A representative geological profile for residential wells in the Lawton, MI region, based on synthesis of sampled well logs, shows an upper sequence of mixed clay, silt, and gravel (including yellow/brown clay and gravel, sometimes topsoil), typically 5-15 feet thick. This is commonly underlain by alternating layers of sand, silty clay, and gravel, with clay-rich horizons periodically separating water-bearing sandy units. The most productive and frequent aquifer intervals are medium to coarse sand or sand/gravel units found at depths between 20 and 120 feet, often interbedded or capped by clay. Groundwater tables typically occur between 10 and 56 feet below grade, and residential wells are most reliably completed at 60-100 feet for yields over 10 GPM, with high-capacity wells reaching depths up to 110-120 feet.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 2 ft | Topsoil/Clay/Gravel | Thin surficial topsoil or yellow/brown clay and gravel, sometimes with minor silt | Color: Yellow/Brown/Tan Hardness: Soft to firm |
2 – 10 ft | Clay & Gravel | Variable mix of clay, sand, and gravel, low permeability, sometimes with thin clay lenses | Color: Brown/Yellow/Tan/Gray Hardness: Firm |
10 – 35 ft | Sand/Gravel | Fine to medium sand, sometimes intermixed with gravel or occasional clay layers | Color: Brown/Tan Hardness: Loose to medium |
35 – 55 ft | Clay (with some gravel/sand) | Predominantly clay or silty clay, may contain thin sand or gravel beds, can act as aquitard | Color: Gray/Tan Hardness: Firm to stiff |
55 – 88 ft | Sand (water bearing) | Fine to medium sand, typically main aquifer, sometimes interbedded with minor clay or gravel | Color: Tan/Gray Hardness: Loose to medium |
88 – 116 ft | Sand (coarser/deeper) | Medium to coarse sand or sand & gravel with high yields, sometimes with minor clay | Color: Tan/Gray Hardness: Loose |
116 – 117 ft | Clay | Thin clay horizon, locally present at base of typical well depth in deepest sampled wells | Color: Brown/Tan/Gray Hardness: Stiff |
