Typical Well Depth
Static Water Level
Recommended Method
Based on synthesis of well logs from across the Kalamazoo region, the most representative well begins with topsoil or fill, followed by alternating clay (often blue/gray or brown) and sandy or gravelly layers. Coarse sand and sand & gravel units commonly form the main aquifers, typically occurring below significant thicknesses of fine sand or clay. The static water level is usually found well above the primary producing zone. Typical residential wells are cased to near the aquifer and screened in coarse, water-bearing sand or sand/gravel. High-capacity wells would extend to the lower sand & gravel aquifers.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 5 ft | Topsoil or Fill | Topsoil, possibly with gravel or sand fill in disturbed areas | Color: Brown/variable Hardness: Soft |
5 – 25 ft | Sand & Gravel / Clay | Interbedded sand, fine gravel, and brown/gray or blue clay | Color: Brown to gray or blue Hardness: Soft to firm |
25 – 70 ft | Clay (often blue/gray), some fine sand | Thick sequence of blue/gray/brown clay, with localized beds of sand or fine gravel | Color: Blue, gray, brown Hardness: Medium to hard |
70 – 100 ft | Sand & Gravel (water bearing) | Coarse sand with gravel, primary household-aquifer; may alternate with thin clay streaks | Color: Yellow, gray, tan Hardness: Medium |
100 – 145 ft | Clay, Clay with Sand & Gravel | Dense clay, may contain some sand and gravel layers | Color: Gray, blue, brown Hardness: Hard |
145 – 170 ft | Sand & Gravel (coarser, water bearing) | Thicker, coarser sand and gravel, serves as a major aquifer for deeper residential and high-capacity wells | Color: Yellow, tan, mixed Hardness: Medium |
170 – 185 ft | Sand and Gravel (saturated, possible lower aquifer) | Very coarse, clean sand and gravel, thick saturated zone in deepest wells | Color: Gray, tan Hardness: Medium |
