    EVALUATION OF GROUNDWATER QUALITY FROM SHALLOWHAND-DUG WELLS FOR DOMESTIC AND IRRIGATION USES IN TUDUNWADAAND ENVIRONS, PARTS OF ALKALERI SHEET 150 AND YULI SHEET 171, NORTHEASTERN NIGERIA
    (Department of Geology and Minning, Nasarawa State University Keffi, 2020-01-11) Kana, M.A.; Ancho, I.M.; Usman, Halima Osu
    The study centres on the hydrochemistry of groundwater from shallow hand-dug wells in Tudun Wada and environs intending to evaluate its quality for domestic and irrigation uses. The area is underlain by both basement and sedimentary rocks. The basement rocks in the area include porphyritic biotite granite and granitic gneiss while sedimentary rocks includes and stone, claystone and shale. Ten (10) pairs of water samples (totalling twenty (20) samples –that is, two samples were collected from a point) were randomly collected from hand dugwells in the study area and analyzed for major cations and anions. The dominant cations and anions were in the order of Mg > Ca > Na > K and HCO3> Cl > NO3>SO4respectively. Results of the water quality analysis were compared with the standards set by the World Health Organization and the Nigerian Standard for Drinking Water Quality. Geochemical values of the water samples analyzed showed that groundwater from hand-dug wells in the area are suitable for domestic uses. Groundwater quality from hand-dug wells in the area was also analyzed for its suitability or otherwise, for irrigation using Sodium Absorption Ratio, Residual Sodium Carbonate, Kelley Index, Magnesium Ratio, Percentage Sodium, Permeability Index, Total Hardness, Total Dissolved Solids, and Electrical Conductivity parameters respectively. The result revealed that groundwater from hand-dug wells in the area is good for irrigation according to Sodium Absorption Ratio, Residual Sodium Carbonate, Total Dissolved Solids, Percentage Sodium, Kelley Index, and Permeability Index; poor according to Magnesium Ratio, and partly good according to Electrical Conductivity. The sources of dissolved chemical constituents of groundwater in Tudun Wada and its environs are rocks (sandstone, claystone, shale, porphyritic biotite granite, and granitic gneiss). This is because all the sample points’ fall within the region of rock dominance based on Gibbs’ plot.

    Evaluation ol Groundwater Quality From Shallow Hand-Dug Wells for Domestic and Irrigation uses in Tudun Wada and environs, Parts of Alkaleri Sheet 150 and Yuli Sheet 171, Northeastern Nigeria

    1 he study centres on the hydrochemislry of groundwater from shallow hand-dug wells in Tudun Wada and environs intending to evaluate its quality for domestic and irrigation uses. The area is underlain by both basement and sedimentary rocks. The basement rocks in the area include porphyritic biotile granite and granitic gneiss while sedimentary rocks include sandstone, claystone and shale. Ten (10) pairs of water samples (totalling twenty (20) samples - that is. two samples were collected from a point) were randomly collected from hand dug-wells in the study area and analysed for major cations and anions. The dominant cations and anions were in the order of Mg > Ca > Na > K and I-ICO3 > Cl > NO;, > SO-i respectively. Results of the water quality analysis were compared with the standards set by the World Health Organization and the Nigerian Standard for Drinking Water Quality. Geochemical values of the water samples analysed showed that groundwater from hand-dug wells in the area are suitable for domestic uses. Groundwater quality from hand-dug wells in the area was also analysed for its suitability or otherwise, tor irrigation using Sodium Absorption Ratio. Residual Sodium Carbonate, Kelley Index. Magnesium Ratio. Percentage Sodium. Permeability Index, Total Hardness. Total Dissolved Solids, and Electrical Conductivity parameters respectively. The result revealed that groundwater from hand-dug wells in the area is good for irrigation according to Sodium Absorption Ratio. Residual Sodium Carbonate, Total Dissolved Solids. Percentage Sodium. Kelley Index, and Permeability Index; poor according to Maunesium Ratio, and partly good according to Electrical Conductivity. The sources of dissolved chemical constituents of groundwater in Tudun Wada and its environs are rocks (sandstone, claystone. shale, porphyritic biotile granite, and granitic gneiss). This is because all the sample points' fall within the region of rock dominance based on Gibbs' plot.

    Hydro-Geophysical Assessment of Groundwater Potential and Aquifer Vulnerability of the Turonian Makurdi Formation in North Bank area, Makurdi, Middle Benue Trough, Nigeria
    (Department of Geology and Minning, Nasarawa State University Keffi, 2022-01-01) Obrike, Stephen E.; Baba, Adama Oleka; Ojuola, B.S.; Anudu, G.K.; Kana, M.A.; Iliya, M.M.
    Electrical resistivity investigation was carried out in North Bank and its environs in Makurdi, Benue State, with a view to determining the depth to aquifer, aquifer thickmess, groundwater potential of the area and aquifer vulnerability. Twenty-one (21) Vertical electrical sounding (VES) was carried out using the Schlumberger electrode array with the aid of ABEM Terrameter (SAS 3000C) with maximum electrode spacing of 200m. The VES data obtained were interpreted using partial curve matching approach and modelled using WinResist software. Modelled field curves reveal essentially three to four geo-elcetrical layers and two main aquiferous zones corresponding to the upper silty-sandstone and lower medium to coarse grained felspathic sandstones of the Makurdi Formation. The upper silty-sandstone aquifer is characterized by low to moderate resistivity value distribution (37 - 2039 ohm-m) with layer thickness in the range of 3m to 15m. Computed hydraulic and geo-electric characteristics (Zarrouk parameters, hydraulic conductivity and transmissivity) depicts it as unconfined, vulnerable to infiltrating surface 2 -1 2 -1 contaminants, with low groundwater potential (0.63 m day < T 199.65 m day ) and only suitable for small community water supply projects and private consumption. The lower felspathic sandstone aquifer is characterized by relatively thicker sequence of aquiferous materials (3m – 54m). The aquiferous zone is generally unconfined to 2 -1 2 -1 semi-confined in nature, with groundwater potential (30.96 m day < T ≤ 542.73 m day ) seen to be largely moderate. The aquifer is deemed suitable for industrial, irrigational and municipal water supply purposes

    HYDROCHEMICAL ASSESSMENT OF SURFACE AND GROUNDWATER QUALITY IN SISIN BAKI, FARIN RUWA AND ENVIRONS, PART OF KURRA SHEET 189 SW, NORTH CENTRAL NIGERIA
    (Department of Geology and Mining, Nasarawa State University Keffi, 2020-01-01) Ma'aji, U.M.; Kana, M.A.; Iliya, M.M.
    The study area, Sisin Baki, Farin Ruwa and environs are located in Wamba Local Government Area of Nasarawa State in Kurra sheet 189 SW, North Central Nigeria. It is bounded by Latitudes 090 00’ 00” N to 090 07’ 30” N and Longitudes 080 35’ 00” E to 080 45’ 00” E, covering an area of about 253 km2. It is underlain by the Basement Complex rocks of north-central Nigeria generally undulating with many reliefs which are influenced by the geology. The topography is characterized by many high mountains and some low lands drained by rivers and streams which are used for agriculture. Twenty-seven (27) samples of both surface water (streams and rivers) and groundwater (boreholes and shallow wells) were collected from the study area following the standard procedure as prescribed by APHA (1995) guidelines. Various physical parameters (T0C, pH, TDS, EC, TH) and chemical parameters such as major anions (Cl−, SO4 2−, CO3 2−, HCO3 2−), and cations (Na+, K+, Ca2+,Mg2+) were analysed using standard procedures. The dominant ions were in the order of Mg > Ca > HCO3 > Na > Cl > K > SO4. The results showed that the groundwater in the area is predominantly suitable for drinking. The assessments of water studied for irrigation show that almost all the water sources of the study area are suitable for irrigation purposes
