Stream hydrochemistry reflects coupled hydrological, biological, and geological processes within the critical zone. Here, we explore linkages between inputs (e.g., via atmospheric deposition), storage, and outputs (e.g., of water quality via streamflow export), of elements within forested catchments in the mid-Appalachian region of Pennsylvania. Long-term time series data of atmospheric deposition and stream chemistry allow us to explore how seasonality and lag times affect water quality. Results suggest the importance of hydrological transport, geochemical weathering, biogeochemical processing in the transport and transformation of elements in the critical zone.
