What is confirmed through potable water logs?

The potable water logs serve as a vital record in ensuring the safety and quality of drinking water on navy ships. Through these logs, weekly coliform bacteria testing is confirmed, which is crucial in monitoring the microbial quality of the water supply. Coliform bacteria are indicators of potential contamination, and regular testing helps ensure that the water is safe for consumption. This process allows for timely identification of any issues, contributing to the health and safety of all personnel on board.

While daily temperature readings, monthly tank cleaning schedules, and annual plumbing inspections are also important aspects of maintaining potable water systems, they are not specifically confirmed through the potable water logs. These logs primarily focus on testing results and the overall microbiological status of the water, which is why weekly coliform bacteria testing is the correct confirmation within this context.
