What is the minimum distance a septic tank absorption field should be from any well?

The minimum distance a septic tank absorption field should be from any well is 100 feet. This regulation is in place to ensure the safety of drinking water supplies and to prevent potential contamination. The separation distance is based on the understanding that groundwater can carry pathogens and chemicals from the septic system, which could lead to health risks if they migrate into the water supply accessed by the well.

Maintaining a distance of 100 feet helps to provide a buffer zone that significantly reduces the risk of contaminants reaching the well. This standard is aligned with guidelines from public health authorities aimed at protecting human health and ensuring the safe use of groundwater resources. Variations in soil conditions, drainage patterns, and local regulations might influence this distance in certain areas, but the general recommendation of 100 feet serves as a best practice to safeguard water quality.
