Which term describes water that is suitable for human consumption?

The term that describes water suitable for human consumption is "potable water." This designation indicates that the water meets specific health and safety standards set by regulatory agencies, ensuring that it is safe to drink and does not pose a risk to health. Potable water is treated and tested to remove harmful contaminants and pathogens, making it fit for human use.

Purified water refers to water that has undergone a purification process, which can enhance its quality, but this does not necessarily mean it is potable if it hasn't met the required standards for safety. Filtered water typically indicates that the water has been passed through a filter to remove certain impurities, but again, it may not be deemed fully safe for consumption without further testing. Natural water often refers to water from natural sources, such as rivers or springs, which may not be safe to drink without treatment.

Overall, "potable water" is the most comprehensive and accurate term when referring to water that is safe for human consumption.
