One key part of any site evaluation for location of a soil treatment area is the description of the soil profile. As we have stated many times, when we troubleshoot systems that are experiencing problems or have failed, the most frequent reason is a misinterpretation of the soil characteristics. There are two primary areas where mistakes occur: evaluation of structure and texture to estimate the long-term acceptance rate (LTAR) and not identifying features in the soil that indicate periodic soils saturation.
Soil characteristics used as evidence of periodic or seasonal saturation of soil layers are called redoximorphic features. These features are
