PUMPING TESTS FOR AQUIFER EVALUATION: Part 1:
Some Practical Guidelines to Get More from Your Test Data

Part One of a Comprehensive 4-Part Webinar Series on Aquifer Pumping Tests

This 90 minute webinar is designed to give consulting scientists and engineers and regulators the information they need to get reliable information from pumping tests.

Pumping tests are commonly used at sites for acquiring information about the transmissive properties and hydraulic boundary conditions of subsurface units. Unfortunately, much of the information currently obtained from pumping tests is of questionable quality as a result of inappropriate field and analysis procedures.

Webinar attendees will learn practical guidelines that they can apply immediately to their work to significantly improve the quality of parameter estimates obtained from pumping tests.

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 both slug testing and pumping tests.

Part 1 Webinar Outline and Highlights:

  • Purpose
    • in-situ estimation of large-scale hydraulic properties
      • transmissivity (T) and storativity (S)
    • hydraulic boundaries
    • directional dependence
      • dewatering
    • conditions at pumping well
      • pumping efficiency
  • Mechanics
    • pump well to produce change in water level (head)
    • measure change (drawdown) at pumped and nearby wells
    • analyze drawdown measurements
  • General Design Guidelines
    • Overall Goal
      • Justify model selection
    • Assess primary mechanisms
      • Confidence in T and S estimates
    • Key Elements
      • Location of observation wells
      • Pumping rate and duration
    • Monitoring period
    • Non-ideal conditions
  • Overview of Analysis Methods
  • Resources and Reference

Whether you want to apply aquifer pumping tests to hydrogeologic characterization, water supply development or remediation design, this webinar will provide attendees with information that is not available elsewhere on the web.

Here's what people are saying about Jim's past webinar:
"... I was able to see right away how Jim Butler's guidelines improve the efficiency and confidence in hydraulic conductivity test results. The presentation's clear graphics and on-site examples made this a practical learning experience, and I will certainly be able to implement these ideas both in the field and in analysis".
-Rachel McLean, AMEC Earth & Environmental


Instructor Bios
Jim Butler is author of many scientific papers and the popular book "The Design, Performance, and Analysis of Slug Tests," which is widely recognized as the key reference for slug testing.

Jim was the 2007 National Ground Water Association Distinguished Darcy Lecturer and the recipient of the 2009 Pioneers in Groundwater Award from the Environmental and Water Resources Institute of the American Society of Civil Engineers.

Jim's research includes aquifer testing, direct push hydraulic profiling, groundwater use by phreatophytes, and interactions between surface water and groundwater. Jim holds a B.S. in geology from the College of William and Mary, and M.S. and Ph.D. degrees in applied hydrogeology from Stanford University.

For the last 23 years, he has worked as an applied research hydrogeologist at the Kansas Geological Survey at the University of Kansas and is now the Section Chief of the Geohydrology Section there. He also is an Associate of the Center for East Asian Studies at the University of Kansas, a courtesy faculty member of the University of Kansas Department of Geology, and associate editor of "Hydrological Sciences Journal" and "Ground Water."
