A representative geological profile in the Rockford, MI region (including Grand Rapids and nearby townships) begins with a surficial clay or mixed glacial till, commonly 7-15 ft thick. This is most often underlain by alternating sequences of clay (red, brown, blue) and sand; gravel and sand/gravel mixes frequently appear beneath or within these units to depths of 60-85 ft. Several wells report a persistent thick sand/gravel aquifer (commonly between 27-70 ft thick). Deeper wells (rare in this sample) may transition into extensive clay, then gravel and bedrock (limestone/sandstone). The most common aquifer source for residential wells is sand or sand/gravel layers between 30 and 90 ft depth, producing 10-30+ GPM. Bedrock or deeper sandstones appear only in the deepest wells (rarely needed for residential supply). Typical static water levels range from 29 to 86 ft, with most around 30-41 ft. Residential wells (5–15+ GPM) are generally screened in sand/gravel at 65–90 ft, with average casing to 70–85 ft.
| Depth (Feet) | Formation Type | Description | Characteristics |
|---|---|---|---|
| 0 – 12 ft | Clay | Glacial till, mottled (occasionally red, brown, blue) | Color: Variable (brown, red, blue) Hardness: Soft to medium |
| 12 – 30 ft | Clay with sand and gravel interbeds | Mixed lenses, becoming sandier with depth | Color: Brown to gray Hardness: Medium |
| 30 – 65 ft | Sand (occasional gravel) | Clean to silty sand, minor gravel beds; major aquifer in most wells | Color: Light brown/gray Hardness: Loose to medium |
| 65 – 85 ft | Clay, brown/blue | Dense clay, occasional sand stringers | Color: Blue/gray/brown Hardness: Hard |
| 85 – 90 ft | Sand/gravel (water-bearing) | Aquifer zone; most screens set here for deeper household wells | Color: Light brown/gray Hardness: Loose |
| 90 – 130 ft | Clay with occasional sand/gravel beds (deep wells only) | Clay dominant, possibly with deeper sand/gravel for high-capacity wells | Color: Gray/brown Hardness: Very hard |
| 130 – 244 ft | Bedrock (limestone & sandstone) | Solid bedrock; only encountered in deepest wells. Not typical for residential. | Color: Gray/light brown Hardness: Very hard |
