What is a well casing?

• A. A filter used to purify water
• B. A pump system for groundwater extraction
• C. A concrete area around the well to prevent contamination
• D. An underground storage for well water

Answer: (C)

A well casing is a crucial component of a well that serves to protect the integrity of the water supply. It typically refers to the tube or lining that is installed in the borehole after drilling to prevent the well from collapsing and to protect the groundwater from surface contaminants. The casing also minimizes the risk of contaminants entering the groundwater supply from the surrounding soil and surface runoff, ensuring that the water remains clean and safe for consumption. By providing a sealed boundary, well casing plays an essential role in safeguarding the water source, making it less vulnerable to pollution. Proper installation of well casing is vital for maintaining water quality and ensuring that the well functions effectively over its operational lifespan.
