Well Drillers Near Berlin, Wisconsin

A typical residential well in the Berlin 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 12 feet below the surface in this region.

Analysis of a cross-section of well logs for the greater Berlin, Wisconsin region shows that most wells encounter an upper layer of clay, sand, or sand and gravel to an average depth of about 40-60 feet. Underlying this, a variety of mixed coarse (sand, gravel) and fine (clay, silt) deposits predominate, typically extending to 60-125 feet, with some logs reporting these mixtures even deeper. The typical productive aquifer for private potable supply is medium to coarse sand or sand and gravel, often yielding 5-30 GPM within the first 40-80 feet, and most wells are cased through these unconsolidated deposits. Underlying these unconsolidated materials, most wells encounter sandstone or sandrock (sometimes described as brown, pink, or white) beginning between 55 and 125 feet, with the transition to shale or limestone in some locations appearing between 120 and 200 feet. For higher capacity or deep residential wells, drilling into the sandstone (and, locally, into underlying limestone/shale) is common to ensure adequate yield and water quality. Static water levels are typically shallow, averaging 6-15 feet below ground surface, indicating a reliable water table aquifer. Rotary mud circulation is the dominant drilling method. Wells are typically cased through unconsolidated material and grouted with neat cement or puddled clay to prevent surface contamination.
