Abstract: | To understand the nature of sediment-associated nutrient and contaminant transport dynamics in fluvial systems, a stormflow
sampling program of suspended solids is reported for one water year in a representative rural diffuse source catchment of
southeastern Ontario. Bulk samples of subsieve suspended solids were obtained using field-portable continuous-flow centrifuge
apparatus. The physical and geochemical properties of suspended solids show no significant intersite differences over reaches
of 1 500–2 000 m, yet display distinctive seasonal trends. Systematic seasonal changes in particle size, organic content,
and Ca, P, Mn, Al, Ti, Fe, and K appear to reflect the changing role of partial area hydrology. Ca, P, and Mn are bioaccumulated
by stream algae. Mineral signature is relatively constant over the year.
