Well Drillers Near Park Falls, Wisconsin

A geological estimate for the Park Falls area.

Detailed Summary

In the Park Falls region, water wells generally encounter a sequence beginning with clay/hardpan (sometimes mixed with silt or hardpan) from the surface to approximately 50 ft. This is frequently underlain by sand and/or gravel layers ranging to 60–80 ft, though these units are sometimes more limited or intercalated. Below these unconsolidated deposits, crystalline granite bedrock occurs and is typically drilled into for final well completion. Static water levels most commonly fall between 13 and 45 ft below ground surface. Yields sufficient for residential use (5–15+ GPM) are ordinarily found at or just below the base of the sandy or gravelly zones, sometimes requiring drilling a short distance into the granite. Standard well construction uses steel casing set into the top of bedrock, with grout seals of bentonite or cement. High-capacity wells may be completed deeper into bedrock, but thick unconsolidated cover is typical.
