    A priminary Assessment of Groundwater Quality of Some Shallow Wells around Kaduna Metropolis, North Central, Nigeria
    (Department of Geology and Mining, Nasarawa State University, Keffi, 2005-10-13) Jatau, B.S.; Ajodo, R. O.
    This paper presents the results of chemical analyses of groundwater samples obtained from twelve hand-dug wells located in parts of Kaduna town and environs in the Basement Complex of Nigeria. The results are evaluated with a view to determining the quality in terms of the chemistry of the groundwater within this area. The Ca2\ Mg2+, NO?', SO,2- and Cl" concentration level of 0.2 -32.1 mg/I, 0.4 - 2.6 mg/1, 2.0 - 9. 0 mg/1, 3.0 - 12.0 mg/1, and 9.0 - 60. 0 mg/I respectively for water samples are lower than the World Health Organization (WHO 2004) recommended highest desirable level of 75, 59, 45,200, and 200 mg/I respectively. No trace of iron and zinc was found in the area. The total hardness concentration level of 0.19 - 4.88 mg/1 are lower than World Health Organization WHO (2004) recommended highest desirable levels of 100 mg/I. 'flic pi 1 values (3.9 - 5.7 units) falls below the maximum permissible levels of 6.5 - 9.2 units. The piper trilincar diagram shows that the chemical properties of all the sample are dominated by alkaline earths elements. The water is slightly acidic with high percentage of hydrocarbonate ion and low percentage of sulphate and chloride ion. It is concluded that the acidity of the groundwater could be due to pollution from the industry and hence remedial solution suggested.

    RECONNAISSANCE HYDROGEOPHYSICAL INVESTIGATION , OF PART OF KADUNA TOWN AND ENVIRONS, KADUNA STATE, NIGERIA
    (Department of Geology and Mining, Nasarawa State University, Keffi, 2005-02-23) Jatau, B.S.; Ajodo, R. O.
    Thirteen vertical electrical sound points using Schlumberger array method were chosen, outside cultural interference and terrametcr SAS 300c was used to obtain the sounding curves in parts of Kaduna town and environs in the Basement complex of Nigeria. The result were interpreted using Resixp Programme (1992) to quantitatively delineate the various layers, which revealed four to six layers, with their thicknesses and apparent resistivities. The qualitative interpretations were also deduced showing the piczometric, isoresistivity, depth to basement maps and the water potential of the area. The results showed a good correlation with existing geologic and topographic and drainage maps of the study area. Its water potential of the study area varied from one place to another.
