For lined evapotranspiration beds, what is the required distance from pressure cemented wells?

The requirement for a 50-foot separation distance from pressure cemented wells to lined evapotranspiration beds is based on the need to protect groundwater resources and ensure the integrity of the well system. This distance helps to prevent potential contamination from the evapotranspiration process, which could introduce pollutants or pathogens into the groundwater supply should there be any failure or leakage in the systems.

Maintaining this separation distance is essential for safeguarding drinking water sources, particularly in areas where groundwater is a primary source of drinking water. The larger buffer zone of 50 feet provides an added layer of protection, as contaminants in the soil or water can take time to migrate and might be diluted or attenuated as they move through the subsurface environment.

The choices that suggest shorter distances or no required separation do not adhere to the standards or best practices outlined in regulations, which aim to minimize risk to public health and the environment. Therefore, establishing a minimum distance of 50 feet is crucial for ensuring compliance with regulatory requirements and protecting water quality.
