    Baseline Concentration of Morbid Leachate In Well Water In Ankpa, Kogi State, Nigeria.
    (Department of Geography, Nasarawa State University Keffi, 2014-11-01) Nasiru, Idris Medugu; Abiola, K.A.; Ekanada, O.; Opaluwa, O.D.; Omale, L.; Mohammed, A.B.
    Water is abundant natural resources which is critical for the sustenance of human life. It is a well-known fact that adequate supply of fresh and clean drinking water is a basic need for all human beings on the earth. This research aimed to determine the trace of metals and other physico-chemical properties in water samples collected from eight selected location in the study area (Enjema-Ofugo) in Ankpa Local Government Area of Kogi State. The investigated metals (Na, K, Pb, Cd, Se, and Cr) were analysed using atomic absorption spectrophotometric method while Alkalinity, pH, temperature, turbidity, conductivity, total solids, total dissolved solids, suspended solids and soluble anions (phosphate, chloride, nitrate, and bicarbonate) and other physico-chemical parameters were analysed using appropriate standard techniques. The results also showed that Cd, Se and Hg were not detected, while other physico-chemical parameters were within the permissible limits set by World Health Organization (WHO) for drinking water except phosphate ion. However, source protection is recommended for the water bodies for the benefit of the community people in the study area.

    SALINE WATER VARIABILITY IN AZARA DEVLOPMENT AREA OF NASARWA STATE
    (Department of Geography, Nasarawa State University Keffi, 2016-10-02) Nasiru, Idris Medugu; Abiola, K.A.; Ogah, T.A.; Opaluwa, O.D.
    This study examines the variability of saline water properties under salt mining activities in Ribi, Azara and Akiri areas of Azara Development Area. A total number of Forty (40) water samples were collected and analysed for the physical, chemical and environmental impact of saline water in the three areas. The results of the chemical analysis revealed that the cation concentration are in order of Na, >Ca2+>Mg2+ while that of anions are in the order Cl->HCO3->SO22+>SO42-. In percentage, the degree of metal concentration is comparable in the two study areas, except for some non-metals. Significant positive correlations were observed between and among the variables in the three areas. The geo-accumulation index order for brine are in these order Na >Ca> Mg>Mn> Al > Cr > Li. The major salts identified were Cl-, HCO32-, SO42-, and NO32-. The high electrical conductivity value recorded is as a result of high concentration of brine water in the study areas.

    VARIABILITY OF BRINE WATER QUALITY IN KEANA AND AWE, NASARAWA STATE, NIGERIA
    (Department of Geography, Nasarawa State University Keffi, 2014-11-22) Nasiru, Idris Medugu; Ayuba, H.K.; Abiola, K.A.; Funmilola, A.
    This study examines the seasonal variability of water properties under mining activities in Awe and Keana Local Government Areas of Nasarawa State.. A total number of eighty (80) water samples were collected and analysed for the physical and chemical and environmental impact of brine water in the two areas. The results of the chemical analysis revealed that the cation concentration are in order of Ca2+ < Mg2 > Na, while that of anions are in the order HCO3 > SO2 2+ > SO42+ > Cl. The concentrations of heavy metal (Cd,Cu, Nm, N, Pb, Zn, Al, Cr, and Fe) were determined in salt water using Aua Regia Extraction analysis. The concentration of heavy metal in the soil samples ranges as follows (ppm): Cd (0.001 trace), Cu (0.01 – 8), Nm (12 – 60), Ni (Trace), Pb (0.01 – 8), Zn (0.001– 6), Al (0.65 – 2.50), Cr (Trace), Fe (0.02 > 10). In percentage, the degree of metal concentration is comparable in the two study areas, except for some non metals. Significant positive correlations were observed between and among the metals. The geo accumulation index order for brine in Fe > Cu > Zn > Mn > Al > Pb > Al > Cd > Ni > Sn. Evaluation of chemical analysis results revealed that there are significant variations between metals. The major salts identified were HCO32- , SO42-, Cl -, and NO32-., The high conductivity value recorded in the HCO3- is as a result of high concentration of brine water in the study areas.
