Geochemical Data of Groundwater in Kribi (South Cameroon): Indicators of Marine Intrusion and Water Quality
Description
This dataset contains the physico-chemical and chemical parameters of groundwater samples collected from Kribi, South Cameroon, aimed at assessing water quality and salinity levels. The dataset includes two Excel files: Database_Geochemical Data (physical parameters) and Database_Chemical Parameters (chemical analyses). The first file comprises 60 data points distributed across three tables: Table 1 – River and Spring, Table 2 – Domestic Wells, and Table 3 – Public Boreholes. Measured parameters include Temperature (°C), pH, Electrical Conductivity (µS/cm), Total Dissolved Solids (mg/L), Salinity (%), Elevation (m), Geographic Coordinates (Easting, Northing), and Source Type. Among these 60 samples, 26 were selected for laboratory chemical analysis based on salinity levels, forming the second file (Database_Chemical Parameters), which contains chemical analyses from Public Boreholes, including cations (Na⁺, K⁺, NH₄⁺, Ca²⁺, Mg²⁺), anions (F⁻, Cl⁻, NO₃⁻, SO₄²⁻), and hydrochemical indices (SAR, MAR, KR). Physical parameters were measured in the field using portable probes and GPS, while chemical parameters were analyzed in the laboratory by MP-AES for cations and Ion Chromatography (IC) for anions. Hydrochemical indices were calculated using standard formulas. This dataset provides essential baseline information for evaluating groundwater quality, potential salinization, and suitability for domestic or agricultural use. It is intended for hydrogeological research, water resource management planning, and environmental monitoring.
