Practical Tracer Testing Techniques for Site Characterization and Remedatiation System Design

June 6, 2013 (8AM - NOON)



Tracers have been broadly utilized in hydrogeologic and hydrologic studies for many years to understand solute transport phenomena in porous media and fractured rock aquifers.  However, until recently, tracers were mostly used in research settings and only infrequently employed by consultants and practitioners at typical contaminated sites. This shift is in large part due to the recognition that the success of many in situ remedial strategies is tied to local scale hydrogeologic conditions, reagent distribution, and contaminant transport behavior.  Consequently, tracers are increasingly becoming a standard and cost effective hydrogeologic characterization tool used by consultants to obtain basic aquifer characterization information and support development of conceptual site models, calibration of numerical flow and transport models, evaluation of contaminant-related risk, and remediation system design and assessment.

This workshop will focus on the practical use and application of tracers by practitioners at remediation sites.  Specifically, the material will include guidance on the use of tracers to characterize aquifer injectability, understand reagent distribution and utilization, quantify contaminant transport and degradation, and provide a basis for the design and optimization of in-situ remediation systems.  Additionally, the course will highlight examples of how tracers can be used to measure contaminant flux, assess LNAPL mobility, and evaluate hydraulic capture.  The course will cover basic terminology and concepts, tracer materials and analytical methods, health, safety and regulatory issues, test design and data interpretation concepts, and specialized applications and new developments.

Registration begins at 7:30 AM and the class begins at 8:00 AM. Course sessions are from 8:00 AM to Noon.

Dr. Craig Divine is a Principal Hydrogeologist and Technical Expert with ARCADIS (Highlands Ranch, Colorado) with more than 15 years of experience in hydrogeology and hydrogeochemistry.  Dr. Divine has particular expertise is in the design and analysis of applied tracer tests and has chaired topical sessions at national conferences, given numerous presentations, and written peer-reviewed journal articles regarding tracer testing methods and applications. Dr. Divine has designed and reviewed hundreds of tracer studies to support site characterization and remediation system design and operation and has lead the development of numerous innovations in tracer technology and application.

Dr. Elizabeth Cohen is a Chemical Engineer with a PhD in Environmental Chemistry. She has consulting experience in geochemistry and hydrogeology in Australia and the United States. Currently, Dr. Reece is an Environmental Scientist with ARCADIS in Novi, Michigan. Dr. Reece’s experience with tracers covers use in pristine and natural systems as well as a tool for characterization of contaminated sites and remediation design. She has significant experience in the use of both applied (fluorescent dyes, salts, deuterated water, dissolved gas) and environmental (isotopes, geochemical data) tracers both at a field level and during the planning, implementation, and data interpretation phases.



The course will be held in the Berthoud Hall. The Berthoud Hall (1516 Illinois St. Golden CO 80401) is located on the corner of 16th and Illinois Streets, and #5 on the campus map below.

All Visitor parking areas will have a pay and display parking meter. When arriving on campus for the first time, look for a parking meter, find a space in that location, pay the meter and display the receipt on your dash. You will find brochures at each of our parking meters that can also help guide you around the campus.



The fee for the short course is $295 by 4PM Mountain Daylight Time, May 23, 2013 ($345 after May 23).  You will be invoiced for the tuition balance. The fee covers instruction, course notes, refreshments, and continuing education units. Lodging and meals are not covered. Payment in full must be received prior to the beginning of the course. The registration fee may be paid by check, VISA, MasterCard, AMEX, Discover or purchase order (US Only). A maximum of 20 applicants will be able to attend the course due to space limitations.

If cancellation is made before May 23, 2013, tuition will be refunded except for the $100 deposit. In case of cancellation, the right to course material is forfeited. Substitutions are permitted at any time prior to the start of the course. Please be advised that if the program is cancelled due to insufficient enrollment, Colorado School of Mines will return all course fees, but will not be liable for any other expenses incurred by the prospective attendees.
