Well Drillers Near Canton, South Dakota

A geological estimate for the Canton area.

Detailed Summary

The typical Canton, SD region geologic profile (based on synthesis of logs from public supply, irrigation, and monitoring wells) begins with a thin topsoil or silt layer, followed by variable brown or light brown fine sand, silty sand, or clay (0–7 ft). Most wells then penetrate a thicker sequence of sand and gravel (usually with clean or brown/gray hues) from about 7 to 54 ft, which forms the main water-bearing aquifer for both residential and high-capacity supply. Below the main aquifer, blue-gray to greenish clay, clayey sand, and intermittent gravel layers extend typically to 250–300 ft. Deeper test or municipal wells show continued interbedded clays and sands to 350+ ft, below which Cretaceous bedrock (shale, quartzite) is reached around 390–400 ft or deeper. Slight local variations (occasional cemented sand, cherty gravel, or silt zones) exist but are not persistent enough to characterize the area. A typical residential water well penetrates 40–90 ft for reliable 5–15+ GPM yields, while high-capacity wells may go 180–250+ ft for greater draw.
