What defines potable water?

Potable water is defined as water that is free from harmful impurities, making it safe for human consumption. This definition encompasses several key aspects, including the absence of pathogens, chemical contaminants, and other hazardous substances that could pose health risks. The quality of potable water is regulated to ensure it meets safety standards set by health authorities, which help protect public health by preventing waterborne diseases.

While options related to taste, aesthetics, and availability might contribute to a person's perception of water quality, they do not address the critical health implications of water safety. For instance, water could taste pleasant or look clear, but if it contains harmful bacteria or contaminants, it would not be considered potable. The focus on harmful impurities underscores the importance of assessing water safety based on scientific and health-related criteria rather than subjective characteristics.
