Soil Perc Testing 101

Soil naturally treats and degrades organic matter, destroys pathogens, and acts as a filter to remove contaminants from water. Because the soil plays such an important role it’s vital to ensure the selected site can properly handle the water from the distribution laterals.First, the basics. The ideal slope for a soil absorption area is between 2 and 15 percent. In some areas a slope of 15 to 30 percent is provisionally acceptable. Soil texture, depth to seasonally high water table, depth to bedrock and depth to restrictive clay layers should all be considered when determining lateral location.These soil characteristics help
