Groundwater naturally enriched with inorganic arsenic species. Classification of groundwater sources using Fuzzy Hierarchical Cross-Clustering. PO43−–AsO43− ion exchange and water-rocks interactions as sources of As. Na+–F−–pH cluster as marker for As naturally enriched groundwater. Co-occurrence of As species and F− under the influence of HCO3− and alkaline pH.
