Katie Walton-Day
Katie is a Research Hydrologist with the USGS Colorado Water Science Center.
Katie is a research hydrologist and has worked at the U.S. Geological Survey located in Denver, Colorado for over 35 years. During this time her research has primarily focused on understanding the sources and mobility of trace metals associated with hard rock and uranium mineral deposits primarily in the western United States. A primary goal of her research is to provide science-based information to facilitate decisions about remediation in areas contaminated by historic mining practices. Recently she has begun developing communication products to broaden the audience for USGS scientific studies related to the environmental effects of uranium mining in the Grand Canyon region. Finally, her research has expanded into understanding the effects of harmful algal blooms in Colorado Reservoirs.
