In the Leslie, MI region, water wells most commonly encounter a near-surface sequence of variable clay, gravel, and sand ranging from 20 to 50 feet thick, followed by alternating layers of clay, shale, and consolidated sandstone. The most persistent pattern is: (1) brown to gray clay and/or sand/gravel in the upper ~20–55 feet, (2) a thick sequence of shale occasionally interbedded with sandstone or limestone between ~60–140 feet, and (3) a basal sandstone from approximately 130–190+ feet. Static water levels are consistently found between 15–40 feet below grade. Typical residential wells providing 5–15+ GPM are commonly drilled to 130–190 ft (occasionally deeper for higher yields), with casing set through unconsolidated and upper bedrock zones, and grouted to the base of casing depth.
| Depth (Feet) | Formation Type | Description | Characteristics |
|---|---|---|---|
| 0 – 15 ft | Brown/Gray Clay | Fine-grained, with minor silt or sand lenses; plastic; generally moist. | Color: Brown/Gray Hardness: Soft |
| 15 – 55 ft | Sand and Gravel with Clay | Gravelly sand with some clay, occasional stones; grading downward to more clay-rich horizons. | Color: Brown/Gray Hardness: Medium, loose to compact |
| 55 – 100 ft | Shale (with Limestone/Sandstone interbeds) | Predominantly gray or green shale, may include thin limestone or sandstone streaks; locally fissile. | Color: Gray/Green Hardness: Firm |
| 100 – 140 ft | Shale and Sandstone Transition | Interbedded gray/green shale with more persistent sandstone units; more consolidated downwards. | Color: Gray/Green/Light Brown Hardness: Firm to moderately hard |
| 140 – 190 ft | Sandstone (sometimes White/Green with minor shale interbeds) | Moderately hard, water-bearing sandstone with good porosity; may appear white or greenish, with occasional shale lenses. | Color: White/Gray/Green Hardness: Hard |
| 190 – 240 ft | Sandstone (Deep/Optional, high capacity only) | Massive hard sandstone, locally with increased water yields at base of sequence. | Color: White/Gray Hardness: Hard |
