Twelve streams draining the Green Mountains in Vermont were sampled five times along elevation gradients for pH, alkalinity, and conductance to assess their acidification status. Streamflow and precipitation pH were continuously monitored at one site to characterize rainfall/runoff pH depressions. Streamflow pH, alkalinity, and conductance varied both temporally and spatially. Lower streamflow pH, alkalinity and conductance values occurred during spring runoff and at higher elevations. Streamflow chemistry was related to certain acidic deposition sensitivity criteria, including: elevation, watershed area, surficial geology, and bedrock geology. Episodic drops in streamflow pH were primarily described by peak discharge.
