GEOL 416/516 - Hydrogeology

Course Objectives

After taking this course, you should be able to solve practical, quantitative problems related to groundwater supply and contamination and to analyze new hydrogeologic settings and predict the direction of groundwater flow and pathways for contaminant movement. You should be able to gather and analyze data and write reports about the hydrogeology of a site, and to critically read reports and articles related to hydrogeology and groundwater contamination.
