***Originally Aired January 3, 2016***
Jon Chorover is Professor and Department Head at the Department of Soil, Water, and Environmental Science at the University of Arizona.
He joins us to tell us about the important research he does into discovering how pollutants such as lead find their way into the soil and are released into the environment, whether as dust particles or into our water systems. Mine tailings are waste materials from hard-rock mining, and Chorover is researching phytostabilization, which allows for a vegetative "cap" on these tailings, keeping them "trapped" in the soil.
