What should the metal tags on potable water lines read based on the text?

SAFE DRINKING WATER
DRINKABLE
SAFE WATER
PURE WATER

The correct answer is: SAFE WATER

The metal tags on potable water lines should indicate "SAFE WATER" because this terminology clearly communicates that the water is suitable for drinking and safe for consumer use. Such labeling is crucial for ensuring public safety and compliance with regulations, as it provides immediate recognition of the water's quality and its intended use. While the other options also suggest quality drinking water, "SAFE WATER" is a widely recognized and standardized expression that best conveys the message of safety and potability in a concise manner. It emphasizes the safety aspect, which is essential in preventing confusion and promoting awareness about the water supply's integrity.
