Typical Well Depth
Static Water Level
Recommended Method
The representative Sterling well profile begins with a surficial sand or sand & gravel layer (3–12 ft), underlain by thick sequences of clay (often in multiple beds) generally extending to 80–140 ft. Interbedded sand or sand/gravel layers are commonly found at various depths within these clays. Most wells reach into consolidated bedrock formations—typically shale, sandstone, or a sequence of both—beginning about 90–165 ft deep and extending as deep as 200+ ft in some cases. The most prolific water-bearing zones are often sand/gravel seams or the upper portions of sandstone or fractured consolidated rock. Shale is present and may be hard or soft; sandstone intervals can also be significant. Expected static water levels are commonly 10–40 ft below grade, with 5–15+ gpm possible at 80–180 ft depths for residential use. High-capacity wells may require deeper construction, often to the top of sandstone, typically 160–200+ ft.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 8 ft | Sand | Surficial sand layer, occasional mixed sand & gravel | Hardness: Loose |
8 – 38 ft | Clay | Thick clay, sometimes blue or red; commonly subdivided into stiffer and softer beds | Color: Red/Blue/Grey Hardness: Soft to firm |
38 – 78 ft | Clay with occasional Sand Lenses | Mixed beds of clay with occasional lenses of sand or sandy clay; possible thin gravel seams | Hardness: Variable |
78 – 130 ft | Clay and Shale | Clay gradually transitions to soft then hard shale; some sites report blue or black shale | Color: Dark grey/black/blue Hardness: Soft to hard |
130 – 165 ft | Shale, Sandstone, and/or Gravel | Alternating layers of hard shale, sandstone, with occasional gravel seam at base; quality and thickness vary locally | Hardness: Hard |
165 – 200 ft | Sandstone and Shale | Massive sandstone with interbedded shale; may include limestone at base in some isolated locations | Hardness: Consolidated rock |
200 – 235 ft | Hard Bedrock (Shale/Sandstone/Limestone) | Base of typical well profile; some wells penetrate additional thin limestone or persistent shale | Hardness: Very hard |
