“…The remaining 28% of the waters plot within the rock dominance field, reflecting some form of structural control leading to higher resident times and effective mineral dissolution processes. Plots of Na versus Cl have been used to identify the mechanism for acquiring salinity and saline intrusions in aquifers (Zhu et al, 2008;Singh et al, 2005). Generally, evaporation causes an increase in the concentrations of chemical species in water.…”

“…The excess of Ca + Mg over bicarbonate in the waters indicates some extra source of these ions, and a demand that part of these excess . Asides carbonate weathering, silicate weathering (chiefly plagioclase and feldspar), evaporite dissolution can be possible sources of Ca 2+ and Mg 2+ in water (Ettazarini, 2005;Singh et al, 2005). The excess of bicarbonate over Ca + Mg for samples from the wet season requires that part of the alkalinity should be balanced by alkalis (Na + K).…”

Hydrogeochemical study of the fractured/weathered basement of the Oban Massif, southeastern Nigeria has been carried out. Results indicated that concentrations of major cations and anions exhibited the following order of abundance: Ca>Na>Mg>K and HCO 3 >SO 4 >Cl, respectively, with minor variations across sampling seasons. Ca-Na-Cl-SO 4 and Ca-Mg-HCO 3 water types have been identified as major facies, resultant from congruent influences of weathering (mainly silicates), ion exchange processes, and water mixing.Keywords: groundwater; cation; anion; weathering; ion exchange; Oban massif; Nigeria. Química das águas subterrâneas do Maciço Oban, Sudeste da Nigéria RESUMOEstudo hidrogeoquímico do embasamento fraturado / intemperizado do Maciço Oban, sudeste da Nigéria foi realizado. Os resultados indicaram que as concentrações de cátions e ânions apresentaram a seguinte ordem de ocorrência: Ca> Na> Mg> K e HCO3> SO4> Cl, respectivamente, com pequenas variações entre as estações de amostragem. Os tipos de água Ca-Na-Cl-SO4 e Ca-Mg-HCO3 têm sido identificados como os principais fácies, resultantes de influências congruentes de desgaste (principalmente silicatos), processos de permuta iónica e água de mistura.

“…Hydrogeochemical processes help to unravel changes in surface water quality relating to water-rock interaction or anthropogenic impacts (Singh et al 2005;Kumar et al 2006;Franz et al 2014;Nganje et al 2015;Kamtchueng et al 2016). The geochemical properties of surface water also depend on the chemistry of the recharging source as well as the various geochemical processes occurring within the drainage basin.…”

Seasonal Hydrological Inputs of Major Ions and Trace Metal Composition in Streams Draining the Mineralized Lom Basin, East Cameroon: Basis for Environmental Studies

et al. 2017

Purpose The aim of this study is to assess the seasonal variation in major ion distribution patterns and identify the origin and geochemical behavior of some trace metals of streamwaters bathing the mineralized Lom Basin. Methods Eighty-one water samples were collected during the dry and wet seasons and analyzed for major ions using AAS and 12 trace metals (Fe, Mn, V, Cr, Co, Ni, Cu, Zn, As, Cd, Pb, Hg) by ICP-MS. Results All physicochemical parameters besides pH and Cl -varied narrowly between both seasons. No seasonal variability was observed for Cl -given its conservative nature, while NO 3 -levels decreased in the wet period due to the dilution effect. Similarly, SO 4 2-concentrations were low for both seasons reflecting the dissolution of low sulphide minerals associated with gold deposits. In contrast, the concentration of Ca 2? , Mg 2? , Na ? , K ? and HCO 3 -slightly increased during the wet season as they are flushed from the soil layers by rain. Water samples had very low concentrations (\ 1 lg/l) of V, Cr, Co, Cu, Zn, Cd, Pb and significant concentrations of Fe and Mn.Conclusions The seasonal regime of streamwater chemistry is controlled by groundwater supply of major cations and HCO 3 -from chemical weathering, leaching of ions from surface soil layers during precipitation and dilution of nitrate by surface runoff during the wet season. In this tropical basin, low acidity and trace metal loadings revealed lateritic weathering of sulphides, entrapment of trace metals in Fe and Mn oxides and leaching into deep groundwater. Although the streams have not been impacted, these findings may guide policymakers for water chemistry evaluation in Cameroon.

“…However, the impact of the anthropogenic activities, habitat degradation, exotic species introduction, water diversions, pollution and global climate change are the main causative agents for the aquatic species rapid decline. Reservoirs play a very important role in the geochemical cycling of elements and influence the chemical composition and material transfer of the river system (Abhay et al, 2005). They are of high ecological, economic and recreational importance (Carol et al, 2006).…”
