A group of bacteria found in the intestine and faeces of most animals. Coliforms can sometimes be found in untreated water. The treatment process removes them and disinfection prevents their reappearance in the distribution system. In water receiving discharges, faecal coliform bacteria are used to indicate the presence of sewage.

Bacteria that serve as indicators of pollution and pathogens when found in water. These are usually found in the intestinal tract of humans and other warm-blooded animals.

Bacteria that live in the intestines (including the colon) of humans and other animals, used as a measure of the presence of feces in water or soil.

A group of bacteria predominantly inhabiting the intestines of humans or other warm-blooded animals, but also occasionally found elsewhere. Used as an indicator of human fecal contamination.

Indicates contamination from an unsanitary condition such as septic waste or surface water entering the water supply. Health effects include gastrointestinal illness.

Group of bacteria whose presence in drinking water can be used as an indicator for operational monitoring (Also refered to as thermotolerant coliforms, total coliforms).

Many strains of coliform bacteria are naturally present in our environment. Fecal coliform bacteria are present in the feces of humans and other warm-blooded animals but are rare or absent in unpoll [..]

A group of bacteria primarily found in human and animal intestines and wastes. Coliform bacteria (such as E. coli) are widely used as an indicator of the presence of such wastes in water.

Coliform is a type of bacteria that is present in the environment and in the feces of all warm blooded animals and humans. Coliforms themselves do not cause serious illness but are rather used as an i [..]

A group of organisms primarily found in human and animal intestines and waste, and thus widely used as indicator organisms to show the presence of such wastes in water, and the possible presence of pa [..]

Types of bacteria that are coil or helix shaped. Faecal coliform bacteria are those coliform bacteria that are found in the intestinal tracts of mammals. The presence of high numbers of faecal coliforms in a water body can indicate the release of untreated wastewater and/or the presence of animals, and may indicate the presence of pathogens.

A group of bacteria that are normally abundant in the intestinal tracts of humans and other warm-blooded animals and are used as indicators when testing the sanitary quality of water.
