Who should attend:
This course is designed for ground water scientists and engineers, project managers, compliance program managers and remedial design managers.

This course begins with a brief overview of hydrogeologic principles of pumping and slug testing then continues at an advanced level throughout the course to cover the range of conditions typically encountered during field investigations.

Data analysis exercises include both simple and advanced pumping and slug test analyses to match the range of conditions typically encountered during field investigations.

What to Expect:
Expect to learn about the latest techniques of aquifer testing. A list of course attributes are listed on the following page:

What to Bring:

  • Bring your laptop computer, a calculator and any field forms that you normally use for aquifer testing.
  • You are also encouraged to bring your own slug and pumping test data. Instructors will QA/QC your analysis results if time permits.
  • Course attendees bringing personal laptops will download and install the AQTESOLV demo from www.aqtesolv.com before arriving at the course.
  • Bring high expectations. We strive to make this the premiere aquifer testing course. Plus, you can expect to have some light hearted humor and fun along the way.

Course Details

Conducting aquifer tests in complex hydrogeologic settings such as heterogeneous or fractured media often leads 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 hydrogeologic site characterization?

Midwest GeoSciences Group can help! We have designed a powerful two-day training course on aquifer testing design, field methods, and data analysis techniques featuring AQTESOLV and the In-Situ Level TROLL. This course will provide you with the knowledge to master aquifer testing from beginning to end--using world-class field equipment and aquifer test analysis software.

Bring Your Computer: Analyze data from a variety of hydrogeologic conditions and well configurations using AQTESOLV. Participants are welcomed to bring their own project data for analysis for QA/QC by the instructors.

  • The course is very thorough and the instruction followed by worked examples an excellent format. I loved the problem sets and the time allowed both before and after the workshop to go through the problems with the instructors. If you take advantage of that time (and I did, both ends!), you basically are getting one-on-one instruction from the gurus. That was amazing and well worth it!
