Where should one of the soil borings be located?

• A. At the highest elevation of the system
• B. At the entry point of the septic tank
• C. At the lowest elevation of the subsurface seepage system
• D. At the midpoint of the system

Answer: (C)

Locating one of the soil borings at the lowest elevation of the subsurface seepage system provides crucial information about the soil's drainage characteristics and groundwater conditions. This position is strategic because it helps assess how the septic system interacts with groundwater and how effectively effluent will be absorbed and filtered by the soil. By examining the soil at this depth, a contractor can evaluate the potential for saturation, which is essential for understanding the performance and potential issues of the sewage treatment system. Soil conditions at the lowest elevation can indicate whether there is sufficient percolation and absorption, which directly impacts the system's overall functionality and effectiveness.
