Summary

As part of the Episodic Response Project (ERP), we intensively monitored discharge and stream chemistry of 13 streams located in the Northern Appalachian region of Pennsylvania and in the Catskill and Adirondack Mountains of New York from fall 1988 to spring 1990. The ERP clearly documented the occurrence of acidic episodes with minimum episodic pH ??? 5 and inorganic monomeric Al (Alim) concentrations >150 ??g/L in at least two study streams in each region. Several streams consistently experienced episodes with maximum Alim concentrations >350 ??g/L. Acid neutralizing capacity (ANC) depressions resulted from complex interactions of multiple ions. Base cation decreases often made the most important contributions to ANC depressions [...]
