Public water systems are required to compile a monthly report showing which of the following?

• A. average daily flow
• B. dates of dead-end flushing
• C. disinfection by-products
• D. number of customers

Answer: (B)

The main idea here is documenting distribution-system maintenance activities that directly affect water quality. Dead-end flushing is a targeted action used to remove stagnant water from parts of the distribution system where water doesn’t flow continuously. Recording the dates when these flushings occur provides regulators with a clear history showing that this maintenance is being performed regularly, and it helps ensure residual disinfectant levels and overall water quality are being maintained in the system. The monthly report serves as a traceable record of when flushing happened, which supports compliance and helps with scheduling and follow-up if issues arise. While average daily flow, the presence of disinfection by-products, and the number of customers are important data points, they are generally monitored or reported in other contexts or on different schedules. The specific monthly report in question is focused on maintenance actions that directly impact water quality in the distribution system, hence the emphasis on the dates of dead-end flushing.
