Streamwater pH, Sulfate, Copper, and Zinc Concentration Data Collected from 1980 to 2021 in Mineralized Watersheds Throughout the Colorado Rocky Mountains, USA

This database was collated from publicly available sources to support the study presented in Manning et al. (in press). The purpose of the study was to evaluate temporal trends in the chemistry of headwater streams in Colorado, USA, draining mineralized (hydrothermally altered) areas affected by acid-rock drainage. The database contains pH and sulfate, zinc, and copper concentration data for streamwater samples collected from 1980 to 2021 during late summer and fall (July 15 through November 30) at 22 different sites. Additional details regarding data aggregation provided in Manning et al. (in press).
