What prevents run-off water from contaminating a well?

• A. Well cap
• B. Gravel filter
• C. Concrete casing
• D. Surface drainage system

Answer: (A)

A well cap is an essential component that helps prevent run-off water from contaminating a well. The primary function of a well cap is to seal the top of the well casing, which effectively keeps out surface water, debris, and animals that may introduce contaminants. Properly installed well caps are designed to create a barrier, ensuring that only clean water enters the well while preventing contaminants from the surface from infiltrating it. In scenarios where surface water contains pollutants, such as fertilizers or waste, a well cap is a critical line of defense as it protects the water supply from potential contamination. The seal must be watertight and secure to provide the highest level of protection. Proper maintenance and regular inspections of the well cap can ensure that this barrier remains effective over time.
