This paper summarizes the alteration of water chemistry during its passage through different ecosystem compartments for three forest types in the Southern Appalachians. There is a significant depletion of hydrogen ions in pine and oak-hickory forests as water passes through successive canopy, forest floor, and soil compartments. The net change in H7 concentrations between precipitation and stream water is equivalent to about 2 pH units; i.e., pH increases from 4.5 to 6.5. Patterns of base cation changes through compartments are generally similar for the two pine and the hardwood forest types, but with a few exceptions. Patterns between forests appear to be most different for NO3 and SO4, which are mediated by microbial transformations.
