For water to be classified as potable, it is essential that it does not contain objectionable pollution or infectious agents. This characteristic ensures that the water is safe for human consumption and does not pose health risks. Potable water must be free from contaminants that can lead to illness or disease, such as bacteria, viruses, chemicals, or harmful pollutants. The focus on safety and cleanliness is paramount in determining whether water is fit for drinking.

While factors like taste, clarity, and mineral content can influence the perception of water quality, they do not define potability in the same way that the absence of harmful contaminants does. For instance, water may taste pleasant or be visually appealing but still contain dangerous pathogens or pollutants, rendering it unsafe to consume. Thus, the defining characteristic of potable water primarily revolves around its safety and the absence of objectionable components.
