Using state-of-the-art imaging tools for lower-cost investigations

Pete Chase, a geotechnician at University of Wisconsin–Extension’s Wisconsin Geological and Natural History Survey, uses borehole imaging equipment to collect high-resolution digital images of the subsurface at lower cost and with better results than ever before. Chase uses these tools as part of the Survey’s program for hydrogeology and geology research projects. He also uses these tools to assist municipal water utilities.

“Sometimes a water supply well will act up. One good way to figure out the problem is to drop our camera and other tools down the well to literally take a look. We work with municipalities and their consultants to get answers fast—and to get their wells back up and running,” said Pete.

The tools are being used in a variety of externally funded short-term research projects, long-term interpretive geologic studies, and for teaching and demonstration for students, drillers, and professional groups. The National Science Foundation (NSF) provided $101,200 for the purchase of this equipment and its software.
