Absorption lines must be set back how far from wells or springs?

  1. 50 feet

  2. 75 feet

  3. 100 feet

  4. 120 feet

The correct answer is: 100 feet

Absorption lines, which are used for managing wastewater and spreading it into the ground, must be positioned a specific distance away from wells or springs to ensure that there is adequate protection of the water supply. The requirement of setting absorption lines back 100 feet from wells or springs is based on the goal of minimizing the risk of contamination. This distance helps to create a buffer zone that allows for natural filtration processes to occur within the soil, reducing the potential for pathogens or harmful substances to migrate into the water sources. This regulation is essential for safeguarding public health and maintaining water quality, particularly in residential areas where individual wells may be the primary source of drinking water. Establishing this distance is supported by various health and environmental guidelines that aim to protect potable water from potential pollutants originating from wastewater systems.
