Typical Richmond-area wells encounter alternating clay and sand/gravel layers to depths of 100–125 ft, with water-bearing sands generally located below 30–45 ft and/or at greater depths. Residential wells for 5–15+ GPM are typically 80–125 ft deep.

Recommended Method
The representative geology for the Richmond region consists of an upper sequence of 10–24 ft of clay or clay with some gravel, followed by interbedded sandy or gravelly intervals and additional clay layers. The most consistent pattern is: initial clay (10–24 ft), then sand or sandy gravel (few to ~8 ft), followed by more clay (sometimes extending to ~78–118 ft). Deeper water-bearing zones, usually coarse sand or sand/gravel, are typically found below 80–100 ft and can run to total well depths of 100–125 ft. Static water levels range from 5 to 45 ft below grade. Most wells use rotary mud circulation and are cased with 4–5 in. PVC to near total depth, with screens set at the bottom in coarser, water-bearing material. Typical residential well depths for 5–15+ GPM yield are 80–110 ft, with higher-capacity wells possible down to 125 ft.
