Recommended Method
The most representative geological profile in the Howard City area, as seen from multiple well logs, starts at the surface with a layer of clay (frequently brown, red, or gray), followed by alternating layers of sand and clay. Water-bearing sand or sand mixed with gravel is a consistent aquifer unit, usually found below the primary confining clay layer, commonly between 35 and 110 feet. Clay layers tend to show color variations, and the usable aquifer is most frequently a medium to coarse sand or sand and gravel. The average static water level is around 16 to 22 feet below grade. Most residential wells producing 10–15+ GPM are completed between 45 and 80 feet, while higher capacity wells may target thicker sand/gravel units extending to 100–110 feet.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 3 ft | Topsoil/Clay | Brown, red, or gray clay or soil at surface, sometimes with topsoil. | Color: Brown/Red/Gray Hardness: Soft |
3 – 15 ft | Clay (with some sand inclusions in places) | Primarily clay; often transitions from brown to gray; may include thin sand seams. | Color: Brown to Gray Hardness: Soft to Medium |
15 – 35 ft | Sand (occasionally thin clay layers) | Fine to medium sand, minor clay partings in some wells. | Color: Brown Hardness: Loose |
35 – 45 ft | Clay or Clay with Gravel | Gray or mixed clay with some gravel; moderate confining material. | Color: Gray Hardness: Medium |
45 – 75 ft | Sand or Sand & Gravel (water-bearing) | Main aquifer zone – coarse to medium sand, often with significant gravel content. | Color: Brown Hardness: Loose |
75 – 99 ft | Sand with Clay partings | Deeper sand, with some layers of brown or gray clay; locally more gravelly. | Color: Brown/Gray Hardness: Moderate |
99 – 110 ft | Sand & Gravel (deep aquifer extension) | Thick, coarse sand/gravel, excellent water producer where present. | Color: Brown Hardness: Loose |
