What triggers a violation notice in drinking water regulations?

• A. Single positive test for microorganisms
• B. Three repeat tests for E. coli
• C. Presence of total coliform
• D. General water quality assessment

Answer: (C)

A violation notice in drinking water regulations is triggered by the presence of total coliforms. Total coliforms are a group of bacteria found in the environment and in the intestines of warm-blooded animals. The detection of total coliforms in drinking water suggests that there may be a pathway for pathogens to enter the water supply, indicating potential contamination. Regulatory agencies set standards for acceptable levels of these bacteria because they serve as indicators of water quality and safety. When total coliforms are detected in a water sample, it necessitates further investigation, including more rigorous testing for specific harmful microorganisms such as E. coli, as well as actions to address and remediate the contamination source. Thus, the presence of total coliforms signifies a significant concern for public health and leads to the issuance of a violation notice to ensure that water utilities take appropriate corrective measures.
