Columbus, MI48063
Typical Columbus area (St. Clair/Macomb counties) residential well penetrates layered glacial sediments - mostly clay, sand, and occasional gravel, overlying deeper water-bearing sand or gravel, with some bedrock (sandstone/shale) at depth in places.

Recommended Method
A representative geology profile for the Columbus region, based on synthesis of several recent well logs, reveals the uppermost layer is usually a thin soil/sand interval, followed by thick sequences of yellow/gray/blue clay or clay-mixed with sand and gravel. Persistent, productive water-bearing aquifers are typically found in lower sand/gravel zones below 70-120 feet, with the base of logs sometimes reaching into consolidated bedrock (sandstone/shale) below 110-130 feet. Wells are typically cased with 4-5 inch PVC or steel to 100-120 feet, grouted with bentonite or cement, and completed in water-bearing sand/gravel zones. Typical static water levels range 10-40 feet below grade. A standard residential (5-15+ GPM) well is commonly completed between 90 and 130 feet. High-capacity wells may be deeper, but household supply is reliably found before 130-145 feet.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 1 ft | Topsoil/Sand | Thin topsoil or fine sand | Color: Brown/Yellow Hardness: Soft |
1 – 20 ft | Clay (Yellow/Gray/Blue) | Dense, often plastic clay, occasionally with minor sand or gravel lenses | Color: Yellow, Gray, Blue Hardness: Soft to Firm |
20 – 80 ft | Clay with Sand/Gravel | Thicker heterogeneous zone of clay interbedded with sand and gravel, some layers water-retentive | Color: Gray/Yellow Hardness: Firm |
80 – 115 ft | Sand/Gravel (Water-Bearing) | Coarse sand and/or gravel with high permeability, main aquifer zone for residential wells | Color: Gray/Yellow Hardness: Loose to Medium |
115 – 140 ft | Clay, Shale, or Sandstone (locally) | Locally encountered bedrock (shale/sandstone) or dense clay - less productive, sometimes forms well base | Color: Dark Gray, Brown, Greenish Hardness: Medium to Hard |
