1. 30 feet

2. 50 feet

3. 70 feet

4. 100 feet

The correct answer is: 50 feet

The minimum setback distance for a septic tank from a well or spring is 50 feet. This distance is established to ensure the safety and quality of drinking water. A setback is crucial because it reduces the risk of contaminants from the septic system seeping into groundwater or directly affecting the water source. This standard distance is designed to provide a buffer zone that minimizes the potential for microbial or chemical pollutants to enter the well or spring, which is especially important in areas where groundwater is used for drinking purposes. The requirement of 50 feet is based on various health and environmental considerations, including the permeability of the soil, the type of septic system used, and the local regulations that govern water quality. Maintaining this distance helps to protect human health and the environment, ensuring that the water supply remains uncontaminated.
