- Abstract:
In this activity, students visit two sites to practice their field water sample collection and water quality assessment skills. They use a vertical well-water sampler and downhole water quality probes to measure groundwater conductivity, pH, and temperature at different depths in a landfill. Collected water conductivity data is contoured to map the distribution of a contaminant plume. Students then study acid mine drainage by using water quality meters to compare pH and conductivity values up and down stream of an open-pit mine. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.

- Abstract:
This field activity may be implemented during late winter or early spring when things have not quite thawed. From a frozen pond, students collect bathymetric data, measure water temperature and conductivity, locate ground-water inputs, and extract a sediment core. Back in the lab, they make hand and computer-contoured bathymetric maps, temperature and conductivity cross-sections, and run visual-core log, loss-on-ignition, and magnetic susceptibility tests. Then they draw conclusions about water movement in the pond, pond-water residence time, and the pond's depositional and hydrologic history. This activity is designed for upper-level undergraduate and graduate-level geohydrology courses. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.
