarily a danger to young children, the elderly, and people with compromised immune systems.
Affected Organs & Systems:
Common Sources
- Most coliform bacteria are harmless and widely present in the environment
- However, a subset of coliform bacteria, called fecal coliforms, are found exclusively in the digestive tracts of humans and other animals
- Agriculture and livestock waste, as well as poorly maintained septic tanks or sewage disposal systems, can lead to fecal coliform contamination in source water
How to Remove It
Water filters certified under the following NSF standards are effective at removing Total Coliform:
