Which urban problem is most directly associated with polluted water when sewage treatment is inadequate?

• A. Air Pollution
• B. Noise Pollution
• C. Water Pollution
• D. Sprawl

Answer: (C)

Inadequate sewage treatment directly affects water quality, showing how sanitation practices link to water pollution. When wastewater isn’t properly treated, contaminants—pathogens, nutrients, and chemical pollutants—flow into nearby rivers, lakes, and groundwater. This contamination makes water unsafe for drinking and recreation, harms aquatic life, and can trigger problems like algal blooms and oxygen depletion in urban waterways. Air pollution would come from emissions to the air, not from wastewater in the water; noise pollution concerns sound levels rather than water quality; sprawl describes the spread of development and isn’t a direct result of sewage treatment issues. Because the primary consequence of poor sewage treatment is polluted water, this is the best answer.
