Boise State has developed world-class expertise in studies of the Earth’s shallow subsurface
and in chemical analysis and characterization of geologic materials from around the world.
This research has applications for everything from cleaning up oil spills and identifying the
sources of surface water pollution, to understanding the consequences of climate change.
