Soils are assigned to 4 hydrologic groups and 3 dual groups. Group A - high infiltration rate when wet, low runoff potential. Group B - moderate infiltration, low runoff potential. Group C - slow infiltration, higher runoff potential. Group D - very slow infiltration rate, highest runoff potential. The dual groups are A/D, B/D, and C/D. These are used for certain wet soils that can be adequately drained. The leading letter refers to the drained condition and the second letter is
