Data on concentrations of dissolved PAHs and dissolved organic carbon (DOC) in 20 water samples collected from the River Wyre at five sites between Marshaw Wyre, one of the two headwaters of the River Wyre, and Garstang from August 2010 to June 2011. As typical for this region, the upland reaches of this river drain peatland areas, resulting in a relatively high dissolved organic carbon content. PAHs were measured as freely dissolved PAHs (i.e. freely dissolved in the water phase) and total dissolved PAHs (the sum of freely dissolved and those associated with DOC) and the fractions associated with DOC have been estimated from these two. Where possible, the DOC-water partition coefficient of the PAHs, calculated from the concentrations determined, is given as well. The data is presented as one table and two supporting files containing metadata. Full details about this dataset can be found at https://doi.org/10.5285/24200DBA-D0F4-4BE4-AE6F-2C6EC1147FA4
