Combined wetfall and dryfall were collected from June, 1985 to September, 1986 in the northeast quadrant of metropolitan Atlanta on the campus of Mercer University Atlanta, Polyethylene carbouys and a standard rain gauge were used as collection devices. Sixty events were noted. Anion concentration and pH were monitored. Anions were determined with a Dionex 2020i ion chromatograph. Anions found were SO/sub 4//sup 2 -/, NO/sub 3//sup -/, and Cl/sup -/. Sulfate concentrations ranged from 34.6 to 348 ..mu.. eg L/sup -1/ with a mean concentration of 124..mu.. eq L/sup -1/. Nitrate ranged from 0 to 137..mu.. eq L/sup -1/ with a mean of 40.1..mu.. eq L/sup -/, and chloride from 13.6 to 207..mu.. eq L/sup -1/ with a mean of 40.0..mu.. eq L/sup -1/. The pH ranged from 3.6 to 7.0 with a mean of 4.8. Plots of (H/sup +/) versus total anions, anion combinations such as (NO/sub 3//sup -/) + (SO/sub 4//sup 2 -/), and individual anions all showed scatter patterns with slight positive trends observed for (H/sup +/) versus (NO/sub 3//sup -/) and (SO/sub 4//sup 2 -/). Acidic cations such as (NH/sub 4//sup +/) may also be contributing to total pH.
