Course Details

Conducting aquifer tests in complex hydrogeologic settings such as heterogeneous or fractured media is a key element to site characterization, water resources assessment and remediation system design. However, poorly planned aquifer testing programs often lead to suspect data or unanswered questions after the field work is complete. 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 can you turn to improve your approach and skills for aquifer testing?

Midwest GeoSciences Group can help! We have designed a powerful three-day training course on aquifer testing design, field methods and data analysis techniques featuring AQTESOLV. This course will provide you with the knowledge to master aquifer testing from beginning to end. Gain an advantage by learning up-to-date methods and procedures for designing, conducting and analyzing aquifer tests.

You are invited to Baltimore, Maryland for an exciting three-day workshop on Advanced Aquifer Testing Techniques Featuring AQTESOLV: New Concepts, Field Methods and Data Analysis Procedures. This unique and practical course, designed for hydrogeologists and engineers of all experience levels, will be taught by three internationally-recognized leaders in the field: Glenn Duffield, author of AQTESOLV for Windows; Jim Butler, author of The Design, Performance and Analysis of Slug Tests; and Shlomo Neuman, principal author of numerous landmark papers on the analysis of pumping tests in multilayer aquifer systems, unconfined aquifers with delayed gravity response and fractured aquifers.

Outline & Objectives

This course covers fundamental methods of aquifer testing as well as innovative new approaches to field and data-analysis procedures. Some of the questions that we will address in this course include the following:

  • What are the advantages and disadvantages of pumping tests versus slug tests?
  • How do I translate hydrogeologic conditions encountered in the field into a model for a slug test or pumping test?
  • How do I account for well loss and determine well efficiency from a step-drawdown test?
  • How do I analyze a slug test in a high-K aquifer that exhibits an oscillatory response?
  • What methods are available for analyzing pumping tests in fractured bedrock aquifers andhow do I apply them?
  • What are the latest guidelines for designing, conducting and analyzing slug tests in wells screened across the water table?
  • What is the wellbore storage effect and when is it important to account for it?
  • Can I use AQTESOLV to design my pumping test or slug test?
  • What are constant-head tests and how do I analyze them?
  • What testing and analysis procedures are available for characterizing heterogeneous aquifers?
  • What is the best method to account for noninstantaneous (noisy) slug test initiation?
  • How do I get the most out of the AQTESOLV software?

This course demonstrates ways in which these questions can be answered by understanding and improving the design of pumping and slug testing, learning meaningful field methods, and practicing appropriate data analysis using AQTESOLV.

You will enjoy personalized instruction from Glenn Duffield, Jim Butler and Shlomo Neuman who have designed a comprehensive course for all types of ground water professionals. This course is unique because it covers new and updated material focusing on constant and variable-rate pumping tests, single and multiple-well tests, tests in fractured rocks, derivative plots, and much more. Participants are encouraged to bring their own datasets and notebook computers for use on example problems.
