The purpose of this course is to provide attendees knowledge and experience in determining hydraulic conductivity using pneumatic slug testing. Emphasis will be given to testing high permeable formations using small diameter wells that exhibit oscillatory slug test response. This objective will be met through lectures, hands-on field testing and computer assisted analyses.
Hydraulic conductivity at a contaminated site is the most critical hydrogeologic parameter influencing ground water flow and contaminant migration. The hydraulic conductivity is also a critical factor in determining risk and in deriving approaches to remediation. Slug testing in wells has become the method of choice to determine hydraulic conductivity at contaminated sites owing to its low cost, simplicity and that little to no contaminated water need be handled. Pneumatic slug testing offers means to also test high permeable formations and to test small diameter wells that exhibit oscillatory response. This course provides through lecture, hands-on field experience and computer assisted data analysis an opportunity to learn how to properly conduct pneumatic slug tests, how to analyze data and how to interpret the results. Special emphasis is given to the use of small diameter direct push wells and three-dimensional site characterization, and conducting tests in glacially derived sediment indicative of New England.
The course will entail 4 hours of lecture, 2 hours of field work and 2 hours of data analyses. The lectures focus is 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. The attendees will then conduct pneumatic slug tests in the field on the University of Connecticut campus in wells that exhibit non-oscillatory (overdamped) and oscillatory (underdamped) responses. Following the field testing, attendees will be analyzing their data using spreadsheets and commercially available software. We will then discuss results and related issues.
Dr. Gary Robbins is a Professor of Geology in the Department of Natural Resources and the Environment at the University of Connecticut in Storrs, CT. Professor Robbins is well known for his research work aimed at improving site investigations at contamination sites. Often called "the consultants consultant", he has offered training courses across the country for the private sector and the EPA. He is the author of Expedited Site Assessment: The CD, the recipient of a Contribution to Practice Award by the Massachusetts LSPA, the recipient of the University's Chancellor Information Technology Award, and is the 2016-2017 UCONN Teaching Innovation Awardee. Prior to coming to UConn he worked for Woodward-Clyde Consultants and before that the Nuclear Regulatory Commission. He has been called upon as a private consultant, expert witness and arbitrator for the private sector and government entities.
