What is the recommended depth for a dug well?

• A. 10 feet
• B. 20 feet
• C. 30 feet
• D. 40 feet

Answer: (B)

The recommended depth for a dug well typically falls around 20 feet. This depth is considered effective because it usually allows the well to access the groundwater, which is generally found at this level in many regions. Additionally, being at this depth helps ensure that the water is less prone to contamination from surface sources, as it is deep enough to provide a buffer from pollutants that can seep from the surface down to the water table. While dug wells can sometimes be deeper or shallower depending on local geological conditions, 20 feet is a commonly accepted standard that balances accessibility to water while minimizing the risk of contamination.
