The representative geological cross-section for private wells in the Racine area typically features a sequence beginning with clay (varying from red, yellow, to blue) at the surface, transitioning into units of gravel and sand. These glacial deposits are generally followed by hardpan or further clay interbeds, then a thick section of limestone or dolomite bedrock. Average total well depths for residential supply wells (capable of 5-15 GPM or more) are around 125-160 ft, while higher capacity/deeper wells extend to approximately 220-270 ft, especially where full penetration of the bedrock aquifer is required. Static water levels commonly range 40-80 ft but may vary based on local hydrogeology.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 15 ft | Clay | Topsoil or yellow/reddish clay with some sandy zones | Color: Yellow/Red Hardness: Soft |
15 – 40 ft | Clay | Blue/brown clay; often compact and may contain occasional stones | Color: Blue Hardness: Medium |
40 – 130 ft | Clay with Gravel and/or Sand Lenses | Interbedded layers of blue clay, sand, and gravel; part of glacial drift sequence | Color: Blue/Grey Hardness: Mixed |
130 – 145 ft | Sand & Gravel | Gravel and sand aquifer zone; transition to bedrock | Color: Grey/Yellow Hardness: Loose to Medium |
145 – 240 ft | Limestone/Dolomite (Silurian bedrock) | Hard, fractured dolomite and/or limestone bedrock, principal water-yielding zone | Color: White/Tan Hardness: Hard |
