total coliform

Total coliforms are a group of bacteria commonly found in the environment, such as soil, water, and plants. Their presence in water indicates that the water has been exposed to sources that might also carry harmful germs, like fecal bacteria from humans or animals. While total coliforms themselves are not necessarily dangerous, they serve as an indicator that the water could be contaminated and may require further testing. Detecting total coliforms helps ensure water safety, as it prompts testing for more specific pathogens that could pose health risks.
