Methodology Summary: Hydro-Geochemical Analysis of Water Resources Data Collection: Hydro-Geochemical Parameters: Physicochemical characteristics of water from 14 rivers, 20 artisanal wells, and 15 springs were collected during both dry and rainy seasons. Parameters Measured: Measurements included temperature, dissolved oxygen, pH, electrical conductivity, cations (Na, K, Ca, Mg, total Fe), and anions (HCO3, Cl, SO4^2-, CO3^2-). Objective: Characterization of Water Composition: The analysis aimed to characterize the chemical makeup of water in various environments, providing crucial information for community consumption and water resource utilization. Sampling Approach: Seasonal Sampling: Sampling periods were conducted during defined campaigns corresponding to rainy and dry seasons. Measurement Method: Physicochemical parameter measurements were performed in situ, while samples for anions and cations underwent collection from wells, springs, and surface water at different study area points. Chain of custody protocols were followed for sample transfer to the laboratory. Data Analysis: Analytical Tools: The Piper triangular diagram was employed for data analysis, using the specialized Aqua Chem program designed for groundwater analysis. Visualization: Iso-concentration maps were generated to visualize the most significant analyses at various sampling points. This methodology summary describes the approach taken to collect hydro-geochemical data from different water sources during distinct seasons, the parameters measured, the sampling methodology, and the analytical tools used to characterize and analyze the chemical composition of water resources for community benefit and informed water resource management.
