In Arizona, what is the required setback distance from a septic system to a water well?

In Arizona, the required setback distance from a septic system to a water well is 100 feet. This regulation is in place to protect the quality of drinking water from potential contamination that could occur from leaching or other issues associated with septic systems. Maintaining a distance of 100 feet ensures that any contaminants from the septic system have a reduced chance of reaching the well, thus safeguarding public health.

This distance is based on a combination of factors, including soil type, groundwater flow, and the potential for bacteria and other harmful substances to travel through soil and water. The 100-foot requirement is generally accepted as a standard by health departments to minimize the risks posed by septic systems to well water quality.

Understanding this setback distance is crucial for anyone involved in installing or maintaining septic systems and wells, as it helps to comply with local regulations and protect environmental health.
