What is the soil like in Perry County for installing subsurface lateral fields?
Perry County soil in general has a fairly high percentage of clay. Very claylike soil does not absorb water very well; therefore subsurface systems tend not to work well in Perry County or in Southern Illinois for that matter. On average 80-90% of the systems installed in Perry County are aeration units. Now that is not to say that subsurface systems do not work at all. There are some areas of soil in the county that may absorb water fairly well, but are much rarer than areas of high clay content.
