Georgia Septic Installer Practice Test

What is the distance an absorption field should be installed from geothermal boreholes?

1. 25 feet

2. 40 feet

3. 50 feet

4. 75 feet

The correct answer is: 50 feet

The correct answer, 50 feet, reflects the necessary distance to ensure that the absorption field operates effectively while minimizing the risk of contamination from the geothermal boreholes. This distance is based on guidelines that aim to maintain the integrity of both systems, allowing for adequate spacing to prevent any interference in the subsurface flow of water and to maintain the performance of both the septic system and the geothermal system. Separation is crucial in this context as it helps to ensure that the effluent from the absorption field doesn’t impact the heat exchange process occurring in the geothermal system. This distance is designed to provide an effective buffer that allows for the proper functioning of both systems while avoiding any potential hydrological connections that might carry contaminants from the septic system into the geothermal boreholes. Regulatory guidelines often set these distances based on research into soil absorption rates, groundwater flow patterns, and potential health concerns. Adhering to this distance also mitigates risks associated with possible cross-contamination, providing safeguards for both the environment and public health.
