What does the term “potable water” refer to?

The term “potable water” specifically refers to water that is safe for human consumption and suitable for use in food preparation. It must meet certain health and safety standards set by regulatory bodies to ensure that it does not pose any health risks to individuals. This includes being free from harmful contaminants and pathogens.

In contrast, bottled water while often potable, is not defined as such solely because it is bottled and sold. Water used for irrigation may not be treated to the same standards and could contain pathogens or pollutants that make it unsafe for consumption. Non-treated water from natural sources may also contain contaminants or pollutants, making it unsuitable for drinking without proper treatment. Thus, the focus on safety and applicability for human consumption is what distinctly qualifies "potable water."
