Presentation Videos

The U.S. Geological Survey (USGS), Eastern Region, held a workshop on mercury in August 2004. Presentations were made by 29 individuals representing four federal agencies in addition to the USGS, one state agency, one Native American Tribe, and five academic and research institutions. The presentations, through video and slides download, are being made available on this web site for informational purposes only.
