Abstract

The effects of acid deposition on surface waters in eastern USA watersheds of similar size, physiography, climate and land-use are related to the composition of the underlying bedrock. Watersheds developed on greenstone, calcareous shale, sandstone, granite and schist differ in their ability to neutralize acid rain; consequently, stream acidity is similar to that of precipitation. Watersheds developed on granite and schist are intermediate in their capacity to neutralize acid deposition. Bedrock composition appears to be the major property controlling surface-water chemistry in these systems; hydrological flowpaths and the nature of surficial materials and vegetation also influence chemical responses to acid deposition in watersheds. 453This and the following 10 abstracts are for papers forming a thematic set on geochemical aspects of acid rain. -P.Br.
