Question

What major public health problem is directly mitigated by preventing the open accumulation and stagnation of untreated grey water in rural residential areas?

• A. Malnutrition due to lack of sanitation infrastructure
• B. Spread of non-communicable diseases from contaminated water sources
• C. Vector-borne diseases (e.g., mosquito breeding)
• D. Increased rates of respiratory illnesses due to poor air quality

Answer 1

Answer:

C. Vector-borne diseases (e.g., mosquito breeding)

• Stagnant water provides a breeding ground for vectors like mosquitoes (responsible for Dengue, Malaria, etc.).

• Effective GWM, by soaking water underground or routing it for treatment/reuse, eliminates this health hazard.
