ABAS, em parceria com a University of Waterloo, promove o Curso de Contaminantes Orgânicos

Organization: Brazilian Groundwater Association (ABAS) and University of Waterloo
Date: 15 January to 02 April 2010


University of Waterloo is one of the main excellence centers in groundwater sciences.  For many years, this University has been preparing highly-skilled professionals who work in different parts of the world. One of the main courses offered for its graduate students is the Organic Contaminants Course, which presents a solid theoretical basis and the state of the art in this area of knowledge. This course now is open to the public, not only for UW graduate students. It is an ideal course experience, considering the amount of experience gained for the hours invested. Although it is a high-level course, it can be easily followed by professionals from different backgrounds, as proven by several students who already have been through this institution.

The objective of this course is to promote knowledge exchange of modern characterization and remediation techniques for groundwater contaminated by organic compounds.


Professionals dealing with groundwater, hydrogeologists, engineers, geologists, chemists, biologists, project managers, consultants, regulatory agents and environmental professionals in general.


Jim Barker: Jim Barker holds a PhD from the University of Waterloo where he has been a faculty member in the Earth Sciences Department since 1979. Jim’s research has concentrated on the migration, fate, and remediation of organic contaminants in groundwater and he uses field studies at contaminated sites and at the research aquifer site at Canadian Forces Base Borden. Current research is focused on the critical evaluation of monitored natural attenuation and in situ groundwater remedial technologies.

Everton de Oliveira: Everton de Oliveira is a geologist, and holds a PhD from the University of Waterloo. He is a past president of ABAS (Brazilian Groundwater Association and is a partner in the Hidroplan Consultant Company. He participates as a visiting professor in the University of Waterloo and in courses offered by the Brazilian Petroleum Institute and CETESB (São Paulo State Environmental Agency).  Everton has more than 18 years of experience in the assessment and remediation of contaminated sites.
Lai Gui: Dr. Gui is a Research Scientists with Health Canada and a former Research Assistant Professor in the Department of Earth Sciences, University of Waterloo. Her research has been focused on understanding of chemical and biological degradation processes of groundwater contaminants, with a particular emphasis on the use of granular iron for in situ remediation. Dr. Gui has a doctoral degree in Environmental Engineering from the Johns Hopkins University, U.S.A. and a M.Sc. degree in Soil and Water Management from Wageningen University, the Netherlands.

Ramon Aravena: Ramon Aravena is a Research Professor in the Department of Earth Sciences, University of Waterloo, with 20 years experience in the application of isotope and geochemical techniques in hydrology. He has been involved in numerous ground water studies in Brazil, Latin America, Canada and the U.S. related to evaluation of ground water resources and ground water protection. His current research focuses on ground water contamination caused by agricultural and urban activities.

Neil Thomson: Dr. Neil R. Thomson is a Professor in the Department of Civil and Environmental Engineering at the University of Waterloo.  Dr. Thomson has over twenty years of research experience and expertise in the use of field investigations, laboratory experiments and numerical models to explore subsurface contaminant fate and remediation issues.  Dr. Thomson's current research interests are focused on: the environmental fate of contaminants in subsurface systems including immiscible liquids, vapours, and pathogens; the development and application of simulation tools; and the development and assessment of soil and ground water remediation technologies.

Barb Butler: (PhD, Waterloo) is a Lecturer in the Department of Biology, University of Waterloo. She is an environmental microbiologist and collaborated on projects concerning contaminated groundwater environments (1990-2003). Currently, her primary role is undergraduate teaching, but she maintains research interests in biotransformation of organic contaminants in soil and groundwater systems, and the role of ciliates in aquatic systems.

Coordinators Juliana Freitas and Marcelo Sousa: Juliana Freitas holds a Ph D from Waterloo (2009), an M.Sc. in Sanitary Engineering and a B.Sc. in Civil Engineering from the University of Sao Paulo and is currently a Postdoctorate Fellow in the University of Waterloo. Marcelo Sousa graduated in Civil Engineering from the University of Sao Paulo and is currently a Ph D candidate in the University of Waterloo.


Thirty-six hours of lectures, plus at least 12 hours of tutorial/discussion will be provided over the twelve-week course. At least one lecture and one tutorial will be provided in Sao Paulo. Topics include:

  • Fundamental processes governing the fate of organic contaminants in soil and aquifer systems. Emphasis on partitioning between phases (dissolution, sorption and volatilization) with applications.
  • The behaviour of Non-Aqueous-Phase-Liquids (both LNAPLs and DNAPLs) in the subsurface.
  • Chemical transformations, including hydrolysis, kinetics and redox reactions.
  • Biological processes and contaminant biotransformations. Field evidences of biotransformation.
  • Effects of cosolvents on the fate of contaminants, focusing on ethanol.
  • Bioaugmentation, sparging and in-situ chemical oxidation as remedial techniques.
  • Isotopes applications in field studies of organic contaminants.
  • Modeling of organic contaminant migration, fate and remediation.


Lecture material (power point lecture notes and assignments) will be available on a ftp web site the day before the lecture. The lecture can be joined by Skype at 12:30 to 15:30 on Friday. A video record of the lecture will also be made available within 1 week of the lecture. Occasional lectures and meetings with students will be given in Sao Paulo and a lecturer or coordinator will hold at least one, 3 hour tutorial in Sao Paulo related to the assignments and course material.


Students will complete and receive feedback on three small assignments and one major assignment requiring the student to assemble environmental information about two organic contaminants and to assess potential remedial technologies for two site conditions. Successful completion of these assignments will result in the University of Waterloo issuing a certificate of course completion.
