Geology 776

GEOL 776
Contaminant Transport

Catalog Entry

GEOL 776. Contaminant Transport
Three hours lecture/discussion (3).

Prerequisites: Graduate standing and GEOL 675 (Advanced Physical Hydrogeology) and GEOL 676 (Introduction to Groundwater Modeling) or the consent of the instructor.

As the capstone course in the hydrogeology sequence, this course combines elements of the core hydrogeology classes to cover the hydrogeologic factors associated with protection of groundwater. Topics covered include advection, diffusion, dispersion, retardation, decay, and their use in the advection-dispersion equation. Fate and transport models and aquifer remediation techniques will also be studied.

 

Detailed Description of Content of the Course

The course is designed as the capstone course in the hydrogeology sequence within the comprehensive graduate-level study of environmental and engineering geosciences. The topics and concepts addressed in this course includes:

1. Understanding of the governing equations of groundwater flow.
2. Understanding of mass transport in saturated media, including transport through concentration gradients, advection, and dispersion.
3. Understanding of the complexities of dispersive processes.
4. Understanding of the advection-dispersion equation.
5. Understanding of the transformation, retardation, and attenuation of solutes the subsurface.
6. Understanding of the basic transport codes, including MODPATH, MT3D, BIOPLUME, and SUTRA, in addition to analytical solutions of the advection-dispersion equation.
7. Understanding of flow and transport in the vadose zone.
8. Understanding of multi-phase flow, including the fate and transport of LNAPLs and DNAPLs.
9. Understanding of the fate of inorganic and organic chemicals in the subsurface.
10. Understanding of site remediation techniques including natural attenuation, pump and treat systems, air sparging, and bioremediation methods.
11. Understanding of the interaction between surface and ground waters with their geologic setting.

 

Detailed Description of the Conduct of Course

The course will consist of three hours of lecture each week. The lecture portion will cover topics in a structured progression, beginning with the development of the advection-dispersion equation, and proceeding to model increasingly complex solute transport systems. Homework problems will be assigned weekly and will consist of real-world subsurface contamination scenarios

 

Goals and Objectives of the Course

The general goals and objectives are:

1. To describe the derivation and use of the groundwater flow equation.
2. To describe the derivation and use of the advection-dispersion equation.
3. To describe the complexities of dispersive processes.
4. To describe the processes of transformation, retardation, and attenuation of solutes in the subsurface, including their inclusion in the advection-dispersion equation.
5. To describe and use numerical simulations of solute transport including analytical solutions and canned programs such as MT3D, SUTRA, and BIOPLUME.
6. To describe flow and transport processes in the vadose zone.
7. To describe multiphase flow, including the fate and transport of LNAPLs and DNAPLs.
8. To describe the fate of inorganic and organic chemicals in the subsurface.
9. To describe site remediation techniques.
10. To understand the philosophy behind solute transport report.

 

Assessment measures

There will be two examinations. These exams will be combined with grades from fairly short homework assignments and more involved modeling projects. Projects will be evaluated by the instructor on basis of the adequacy, completeness in presentation, organization and quality of the final modeling report.
