What is the minimum distance between a sewage tank and a well?

The minimum distance between a sewage tank and a well is crucial for ensuring safe drinking water and maintaining public health. The correct answer is 50 feet, as this distance is established to minimize the risk of contamination of the well water from the sewage system. This separation helps prevent the potential migration of harmful pathogens and chemicals from the sewage tank into the groundwater that feeds a well, thus protecting the quality of the drinking water.

Additionally, local regulations may specify this distance based on hydrological studies and the type of soil in the area, but 50 feet is a widely accepted standard in many states, including Connecticut. Other distances, such as 75 feet, 100 feet, or 30 feet, either do not provide the same level of safety or may be insufficient to prevent contamination, which is why they are not considered the minimum requirement. Maintaining this distance is vital for safeguarding public health and ensuring that water supply remains uncontaminated.
