The goal of Dr. Soupir’s research program is to conduct basic research towards the development of sustainable water systems. Her broad research interests include nonpoint source pollution control, watershed management, and water quality monitoring. She uses both lab and field scale studies to examine the occurrence, fate and transport of pathogens, pathogen indicators and contaminants of emerging environmental concern (CoEECs) such as antibiotics and antibioticresistant bacteria to surface and groundwater systems. Findings from these studies have implications to improve the Total Maximum Daily Load (TMDL) development and implementation process, identify the impact of land use practices on water quality, and develop management practices to reduce pollutant transport. Her previous projects include examining the fate and transport of nutrients and pathogen indicators from pasturelands receiving animal waste applications and comparing erosion from construction areas treated with polyacrylamide to those treated with traditional erosion control practices. Her research program is currently funded by the Iowa Department of Natural Resources, the National Pork Board, the National Science Foundation, the Iowa Egg Council, and the U.S. Environmental Protection Agency.
