Understanding total coliforms

Total coliforms are a key microbiological indicator used to assess the overall sanitary quality of water in drinking, industrial, and environmental systems. While not all coliforms are harmful, their presence can indicate potential contamination from sewage ingress, untreated water, or compromised system hygiene controls. Routine testing for total coliforms plays a vital role in assessing water safety and meeting the requirements of the Private Water Supplies Regulations and the Water Supply (Water Quality) Regulations.
