What is an objective of a percolation test?

The objective of a percolation test is to determine the drainage properties of soil. This test is crucial in the design and installation of On-Site Sewage Facilities (OSSF) as it provides essential information about how quickly water can move through the soil. The rate of percolation affects the sizing of the septic system's drain field and overall functionality. If the soil drains too quickly or too slowly, it may not properly treat wastewater, leading to system failures and environmental issues.

While assessing the structural integrity of the OSSF and evaluating the health of nearby water sources are important considerations in the overall management of on-site sewage systems, they do not directly relate to the specific purpose of a percolation test. Similarly, measuring the depth of groundwater is not the primary focus of this test, as it is more concerned with how well the soil can absorb and filter the effluent from the sewage system. Understanding the drainage properties ensures that the system is designed to effectively handle wastewater, thus protecting both public health and the environment.
