Simple characterization methods available to small volume of samples were applied to groundwater and surface water in the Horonobe area, Hokkaido, to characterize dissolved organic matter (DOM) including humic substances. The results indicate that the methods applied in this study are useful for the characterization of DOM in groundwater using a small sample volume.
