Aquifer-scale Observations of Iron Redox Transformations in Arsenic-Impacted Environments to Predict Future Contamination: Data

Compilation of groundwater geochemistry data from compiled references and sediment classification from Nghiem et al. 2020 across South and Southeast Asia. The folder contains a Readme.txt file that describes the data and the data sources. This data was compiled as part of the Characterizing Global Variability in Groundwater Arsenic Working Group supported by the John Wesley Powell Center for Analysis and Synthesis, funded by the U.S. Geological Survey. Supplementary data to Nghiem et al. 2020, “Aquifer-scale Observations of Iron Redox Transformations in Arsenic-Impacted Environments to Predict Future Contamination”, Environmental Science & Technology Letters, DOI: 10.1021/acs.estlett.0c00672
