Which of the following is an example of clear water waste?

Cooling water is classified as an example of clear water waste because it typically does not contain significant contaminants or harmful pollutants. This type of water is usually generated from processes such as industrial cooling systems, air conditioning units, or power generation plants, where it is used to absorb heat and is then discharged back into the environment or a treatment facility without having been contaminated by harmful substances.

The other types of water mentioned in the choices may carry more pollutants or organic material. For instance, cooking water may contain leftover food particles or grease, and cleaning water often includes detergents or cleaning agents that could pose environmental concerns. Sewage water is highly contaminated, containing a multitude of pathogens, organic matter, and chemicals. Thus, cooling water stands out as the least contaminated among these options, making it fit within the definition of clear water waste.
