What is the minimum distance a decommissioned well should be from the edge of a drain field?

The minimum distance a decommissioned well should be from the edge of a drain field is critical for ensuring the safety and efficiency of both the septic system and the water supply. A distance of 50 feet serves as a widely accepted standard to prevent any potential contamination of the drinking water by effluent from the drain field. This buffer zone helps to protect the well from harmful bacteria, viruses, and nutrients that might leach from the septic system, thus maintaining groundwater quality.

In many jurisdictions, regulations are put in place to establish this distance to mitigate health risks associated with poor water quality. Standards such as these are grounded in scientific research and practical experience, emphasizing the necessity of distance in safeguarding water sources.

Other options, such as shorter distances like 10 feet or even a larger buffer like 100 feet, may not align with commonly accepted practices or regulations. A distance of 10 feet is typically too close to provide adequate protection, while 100 feet, while safer, is not usually mandated as a minimum and might be considered overly cautious in many areas.
