Hydrogeochemical evolution and heavy metal characterization of groundwater from southwestern, Nigeria: An integrated assessment using spatial, indexical, irrigation, chemometric, and health risk models.

ABSTRACT: This study examines the hydrogeochemical and heavy metal parameters of groundwater in Ojo District to determine its suitability for use, potential sources, and human health implications. Ten groundwater samples were assessed, and hydrogeochemical modelling was performed via the Aquachem software. The chemical ions were in the following order: EC > (107.78-448.65 μS/cm) > TDS (182.02-320.77 mg/l) > TH (46.22-182.45 mg/l) > pH (5.55-6.35); HCO₃ ^- (64.13-125.82 mg/l) > Na⁺ (36.87-96.49 mg/l) > Ca²⁺ (47.65-58.88 mg/l) > SO₄ ^2- (19.94-53.67) > NO₃ ^- (15.55-44.25 mg/l) > Cl^- (20.43-27.16 mg/l) > Mg²⁺ (11.09-16.87 mg/l) and K⁺ (2.55-7.86 mg/l). The concentrations of heavy metal
