Melinda L Erickson, PhD, PE

Dr. Melinda (Mindy) Erickson is a research hydrologist in the USGS Upper Midwest Water Science Center - Minnesota office. She is also an adjunct associate professor and Fellow at the University of Minnesota (Fellow, Institute on the Environment. Faculty member Department of Soil, Water, and Climate; Department of Bioproducts and Biosystems Engineering; and Water Resources Science).

I am a groundwater contaminant subject matter expert on several national and international interdisciplinary project teams. I have been working in the hydrogeology field since 1993, starting first in environmental consulting and then moving into groundwater-related research in 1998. I was a research scientist for the Minnesota Department of Health and the Minnesota Pollution Control Agency before moving to the federal government with USGS in 2009. My favorite research topic is occurrence, geochemistry, and mobilization of arsenic in natural groundwater systems. Developing models for the behavior of arsenic in the natural environment is elusive due to its complex associations with other metals and minerals, and the interplay of redox, pH, biogeochemistry, and hydrogeology. Even after 25 years of arsenic research, I continue to be fascinated.
