fecal coliforms

Fecal coliforms are a group of bacteria found in human and animal waste. They serve as indicators of possible contamination by harmful pathogens in water sources. Their presence suggests that sewage or other waste may have entered the water, which can pose health risks. Testing for fecal coliforms helps determine water safety for drinking, recreation, and irrigation, guiding efforts to protect public health. While not all fecal coliforms are harmful themselves, their presence indicates conditions that could allow dangerous bacteria, viruses, or parasites to also be present.
