PART 1: Practical Guidelines to Get More From Your Test Data

Discover and learn the most up-to-date information about
aquifer pumping test techniques from some of the most
recognized authorities in ground water.

Aquifer Pumping Tests are a key element to site characterization, water resources assessment and remediation system design. Even when you are confident of the geologic conditions, you may have difficulty designing effective aquifer tests, running field equipment or selecting the best available model to analyze the test data. Where do you turn for help with aquifer testing?

Midwest GeoSciences Group & In-Situ, Inc. can help! We have designed a powerful six-module webinar series about pumping test design, field methods and data analysis techniques.This course will highlight key steps for modernizing your aquifer testing from beginning to end.

PART ONE begins the series with introducing the conceptual design elements of aquifer pumping tests.

Each consecutive module builds upon the previous one, progressing with step drawdown tests for optimizing the constant rate pumping test, then presenting the principals of constant rate pumping tests followed by key elements of recovery testing when the pump is turned off. The webinar series continues with technical insights related to collecting continuous water levels, downloading the data, and then exporting it to analysis software. The last module is a practical and common application to unconfined conditions.

Webinar Outline and Highlights:
  1. Purpose
    1. in-situ estimation of large-scale hydraulic properties
      1. transmissivity (T) and storativity (S)
    2. hydraulic boundaries
    3. directional dependence
      1. dewatering
    4. conditions at pumping well
      1. pumping efficiency

  2. Mechanics
    1. pump well to produce change in water level (head)
    2. measure change (drawdown) at pumped and nearby wells
    3. analyze drawdown measurements

  3. General Design Guidelines
    1. Overall Goal
      1. Justify model selection
    2. Assess primary mechanisms
      1. Confidence in T and S estimates
    3. Key Elements
      1. Location of observation wells
      2. Pumping rate and duration
    4. Monitoring period
    5. Non-ideal conditions

  4. Overview of Analysis Methods
  5. Resources and Reference

Register now for this exclusive webinar series that presents key insights
about aquifer pumping tests that are found no where else online.

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.

Instructors Bio

Jim Butler 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 is author of many scientific papers and the popular book "The Design, Performance, and Analysis of Slug Tests," which examines a method commonly used during the investigation of ground-water-contamination sites.

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.
