What is "percolation testing" used for?

• A. To assess the age of a septic system
• B. To evaluate how quickly soil absorbs water for septic systems
• C. To determine the cost of a septic tank
• D. To inspect for pests in the soil

Answer: (B)

Percolation testing is specifically designed to evaluate how quickly soil absorbs water, which is a critical factor in the design and functionality of septic systems. This test involves digging test holes and monitoring the rate at which water drains through the soil. The results provide insight into the soil's capacity to treat and filter effluent from a septic system, ensuring that the system can function properly without causing surface water contamination or system failure. Understanding the percolation rate is vital for determining the appropriate size and type of septic system needed for a particular site, which contributes to effective waste management and environmental protection. Other choices, such as assessing the age of a septic system, determining costs, or inspecting for pests, do not relate to the primary function of percolation testing and are thus not relevant to this aspect of septic system evaluation.
