A review of well logs from the Cassopolis area reveals a consistent geological profile: thin surficial topsoil, underlain by interleaved sand/sand & gravel and clay layers. The most common sequence begins with 1-3 ft topsoil, followed by sand or sand & gravel (20-40 ft), a substantial clay or clay-mixed layer (10-25 ft), then another thick sand or sand & gravel unit (20-40 ft). Deeper layers (<120 ft) tend to be fine to medium sands or additional clay with some gravel. Static water levels are generally encountered between 10-44 ft below ground. Wells yielding 5-15+ GPM commonly draw from sand & gravel aquifers between 60-120 ft depth. The rotary mud circulation method is most frequently used.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 2 ft | Topsoil | Thin layer of organic topsoil, sometimes sandy. | Color: Brown Hardness: Soft |
2 – 15 ft | Sand, Sand & Gravel (occasional stones/clay) | Variable mixture, mostly medium/coarse sand with gravel; occasional stones or clay streaks. | Color: Brown, Red, Gray Hardness: Medium |
15 – 35 ft | Clay (minor sand and/or gravel) | Predominantly clay, often brown or gray; may include bands of sand or gravel—often significantly reduces permeability. | Color: Brown, Gray Hardness: Hard |
35 – 65 ft | Sand & Gravel | Thick, productive aquifer zone—medium to coarse sand and gravel mix. | Color: Brown, Gray Hardness: Loose to medium |
65 – 80 ft | Clay or Clay with Sand/Gravel | Intermediate clay layer, can include gravel or sand streaks. | Color: Gray, Brown Hardness: Hard |
80 – 120 ft | Sand (medium to coarse) and/or Sand & Gravel | Major water-bearing zone; predominantly sand with abundant gravel, grading finer with depth. | Color: Brown, Gray Hardness: Loose to medium |
