Well Drillers Near Brookfield, Wisconsin

A geological estimate for the Brookfield area.

Detailed Summary

Based on a synthesis of the sampled well logs from the greater Brookfield region, the representative geological profile consists of an upper unconsolidated clay (brown/blue) or hardpan, overlying thick sequences of sand and gravel (occasionally with interbeds of clay or hardpan), and in some areas followed by limestone or shale bedrock at depth. The majority of productive residential wells target the sand/gravel zones or the top of limestone, with typical casing set through the most unconsolidated intervals. Average static water levels are moderate (20-40 ft bgs), and standard residential well completions target a total depth of approximately 125-200 ft, while higher capacity wells may extend to 250+ ft. Casing is typically set through all unconsolidated overburden. Drilling is most commonly by rotary mud circulation, and grouting is generally with bentonite or cement.
