What is the minimum distance required between a septic tank and a water well?

The minimum distance required between a septic tank and a water well is established to protect the water supply from potential contamination. A separation of 100 feet is the standard in many regulations, including those pertinent to West Virginia, due to concerns about pathogens and pollutants that could leach from the septic system into the groundwater that supplies the well. This distance helps ensure that any effluent produced by the septic system does not travel directly to the water source, minimizing the risk of affecting the well water quality.

Maintaining this distance is crucial for public health and safety, as it helps mitigate the risk of exposure to harmful bacteria and chemicals that can arise from improper septic system functioning. While shorter distances may be permissible in some specific circumstances or locations depending on local regulations, a 100-foot buffer serves as a general rule to provide an adequate safeguard for the well water's integrity.
