The typical geological profile for residential wells in the Homer, MI region consists of alternating unconsolidated sands, gravels, and clays, followed in many cases by sandstone (often water-bearing) and occasional shale, with typical residential well depths ranging from 65 to 130 feet and high-capacity/bedrock wells averaging around 180 feet.

Recommended Method
Based on the synthesis of several well logs from the Homer (Calhoun County) vicinity, the most representative geology consists of a surficial layer of sandy/gravelly clay, transitioning into alternating lenses of sands, gravels, and clays to approximately 90–110 feet. Many wells then reach consolidated formations dominated by sandstone, sometimes interbedded with shale, frequently water-bearing. Drilled depths for residential water supply (5–15+ GPM) typically end in coarse sand/gravel or enter the upper portion of bedrock (sandstone). Static water levels are commonly 13–39 feet below grade. Casing is primarily PVC to the bottom of the unconsolidated zone or just into bedrock. Rotary mud circulation is the standard drilling method, and annular space is grouted to casing depth (typically with bentonite slurry).
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 15 ft | Sand & Gravel w/Clay | Brown clayey sand and gravel, sometimes sandy clay or gravelly clay | Color: Brown Hardness: Soft |
15 – 35 ft | Sand / Sandy Clay | Brown sand or sandy clay, may include some fine gravel or silt | Color: Brown/Gray Hardness: Soft |
35 – 55 ft | Clay / Clay with Gravel | Gray to brown clay, some with fine gravel lenses, may be locally stiffer | Color: Gray/Brown Hardness: Mostly soft |
55 – 90 ft | Sand & Gravel (water-bearing) | Medium to coarse sand and gravel, sometimes with thin clay partings | Color: Gray/Brown Hardness: Soft to loose |
90 – 130 ft | Clay & Gravel / Sand | Alternating sandy clay, gravelly clay, and sand layers; decreasing fines with depth | Color: Gray/Brown Hardness: Soft to firm |
130 – 160 ft | Sandstone (locally water-bearing) | Light to red sandstone, commonly fractured, may include shale bands or broken zones | Color: Light Gray/Red Hardness: Hard |
160 – 180 ft | Sandstone with Shale | Sandstone becoming more massive with interbedded shale; water produced from fractured zones | Color: Gray/Red Hardness: Hard |
