Well Drillers Near River Falls, Wisconsin

A geological estimate for the River Falls area.

Detailed Summary

In the River Falls region, representative wells consistently encounter a surficial unconsolidated zone (sand, gravel, or clay) from the surface to about 30-40 feet, occasionally a sandstone/sandrock layer to around 80-90 feet, then transition into limestone bedrock, which is typically the main aquifer and continues to the bottom of the wells. The wells reviewed show casing generally installed through unconsolidated material (usually from surface to 80-120 feet), with grout or bentonite seals in the upper 20 feet. Static water levels typically lie between 45 and 200 feet, averaging around 120-130 feet below ground. Residential wells (5-15+ GPM) most often finish around 140 feet, though deeper completions up to 270-280 feet are found in high-capacity or low-yield areas. The prevailing geological sequence is: (1) sand/gravel/clay (0-40 ft), (2) sandstone or sandrock (variable, up to 90 ft), (3) limestone/dolostone (main aquifer, 80+ ft to bottom).
