Short summary
Storm-enhanced export of particulate organic carbon in a mountainous headwater stream increased nonlinearly above thresholds of precipitation and discharge, far exceeding the relatively small increases of dissolved organic carbon. Particulate organic carbon exported during extreme storm events provide potential sources of reactive organic components that can rapidly biodegrade and form disinfection byproducts such as trihalomethanes in the headwater stream.
