Use of Steam Chemistry for Monitoring Acidic Deposition Effects in the Adirondack Region of New York
Gregory B. Lawrence, Bahram Momen, and Karen M. Roy

Abstract (abbreviated)
Sampling Bald Mountain BrookAcid neutralizing capacity (ANC) and pH were analyzed on a weekly basis from water samples taken from three streams in the southwest Adirondacks. These data were used to test whether trends in stream chemistry might be related to changes in acidic deposition.

Analysis reveals ANC and pH increased in all three streams from 1991 through 2001. However, both were highly correlated with flow. With flow variation removed, each stream exhibited unique ANC and pH patterns. Unadjusted ANC measurements at Buck Creek, an acidified system, showed an improvement of 1.5 µeq/yr. After adjustment for flow however, no trend is evident in ANC for the decade.
