June 20 - 21, 2006, 8:30 A.M. to 5 P.M. (2 Days) | Courtyard Los Angeles Old Pasadena | 180 North Fair Oaks Avenue, Pasadena, California

Delmar Meeting Room | Hotel phone number: 1-626-403-7600

Instructor: Richard W. Hurst, PhD, Hurst & Associates, Inc.

Description: This course provides participants with an overview and introduction to how state-of-the-art forensic geochemical techniques can be integrated with site related data to resolve issues related to contaminant transport and associated risks. The course provides the fundamentals of forensic science, and addresses how forensic results have been used to apportion liability for cleanup/recovery costs, as well as identify those responsible for a contaminant release. The course is intended for any environmental, geotechnical, or engineering professional working with issues involving contaminated soil and groundwater.

About the Instructor: Richard W. Hurst received his Doctorate in Geology and Geochemistry from the University of California, Los Angeles in 1975. He joined the Faculty in the Department of Geological Sciences, California State University, Los Angeles in 1978. His research efforts shifted, at that time, from investigations concerning the geochemical evolution of the early Earth, to the practical application of naturally occurring stable isotopes as tracers for contaminants in the environment. By 1980, he began consulting in forensic geochemistry, providing services to a diverse clientele in the private sector. His expertise in forensic isotope geochemistry, environmental forensics, and mineralogy is well known and respected in the academic, geotechnical, and legal communities. He is recognized for the development of the ALAS Model, a geochemical technique for estimating the age of gasoline releases, and for his exceptional ability to distill complex geological/geochemical data into a language that can be understood by non-technical professionals and students. He has developed university courses in forensic/environmental geochemistry and is currently writing a volume entitled Forensic Isotope Geochemistry for Elsevier Publishers.

 

After completing this course, participants will be able to:

- Identify methods available to resolve complex cases, such as those involving long term and/or multiple releases of contaminants
- Utilize information from general geochemistry of soil and groundwater analyses to assess sources of contamination
- Have an understanding of the uncertainties associated with various forensic techniques
- Assess methods of site remediation, such as bioremediation versus pump and treat
- Incorporate forensic geochemical techniques with those of contaminant hydrogeology, to better understand associated risk factors and apportion liability among responsible parties
