Who should attend:
This intermediate to advanced course is designed for ground water scientists and engineers, project managers, compliance managers and water resources managers in the private, public and regulatory sectors. An fundamental understanding of ground water movement and geology considered as a prerequisite for this course. It will focus on recently developed concepts and technology.
Introduction:
Aquitards (low-hydraulic conductivity hydrogeologic units) are critically important to groundwater and contaminant movement. Characterizing aquitards for environmental and water resource projects is important for protecting deep aquifers and understanding potential contaminant pathways for previously impacted aquifers. Both unconsolidated and bedrock aquitards share inherent low hydraulic conductivities, but approaches and field methods for characterizing each type can be completely different. Appropriate characterization requires site-specific understanding about the aquitard's origin, unit distribution, heterogeneity, fracturing, and the effects of secondary weathering or tectonics.
We have designed a course to help you design and perform effective characterizations of aquitards for assessing ground water movement and contaminant migration. From basic hydraulics to comprehensive fracture analysis, this course addresses the practical aspects of hydrogeologic analysis for environmental, engineering and water resources projects..
- Improve your characterization of ground water movement & contaminant migration through aquitards by gaining a better understanding of aquitard hydraulics, vertical seepage, confining conditions and more
- Discover the importance of differentiating a sequence of low hydraulic conductivity units
- Discover new techniques and field instrumentation for monitoring aquitards
- Compare water sampling and slug test procedures in low hydraulic conductivity units
- Identify and characterize fractures from an angle boring using continuous rotasonic sampling
- Examine a regional bedrock aquitard and understand fracture distribution and mapping
- Explore new approaches for ground water and solute transport modeling in aquitards
- Gain better understanding about petroleum contamination in fine-grained sediments
- Understand the potential for pathogenic virus contamination in deep aquifers thought to be protected by overlying aquitards (plus a special workshop session on this growing subject)
This course features the most up-to-date information and procedures on petroleum (LNAPL) subsurface behavior, distribution and recoverability in fine-grained sediments. We will also cover recent advances in pathogenic virus contamination discovered in deep aquifers where the procedures for identifying, sampling, sample transport and lab testing is continually being updated and improved. Join us in September for this unique one-of-a-kind course.
Fractures in Fine-Grained Glacial Deposits: Special Session:
:
Jointing in fine-grained glacial deposits (including till) will be addressed during a special workshop session. Attendees will learn about 3-D joint geometries and relationships of the joints to weathering zones in till and understand the differences between those joints and others associated with stress relief features such as lake bluff erosion, river bank erosion, and steep man-made excavations. Learn how professionals use a variety of techniques to identify and characterize fractures, macropores, and other discontinuities in aquitards. Share your successes and ideas during a special workshop session.

- Thank you for organizing and putting together such an exceptional course and top notch group of presenters. (My co-worker and I) talked about the course all the way home. The tools provided during the (Aquitard Course) will be a major contribution towards solving problems in low permeability formations and by taking a new approach at how we can look at the Geology beneath a particular sight. I know that the more we work with these tools, the better and easier it will become. Thanks again and I look forward to attending additional courses in the future.
- Bradley D. Nordberg, Sr. Hydrogeologist, Minnesota Pollution Control Agency
- As usual, just a wonderful (course).
- Julie Weatherington-Rice, Bennett & Williams, Inc.
- I attended this course in preparation for increasing my project responsibilities as a hydrogeologist. The material presented and training received is necessary for any hydrogeologist or engineer who is concerned about potential contaminant migration through aquitards in his/her work. This course, like all Midwest Geosciences courses, is very well organized and taught by top-notch instructors. I recommend this course to all environmental professionals who work with soil and groundwater contaminant fate and transport.
- Alan Stone, Hydrogeologist and Project Manager, Concord Engineering and Science, Inc.
- Great Course! The field (exercises) were great! The presentation on viruses was very interesting!
- Stephanie Handeland, Illinois Environmental Protection Agency
- (The course) made me look at aquitards in a new way ..as separate components based on (geologic) units instead of one 'whole' unit.
- Michael Summers, Illinois Environmental Protection Agency
- The entire course was very applicable to my daily projects. The discussions, open forum, and the hands on field work really shined.
- Jeremy Reynolds, Huff & Huff, Inc.
- Great course, notebook, instructors, and examples!
- Guilio Scarzella, AMEC, Inc.
- This very intensive and technical class was outstanding in every respect. This seminar involved problem solving, field work, and presentations. I would highly recommend this class to all hydrogeologists regardless of the program they serve.
- Brian Kalvelage, Senior Regional Hydrogeologist, Wisconsin Department of Natural Resources
- Everything was great...the (session about) glacial depositional environments cleared up some of (my questions) about glacial sediments. I enjoyed examining the sediment core and (learning) from the experts. Dr. Bradbury's presentation on aquitard integrity, fractures and their importance of controlling hydrogeology was extremely informative. The presentations on viruses in the GW and sinking LNAPLs were profound and all new to me.
- Karen Nelson, Illinois Environmental Protection Agency
- I felt all sections of the course contributed valuable information and resources.
- Stephen Williamson, Illinois Environmental Protection Agency
- The (aquitard course) was excellent, thank you!
