An introduction to contaminant hydrogeology and mass transport processes in groundwater regimes. Topics include natural groundwater quality, sources of contamination, for example from mine waste, agriculture, saltwater intrusion, and industrial activities, and the processes and principles governing mass transport, including advection, dispersion and diffusion. The course also explores methodologies for site investigation as well as various remediation methods. Quantitative.
Groundwater contamination can be a significant environmental problem leading to degradation of the quality of fresh water both in the subsurface and where groundwater discharges to surface water bodies. This course introduces the basic principles of contaminant hydrogeology, including the geochemical properties of inorganic and organic contaminants and the processes and principles governing mass transport, including advection, dispersion and diffusion. The course also explores methodologies for site investigation as well as various remediation methods that have been developed to clean up groundwater. Transport of non-aqueous phase liquids /gases in the groundwater context is analogous to transport of oil and gas in petroleum reservoirs.
- Overview of Groundwater Contamination - types of contaminants, lab analysis, sources
- Inorganic Chemicals in Groundwater - chemical processes in the unsaturated and saturated zones, mixing, zonation, inorganic contaminants
- Organic Compounds in Groundwater - naming organics, properties of organics, chemical partitioning.
- Mass Transport in Saturated Media (concepts and equations for mass transport, analytical solutions, field measurements, scale dependence, plumes.
- Transformation, Retardation and Attenuation
- Monitoring and Sampling - Site characterization
- Flow and Mass Transport in the Vadose Zone
- Multiphase Flow
- Remediation Methods (overview)
One 2-hour lecture and one 3-hour laboratory each week. The assignments are based on the theory part of the course, and these will be distributed during lab time.
COURSE-LEVEL EDUCATIONAL GOALS:
Knowledge Development and Application – Demonstrate understanding of types of contaminants (inorganic, organic, radionuclide), sources of contamination, and the physical and chemical processes that control the fate and transport (mobility) of contaminants (liquids – dissolved and free phase, gases).
Knowledge Application: Apply knowledge to predict how contaminants will move in the subsurface, whether they will degrade, and how can they be cleaned up.
Scientific Methods: Employ scientifically-based approaches to obtain, analyze and interpret data (geological, geochemical, and hydrogeological) and critically evaluate the scientific findings.
Analytical Skills: Use analytical methods (calculations, graphing), laboratory experimental methods, and computational methods (numerical modeling using specialized software at an introductory level) to quantify fate and transport of a variety of contaminants within a groundwater system.Communication Skills: Write a proposal in response to a call for proposals for a particular contaminated site. Present the proposal orally.

ACADEMIC INTEGRITY: YOUR WORK, YOUR SUCCESS
SFU’s Academic Integrity website http://www.sfu.ca/students/academicintegrity.html is filled with information on what is meant by academic dishonesty, where you can find resources to help with your studies and the consequences of cheating. Check out the site for more information and videos that help explain the issues in plain English.
Each student is responsible for his or her conduct as it affects the university community. Academic dishonesty, in whatever form, is ultimately destructive of the values of the university. Furthermore, it is unfair and discouraging to the majority of students who pursue their studies honestly. Scholarly integrity is required of all members of the university. http://www.sfu.ca/policies/gazette/student/s10-01.html
