Recommended Method
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 |
