What is the minimum required distance a drain field must be from surface waters?

The minimum required distance a drain field must be from surface waters is established to protect water quality and prevent contamination. A distance of 100 feet is important because it helps to ensure adequate separation between the septic system and nearby bodies of water, such as rivers, lakes, or ponds. This distance allows for sufficient natural filtration of wastewater before it can potentially reach and impact these surface waters.

Maintaining a 100-foot buffer helps to mitigate the risk of pollutants entering the water, which is critical for protecting aquatic ecosystems and maintaining the safety of drinking water sources. It is also a regulation designed to comply with environmental health standards, reducing the likelihood of health risks associated with contaminated water.

Understanding this requirement is crucial for anyone involved in septic system installation and maintenance, as it reflects both public health concerns and environmental stewardship. A distance shorter than this could lead to regulatory violations and environmental degradation, while a greater distance ensures better protection for surface waters.
