LSP Association Continuing Education Seminar

Pneumatic Slug Testing

When: Online Anytime - take this course anytime, for 4 hours or more, online at your convenience.
Location: Virtual Groundwater Academy
Instructor: Gary A. Robbins, Ph.D., Ram's Horn Educational, LLC. 
Pricing: $179

Course Description:

This course provides participants with the knowledge and experience to calculate hydraulic conductivity using pneumatic slug testing. Emphasis is given to testing high permeability formations that exhibit an oscillatory slug test response.

Slug testing in wells has become the method of choice for assessing hydraulic conductivity at contaminated sites owing to its low cost and simplicity of implementation, and to the fact that little to no contaminated water need be handled. This course provides an opportunity to learn how to properly conduct pneumatic slug tests, how to analyze slug test data, and how to interpret the results. This is achieved through a review of slide presentation material, conducting "hands-on" pneumatic slug testing simulations in virtual space, analyzing data collected using spreadsheets, and discussion with the instructor as needed.

More Information

The slide presentation focuses on how tests are performed, critical factors influencing tests, test limitations and sources of error, and how to choose the appropriate test method and solution. At critical points in the slide presentation, participants will conduct slug test simulations that mimic real world testing and analyze the data obtained using spreadsheets. They will conduct a “virtual” conventional slug test for review, as well as simulations of a pneumatic over-damped slug test and a pneumatic under-damped slug test. Data analysis is conducted using provided spreadsheets. Participants may also download a demo version of commercial software to use in analyzing data.

Please note: you will receive a separate confirmation email with your course link and key code on the day you register. If you register outside of the hours of 9AM and 5PM, Monday through Friday, you will receive this information on the next business day.
