Well Drillers Near Rhinelander, Wisconsin

Rhinelander wells typically encounter caving sand, sand and gravel, and occasional fine or coarse sands with limited clay, overlying crystalline bedrock. Most residential wells are completed at 38–60 feet, with water-bearing zones primarily in unconsolidated sand and gravel.

Detailed Summary

Based on a synthesis of well logs from the Rhinelander area, the most representative geologic profile consists of an upper layer of caving sand (sometimes intermixed with gravel), transitioning to sand and gravel units (including both fine and coarse fractions), rarely with thin clay or silt interbeds, overlying granite or crystalline bedrock (sometimes as shallow as ~65 feet but only occasionally reached in residential wells). The static water level typically falls between 10 and 32 feet. Wells for typical residential use (to yield 5–15+ GPM) are generally completed at depths of 35–60 feet, cased almost to total depth and screened in coarse or mixed sand/gravel zones. High-capacity wells (rare in the sample set) may go deeper into coarse sand/gravel or potentially to bedrock if required.
