The suspended sediment, total zinc, dissolved zinc concentrations, as well as the flow rate for the Spring River Watershed. Meteorological data was extracted from the PRISM database. Additionally, are the output values for MINTEQ simulations that were performed for part of the dataset that included pH and alkalinity measurements of the water samples. This dataset is associated with the following publication: O'Connor, K.F., S.R. Al-Abed, P.X. Pinto, and P.M. Potter. Zinc transport and partitioning of a mine-impacted watershed: An evaluation of water and sediment quality. APPLIED GEOCHEMISTRY. Elsevier Science Ltd, New York, NY, USA, 142: 105333, (2022).
