    Hydro-Geochemical Evaluation of Groundwater Resources From Hand-Dug Wells Around Kakuri And Its Environs, Kaduna State, Northcentral Nigeria
    (Department of Geology and Minning, Nasarawa State University Keffi, 2011-01-06) Anudu, G.K.; Obrike, Stephen E.; Onuba, L.N.; Ikpokonte, A.E.
    The paper evaluates the quality and usability of groundwater from hand-dug wells in Kakuri and its environs. A total of fifteen (15) water samples were analysed for their physical and chemical parameters. Results of the study show that 2+ 2+ + the cationic and anionic concentrations vary as follow: Ca (2.4 - 11.0 mg/l), Mg (0.5 - 2.6 mg/l), Na (0.7 - 5.4 + 2+ - - 2- mg/l), K (2.2 - 6.3 mg/l), Fe (0.03 - 0.10 mg/l), HCO (78.2 - 281.5 mg/l), Cl (8.8 - 62.2 mg/l), SO (3.9 -11.2 3 4 - mg/l) and NO3 (1.9 - 9.1 mg/l). Residual sodium carbonate (RSC), electrical conductivity (EC), sodium adsorption ratio (SAR) and exchangeable sodium ratio (ESR) values range from 0.00 to 1.680 meq/l, 62.37 to 119.43 µS/cm, 0.010 to 0.707, and 0.132 to 0.715, respectively. The study reveals that the waters are slightly acidic (5.70 =pH= 6.40), soft (9.29 = TH = 38.17 mg/l), fresh (109.6 = TDS = 192.9 mg/l), have low salinity hazard (SH) and belong to four water types, namely: Ca-Na-HCO , Ca-K-HCO , Mg-Ca-HCO , and Na-K- HCO . Statistical correlation analysis 3 3 3 3 shows that there is a strong positive correlation between most parameters. All the analysed parameters with the exception of pH were within the WHO (2006) standards for drinking water. These waters are considered to be suitable for drinking, domestic and agricultural purposes.

    Hydrochemical Analysis and Evaluation of Water Quality in Angwan Jeba and its Environs, Nasarawa state, Northcentral Nigeria
    (Department of Geology and Minning, Nasarawa State University Keffi, 2011-03-08) Anuda, G.K.; Obrike, Stephen E.; Onuba, L.N.; Ikpokonte, A.E.
    Angwan Jeba and its environs lies within the Basement Complex of northcentral Nigeria and is underlain by migmatitic gneiss, biotite gneiss, biotite schist, muscovite schist and older granites with minor intrusions of pegmatite and quartz veins. The study involved the hydrochemical characterisation of waters of the area to ascertain their chemistry, quality and suitability for domestic, livestock and irrigation purposes. A total of eight hand-dug wells, four hand-pump boreholes, one stream and two rivers water samples were analysed for their cations and anions. Physical parameters such as temperature, pH, Electrical Conductivity (EC) and Total Dissolved Solids (TDS) were measured in the field. Results of the analysed chemical (cations and anions) parameters ranged as follows: Ca2+ (9.4-36.1 mg L"1), Mg2+(3.8-11.7 mg L-1),Na+ (17.64- 41.5 mg L-1), K+ (4.36-18.14 mg L“1), Fe (0.08-3.0 mg L“1), Cu (<0.01 -0.99 mg L“1), HCO3_ (84.08-134 mg L"1), Cl(37.3-49.79 mg L "1), SO42" (13.2-23.4 mg L ') and N O ) (1 - 0 .9 6 mg The Sodium Adsorption Ratio (SAR), Residual Sodium Carbonate (RSC), Electrical Conductivity (EC) and Exchangeable Sodium Ratio (ESR) values variedbetweenO.73-l .59, -1.015-0.633meqL-1 , 159-450 pS cm ,' ando.333-1.187, respectively. Evaluation of the results revealed that the waters are fresh ( 3 0 ؛ T D S 3 0 4 mg L ') , soft to moderately hard (39.1 TH<128.85 mg L ,'), slightly acidic to slightly alkaline (6.85

    Physico - Chemical Quality of Ground Water from Shallow Wells in Galambi and Environs, Bauchi State, Northern Nigeria
    (Department of Geology and Minning, Nasarawa State University Keffi, 2007-03-03) Essien, Queen Ekenem; Anudu, G.K.; Baba, Adama Oleka; Ikpokonte, A.E.
    Physico-chemical characteristics of ground water from shallow wells in Galambi and its environ in Bauchi State, Northern Nigeria, were evaluated. A total off ifteen shallow well water samples were randomly collected and analyzed for an assessment of its potability and suitability for domestic purposes. Results obtained indicate that the ground water is slightly acidic to moderately alkaline (5.70< PH <8. JO), hard to very hard, (124.7 - 256 mg/1), colourless, and odorless. Conductivity, HCOj2', CO2', NO32', SO2', and PO4' are generally within WHO permissible levels for potable water. However, heavy metals like copper, iron, and lead are of higher concentrations than WHO standards for drinking water. Consequently, relevant treatment procedures are strongly recommended to reduce concentrations of Fe, Cu and Pb in the water so as to minimize the risks/concerns that they may pose to human health within and around the study area. The plot of the average constituents of the ground water in a Piper Trilinear diagram shows that the water is potable and can be classified as .alkaline earth water type with higher alkaline proportion (Ca- Mg -Na) and predominantly HCO3 water, as well as normal alkaline earth water type (Ca- Mg) with predominantly HCO3' water.

    Preliminary structural study of Landsat Imagery overWamba and Environs, Nasarawa state, Northcentral Nigeria
    (Department of Geology and Minning, Nasarawa State University Keffi, 2012-01-03) Anuda, G.K.; Obrike, Stephen E.; Iyakwari, Shekwoyandu; Ikpokonte, A.E.
    Wamba and environs is underlain by the migmatities, gneisses. Older Granites, Younger Granites, Awgu Shale and Lafia Formation. LANDSAT 5-TM imagery over the area has been analysed and interpreted in order to determine the lineament trends, drainage network and lineament density across the area. Rose (azimuth-frequency) diagram plots of the structures (lineaments) from both the imagery and field measurements show NE-SW, NNE-SSW, E-W, NNW-SSE andN-S directions with the dominant trends intheNE-SW andNNE- ssw directions. Two prominent faults (Fl, F2) were identified on the imagery. The superposition of the lineament map and drainage map depicts that the dendritic drainage pattern of the area is lithologically and structurally controlled. The lineament map, lineament density contour map, lineament density image map and lineament density surface map show that the lineament density is high around Monkwar, Zamatak, Ninkade, Mugu, Gwanzu and Garko underlain by migmatites, gneisses and Older Granites.

    Estimation of groundwater resources requires data on aquifer water level fluctuation and changes in water elevation with time. This work provide basis of understanding groundwater potential and solving the water scarcity of the study area. Water demand of the study area was determined. Water demand of the Teaching and Administrative area is 2,847 m3/d, for area “A” is 212 m3/d, for area “C” is 130 m3/d, for area “BZ” is 278 m3/d, for area “F” is 187 m3/d, for area “G” is 88 m3/d, for area “E” is 82 m3/d, for Catering Flats near Staff Club is 16 m3/d, for Quarters III is 90 m3/d, for Waterworks Junior Staff Quarter is 10 m3/d, for Silver Jubilee is 200 m3/d, for Aviation Site II is 60 m3/d, medical students is 93.6 m3, Shika Hospital is 154 m3/d/ respectively giving the total water demand of the study area 4,354 m3 .Since ABU Farm Lake is located about 2.5km from Bomo Lake and also that they are in the same water shed, hydrological data from Bomo Lake can be extrapolated to the Farm Lake. With 8.2 m static water level is 31.8 m saturated zone. The aquifer depth is 17,418,752 m3. Static Groundwater Resources of the study area are 18,266,708 m3. Total Dynamic Groundwater Resource are 5,166,623 m3/a. Utilizable Dynamic Groundwater Resource is 50 % of the Total Dynamic Resource. Area 42,892,705 m2. Population is 51,434. Geological map of the study area was upgraded. Map of configuration of groundwater table and its flow direction was plotted. Water budget map of the study area was produced. Volume of base flow and surface runoff calculated. Surface runoff, Surface, and Groundwater Resources of the Campus were calculated to determine its reserves and Hydrogeological map of the study area was produced.
