What are the minimum dimensions for a concrete sealing block around a well?

• A. 2 feet in all directions, 4 inches thick
• B. 3 feet in all directions, 6 inches thick
• C. 4 feet in all directions, 5 inches thick
• D. 6 feet in all directions, 8 inches thick

Answer: (B)

The minimum dimensions for a concrete sealing block around a well are specifically designed to ensure both protection and structural integrity of the well. The requirement of 3 feet in all directions from the well and a thickness of 6 inches provides a solid foundation that effectively supports the well casing while preventing surface contaminants from entering the groundwater. The 3-foot radius is sufficient to create a buffer zone, which is critical for isolating the wellhead from nearby pollutants and ensuring that any surface runoff does not directly infiltrate into the well. Additionally, the thickness of 6 inches is robust enough to withstand environmental pressures, maintenance activities, and any potential settling that might occur over time. These specifications align with best practices in well construction and groundwater protection, ensuring the long-term safety and effectiveness of wells in providing clean water. The other options may not meet these essential requirements, which could lead to compromised well integrity and groundwater contamination.
