What is an acceptable distance for public water supply lines from lined evapotranspiration beds according to health guidelines?

The acceptable distance for public water supply lines from lined evapotranspiration beds is 10 feet, which aligns with health guidelines aimed at protecting water quality. This distance is established to ensure that potential contaminants, which could be present in the vicinity of evaporation and transpiration processes, do not have a chance to infiltrate or impact the public water supply.

Maintaining a buffer zone of this size is a preventative measure that acknowledges the possibilities of groundwater contamination and leaching, ensuring the safety and sanitation of drinking water. This safety margin helps safeguard human health by reducing the risk of exposure to pathogens or pollutants that could migrate from the evapotranspiration beds to the water supply network.

In contrast, the other distance options are insufficient as they do not provide the same level of protection, which is why they do not meet health guidelines.
