Well Drillers Near Plainfield, Wisconsin

A typical residential well in the Plainfield area is drilled to approximately 110 feet to ensure a reliable water supply of 5-15+ gallons per minute.

The static water level, or water table, is typically found around 35 feet below the surface in this region.

Based on a representative sample of well construction logs in the greater Plainfield area, the geology is overwhelmingly dominated by thick sand and gravel deposits (often 60–120 feet thick), sometimes with a shallow topsoil or organic horizon. Occasional clay or gravelly clay layers (typically 5–10 feet thick) occur between about 50–130 feet in some locations but are not everywhere present. Below about 100–140 feet, logs show either coarser sand, gravel, or transition into finer sand/sandstone units. The principal residential aquifer is the sand and gravel, which yields high water quantities (commonly 5–30+ gpm at static levels 15–50 feet but can be deeper). High-capacity wells may penetrate to 150–210 feet and may enter sandstone units. Grout/casing practices standardize protection for the upper 60–130 feet, consistent with regulations.
