Well Drillers Near Oak Creek, Wisconsin
Oak Creek region geology is dominated by thick clay and hardpan glacial tills over sand/gravel aquifers, with Silurian limestone/dolomite or deeper Cambrian/Ordovician bedrock (where drilled deep). Most residential wells are cased to sand/gravel or shallow dolomite. Typical flowing static water levels range 40–100 ft bgs and yield 5–30+ GPM.

Detailed Summary
A representative geologic profile for Oak Creek and adjacent areas indicates a surface layer of clay (sometimes with silt, brown/blue color, and/or hardpan) averaging 45–70 feet thick. This is underlain by sand, gravel, or sandy gravel units—commonly water-bearing—spanning 10–20 feet in thickness. In some locations, discontinuous clay or hardpan layers occur within or above the sand/gravel. Below 70–120 feet, Silurian or Ordovician limestone/dolomite is encountered. Deeper municipal or high-capacity wells may penetrate additional sequences of shale and dolomite, reaching several hundred to >1000 feet into Cambrian/Ordovician sandstones. Most residential wells with 5–15+ GPM yields are screened or open in the sand/gravel aquifers or upper dolomite, at total depths of 65–180 feet, with static water levels around 40–98 feet bgs.
Expected Geological Layers
| Depth (Feet) | Formation Type | Description | Characteristics |
|---|---|---|---|
| 0 – 50 ft | Clay (glacial till, silt, hardpan) | Brown, blue, grey clay; some with silt or hardpan. Occasional gravely or rocky inclusions. Non-caving to slightly caving. | Color: Brown/blue/grey Hardness: Soft to hard (hardpan layers present in some logs) |
| 50 – 70 ft | Sand and/or Sandy Gravel | Clean sand, sandy gravel, and occasional broken rock. Main aquifer zone for residential wells; highly permeable; water-bearing. | Color: Tan/yellow/grey Hardness: Loose to moderately compact |
| 70 – 100 ft | Sandy Gravel/Gravelly clay transition or occasional Hardpan | Transition zone between sand/gravel and underlying consolidated rock; possible clay/rock mix or hardpan. | Color: Variegated Hardness: Firm |
| 100 – 180 ft | Limestone/Dolomite (Silurian, Ordovician) | Grey to tan limestone or dolomite; fractured in places; yields water to some wells. May be absent in shallow-only wells. | Color: Grey/tan Hardness: Hard |
| 180 – 1500 ft | (Deep bedrock) Dolomites, Shales, and Cambro-Ordovician Sandstones | Units include (in order): deeper dolomites, local shales, and water-bearing sandstones (Tonti, Wonewoc, Eau Claire, Mount Simon) in wells >500 ft, only present in high capacity/municipal wells. | Color: Grey/tan/red Hardness: Very hard |
