Amy Edwards Simonson is a hydrologist with the New York Water Science Center.
Amy has measured groundwater and streamflow throughout Long Island and New York City. With a background in geochemistry, she's also assisted in several water-quality projects with the USGS. After major hurricanes and flood events, Amy is heavily involved in documenting peak water levels, flows, and other impacts. She is currently part of NYWSC's Observing Systems Operations Branch.
