Research on the effects of acidic deposition in the United States has focused largely on the role of sulfur deposition in the acidification of surface waters. Results from both long-term (up to 70 years) and recent monitoring of stream chemistry in the Catskill Mountains of New York indicate, however, that nitric acid has a significant and increasing role in surface water acidification that, during high-flow periods, rivals the role of sulfuric acid. Nitrate increases with increased stream flow throughout the year except during the late summer, when biological activity and its attendant nitrogen uptake are greatest; peak concentrations as high as 128 micrograms/l have been recorded during spring snowmelt. In contrast, sulfate concentrations decrease with increased flow.
