    ASSESSMENT OF GROUND-WATER AND STREAM QUALITY FOR TRACE METALS AND PHYSICO-CHEMICAL CONTAMINATIONS IN TOTO LOCAL GOVERNMENT AREA OF NASARAWA STATE, NIGERIA
    (FACULTY OF NATURAL AND APPLIED SCIENCE NASARAWA STATE UNIVERSITY, KEFFI., 2008-08-02) Aremu, M. O.; Sangari, D. U.; Musa, B. Z.; Chaanda, M. S.
    Water samples collected from nine sampling points of three different sources (Well, Bore-hole and Stream) within Toto Local Government Area of Nasarawa State, Nigeria were analysed for trace metals and physico-chemical properties. The trace metals Na, K, Cu, Mg, Fe, Ca, Zn, Pb, Cd, As, Se, Cr and Hg were analysed using atomic absorption spectrophotometric method. Alkalinity, pH, temperature, turbidity, conductivity, total solids, total dissolved solids, suspended solids and soluble anions such as phosphate, chloride, nitrate and bicarbonate were the physico-chemical parameters analysed using standard techniques. The results showed that Cd and Hg were not at detectable range for all the water samples. High spatial variations in the concentrations of the metals and physico-chemical parameters determined were recorded. The trace heavy metals were below the deleterious level while the physico-chemical properties of the water were within the required standard limits set by World Health Organisation (WHO) for drinking water except phosphate ion. However source protection is proposed for these waters for the benefit of mankind

    GEOCHEMICAL ANALYSIS OF WATER QUALITY IN THE TILDEN FULANI AREA OF BAUCHI STATE, NIGERIA
    (Chemistry Department, Nasarawa State University, Keffi, 2008-01-01) Chaanda, M. S.; Moumouni, A.; Golki, N. G.; Aremu, M.O.; Binbol, N. L.
    The relationship between water quality and mining activities in the Tilden Fulani area oj Bauchi State. Xigeria was investigated. Primaty data on water samples were abstracted from 56 points made up of old mines, ponds, rivers, streams and hand-dug wells. Samples were analyzed for iron (Fe), copper (Cu), lead (Pb), zinc (ZnJ and cadmium (Cd) using the Atomic Absorption Spectro-pliotometer (AAS). The results obtained showed that Cu andZn were within limits oj general acceptability by the World Health Organization (WHO) standard. Fe, Cdand Pb werefound to have had high concentrations above acceptable limits in some wells (Fe 0.05-1.10 ppm; Cd 0.005-0.01ppm and Pb 0.05-1.10 ppm). The implications of the findings were discussed with respect to the geology* ofthe study area. The higher values oftoxic metals were attributed to mining and anthropogenic activities in the studied area. The research concludes that stringent measures should be taken to properly treat the water in Tilden Fulani for domestic consumption
