What is the definition of potable water?

The correct answer defines potable water as water that meets U.S. public health standards. This means that the water is safe for human consumption and is free from harmful contaminants that could pose health risks. The public health standards are established by various regulatory agencies, including the Environmental Protection Agency (EPA), ensuring that drinking water is treated and tested to protect public health.

In contrast, the other options do not accurately define potable water. Simply being treated with chemicals does not guarantee that the water is safe to drink, as the nature of the chemicals and the treatment process play crucial roles in determining water safety. Water taken from natural springs may be clean, but it is not automatically considered potable unless it meets specific safety standards. Lastly, water stored for industrial use may not be safe for human consumption, as it could be contaminated or unsuitable for drinking, depending on its intended purpose and treatment.
