Recommended Method
The representative geological profile for the Danbury, WI area, synthesized from a sample of well logs, shows a consistent pattern dominated by unconsolidated sand and gravel layers, often interbedded with clay or occasional cobbles/boulders. Wells are generally completed entirely within these glacial/fluvial deposits. Static water levels are shallow to moderate, typically 16–45 ft below grade. The most common sequence is: a surface soil and/or upper sand & gravel unit; local clay/gravel/silt or hardpan interbeds, especially at intermediate depths; then a basal sand (sometimes with gravel) which is commonly the primary aquifer. Wells for reliable residential yield (5–15+ GPM) are typically completed at 80–110 ft. Higher capacity wells or those supplying larger demands may be screened slightly deeper or within thicker sand/gravel units extending to 150–200+ ft where present.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 2 ft | Topsoil | Thin organic or loamy soil horizon; may include silt and cobbles. | Color: Brown Hardness: Loose |
2 – 50 ft | Sand and Gravel | Clean to dirty sand and gravel, local zones with cobbles, moderate caving; excellent water bearing. | Color: Varies: yellow-brown/dark brown Hardness: Loose to medium |
50 – 80 ft | Clay with Gravel/Silty Sand | Interbedded sandy clay, sandy red clay, or clayey gravel; some localized hardpan or compacted layers. May act as minor aquitard. | Color: Red/brown/gray Hardness: Firm to hard |
80 – 110 ft | Coarse Sand and Gravel | Coarse water-bearing sand & gravel, commonly caving, sometimes with occasional cobbles. Major aquifer unit. | Color: Light brown/yellow/gray Hardness: Loose |
110 – 180 ft | Sandy Clay/Clay with Sand (deeper wells only) | Layer not always present; found in deeper or outlying wells. Dense sandy to firm clay, intermixed with sand. | Color: Brown/gray Hardness: Firm to hard |
180 – 206 ft | Sand (Deep Basal Unit) | Clean to slightly gravelly sand, major water-producing zone in deepest wells. | Color: Gray/yellow Hardness: Loose |
