(at home or in the office)

Despite the popularity and frequency of slug testing, difficulties exist with design and analysis. Questions about field screening, data collection, and analysis strategies continue to challenge professionals.

Sometimes these challenges emerge because of the conceptually simple nature of slug testing, poor habits or lack of meaningful training. Many challenges can be easily overcome by simply learning the six key steps that make slug testing more reliable - and easier to do with confidence.

The slug test is currently the most common technique used at sites of groundwater contamination for acquiring information about the transmissive properties of subsurface units. Unfortunately, much information currently obtained from slug tests is of questionable quality as a result of inappropriate field and analysis procedures.

Participants will learn the basic steps as practical guidelines that they can apply immediately to their work to significantly improve the quality of parameter estimates obtained from slug tests.

Much of the field and theoretical research on slug tests over the last decade has been done by Jim Butler and colleagues. Jim's work is widely recognized by the academic, consulting, and regulatory communities as having led to significant advances in the state of the practice for slug testing.

This event includes an optional pre-session self-assessment and a proficiency test.

Attendees will be invited to actively participate during this live and interactive on-line web seminar. Discussion is planned following the webinar for those who want to continue the session. Bring your questions to the webinar and present them to the instructor and other participants for exploring the best solution.

Instructor Bio

Jim Butler, Ph.D.

Jim Butler is the author of "The Design, Performance, and Analysis of Slug Tests" (Second Edition). He currently is a Senior Scientist in the Geohydrology Section of the Kansas Geological Survey at the University of Kansas, where he has worked for over 30 years.

His research interests include aquifer testing, assessment of aquifers that support irrigated agriculture, high-resolution subsurface characterization, well responses to natural and anthropogenic stimuli, and the role of phreatophytes in stream-aquifer systems.

Jim holds a B.S. in Geology from the College of William and Mary, and a M.S. and Ph.D. in Applied Hydrogeology from Stanford University. Jim was the 2007 Darcy Distinguished Lecturer of the National Ground Water Association (NGWA), the 2009 Pioneers in Groundwater Award honoree by the American Society of Civil Engineers - Environmental and Water Resources Institute, and, most recently, the 2020 recipient of NGWA's M. King Hubbert Award.

Jim helps advance the environmental and engineering industry through teaching professionals about both slug testing and pumping tests. Jim has taught more than 40 courses with Midwest GeoSciences Group. This webinar is another step toward that advancement and we are grateful to have Jim Butler teach this purposeful and applied webinar.
