What is non-portable water?

Non-potable water refers to water that is not safe for human consumption. It may contain harmful microorganisms, pollutants, or chemicals that can pose health risks if ingested. Understanding the distinction between potable (safe) and non-potable (unsafe) water is critical, especially in military settings where access to clean drinking water is vital for maintaining health and preventing disease in the field.

The options related to safe drinking water—such as water that is bottled for sale or from municipal supplies—are generally intended for human consumption and thus would be classified as potable. Water from untreated sources can often be non-potable, but without context or specific information about those sources, it cannot be assumed to be unsafe. Conversely, the definition of non-portable water emphasizes its unsuitability for drinking, highlighting the importance of ensuring that water sources are properly treated and tested before use in any capacity that may affect health.
