Well Drillers Near Aniwa, Wisconsin

A geological estimate for the Aniwa area.

Detailed Summary

Based on a synthesis of well logs in the Aniwa area, the most representative geological profile is a shallow, unconsolidated sand and gravel aquifer extending generally 10-60 ft bgs (below ground surface), underlain by a transition zone of decomposed/weathered granite (often clayey) to approximately 20–40 ft, grading into hard crystalline granite bedrock that continues to total drilled depths of 150–200+ ft. The most reliable groundwater supplies come from the sand/gravel or fractured/weathered bedrock interface. Wells in this area commonly use rotary mud drilling, are cased through the unconsolidated overburden, and grouted typically to 40 ft with cement. Residential wells targeting 5-15+ GPM are most often completed in the upper 100–200 ft.
