Abstract
Aim: To assess contamination of borehole water by heavy metals (Fe, Zn, Pb, Cr, Cu, Ni, Mn). Study Design: Water samples collected from fifty two boreholes in twelve Local Government Areas (L.G.A) of Nasarawa State were analyzed forthe heavy metal concentrations. Place and Duration of Study:Samples were collected from Akwanga, Awe, Doma, Garaku, Karu, Keana,Keffi, Lafia, Nasarawa, Nasaraw a Eggon, Toto, and Wamba,during the dry season. Methodology: The water samples were prepared according to standard methods. Heavy metal levels in the samples were quantitatively determined using atomic absorption spectrometry (AAS). Results:The highest concentrations of Zn (1.81± 1.19 mg/l) and Fe (0.89± 1.73 mg/l) were recorded at Keana, while their lowest levels were observe d at Lafia. Pb ranged from Original ResearchArticle
