DescriptionRather than interpret the late-time behavior of rhodamine WT (RWT) breakthrough curves in stream tracer studies as indications of hyporheic exchanges we suggest that RWT is lost by sorption. We assessed the transport of RWT compared with NaCl during and after a 5 hour co-injection steady state drip experiment conducted in a headwater mountain stream. We hypothesize that RWT is not transported conservatively compared to the NaCl tracer. Furthermore, we hypothesize that this relationship between RWT and NaCl transport can be seen both along the stream reach scale and across the sediment water interface.
