The choice of potable drinking water is an example of a non-wastewater source as it refers to water that is treated and safe for human consumption. Unlike the other options listed, which are all types of water that may carry pollutants and lead to contamination of water systems, potable water is specifically designed for direct use without treatment.

Agricultural runoff, stormwater, and industrial discharge are all considered sources of wastewater because they can contain contaminants from various activities, including farming, urban runoff, and industrial processes. These types of water often require treatment before they can be safely returned to the environment or reused, distinguishing them from potable drinking water.
