Short summary

The effect of soluble reduced iron, Fe(II), on fluorescence data (excitation–emission matrix spectra parsed using parallel factor analysis) is difficult to quantitatively assign. We added varying quantities of Fe(II) into groundwater from an anaerobic aquifer. We showed that the overall fluorescence intensity decreased nonlinearly as Fe(II) increased from 1 to 306 mg L^-1 but that the parallel factor analysis component distribution was relatively insensitive to Fe(II) concentration.
