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 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.

Course Topics:

  • Gain an advantage in your next aquifer test by mastering state-of-the-art field and data analysis procedures
  • Find out how to differentiate laterally extensive sands from isolated sand bodies in a single boring
  • Discover new techniques for anticipating and resolving problems that may arise in aquifer tests
  • Obtain step-by-step instruction for field screening using the In-Situ Level TROLL and computerized analysis using AQTESOLV

Slug Testing:

  • Learn to select and apply appropriate slug test models for different hydrogeologic settings and well configurations
  • Maximize results from tests conducted in wells screened across the water tab
  • Find out how to recognize and account for the effects of noninstantaneous (noisy) test initiation and wellbore skin
  • Discover the latest strategies for designing, conducting and analyzing tests in high-K media including oscillatory responses
  • Gain knowledge of new approaches for decreasing test duration in low-K media
  • Master all aspects of data collection with the In-Situ Level TROLL
  • Obtain hands-on experience with AQTESOLV analyzing data from a wide range of geologic settings

Pumping Tests:

  • Learn to design, conduct and analyze pumping tests in confined, leaky, unconfined and fractured aquifers
  • Master strategies for dealing with variable pumping rates, wellbore storage, partial penetration, well losses, wellbore skin and other common issues
  • Discover powerful diagnostic methods including derivative analysis that help you select appropriate pumping test models
  • Gain an advantage by applying Agarwal's method for analysis of recovery data
  • Find out the best procedures for monitoring a pumping test with the Level TROLL
  • Master tips and tricks for using AQTESOLV to analyze constant-rate, step-drawdown and recovery test
