Detailed Summary
Representative residential and municipal wells in the Onekama region most frequently encounter a surface layer of fine to medium sand with local gravel, followed by alternating sequences of sand, sand with clay, and layers of silty or gray/brown clay. Deeper stratigraphy generally transitions into thick, contiguous clay, capped by water-bearing sands or sand-gravel units at greater depths (>80 ft). Very deep wells (>250 ft) may encounter massive sand aquifers below thick clay. Static water levels are typically shallow (10-20 ft below grade) in most household wells, though can be significantly deeper in select locations (e.g., >100 ft). Wells achieving 5–15+ GPM are commonly completed at 50–110 ft, screened in the basal sand/gravel aquifers encountered below the principal clay sequence. High capacity municipal wells may require drilling 200–500+ ft, depending on local variations and increased clay thickness.
Expected Geological Layers
| Depth (Feet) | Formation Type | Description | Characteristics |
|---|---|---|---|
| 0 – 18 ft | Sand & Gravel | Fine to medium sand, with intervals of gravel or mixed sand & gravel; locally brown or tan. | Color: Brown/Tan Hardness: Loose to medium |
| 18 – 45 ft | Sand and Clay | Interbedded sand and clay; commonly moist to wet; transitions between sandy and more clayey zones. | Color: Brown/Gray Hardness: Medium |
| 45 – 80 ft | Clay (with sandy seams) | Dense, silty or sandy clay, occasionally with thin laminae of sand; persistent throughout region. | Color: Gray/Brown/Tan Hardness: Hard to very hard |
| 80 – 110 ft | Sand (fine to medium, water-bearing) | Clean, fine to medium sand, sometimes with gravel; main residential aquifer; screened and water bearing. | Color: Tan/Gray Hardness: Loose to medium |
| 110 – 250 ft | Clay (interbedded with sand/silt and deeper sand) | Thick, hard clay with some silt/sandy laminae; deeper sands (below 200 ft) may be present in deeper/municipal wells. | Color: Gray/Brown Hardness: Hard |
| 250 – 510 ft | Sand (deep aquifer, high capacity wells only) | Massive sand, sometimes with gravel; major aquifer in municipal/irrigation wells; locally up to 310 ft thick. | Color: Tan/Gray Hardness: Loose to medium |
