Cover Story: Organic charge concentration, measuring dissolved natural organic matter (DNOM), may be determined through charge balance calculations (Org.−) or modelled (OAN−) using conceptual models based on the density of the weak acid functional sites (SD) present in DNOM. These models use SD as a key parameter for empirically fitting the modelled OAN− to Org.−. The charge density (CD) is governed by SD as well as protonation and complexation reactions in the functional groups. Utilizing extensive water chemistry datasets, this study shows that spatial and temporal differences in SD and CD are influenced by variations in DNOM’s humic-to-fulvic ratio, organic aluminium (Al) complexation, and the acidity-governed mole fraction of CD to SD. Over 34 years of monitoring, the CD increased by 70%, likely due to rising pH and declining Al complexation with DNOM. View this paper
