“…At least, one-third of the global population rely on groundwater for drinking (Panaskar et al 2016). While groundwater is increasingly exploited in response to population pressure (Bertrand et al 2016;Shang et al 2016;Parisi et al 2018;Cavalcante Júnior et al 2019), increased urbanization (Minnig et al 2018;Tam and Nga 2018;Hughes 2019), industrialization (Zheng et al 2019) and irrigation farming (Panaskar et al 2016;Fabbri et al 2016;Pulido-Bosch et al 2018), only about 22% of the Earth's 37 km 3 (freshwater) is found in aquifers as groundwater (Panaskar et al 2016). Remarkably, about 97% of this quantity is accessible for human use (Panaskar et al 2016).…”

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

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.

“…isotopic data primarily acquired in the purpose of hydrogeological investigations ( -2015Cary et al, 2015;Chatton et al, 2015;Bertrand et al, 2016) but whose the patterns were significantly different from the expected trends, in comparison to Holocene paleogroundwater isotopic records found elsewhere in subtropical conditions. On the basis of these observations, we present new hypotheses regarding Holocene potential paleoecological and paleohydrological trends of the Nordeste.…”

“…In the context of this study, we hypothesized a very limited influence from carbonated matrix i.e. no 14 C dilution, as the deep aquifers mainly consist in siliciclastic sediments Bertrand et al, 2016), and that groundwater flows mostly in closed conditions, similarly to the empirical Vogel´s approach (1970). In such a conceptual framework, the 13 C variability of dissolved inorganic carbon is only attributed to changes in soil 13 CO 2 , depending on the plant type over the recharge area and C speciation (see e.g., Bertrand et al, 2013 and references therein).…”

Such a hypothesis would be consistent with the presence of a rainforest-type ecosystem, similar to the present Amazonian forest, in the currently arid NE Brazil. These observations highlight the potential added value of the groundwater isotopes proxy to discuss the interrelationships of paleohydrological and paleoecological patterns during the Early-Mid Holocene. These new proxies might allow the spatio-temporal extent of the above-mentioned ecological corridors to be discussed. A C C E P T E D M A N U S C R I P T

“…Sampling at scales too large may lead to paradox patterns such as overlapping of both electron acceptors and electron donors without reaction, as detailed in Bauer et al (2008) or Bertrand et al (2016). These authors conclude that there must be one or more additional factors limiting biodegradation.…”
