Borehole geophysical logging for water-resources investigations in Pennsylvania Borehole geophysical logging for water-resources investigations in Pennsylvania

Borehole geophysical logging is a procedure to collect and transmit specific information about the geologic formations penetrated by a well by raising and lowering a set of probes or sondes that contain water-tight instruments in the well. The data collected can be used to determine general formation geology, fracture distribution, vertical borehole flow, and water-yielding capabilities.

Hydraulic conductivity of the streambed, east branch Grand Calumet River, northern Lake County, Indiana Hydraulic conductivity of the streambed, east branch Grand Calumet River, northern Lake County, Indiana

Horizontal and vertical hydraulic conductivity of the Streambed were estimated from results of hydraulic tests along four transects across the east branch Grand Calumet River in northern Lake County, Indiana. Tests were done in two types of temporary wells installed in the Streambed 2-inch-diameter wells that had a 1- or 2-foot length of wire-wrapped screen and 3-inch-diameter wells that...
