Analysis of representative well logs from the Kawkawlin region indicates a prevalent geological sequence starting with surficial topsoil (present but usually less than 3 feet thick), followed by an extensive clay (sometimes interbedded with hardpan or silt) layer. This is typically underlain by mixed sand, gravel, and stony material, often marking the primary water-bearing zones for high-yield residential wells. Below these unconsolidated sediments, wells encounter various consolidated formations such as hardpan, shale (black, gray, or mixed), and alternating bands of sandstone (occasionally limestone). Bedrock aquifers, especially sandstone and shale, provide reliable water at greater depths. Typical residential wells (5-15+ GPM) are completed in the sand/gravel or upper consolidated zone (sandstone/shale), requiring total depths of 120 to 165 ft. For higher capacity wells, drilling to 200–225+ ft is common.
| Depth (Feet) | Formation Type | Description | Characteristics |
|---|---|---|---|
| 0 – 2 ft | Topsoil | Organic-rich surficial material | Color: Brown/Black Hardness: Soft |
| 2 – 60 ft | Clay (with possible hardpan bands) | Predominantly clay, sometimes interbedded with hardpan, blue/yellow clay or stones | Color: Blue, yellow, or gray Hardness: Medium. |
| 60 – 120 ft | Sand, Gravel, and Stony Hardpan | Sand and gravel, often stony or with zones of hardpan | Color: Yellow/brown/gray Hardness: Medium-Firm |
| 120 – 150 ft | Clay/Sand/Gravel transition or consolidated hardpan | Transition zone, may include mixed sand, gravel and clay or hardpan | Color: Gray/brown Hardness: Firm-Hard |
| 150 – 225 ft | Shale & Sandstone (occasionally with limestone) | Alternating beds of shale and sandstone, sometimes with limestone in places | Color: Gray, black, white (shale); tan/yellow (sandstone); gray (limestone) Hardness: Hard |
| 225 – 370 ft | Shale (thick) and Lower Sandstone | Thick sequence of shale, underlain by basal sandstone (possibly aquifer for deep, high-capacity wells) | Color: Gray, black (shale); tan (sandstone) Hardness: Hard |
