Putnam Well Drilling
Perry, MI48872
A typical Perry-area well encounters a thick sequence of glacial till, sand/gravel, and multiple interbedded clay layers overlying deep shale and sandstone bedrock. Residential wells most commonly finish in the shallowest water-bearing sand/gravel or in bedrock sandstone.

Recommended Method
Based on synthesized data from several nearby wells, the most representative profile for Perry and its region begins with brown/yellow clay and occasional gravel to ~15-25 ft, followed by interbedded fine to coarse sand and gravel with mixed clays extending to approximately 85-110 ft. Beneath is a variable sequence of clay with stones, silty or gravely clays (often reaching around 150-180 ft). The most consistent bedrock contact appears as black and gray shale starting near 100-175 ft, often quickly interbedded with gray/white sandstone that may become fully dominant at greater depths. The consolidated sandstone and shale beds continue to the bottom of most logs, with water yields generally best in the lower sandy/sandstone units. Static water levels are typically 20-45 ft below grade, depending on surficial geology and proximity to recharge. Residential wells with 5–15+ GPM capacity commonly finish at 100-160 ft, generally at or just below the first persistent coarse sand/gravel or shallow bedrock sandstone.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 15 ft | Clay (Brown/Yellow) | Soft, occasionally contains gravel; typical of glacial till. | Color: Brown-Yellow Hardness: Soft-Plastic |
15 – 55 ft | Sand & Gravel (Fine-Coarse, with Some Clay) | Interbeds of fine to coarse sand, occasional gravel, mixed with lenses of clay. Main surficial aquifer where present. | Color: Gray-Tan Hardness: Medium |
55 – 95 ft | Clay with Stones / Gravelly Clay | Gray or reddish clay, often with gravel or stones. Locally silty or sandy. | Color: Gray-Red Hardness: Firm |
95 – 110 ft | Sand & Gravel (Water-Bearing) | Mostly clean, medium-coarse sand/gravel, possible thin clay partings. Main shallow aquifer unit. | Color: Light Gray Hardness: Medium |
110 – 175 ft | Shale (Black & Gray, Locally with Clay) | Consolidated shale; color varies from black to gray. May include thin sandstone or clay beds. | Color: Gray-Black Hardness: Hard |
175 – 220 ft | Sandstone & Shale (Alternating, with White Sandstone Prominent) | Alternating layers; lower section increasingly dominated by fine-grained white sandstone, major aquifer for deep wells. | Color: White-Gray Hardness: Hard |
220 – 305 ft | Consolidated Sandstone/Shale (Bedrock) | Regionally extensive aquifer - white or gray sandstone, parting shale. Continues to maximum logged well depths. | Color: White-Gray Hardness: Very Hard |
