Optical and photochemical parameters of the samples were measured under controlled laboratory conditions. The data were collected to identify environmental variables that constrain the yield of triplet excited states of dissolved natural organic matter. Apparent quantum yields of these triplet states were measured using the chemical probe, 2,4,6-trimethylphenol, under a broadband xenon-arc lamp with a 290-nm wavelength filter.Attribution-NonCommercial 4.0 Internationalhttp://creativecommons.org/licenses/by-nc/4.0/environmental photochemistrytriplet excited states of dissolved organic matterdissolved organic matter2,4,6-trimethylphenolwetlandswatershedDatasethttps://doi.org/10.13020/D68H5Z
