Which type of wells are used near the shore or river to obtain good-quality water?

• A. Deep wells
• B. Radial wells
• C. Pumped wells
• D. Shallow wells

Answer: (B)

Radial wells are designed specifically to draw water from an aquifer in a way that maximizes the area from which water is collected. They are often installed near the shore or rivers due to their ability to capture surface water that may be of good quality. By having a horizontal configuration, radial wells can utilize the natural flow of water towards the well, allowing for efficient extraction and reducing the risk of contamination from surface sources. Additionally, their design helps in reducing the drawdown in the aquifer and minimizes the risk of creating a cone of depression that could allow for contaminants to enter from nearby areas. This makes radial wells particularly beneficial when aiming to secure high-quality water while also mitigating risks associated with contamination close to shorelines or rivers. Other types of wells, such as deep wells or shallow wells, may not provide the same level of water quality or efficiency when located near a water body. Shallow wells can be more susceptible to contamination, while deep wells may not be viable options for accessing the upper layers of aquifers that are often closer to the surface, where higher quality water may be located. Pumped wells, while useful, may not have the specific design advantages that radial wells have in certain contexts.
