Dissolved organic carbon (DOC) and inorganic nutrients (NH4-N, NO3-N, soluble total N, PO4-P, soluble total P, and Si) were measured in ground and surface waters in the Matamek River drainage network, Quebec, Canada. In general, concentrations of carbon and nitrogen were significantly higher in groundwater than in surface water (up to 340% for DOC and up to 700% for total N). No significant difference was detected for phosphorus whereas considerable variation occurred for silicon, with significantly higher groundwater concentrations at 50% of the study sites. We hypothesize that (1) groundwater is a source of DOC and nitrogen in these systems and (2) nutrients introduced through groundwater seepage are rapidly utilized via oxidative, biotic processes within the hyporheal zone or at the sediment–water interface.
