“…Retrieved from https ://en.clima te-data.org/afric a/niger ia/kebbi /zuru-38058 0/on 10/06/2019 Figure 3 shows the geological cross section of Sokoto Basin. In terms of geology, the Sokoto Basin is extensively studied (Emujakporue et al 2018;Ette et al 2017;Kogbe 1981;Moody and Sutcliffe 1991;Nwankwo 2015;Nwankwo and Shehu 2015;Onuigbo et al 2017). The sediments of Sokoto Basin were accrued during three main stages of deposition, i.e., the first and last phases were the continental Mesozoic and Tertiary, with a second phase which is the marine Maastrichtian to Paleocene.…”

“…Therefore, groundwater is cheaply found along with low-lying areas and is largely hauled out using handlines from shallow wells particularly in rural areas (Anderson and Ogilbee 1973;Offodile 2002). Groundwater quality studies in Sokoto Basin (du Preez and Berber 1965;Anderson and Ogilbee 1973;Adelana et al 2003;Amadi et al 2015;Ekpoh and Ekpenyong 2011;Ette et al 2017;Toyin et al 2016;, Wali et al 2018a revealed water of excellent quality and of Holocene age (100-10,000 years BP). These studies were carried out in Cretaceous and Cenozoic Sediment sections of north-western and central Sokoto Basin.…”

Hydrochemical characterization of shallow and deep groundwater in Basement Complex areas of southern Kebbi State, Sokoto Basin, Nigeria

et al. 2019

Groundwater under Basement Complex areas of southern Kebbi has been characterized in order to determine its suitability for drinking and irrigation use. Water samples were drawn from shallow groundwater (hand-dug shallow wells < 5 m) and deep groundwater (boreholes > 40 m). Physical parameters (i.e., temperature, TDS, pH, and EC), were determined in situ, using handheld meters. Discrete water samples were obtained for determination of chemical parameters. Results from severalsample ANOVA (Kruskal-Wallis test) suggested that heterogeneity in water table appeared to exert significant influence on groundwater chemistry which is characterized by a significant difference in pH, EC TH, Na + , Zn 2+ , Mg 2+ , PO 4 3− , Cl − , HCO 3 − , SO 4 2− , and NO 3 − concentrations. Also, ions including Fe 3+ , Zn 2+ , Mg 2+ , Na + , PO 4 3− , and SO 4 2− are above World Health Organization (2011) and National Standard for Drinking Water Quality (2007) reference guidelines. Most of the groundwater sources are moderately hard. Groundwater classification based on chloride, EC, and TDS revealed water of excellent quality for all types of uses. However, groundwater classification based on nitrate pollution revealed water of poor quality. Rock mineral is the major mechanism controlling water chemistry, as revealed by the Gibbs model. Most of the water sources have positive Scholler index, indicative of overall base exchange reactions in the underlying aquifers. Such condition was well explained by Piper trilinear diagram, which revealed two types of faces: Ca-Mg-HCO 3 and Ca-Mg-SO 4-Cl. The HCA categorized wells into three groups according to their hydrogeochemical physiognomies. Despite the significant difference in ions concentration and chemical indices, groundwater composition is more influenced by rock weathering than anthropogenic inputs. Groundwater evaluation for irrigation use indicates a significant difference in SAR level which is related to poor permeability index in shallow groundwater. Higher values of Kelly's index and magnesium adsorption ratio threatened groundwater suitability for irrigation use in the study area.

“…Trace element (Fe, Mn, Co, As, Cu, Cr, Pb, Zn, Ni, etc.) concentrations and stable isotope compositions (e.g., δ 13 C CO2 , δ 18 O, δ 2 Η, δ 34 S SO4 , δ 18 O SO4 ) of groundwater depend on multiple natural factors including the aquifer lithology, the quality of the infiltrating water, mineral weathering reactions, groundwater residence time and mixing of groundwater bodies [1][2][3][4][5][6]. Anthropogenic sources of trace elements include infiltration from contaminated soils, leaching from industrial effluents and the dumping of sewage sludge [6].…”

The effect of geochemical processes on groundwater in the Velenje coal basin, Slovenia: insights from mineralogy, trace elements and isotopes signatures

This study investigated the mineralogical and isotopic composition of groundwater and precipitation to identify and constrain geochemical processes within stacked Pliocene and Triassic aquifers in the Velenje coal basin. Scanning electron microscopy combined with energy-dispersive X-ray spectroscopic analysis revealed that suspended matter in the Pliocene aquifer consists of feldspars and quartz, while dolomite, calcite and feldspars are present in the aquifer dewatering Triassic strata. The concentrations of trace elements in Triassic and Pliocene aquifers range from highest to lowest Zn > Fe > Ni > Al > Ba > Mn > B>Li > Mo > As with the majority of trace element concentrations below international drinking water health guidelines. Multivariate principal component analysis indicated that concentrations of Mn, Ba, Eu, Cs, Y, Li and T, pH, conductivity and dissolved oxygen in samples were the best chemical parameter for distinguishing the two aquifers. A significant positive correlation (p < 0.05) was found between Ni, Mn, Co, Zn, As and Mo. Groundwater in the Pliocene aquifer likely has an external source of carbon based on the δ 13 C CO2 values (− 12.3 to − 3.6‰). The groundwater also has detectable levels of dissolved methane with isotopic values (− 77.7 to − 51.4‰ δ 13 C CH4 ; − 247 to − 162‰ δ 2 H CH4) consistent with microbial methanogenesis. The groundwater in the Triassic aquifer has tritium values (up to 4.1 TU 3 H) characteristic of modern recharge (< 50 years), while the lack of detectable 3 H (0 TU) in the Pliocene aquifer is consistent with longer residence times.

“…The decline in the amount of rainfall in the semiarid northern Nigeria due to climate change has made floodplains in these zones to be under pressure from several sources (Anyadike 1983;Hess et al 1995). Ette et al (2017) stated that groundwater is very essential in Sokoto basin due to the decline in the amount of rainfall that falls for few months in the basin area. Also, the sources of surface water in the area usually become unproductive at the peak of dry season.…”

Geophysical characterization and hydraulic properties of unconsolidated floodplain aquifer system in Wamako area, Sokoto State, north-western Nigeria

et al. 2019

The subsurface internal geometry of Rima River floodplain located in northwestern area of Nigeria was investigated using 2D resistivity imaging, vertical electrical sounding (VES) and laboratory analyses. Four profiles were acquired using Wenner array. The apparent resistivity computed was used to produce 2D electrical resistivity pseudosections using RES2DINV software. A total of nine VESs were acquired along the four profiles in the study area with AB/2 of 1 to 100 m. Quantitative interpretation of VES curves was done by partial curve matching and computer-assisted 1D forward modelling with the WinResist version 1.0 software. Five pits were dug along the profiles to confirm the interpreted results from the geophysical surveys. Soil samples were collected from the pits at various depths, and hydraulic conductivity (K) was estimated in the laboratory using the constant head permeability test following standard procedure. Interpretations of electrical resistivity technique show three to four subsurface layers including topsoil, sandy material and clay/saturated clayey materials. The sandy material is believed to be saturated with water with appreciable amount of porosity and permeability. This layer was further confirmed by pitting around the study area. From the laboratory and empirical estimation of K, it was discovered that the K value ranges from 10 −2 to 10 −6 m/s, which shows that the sample is clean sand which is moderately to highly permeable. The grain size analysis revealed from the cumulative plot that the sample falls predominantly within medium-sized sand, which makes the study area a good aquifer system.
