Under baseflow conditions, wastewater treatment plants and urban areas dominated the chemical profile and toxicity potential of the pollutant mixture in the Ammer River despite substantial agricultural activity in the catchment. Under storm and rain conditions, a much higher burden of pollutants and toxicity is carried in the river water compared to baseflow. The overall objective of project P1 is to elucidate major sources, the fate, and toxicity patterns of chemical mixtures during high discharge events. We (1) execute year-round field campaigns to sample agricultural and urban runoff components at pre-selected locations in the Ammer catchment during storm events of different intensities and duration, (2) consider particle-associated pollutants, both in suspended solids and bed sediments, and (3) investigate attenuation processes and mixture toxicity of organic contaminants and their transformation products in a controlled injection-extraction experiment along an aquifer trajectory.
