Which practice is a method of ensuring well sanitation/safety?

• A. Sealing abandoned wells
• B. Painting the outside of the well casing
• C. Installing a wind turbine near the well
• D. Planting trees near the well

Answer: (A)

Sealing abandoned wells blocks pathways that connect surface conditions to the groundwater and removes a surface-access hazard. When a well is left open, rain and surface water can carry contaminants down into the aquifer, animals or insects can enter the well, and the structure can deteriorate, creating safety risks. Sealing it with a proper grout or cement plug and a protective cap creates a secure, watertight barrier, preventing contamination and reducing the chance of injury. The other options don’t address sanitation or safety: painting the outside is cosmetic, a wind turbine near the well isn’t related to well safety, and planting trees can alter drainage or damage the well rather than protect it.
