Abstract:

Abstract: Twenty monitoring wells were installed in the fine-grained glacial of the Oak Creek Formation in southeastern Wisconsin to evaluate the effects of piezometer construction, installation, and development on the calculated formation hydraulic conductivity and well-water turbidity. The types of well screens used in construction of the piezometer were factory slot, factory slot with filter wrap, continuous slot, and porous stone tips. Some of the wells were installed after the borehole began to fill with water while others were installed in essentially dry boreholes. About half of the wells were developed by surging while others were developed only by bailing.
