What does the term "potable water" refer to?

The term "potable water" refers to water that is safe for human consumption. This definition signifies that the water has been treated and meets health standards, making it suitable for drinking, cooking, and other household uses. Ensuring that water is potable is crucial for public health, as it prevents waterborne diseases and promotes overall well-being.

The other choices do not accurately define potable water. Water used for irrigation, for instance, may not meet the health standards required for human consumption. Similarly, water found in rivers and lakes often contains natural contaminants and may require treatment before it is deemed safe to drink. Industrial process water may be clean but is typically not safe for human consumption as it can contain harmful chemicals and pollutants. Thus, the correct understanding of potable water emphasizes its suitability for human health and safety.
