What is the minimum setback distance for wells from septic tanks when the tank has a capacity greater than 2000 gpd?

The minimum setback distance for wells from septic tanks with a capacity greater than 2000 gallons per day is 200 feet. This requirement is established to protect groundwater sources from potential contamination that can occur when waste from septic systems seeps into the soil and impacts nearby wells. The larger the septic tank capacity, the greater the potential for contaminants to spread, necessitating a larger buffer zone to ensure safe drinking water.

Setting the setback distance at 200 feet strikes a balance between practical implementation and public health safety, as it helps to reduce the risk of harmful microorganisms and chemicals from septic systems affecting well water quality. Ensuring this distance is maintained is crucial for the protection of drinking water supplies, especially in areas where groundwater is a primary source of drinking water.
