What is the minimum setback distance for a septic tank from a proposed or existing well?

The minimum setback distance for a septic tank from a proposed or existing well is critical in ensuring water quality and public health. This distance is established to prevent contamination of the well water, which could occur from the leachate produced by the septic system. A distance of 50 feet provides a safeguard against the potential pathways of pollutants, such as bacteria and nitrogen, which could migrate from the septic tank to the well.

This setback requirement is determined by health and safety regulations, which take into account factors such as soil permeability, groundwater flow, and the nature of septic system operations. By maintaining this 50-foot separation, the risk of compromising the drinking water supply is significantly reduced, thereby contributing to public health and safety.

Other options, such as 25 feet or 10 feet, do not provide adequate protection, as contaminants could more easily reach the well water within these shorter distances. The importance of every setback requirement lies in the objective of protecting well water quality and the health of individuals using that water.
