A soil percolation test, often shortened to a “perc test,” is an evaluation of the soil’s water absorption rate. It involves digging holes in the area designated for a septic system’s drain field and observing how quickly water dissipates from those holes. The measurement is typically expressed as minutes per inch and indicates the soil’s capacity to drain effluent from a septic system.
This evaluation is a crucial step in determining if a plot of land is suitable for building a structure that relies on a septic system for wastewater management. It is essential for protecting public health and the environment by ensuring proper wastewater treatment and preventing contamination of groundwater. Historically, inadequate wastewater disposal has led to disease outbreaks and environmental damage, making this soil assessment a vital preventative measure.
