ANAEROBIC ATTENUATION OF PETROLEUM CONTAMINATION:
Advances and New Trends in Natural Attenuation

Anaerobic degradation is the dominant driving force in natural attenuation of petroleum contamination in the subsurface. The contribution to natural attenuation by electron acceptors other than oxygen, such as nitrate, iron III, manganese IV, sulfate, and even carbon dioxide, has been the subject of considerable research in recent years. Bruce (2007), Kolhatkar et al. (2000), Wiedemeier et al. (1999), and Wilson et al. (2002) have shown that of these natural anaerobic processes, sulfate reduction accounts for most of the degradation because of its natural abundance in groundwater. The use of these alternative electron acceptors has been shown to have many potential advantages over the traditional approach of attempting to add dissolved oxygen to a plume.

This Webinar is an Applied Introduction to New Trends in Anaerobic Attenuation

This 90-minute seminar will present data to show the dominance of anaerobic processes. It will define simple and relatively inexpensive geochemical methods for determining what attenuation processes are active in a plume, and whether or not enhancement through electron addition is likely to increase degradation rates. Lastly it will present a mass balance method of estimating the amount of electron acceptor compounds that may be required to degrade a given contaminant source.

Pay one site (one computer) registration fee and an unlimited number of participants from your organization can attend at that site.

Participants will receive a handout referencing the webinar topics and discussion.

1.0 Professional Development Hour (1.0 PDH) for each verified attendee will be available as a Course Completion Certificate from Northern Illinois University.

Attendees will be invited to actively participate during this live and interactive on-line web seminar. Discussion is planned following the webinar for those who want to continue the session. Bring your questions to the webinar and present them to the instructor and other participants for exploring the best solution.

Instructor Bio
Dr. Lyle G. Bruce has over 35 years of geologic experience. For the last twenty years he has worked for BP (Amoco) focusing on investigating petroleum and petrochemical contamination in soil and groundwater, identifying and fingerprinting products, and providing solutions for remediation and cleanup. Prior to entering the fields of hydrogeology and environmental geology, Dr. Bruce was an exploration geologist for 15 years. He has an M.S. from The Ohio State University and a Ph.D. from Oklahoma State University. After 20 years in remediation management, Dr. Bruce retired from BP in August, 2009 and founded L. G. Bruce Consulting.
