Springs - Physicochemical - Lake Turkana Basin (ETH)
This dataset compiles comprehensive hydrogeological and hydrochemical measurements from a network of spring sampling sites. For each sample, precise spatial coordinates and elevation are recorded alongside metadata on sampling methodology, provenance, and project affiliation. In‐field parameters—including temperature, pH, electrical conductivity, total dissolved solids, and turbidity—are complemented by laboratory analyses of major cations (Na⁺, K⁺, Ca²⁺, Mg²⁺), anions (Cl⁻, HCO₃⁻, SO₄²⁻, NO₃⁻, F⁻, etc.), trace metals (Fe, Mn), and indices of organic content (TOC, BOD₅, COD). Accompanying each record are data source attributions (e.g., unpublished theses, government reports, peer‐reviewed articles) and acquisition dates. This integrated dataset supports groundwater quality assessment, aquifer characterization, and sustainable resource management across the study region.
