Sandusky, MI48471
The typical Sandusky-area well penetrates clay (variously colored), some gravel/silty sand, then Marshall/bedrock sandstones alternating with shale layers, with primary aquifers in sandstone formations below ~40–60 ft.

A representative household well in the Sandusky, Michigan region typically begins with a surface interval of mixed clay (yellow, brown, gray, blue, or red), usually extending from the surface to approximately 35–45 feet. This is often underlain by a minor gravel and/or silty sand zone, sometimes water-bearing. Below these unconsolidated sediments, bedrock is encountered as alternating intervals of predominantly gray, white, or brown Marshall Sandstone and shale (gray, dark gray, or soft/hard). The most productive aquifer zones are consistently found within the sandstone layers between about 40 and 100 feet. Shale layers are often present within or beneath the main sandstone zones. The static water level across the sampled area averages around 15–20 feet. Residential wells (5–15+ GPM) are typically completed between 80 and 100 feet, with high-capacity/supply wells completed to depths of 120–125 feet.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 8 ft | Clay | Surface clay layer, commonly yellow, brown, red, or gray with some stone inclusions. | Color: Yellow/Brown/Red/Gray Hardness: Soft to firm |
8 – 42 ft | Clay (with occasional sand/gravel beds) | Dense blue or gray clay, occasionally interbedded with thin silty sand/gravel lenses, locally stoney. | Color: Gray/Blue Hardness: Firm to hard |
42 – 50 ft | Sand/Gravel (occasionally water bearing) | Sandy gravel or silty sand, sometimes with stones, typically water bearing. | Color: Gray/Brown Hardness: Medium |
50 – 64 ft | Sandstone (Marshall; may include thin shale partings) | Gray, white, brown, or dark gray sandstone, sometimes hard, sometimes soft, prime water-bearing interval. Minor thin shale partings possible. | Color: Gray/White/Brown/Dark Gray Hardness: Soft to Hard |
64 – 80 ft | Shale (with thin sandstone interbeds possible) | Gray or dark gray shale with mixed hardness, typically forms less productive, soft, or layered intervals. | Color: Gray/Dark Gray Hardness: Soft to Hard |
80 – 120 ft | Sandstone (Marshall or equivalent) | Massive gray/white/brown/dark gray sandstone, highly productive and commonly used as the main aquifer for both residential and high-capacity wells. | Color: Gray/White/Brown/Dark Gray Hardness: Medium to Hard |
