Which characteristic defines potable water?

Potable water is defined as water that is safe for human consumption. This means it must meet health standards that ensure it is free from harmful contaminants, including pathogens, chemicals, and other substances that could pose risks to health. Regulations set by organizations such as the Environmental Protection Agency (EPA) in the United States outline the permissible levels of various contaminants in drinking water. While factors like clarity, mineral content, and pH levels can influence water quality, they are not definitive indicators of potability. For instance, water can appear clear but still contain harmful microbes or chemicals. Therefore, the key characteristic that distinguishes potable water is its safety for consumption, making it suitable for drinking and preparing food.
