A sanitary control easement must cover land within how many feet of a public water well?

A sanitary control easement is an essential aspect of protecting public water supplies, particularly around public water wells. The correct answer indicates that a sanitary control easement must cover land within 150 feet of a public water well. This distance is significant because it helps to prevent potential contamination of the water supply. By establishing a buffer zone of this size, it limits activities that could introduce pollutants into the well, thereby safeguarding the quality of the water being drawn for public use.

The 150-foot requirement is based on considerations of both health and safety, ensuring that areas which could potentially affect the water's quality are adequately monitored and controlled. This standard reflects best practices in water resource management and public health protection and is typically adopted in regulatory frameworks to promote clean and safe drinking water for the community.
