Which term describes water that is safe for human consumption?

• A. Potable Water
• B. Distilled Water
• C. Rainwater
• D. Gray Water

Answer: (A)

Potable water is water that is safe to drink. It has been treated to remove harmful organisms and chemicals and meets drinking-water quality standards, so it can be used as a source for human consumption.

Distilled water is simply water that has been purified by boiling and recondensing; it’s safe to drink but the word describes a purification method, not the general standard for everyday drinking water. Rainwater can be clean, but it isn’t automatically safe to drink without treatment because it may carry pollutants from the air or surfaces it’s touched. Gray water comes from sinks, showers, and washing machines and is not suitable for drinking; it’s typically reused for non-potable uses after proper treatment.

So, the term that directly means water safe for human consumption is potable water.
