Which term describes wastewater that contains human waste?

• A. Black water
• B. Grey water
• C. Stormwater
• D. Industrial wastewater

Answer: (A)

Wastewater is categorized by what it contains. The term describing wastewater that contains human waste is black water, which includes toilet flush water and feces. Grey water, by contrast, comes from sinks, showers, and laundry and does not include fecal matter. Stormwater is rain runoff and isn’t sewage, while industrial wastewater comes from manufacturing processes and can contain various chemicals or pollutants. Because black water includes human waste and requires more extensive treatment, it is the correct description.
