What is the minimum separation distance between a water well and a building?

• A. 10 feet
• B. 5 feet
• C. 15 feet
• D. 25 feet

Answer: (A)

Keeping a water well a safe distance from a building helps protect the water you drink. If the well is too close, contaminants from plumbing leaks, spills, or other activities around the building can more easily reach the well through groundwater or surface water. The minimum separation commonly used is ten feet, which provides a practical balance between space for maintenance and a safer buffer against contamination. Distances shorter than that increase risk and may not meet code, while larger distances aren’t required for the basic protection. So the best answer is ten feet.
