| Abstract: | A 20-year record of water chemistry for seven headwater streams in the Rocky Mountain region of the western United States is compared to estimates of local and regional sulfur dioxide emissions. Emissions from smelters comprise a significant part of sulfur dioxide emissions for the 11 states upwind of acid-sensitive watersheds in the Rocky Mountains, but smelter emissions have steadily decreased since 1970. Analysis of stream chemistry indicates conservative behavior of watershed sulfate, with atmospheric deposition as the dominant source. No relation between regional stream chemistry and smelter or regional sulfur dioxide emissions is detected. Local emissions trends, however, do appear to affect sulfate concentrations in the streams. -from Authors |
