Static Water Level
Recommended Method
The representative geological profile for Springport, averaged from several regional well logs, typically includes: an upper sand, sandy clay, or clay layer (usually brown/gray), underlain by alternating clay and gravel or sand/gravel packages, transitioning to bedrock composed of sandstone, shale, or both. The sequence may vary slightly in thickness per location, but the overall stack is consistent. Most residential wells are completed before or within the top of the sandstone or near the thickest sand/gravel zones, with static water levels generally between 15–36 ft below surface and typical yields exceeding 10 GPM. A standard residential well is usually drilled to 90–130 feet, while higher capacity or bedrock completions may extend to 180+ feet. PVC casing is most common, typically grouted with bentonite slurry to the bottom of the casing.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 8 ft | Sand / Sandy Clay / Brown Clay | Brown to gray sand, sandy clay, or clay—loosely consolidated, occasional gravel. | Color: Brown/Gray Hardness: Soft |
8 – 25 ft | Clay (Occasional Gravel) | Gray or brown clay, locally with gravel seams or mixed fine sand. | Color: Gray/Brown Hardness: Soft to firm |
25 – 45 ft | Sand & Gravel / Gravelly Clay | Sand and gravel intervals, some zones with gray gravelly clay or interbedded clay. | Color: Mixed/light brown/gray Hardness: Moderate |
45 – 68 ft | Clay / Hard Clay | Thicker package of hard or firm clay, often gray or brown; may include fine gravel. | Color: Gray/Brown Hardness: Firm to hard |
68 – 85 ft | Sandstone and/or Sand & Gravel | Transition to sandstone or thick sand & gravel at or just below the major clay; can include some shale or stony layers. | Color: Light brown/yellow/gray Hardness: Hard (sandstone), loose (sand/gravel) |
85 – 120 ft | Sandstone (occasional shale, clay interbeds) | Dominantly sandstone, often brown or gray; short shale, clay, or broken stone stringers. | Color: Brown/Gray Hardness: Hard |
120 – 180 ft | Shale/Sandstone (Bedrock) | Shale and sandstone layers; often darker, competent bedrock. Most deeper/higher capacity wells are finished in this interval. | Color: Gray/Brown/Dark Hardness: Hard |
