Oxford, MI48371
The typical Oxford, MI geological profile (to ~135 ft) consists of interbedded clay, sand, and gravel layers with a persistent water-bearing gravel/sand & gravel zone beginning around 70-80 ft and extending to total well depth. Residential wells commonly are 75-135 ft deep and designed for 10-30 GPM yield.

Recommended Method
Averaging across representative wells from Oxford and adjacent townships, the predominant sequence is initial layers of clay (some with sand or gravel) in the upper 15-30 feet, followed by alternating units of sand & gravel, clay with gravel, and sand & clay mixtures. The most consistent water-bearing zone is a gravel or sand & gravel interval beginning near 70-80 ft, commonly persisting to the bottom of the well (typically 125-135 ft in Oxford). Occasional thicker clay (to 100+ ft) occurs but is less typical. Residential wells are usually completed between 75-135 ft with static water levels of 20-95 ft below grade and yields of 10-30 GPM.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 15 ft | Clay (locally with sand or gravel) | Brown to gray clay, locally sandy or gravelly; acts as confining or semi-confining layer. | Color: Brown/Gray Hardness: Soft |
15 – 45 ft | Sand & Gravel / Gravel | Poorly sorted sand and gravel, occasional clay inclusions; transition to more permeable zones. Water-bearing potential begins. | Color: Gray to brown Hardness: Medium |
45 – 70 ft | Clay & Gravel | Interlayered clay, gravel, and occasional sand; can be locally compact. | Color: Gray Hardness: Medium |
70 – 120 ft | Sand & Gravel (Water-bearing) | Dominant aquifer unit; high yield zone of mixed sand and gravel with minor clay. Primary production interval for most residential wells. | Color: Gray to brown Hardness: Loose to medium |
120 – 135 ft | Gravel / Fine Sand & Gravel | Clean, coarse gravel and/or fine sand and gravel; uppermost part of deeper aquifer, highest specific yield. | Color: Gray Hardness: Loose |
