A geological estimate for the Randolph area.
Typical Well Depth
Static Water Level
Recommended Method
Based on reviewed well logs in the Randolph area and nearby communities, the typical subsurface profile starts with thin clay (often with gravel/silty materials), followed by a significant massive limestone/dolomite layer, and then a thick, water-bearing sandstone formation that serves as the main aquifer. Occasional shale interbeds may be noted in the transition from limestone to sandstone. The most common drill method is rotary with mud circulation. Residential wells typically reach depths of 120–140 feet to access sufficient, reliable yields. High-capacity wells often extend deeper to optimize yields from the sandstone aquifer.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 5 ft | Clay | Stiff to silty clay, occasionally black dirt or with minor gravel | Color: Brown/Black Hardness: Firm |
5 – 15 ft | Silty Clay/Gravel | Silty clay with gravel, stones, occasional boulders; local valleys may have thicker deposits | Color: Mixed Hardness: Medium |
15 – 80 ft | Limestone/Dolomite | Limestone or dolomite, occasionally with thin interbedded shale layers | Color: Gray/Buff Hardness: Hard |
80 – 130 ft | Sandstone | Fine to medium sandstone, commonly the main water-bearing aquifer, sometimes mixed with thin shale or limey layers | Color: Light Brown/Tan Hardness: Soft to Medium |
130 – 175 ft | Sandstone (deeper) | Extended sandstone zone, may include more shale or remain thick-bedded, often tapped for high-yield wells | Color: Buff/Tan Hardness: Medium |
