The Total Coliform Rule requires ________ sampling at each distribution sampling point.

Explanation:
Monthly sampling is required for each distribution sampling point under the Total Coliform Rule. This fixed cadence keeps a steady check on the distribution system for indicators of contamination, allowing timely follow-up if coliforms are detected. Weekly or quarterly sampling isn’t what the rule specifies, and saying it’s done “as per public health department” is not as precise as the mandated monthly schedule. If total coliforms are found, further actions, such as follow-up testing for E. coli, are triggered.
