Which term describes water that is safe to drink and suitable for distribution?

• A. Potable water
• B. Brackish water
• C. Wastewater
• D. Non-potable water

Answer: (A)

This question tests understanding of water quality terms used in drinking water systems. Potable water is defined as water that is safe to drink and suitable for distribution to consumers, meeting the required health and quality standards. Brackish water is water with elevated salinity, not appropriate for drinking without treatment. Wastewater is used or contaminated water containing waste, typically not potable. Non-potable water is water not suitable for drinking, used for irrigation or industrial purposes. Therefore, the term that best describes water safe to drink and suitable for distribution is potable water.
