What does the term "potable water" refer to?

The term "potable water" specifically refers to water that is safe for human consumption. This means that it meets health standards and is free from harmful contaminants that could pose a risk to health when ingested. Potable water is treated and tested to ensure it is suitable for drinking and cooking, thus making it essential for public health.

In contrast, water used for irrigation is not necessarily safe for drinking and may contain chemicals or pathogens that can be harmful if consumed. Chemically treated water can refer to various types of water, some of which may not be safe for consumption, depending on the nature of the treatment and the substances involved. Water used for industrial purposes is typically not intended for human consumption and may contain pollutants or chemicals that make it unsafe for drinking.
