What is the minimum distance a public water well must be from soil absorption systems to ensure safety?

The minimum distance a public water well must be from soil absorption systems is 150 feet to ensure safety. This regulation is in place to prevent potential contamination of the water supply from effluent discharging from soil absorption systems.

Maintaining this distance helps to protect the well from pollutants that can leach into the groundwater from nearby septic systems or other absorption fields. The higher the distance, the more effective the natural filtration of the soil can be, which contributes to safeguarding the quality of the water supply.

This requirement is grounded in the understanding that soil can filter some contaminants effectively, but ensuring a greater distance enhances safety and reduces the risk of waterborne illnesses that could arise from drinking contaminated water.
