In this activity, students begin exploring the effectiveness of a remediation system installed at a closed landfill system. Students learn the importance of redox chemistry in a real-world context and build field sampling skills.
This exercise is used in an undergraduate course on environmental geochemistry.
Skills and concepts that students must have mastered
The following are useful, but not essential:
A lecture on redox chemistry
Proper water sampling techniques (especially if later trace metal analysis is a goal)
How the activity is situated in the course
This exercise is the first part of a sequence of exercises exploring the geochemistry of the closed landfill. After the field component of the exercise, students also explore this problem using GIS software and they work with lab data on the water samples they have collected.
Content/concepts goals for this activity
Understanding redox reactions and the factors that influence the behavior of contaminants in the surface environment.
Higher order thinking skills goals for this activity
Geochemical data analysis and preliminary interpretation
Other skills goals for this activity
Operating field analytical equipment, properly collecting water and sediment samples, working together
Description of the activity/assignment
Determining whether students have met the goals
In this exercise students are evaluated on the quality of their written responses to a set of discussion questions and on their contribution to field work. More information about assessment tools and techniques.
