coliforms
Fecal indicator organisms
Coliforms are a group of bacteria found in the intestines of warm-blooded animals and in soil.
Their presence in water or food indicates possible fecal contamination and potential exposure to disease-causing organisms.
Water quality testing routinely measures coliform levels: The well tested positive for coliforms and was declared unsafe for drinking.
