What is the required separation distance between public water wells and unlined evaporation beds?

The required separation distance between public water wells and unlined evaporation beds is set at 150 feet to protect the water supply from potential contamination. Public water wells are critical sources of drinking water, and maintaining this distance helps ensure that contaminants from the evaporation beds, which can include various pollutants that may leach into groundwater, do not reach the wells.

This requirement is part of groundwater protection regulations, which aim to maintain the safety and quality of drinking water supplies for the public. The 150-foot separation acts as a buffer zone, minimizing the risk of harmful substances from the evaporation beds infiltrating the well's source area and compromising water quality.

Other separation distances, such as 100 feet, 75 feet, or 50 feet, may be applicable in different contexts or for different types of sites but do not meet the safety standards established for public water wells in proximity to unlined evaporation beds. Thus, the 150-foot distance is crucial for safeguarding drinking water and complying with health and environmental regulations.
