Indian River, MI49749-9792
The typical Indian River well penetrates alternating layers of sand/gravel, clay/hardpan, and mixed units, with the most common sequence being surface sands/gravel, followed by thick clay/hardpan, then water-bearing sands or sand/gravel at depth.

A synthesized geological profile for the Indian River region reveals an upper portion dominated by sand and/or sand & gravel layers, often underlain by thick clay, sandy clay, or hardpan. Additional alternating layers of sand, gravel, hardpan, and clay are common, with deeper water-bearing sands or sand/gravel layers typically targeted for well screens—often below 40-50 ft, but sometimes much deeper. Hardpan units frequently separate major sand/gravel aquifers. Residential wells are commonly completed between 50-120 ft, with higher capacity wells requiring depths of 120-230+ ft depending on production needs.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 8 ft | Sand/Sand & Gravel | Surface layer of sand, sometimes mixed with gravel; generally loose and water-bearing. | Color: Buff/Tan Hardness: Soft |
8 – 40 ft | Clay/Hardpan | Dense clay, sandy clay, or hardpan—may contain occasional embedded gravel seams or thin sand interlayers. | Color: Gray/Blue/Brown Hardness: Hard/Compact |
40 – 60 ft | Sand & Gravel | Water-bearing sand and gravel zone, key aquifer horizon for most residential wells. | Color: Buff/Gray Hardness: Medium |
60 – 105 ft | Clay/Hardpan (with mixed sand) | Alternating clay and hardpan, sometimes layered with thin beds of sand/gravel. May be interbedded with sandy/gravelly patches. | Color: Gray/Dark Hardness: Hard |
105 – 120 ft | Sand Fine to Medium | Fine-to-medium sand, represents deeper aquifer; sometimes blended with gravel. Targeted by deeper or high capacity wells. | Color: Buff/Light Gray Hardness: Soft to Medium |
120 – 180 ft | Clay/Hardpan (Deep) | Thick hard clay or hardpan, may contain some mixed sand/gravel or silt lenses. | Color: Gray/Brown Hardness: Hard |
180 – 230 ft | Sand & Gravel/Water-Bearing Zone | Deep productive sand and gravel, key for high-capacity or flowing wells. | Color: Buff/Gray Hardness: Medium |
