A&B Well Drilling
Kimball, MI48074
The typical Kimball region well intersects surficial sand or clay, followed by thick sequences of blue/gray clay (often gravely or sandy), and terminates in a thin basal gravel, sand, or bedrock sandstone aquifer.

Recommended Method
Most wells in the Kimball area begin with a thin sand or sandy clay layer (1–10 ft) at the surface, overlain by thick blue/gray/grayish clay, sometimes with interbeds of sand or gravel. Water-bearing zones are typically thin zones of sand, gravel, or occasionally sandstone at depth. Clay is dominant throughout, with water production generally coming from the lowermost unit, just above or in contact with any bedrock encountered. Surficial sand and topsoil are present but not major aquifers. The main producing aquifer, supporting 5–15+ GPM, is generally encountered between 60–135 ft, though deeper bedrock sources exist at 185–191 ft.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 2 ft | Topsoil/Sand | Black or yellow topsoil or sand, sometimes mixed with clay at surface. | Color: Black/Yellow/Brown Hardness: Soft |
2 – 10 ft | Sand/Sandy Clay | Yellow or sandy surface horizon grading to clay; may contain minor sand seams. | Color: Yellow/Gray Hardness: Soft-Moderate |
10 – 105 ft | Clay (Gray/Blue, Sandy/Gravely/Soft-Hard) | Very thick sequence of blue or gray clay, often partly sandy, gravely, or alternating soft and hard clay. Occasionally interrupted by thin sands or silty seams (1–3 ft thick). | Color: Gray, Blue, Brown (locally) Hardness: Soft-Hard layers |
105 – 130 ft | Clay (Gravely/Hard, with sand/gravel interbeds) | Transition to harder or gravely gray clay, frequently with increasing gravel/sand near the base. May have thin fine sand lenses (~1–5 ft) acting as minor aquifers. | Color: Gray Hardness: Hard |
130 – 137 ft | Gravel/Sand (Aquifer) | Coarse sand/gravel zone, commonly yielding water for domestic wells. Sometimes replaced by sandstone or a sand/gravel/bedrock contact at greater depths. High permeability, most well screens placed here. | Color: Gray/Varied Hardness: Loose/Unconsolidated |
137 – 191 ft | Clay (occasionally with Bedrock/Sandstone at base) | Gravely or hard clay persists with occasional bedrock (typically sandstone) forming the deepest aquifers in rare, deep wells. | Color: Gray/Blue Hardness: Hard (or consolidated if bedrock) |
191 – 191 ft | Sandstone (Bedrock; rare) | Rarely encountered, forms the aquifer base in deepest wells. | Color: Gray/Light Brown Hardness: Very Hard |
