Coastal Groundwater Quality Evaluation and Hydrogeochemical Characterization Using Chemometric Techniques

The physicochemical parameters and heavy metals concentration in the groundwater of coastal region Lasbela, Baluchistan were investigated. Cations anions determined through ion chromatography. levels eight (Cr, Cd, Pb, Zn, Fe, Cu, Mn) analyzed analytical procedures atomic absorption spectrophotometry. cations present descending order magnesium > sodium calcium potassium as bicarbonate sulfate chloride. Two (bicarbonate total dissolved solids) above other indices below threshold limits WHO. Positive correlations pH electrical conductivity observed with anions. significant positive correlation between (0.427) indicated dissolution carbonate rocks. (Cu, Mn, Cr, Ni) ranged from 0.1 to 0.4, 0.02 0.09, 0.04 0.9, 0.03 0.5, 0.01 0.91, 0.05 1.30, 0.60, 0.90 mg/L. highest Pb (0.21 mg/L) Cd (0.16 approximately 20 50 times higher than permissible Hierarchical cluster analysis classified twelve into four clusters seven clusters. Principal component extracted latent components for properties eigenvalues greater 1.0 that had loads fluoride, iron, conductivity, sodium, cadmium, sulfate. Major pollutants accounted by PC 1, main factors affected water quality Cu. Fe a modest impact on this region. From findings, it can be concluded has metals, which makes unfit drinking purposes.
