What is the minimum distance a well should be from a septic system?

The minimum distance a well should be from a septic system is established to protect the water quality of the well. A separation of 100 feet is commonly recommended because it helps to prevent the contamination of the groundwater that the well utilizes, which can occur due to pathogens, nitrates, and other contaminants that may leach from the septic system. This distance is designed to provide an adequate buffer, allowing for natural filtration and reducing the risk of pollutants entering the well.

Local health departments and regulations might specify this distance to enhance public health safety. Less distance could increase the likelihood of contamination from potential failures in the septic system or from daily usage impacts. Therefore, maintaining a 100-foot separation is a standard practice to ensure safe drinking water and minimize health risks associated with septic system failures.
