The professional soil scientists at Soil Solutions are dedicated to providing soil services in the areas of the commercial and residential soil testing for septic systems, septic system design, hydric soil mapping, percolation test analysis and soil classification.
Soil mapping is the process of determining the soil types or other properties of the soil cover over a landscape. The soils are then mapped for others to understand and design uses for the land. Soil mapping applies the principles of soil science and draws heavily from geomorphology theories of soil formation, physical geography, and analysis of vegetation and land-use patterns. Primary data for the soil survey are acquired by field sampling and supported by remote sensing.
A percolation test (a perc test) is used to determine the absorption rate of soil for a septic drain field or "leach field." The results of a percolation test are required to properly design a septic system. Simply stated, percolation testing is simply observing how quickly a known volume of water dissipates into the subsoil of a drilled hole of known surface area. While every county will have its own laws regarding the exact calculations for the length of line, depth of pit, etc., the testing procedures are exactly the same.
