What is the minimum distance for septic tanks from the water supply?

The requirement for the minimum distance from septic tanks to a water supply source is based on protecting the water supply from potential contamination. A distance of 100 feet is mandated to help ensure that any effluent or seepage from the septic system does not reach the water supply, thus safeguarding the health and safety of the users relying on that supply. This regulation is critical because septic systems can potentially release pathogens and nutrients that could pollute groundwater or surface water, leading to hazardous conditions.

In addition, this minimum distance takes into account various environmental factors, such as soil type, elevation, and drainage patterns, which might affect how quickly contaminants could travel through the environment. Adhering to this distance plays a vital role in maintaining safe drinking water standards and reducing the risk of waterborne diseases.

The other distances provided do not meet the recommended safety standards to effectively protect the water supply, illustrating why 100 feet is the established guideline.
