Afton's typical geological profile consists of a thin surficial soil/gravel cover, underlain by alternating sequences of alluvial silt, sand and clay, becoming increasingly gravelly and sandy with depth, before encountering fractured bedrock (primarily limestone or basalt). Residential wells most often reach water in coarser, unconsolidated sand and gravel zones above or at the upper part of the bedrock contact.

A geological estimate for the Afton area.
Typical Well Depth
Static Water Level
Recommended Method
The representative profile for Afton, synthesized from well logs in the area, shows an upper zone of mixed soil and silty sand/gravel (often 0-6 ft), grading into thicker intervals (to ~60 ft) of interbedded silt, clay, and fine sand. Below this, a more permeable gravelly sand to coarse sand and gravel sequence (often water-bearing) is usually encountered between ~60-130 ft, which is commonly targeted for residential water supply (with yields of 5-15+ GPM). Bedrock (limestone or basalt) is typically reached between 120-160 ft; deeper, high-capacity wells may be completed into fractured bedrock. The static water level is most commonly reported between 25-55 ft. Wells are usually drilled with rotary mud circulation, cased from surface to at least the uppermost gravel zones, and grouted with cement.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 6 ft | Soil/Gravel | Topsoil, occasional gravel/loam with minor silt | Color: Brown/gray Hardness: Soft |
6 – 60 ft | Silty Clay and Fine Sand | Silty clay with thin beds of sand and silt, some gravels | Color: Gray, brown, tan Hardness: Firm |
60 – 130 ft | Sand and Gravel (Water-Bearing) | Coarse sand, gravel, minor cobbles; major water yielding zone | Color: Gray, tan Hardness: Loose to medium |
130 – 160 ft | Fractured Bedrock (Limestone/Basalt) | Weathered to fractured limestone or basalt, occasional clay seams | Color: Gray-black Hardness: Hard |
