A soil percolation test, conducted at a specific location, determines the rate at which water is absorbed into the ground. This evaluation involves digging a hole, saturating it with water, and then measuring the time it takes for the water level to drop a defined amount. The resultant measurement, often expressed in minutes per inch, indicates the soil’s permeability.
The findings of this assessment are crucial for determining the suitability of a site for various applications, most notably septic systems. Proper soil permeability ensures the efficient and safe disposal of wastewater, preventing potential health hazards and environmental contamination. Historically, such evaluations were essential even before modern regulatory frameworks, as a practical means of ensuring basic sanitation in areas reliant on on-site wastewater treatment.
