ENVIRONMENTAL ISOTOPES FOR CONTAMINANT SOURCE IDENTIFICATION:
Advances in Tools, Technologies and Applications
Isotopes As A Key To Determining Contaminant Sources
Knowing the contaminant source is a fundamental requirement for remediation, and isotope investigations can be particularly helpful in determining the contaminant source in groundwater, surface water, and soil gas. This webinar presents case studies where isotopes were used to demonstrate:
- Common isotopes used in environmental investigations:
- Deuterium
- Oxygen-18
- Carbon-13
- Carbon-14
- Tritium
- Strontium
- Ntirogen-15 isotope of ammonia
- Natural and anthropogenic concentrations of these isotopes in the environment
- How isotope data is analyzed with respect to other geochemical data through:
- Time-series analysis
- Geochemical fingerprinting
- Isotope evaluation
The webinar will address:
- When isotope evaluation is appropriate
- Planning an isotope sampling and analytical event: the field sampling and analytical methods you need to know
- How to interpret isotope results
- How results can determine the appropriate remediation response
In addition, this webinar will discuss how isotopes are used to understand the origin of:
- VOCs in groundwater contaminated by leachate from hazardous waste and municipal solid waste landfills
- Methane in soil gases and dissolved gases in groundwater leading to VOC detections
- Ammonia-nitrogen in groundwater
- Ammonia-nitrogen from salt water and marine muds
- Inorganic contaminants in groundwater
Attendees are 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.

Instructors Bio
John Baker, MS-EE
John Baker has over 40 years experience in implementing new technologies for more cost effective remediation and optimization of hazardous, nuclear and solid waste landfills. He previously worked 23 years for Waste Management, Inc. most recently as the Director of New Technology. In this role, Mr. Baker was responsible for developing innovative methods for environmental assessment including forensic contaminant sources for gas and liquids using geochemistry and environmental isotopes.
Mr. Baker has also developed advanced remediation techniques and enhanced renewable energy production of active and closed landfills. Mr. Baker has evaluated over 200 innovative waste management technologies for energy production including pyrolysis, gasification, plasma arc, and other treatment/conversion methods. Technical feasibility and relative economics were included. Mr. Baker also was involved in early research starting in the late '70s with DOE and USEPA for potential of pyrolysis and gasification for waste to energy and remediation. He also assisted in permitting a plasma arc hazardous waste incinerator in the early '80s. Mr. Baker also provided consulting services for two gasification companies for citing and start-up demonstrations using MSW.
BS in Biology/Chemistry and MS in Environmental Engineering from University of Illinois, Urbana, IL 1971 & 1973
