Description:

The role of groundwater sulfate discharge to ponds and streams within the Goose River basin (33.3 km²) is examined. While airborne sulfate disposition has declined, acidity in surface waters locally remains elevated. Monthly SO^2-₄ analyses (1999-2002) of wet deposition and surface waters are reported, and a sulfate budget for six catchments of the Goose River watershed, Maine is calculated. Groundwater δ³⁴S_SO4 values from different bedrock types are beneficial in identifying groundwater source(s) of sulfate in surface waters and discriminating them from atmospheric sulfate deposition. The variability of proposed sulfide oxidation among certain local chalcophile rocks and the depth of aeration in these sheared granitoids are elucidated from δ¹⁸O_SO4 and δ ¹⁸O_H2O data. Cosmogenic ³⁵S_SO4 residence times estimate new atmospheric SO^2-₄ deposition in the catchments and production of SO^2-₄ from water-rock interactions among some fractured granitoids.
