Well Drillers Near Plainfield, Wisconsin

Plainfield area wells commonly encounter a thick sequence of unconsolidated sand and gravel, often interbedded with minor clay, overlying fine sand and sometimes sandstone. Most residential wells are completed entirely in sand and gravel aquifers by about 100–130 feet, with static water levels typically 15–50 feet but sometimes deeper.

Detailed Summary

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.
