What is the required minimum clearance between a septic tank and a private water well?

The required minimum clearance between a septic tank and a private water well is 50 feet. This distance is critical for protecting the water supply from potential contamination that could arise from septic system failures or leaking wastewater. Having a buffer zone helps ensure that harmful pathogens, nutrients, and other pollutants do not travel from the septic system to the well water, thereby safeguarding public health.

This standard reflects best practices in sanitation and public health protection, as it mitigates risks associated with groundwater pollution. A distance of 50 feet is seen as an effective compromise that balances practicality in installation with the necessary precautions to protect water sources. Additionally, local regulations and guidelines may also stipulate this distance to maintain the integrity of water supplies in residential areas and prevent potential health hazards related to contaminated drinking water.
