For Hydrogeologic Projects

Packer testing is a technique in which one or more inflatable bladders, or packers, are used to isolate different regions of a borehole for hydraulic testing or water sampling. Although hydraulic packer testing is an "old" technology in the water well industry hydrogeologists often do not appreciate how valuable it can be in understanding and interpreting subsurface hydrostratigraphy, groundwater movement, and aquifer properties. Furthermore, many hydrogeologists do not completely understand the appropriate design, conduct, and interpretation of packer tests.

This webinar will introduce appropriate approaches, methods, and equipment for borehole packer testing applied to hydrogeologic projects. The course will feature step-by-step procedures for conducting tests, and will discuss various methods of test analysis.


  • Definition and types of packer testing
    • Single packer
    • Multiple packer
    • Permanent versus Temporary
  • Where is packer testing appropriate?
  • Choosing a packer setup
  • Types of hydraulic tests
  • Step-by-step guide to a packer test
    • Test objectives
    • Determining response time
    • Calculating inflation pressure
    • Instrumentation/data collection
    • Typical test responses
  • Methods of analysis
  • Two case studies


  • Learn where packer testing is, and is not, appropriate
  • Be exposed to modern packer equipment and monitoring instrumentation
  • Receive a step-by-step guide to conducting a test in the field
  • Learn analytical methods for interpreting packer tests
  • Learn to avoid common mistakes

Instructors Bio

Kenneth Bradbury, PhD, PG
( )

Ken Bradbury received his PhD in Geology from the UW-Madison in 1982, and has been a research hydrogeologist/professor with the Wisconsin Geological and Natural History Survey, University of Wisconsin-Extension, since that time. He serves as Program Leader of water and environmental programs for the Survey.

Ken's applied research includes groundwater flow in fractured media, aquitard hydrogeology, groundwater recharge processes, wellhead protection, and the hydrogeology of glacial deposits.

Ken is the author of numerous scientific papers and reports, is a Fellow in the Geological Society of America, has chaired the National Research Council Committee on Water Resources Research for the U.S. Geological Survey, and is a former member of the National Research Council's Water Science and Technology Board. In 2007 Ken undertook six weeks of research and teaching in South Africa and Zimbabwe supported by the Fulbright Senior Specialist Program.

Dave Hart PhD, PG

Dave Hart is a hydrogeologist/geophysicist with the Wisconsin Geological and Natural History Survey and an associate professor at the University of Wisconsin–Extension.

Dave's applied research includes regional groundwater flow and recharge in southeastern Wisconsin, near-surface geophysics, and measurement of porosities and permeabilities in aquifers and aquitards. Prior to joining the university, he served as a hydrogeologist with Eder Associates. He is an associate editor for Ground Water and past president of the AWRA – Wisconsin Section.
