Introduction:
Attendees will gain an advantage by improving their hydrogeologic analysis and understanding remediation techniques of fractured bedrock, including carbonate, crystalline, and metamorphic rocks. The first day consists of real-world applications for evaluating the role of bedrock fractures in ground-water movement and contaminant transport. Special attention will be given to the inherent difficulties of ground water modeling in fractured bedrock systems. Participants will learn and practice describing rock core for hydrogeologic projects and estimating core recovery and Rock Quality Designation (RQD). The second day includes exclusive access to the Nevada Test Site with an extended view of the proposed Yucca Mountain Repository Area. The third and fourth days include a comprehensive comparison of different hydrogeologic field tests and analytical methods for characterizing aquifer properties. In addition, the latest techniques for designing ground water monitoring systems and remediation systems in fractured systems will be presented. Course participants are encouraged to bring their own problems for discussion by the entire group.
This four-day workshop updates procedures for modern, state of the art, hydrogeologic analysis of fractured bedrock systems. It will include the following topics:
- Nature of Rock discontinuities and fracture flow
- Field-proven techniques for measuring and describing fracture networks
- Integrating rock stratigraphy into conceptual models
- Hands-on description of various rock cores
- Measurements of core recovery and RQD
- Dual porosity and discrete fracture conceptual models
- Equivalent porous media approximations and their validity

- This is a highly practical course in fractured bedrock. I attended this course prior to beginning a large investigation at a site situated in a complex fractured rock setting. The course was an invaluable aid in planning the design of the components of the intrusive investigation and analysis of the field data. ...this is the most up-to-date and functional course that I have attended in years.
- S.C. Blauvelt, P.G., Vice President & Director of Regional Operations, Penn E&R, Inc.
- This was an excellent course with highly qualified instructors, up-to-date course material on fractured rock hydrogeology, and an outstanding field trip inside Yucca Mountain at the Nevada Test Site. I highly recommend (this course) to any geologists, environmental scientists, and engineers.
- Scott Shelton, City of Boston
- The course instructors had the right mix of theoretical expertise, practical experience, and enthusiasm. Also, the course instructors facilitated great interaction among the attendees which was an unexpected benefit of this course. It was well balanced and in-depth educational experience that was well worth my time and expense. It validated some of my own applications of fractured rock theory to LNAPLs, and gave me a better understanding with new tools to move forward in this area of hydrogeology.
- Don Lundy, ESNT, Inc.
- This course is an excellent overview of fracture flow coupled with new concepts of contaminant and fluid flow in fractured media. Not only does the course explain porosity & permeability of fractured settings, but it presents useful modeling approaches for fractured scenarios too. The instructors are terrific and highly knowledgeable in their field of study. The field trip to Yucca Mountain was the highlight of the course. I would recommend this course to anyone working with groundwater, ranging from contaminant assessments to water supply.
- Christine Bucklin, California Department of Toxic Substances Control
- A fantastic mix of knowledgeable and enthusiastic instructors, up-to-date and expansive course materials, and one spectacular field trip made this by far the best course I have attended.
- Kathleen T. Soukup, Weston Solutions, Inc.
- The course was excellent because of the combined classroom material and core logging - I can apply the course material immediately.
- Jami Poor, Kerr-McGee Corporation
- The combination and cohesiveness of the classroom, core logging practice, and Yucca Mountain field trip makes this a first rate and unique course.
