Which item is an example of gray water?

• A. Urine
• B. Boxes
• C. Bath water
• D. Blood/bodily fluids

Answer: (C)

Gray water is wastewater from non-toilet sources such as baths, showers, sinks, and laundry. It contains soaps, oils, and skin debris but does not include toilet waste. Bath water fits as gray water because it’s used wash water from bathing, not toilet waste. Urine, while waste, is typically treated as a separate stream rather than gray water, and blood or other bodily fluids are hazardous medical waste, not gray water. Boxes are solid material, not wastewater.
