Typical Well Depth
Static Water Level
Recommended Method
Wells in the Gillett region commonly encounter a surficial sand or sand/gravel layer, followed by a sequence of clay or sandy clay. This is typically underlain by a coarser sand or gravel unit, and most wells finish in water-bearing sandstone, which provides reliable yields. The static water level commonly ranges from 5-25 ft below ground. Residential wells yielding 5-15+ GPM are typically drilled to 60-100 ft, while higher capacity wells or those targeting more robust sandstone aquifers may go deeper (up to 180 ft or more).
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 12 ft | Sand, with possible gravel or stones | Light to medium sand, sometimes with gravel or stones, loose | Color: Light/varied Hardness: Loose |
12 – 38 ft | Sandy clay or clay | Very fine sand mixed with clay or silty clay, cohesive | Hardness: Firm |
38 – 52 ft | Sand or gravel, sometimes water-bearing | Coarse sand and/or gravel, may be water-bearing; transition zone | Hardness: Medium |
52 – 90 ft | Sandstone (occasionally some hard sandstone/limestone) | Water-bearing sandstone, typically medium to hard; sometimes interbedded with hardpan or thin limestone | Color: White/yellowish Hardness: Hard |
90 – 120 ft | Sandstone (deeper aquifer) | Thick, continuous water-bearing sandstone (where drilled deeper) | Color: White/yellow Hardness: Hard |
