1. 0 feet

2. 5 feet

3. 10 feet

4. 20 feet

The correct answer is: 10 feet

The minimum required distance for a septic tank from an absorption field when considering a water supply line is 10 feet. This distance is established to ensure safety and prevent contamination of potable water supplies. By maintaining this separation, it reduces the risk of microbial contamination and ensures that any potential effluent from the septic system does not adversely impact the water supply. Septic systems are designed to filter and treat wastewater, but there can still be instances where contaminants might escape or migrate through the soil, especially during periods of heavy rainfall or system failure. The established distance acts as a buffer zone, providing additional protection for water supply lines and safeguarding public health. This specific measurement aligns with guidelines set by health departments and environmental agencies, which prioritize the protection of drinking water sources from potential pollutants stemming from septic systems.
