What is the required distance a septic tank absorption field must be from any lake, swamp, ditch, or water course?

The required distance for a septic tank absorption field from any lake, swamp, ditch, or watercourse is established primarily for environmental protection and to minimize the risk of contamination to surface water sources. A distance of 25-50 feet is necessary to ensure sufficient buffer space, allowing for the proper treatment of wastewater and reducing the likelihood of pollutants entering water bodies through surface runoff or groundwater flow.

This buffer zone is crucial because it helps to protect sensitive aquatic ecosystems from potential nutrient overloads and pathogens that can thrive in untreated wastes. Maintaining this distance not only safeguards public health but also aids in preserving the ecological balance of local water bodies.
