Hammond, WI54015
A typical Hammond-area well penetrates layers of topsoil, clay (sometimes with sand or gravel), sand/gravel, and thick limestone/dolomite bedrock. Residential wells (5-15+ GPM) are usually 100-130 ft deep; high-capacity or deep wells may reach 150-180+ ft.

Recommended Method
The most representative geological profile for Hammond and surrounding areas, based on a synthesis of local well logs, consists of an uppermost layer of topsoil and/or clay, occasionally interbedded with sand or gravel. This is followed by a zone of clean sand and gravel (or sand/gravel with clay), which transitions to a competent limestone/dolomite bedrock that typically serves as the primary aquifer. The clay/sand/gravel zone thickness varies but is frequently between 15-60 ft before entering the limestone/dolomite aquifer. The static water table is typically found between 30 and 100 ft below grade, with wells completed in limestone commonly yielding 10-15+ GPM. Standard residential wells are 100-130 ft; deeper or high-yield wells extend to 160-180 ft or more.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 2 ft | Topsoil | Surface soil layer, often dark, organic-rich; may not always be separately noted if thin. | Color: Brown or Black Hardness: Soft |
2 – 15 ft | Clay (with sand and/or gravel possible) | Brown/tan clay, frequently intermixed with sand or gravel; layer may be subdivided in some logs. | Color: Brown, Tan, or Gray Hardness: Soft to firm |
15 – 55 ft | Sand & Gravel | Clean to slightly silty or gravelly sand or sand and gravel mix; significant water-bearing zone above and/or within limestone. | Color: Yellow, Tan, Light Brown Hardness: Loose to firm |
55 – 120 ft | Limestone/Dolomite (may include thin broken/transition zone at top) | Limestone (and/or dolomite), typically hard, pale yellow to gray; uppermost 5-10 ft may be broken or transition rock. | Color: Light yellow, gray, tan Hardness: Hard |
120 – 180 ft | Limestone/Dolomite | Massive limestone/dolomite, principal aquifer; persists as deepest encountered formation in sampled wells. | Color: Light yellow, gray, tan Hardness: Hard |
