Get the Lead Out!

An Interdisciplinary Case Study

By Laurie LeBlanc, Robert Mazalewski, Jonathan Cook, Jasmine King

Get the Lead Out!


 

Abstract

This case study, developed for a general chemistry course, is intended to teach students the interdisciplinary nature of environmental science. Students take on the role of environmental chemists.  Using atomic absorption spectroscopy, they test for lead contamination in groundwater samples taken from an old mining district in Lake County, Colorado. After researching remediation methods, students propose practical solutions to local soil contamination.
