What is meant by potable water?

Potable water refers to water that is safe for human consumption, meaning it is free from impurities that could potentially harm health. This distinction is crucial because it encompasses not just the absence of harmful bacteria and pathogens, but also the levels of chemical contaminants that might be present in the water. The standards for potable water are set by health agencies and regulatory bodies to ensure that it meets safety criteria for drinking, cooking, and personal hygiene.

In contrast, water treated for irrigation purposes may not meet the same health standards, as it is primarily intended for agricultural use rather than human consumption. Additionally, water that is deemed only fit for industrial use may contain chemicals or pollutants that render it unsafe for drinking. Recycled water, while it can be treated to a level that makes it potable, is not inherently potable unless it has undergone the necessary purification processes. Therefore, the definition of potable water specifically highlights its suitability for consumption and safety for human health.
