Good to Fair; wet soil conditions MAHONING | Not suitable | Difficult to work soil when wet. POOR. | Fair stability and compaction; slow seepage; moderate shrink- swell; difficult to work with soil material when wet; good piping resistance. | Seasonal high water table; slow seepage rate; usually suitable for dug ponds on level topography. | Severe: high water table and moderate shrink- swell; high compressibility. |
Fair; hazard of excavation | Not suitable | Poor: difficult to work clay- like soil when wet. | Fair to good stability; slow permeability when compacted; clay-like material is hard to work when wet; may be used for impervious cores. | Seasonal high water table; slow seepage rate; normally suitable for dug ponds. | Severe: high water table; moderate shrink- swell; compressible. . |
