Well Drillers Near Portland, Michigan

A typical residential well in the Portland area is drilled to approximately 80 feet to ensure a reliable water supply of 5-15+ gallons per minute.

The static water level, or water table, is typically found around 30 feet below the surface in this region.

Analysis of multiple water well logs from the Portland, MI region shows a consistent stratigraphy: A surficial to near-surface clay layer (often interpreted as glacial till), typically 10–30 feet thick, underlain by heterogeneous sand/gravel or sand & clay mixtures, sometimes with thin secondary clay or gravelly lenses. This unconsolidated sequence generally extends to 60–100 feet, occasionally more, and is most often succeeded by consolidated bedrock (commonly sandstone and shale, sometimes interbedded) at depths of 90–100+ feet. Water-bearing zones are most commonly within the coarser sand, gravel, or mixed sand-gravel intervals. Most residential wells (supplying 10–15+ GPM) draw from these sand/gravel layers between 40–90 ft, or, in deeper wells, from fractured bedrock. High-capacity wells access the thicker bedrock aquifers at 200–275+ ft.
