What is the required distance from wells and underground cisterns to lined evapotranspiration beds?

The required distance from wells and underground cisterns to lined evapotranspiration beds is established to ensure that any potential contaminants do not threaten the water supply. A distance of 50 feet is typically specified in regulations to maintain a safe buffer. This separation distance helps protect the quality of groundwater by minimizing the risk of leachate from the evapotranspiration beds reaching the well or cistern.

In many regulatory contexts, distances like 20 feet, 100 feet, or 200 feet may not adequately balance the need for proper wastewater management with the protection of drinking water sources. Distances that are too short would not provide sufficient protection, while distances that are excessively long might impose unnecessary restrictions on land use without corresponding benefits. Hence, the 50-foot requirement is a compromise designed to provide both safety and practicality in wastewater management practices.
