Recommended Method
Based on compiled logs from multiple sampled wells around Waupun, the most typical subsurface profile begins with a surficial layer of glacial material (mainly clay, frequently mixed with gravel and sometimes minor sand or boulders), transitioning sharply to a thick sequence of limestone or dolomite bedrock. Some wells encounter thin shale interbeds within the carbonate interval. At deeper locations, the carbonate bedrock gives way to sandstone, which can form a significant lower aquifer. Well construction is rotary with mud circulation, using steel casing generally set to the base of unconsolidated material. Typical residential wells are completed in the upper carbonate aquifer, with deeper completions necessary for higher yields or high-capacity needs.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 5 ft | Clay (occasionally with Gravel/Silt/Loam) | Brown to gray, plastic, caving, glacial till and occasional surficial fill. | Color: Brown/Grey Hardness: Soft |
5 – 35 ft | Clay & Gravel (Glacial, may contain boulders/sand as local variant) | Mixed glacial outwash. May contain some loam, boulders, or silt. Water bearing may occur at base. | Color: Mixed Brown/Grey Hardness: Soft to Medium |
35 – 90 ft | Limestone/Dolomite | Sedimentary bedrock, locally fractured, dense, in places slightly shaly. | Color: Gray/Buff Hardness: Hard |
90 – 150 ft | Limestone/Dolomite (minor Shale beds possible) | Dense carbonate, some shale interlaminations, commonly water bearing. | Color: Light Gray Hardness: Hard |
150 – 185 ft | Limestone/Dolomite (occasional Shale) | Similar to above, transitions to increasing sand content lower down. | Color: Gray Hardness: Hard |
185 – 265 ft | Sandstone | Fine to medium grained quartzose sandstone; water bearing. | Color: Light Tan/Yellow Hardness: Medium |
