Hydrochemistry_ACWs

This dataset contains hydrochemical data collected during 18 sampling campaigns between June 2023 and January 2024 at the Inlet and the effluents of three anaerobic constructed wetlands (CW01, CW02, CW03) of the Bioremediation Pilot Plant, in the Negro River sub-basin, Cordillera Blanca, Peru. The ACWs treat river water contaminated by acid rock drainage associated with glacial retreat. Variables include pH, temperature, electrical conductivity, total dissolved solids, oxidation-reduction potential, sulfate, and metals and metalloids. Numeric values shown in blue font are below the limit of quantification (LOQ).
