What is the distance requirement for public water wells from tanks in general?

The distance requirement for public water wells from tanks is typically established to prevent contamination of the water supply. Maintaining a distance of 10 feet is critical as it reduces the likelihood of contaminants from the tank, such as chemicals or waste, migrating into the well. This 10-foot buffer helps protect the public water supply and ensures that groundwater remains safe for consumption.

The other options present larger distances, which while they may seem beneficial for safety, are not the standard requirement set in many regulations. Water quality standards are based on significant research and assessments of potential risks, which establish the 10-foot separation as adequate to prevent contamination under normal circumstances. This standard helps ensure that public health is maintained while also considering practical aspects of construction and land use.
