Agricultural Antibiotics and Feed Additives as Tracers of Agricultural Impacts on Surface Water

Water quality parameters such as bacterial and nutrient pollution can be impacted by a variety of sources or a combination thereof, including human wastewater, stormwater, and runoff from agricultural activities such as livestock farming. Currently, the Miller-Schulze laboratory is developing analytical methodology to quantify chemical tracers of livestock activities, such as agricultural antibiotics and feed additives, in surface and ground water.  These livestock tracers could be utilized in conjunction with our existing suite of tracers of human wastewater to provide valuable source identification information and direct correction activities.  This project is in collaboration with staff at the Center for Urban Waters at the University of Washington, Tacoma.
