Top: The Newport River (pictured here) was the tidal freshwater system studied in this research. Bottom: Concentrations of reactive nitrogen were measured upstream and downstream of a wastewater treatment facility. Precipitation and tidal influence affected nitrogen pollution patterns in an estuarine tidal creek. Images by Anne Margaret Smiley.
