What is the minimum distance an absorption field must be from a well?

The correct answer is based on health and safety regulations that govern the placement of septic systems and private wells. The minimum distance required between an absorption field and a well is specified to prevent contamination of the well water. With a distance of 100 feet, this standard allows for adequate filtration and reduction of pathogens or contaminants that might leach from the absorption field into the groundwater, which serves as the source for the well.

This regulation is essential in maintaining safe drinking water and protecting public health. Proper placement helps to ensure that the water extracted from the well remains uncontaminated and meets safety standards. This distance may vary by specific local regulations, but 100 feet is a common standard used in many areas due to its balance between safety and practicality in site development.

In contrast, the other options represent distances that may not sufficiently protect water quality. Distances shorter than 100 feet could increase the risk of contaminants reaching the well, potentially resulting in health hazards for users who rely on that well for drinking water. Thus, the choice of 100 feet reflects a guideline aimed at ensuring safe distances to protect groundwater from contamination emanating from septic systems.
