A major uncertainty in hydrologic and chemical modeling of watersheds has been the quantification of the contributions of water and solutes from various hydrologic pathways. Hydrologic models exist that can reproduce the timing and quantity of the hydrograph, but when chemical data are coupled with these physical models, they do not accurately reflect the streamwater chemistry. Therefore, it has been concluded that either the hydrologic pathways are represented inaccurately in the models or the processes affecting the water chemistry are not well understood.
