“…In addition, Na had a significant correlation with SO 4 , indicating mirabilite (Na 2 SO 4 .10H 2 O) due to salt lake (Gao et al 2007). Na showed a moderate correlation with F (0.589), indicating NaF salt due to the discharge of industrial wastewater from the Ajabshir Industrial City to the groundwater sources (Masindi & Abiye 2018). The third principal component (PC3) included No 3 and pH which demonstrated the anthropogenic activities such as the use of fertilizers and domestic wastewater (Gao et al 2007).…”

The evaluation of groundwater quality and geochemistry have an important role in the management of water resources in arid and semi-arid regions. In the present study, the spatio-temporal assessment of groundwater quality and hydrogeochemical processes, as well as, statistical analyses in the Azarshahr and Ajabshir planes located in the Urmia Lake basin were investigated. The results revealed that within six years (from 2014 to 2019), the value of total hardness was higher than the permissible level and the quality of groundwater for drinking was very hard and fresh in both planes. In 2019, 84 and 67% of the samples fell within the range of good to poor groundwater quality in the Azarshahr and Ajabshir planes, respectively. The temporal assessment with the help of water quality index values for both planes revealed a good groundwater quality for the Azarshahr plane and a good to poor groundwater quality for the Ajabshir plane. However, deterioration of water quality was observed in both planes from 2014 to 2019. The level of water quality for irrigation was better in the Azarshahr plane than in the Ajabshir plane, due to the presence of fewer salty sites. In addition, Ca–Mg–HCO3 and rock dominance were identified as hydrochemical facies and controlling factor in the groundwater of both planes, respectively. Multivariate statistical analyses indicated both natural and anthropogenic sources (such as weathering, fertilizers, and wastewater) for hydrochemical parameters. It was suggested to develop a comprehensive regulation to control the entry of pollutants into the groundwater of the study area.

“…Marine impact evaluation. Ionic ratios are widely employed worldwide to understand the seawater ingress along the coastal aquifer domain (Batayneh et al, 2014;Sridharan and Nathan, 2017;Masindi and Abiye, 2018). It is well known that no single variable definitively identifies seawater intrusion; however, by considering various analyses, we can ascertain when fresh groundwater mixes with seawater (Werner and Gallagher, 2012).…”

In order to determine the hydrogeochemical processes and salinity status of the surficial lens of freshwater aquifer in the Lagos coastal basin, physicochemical parameters and hydrogeochemical tools were employed in this study. These tools include existing methods such as Piper diagram, Durov diagram, Gibb's diagram, statistical analysis and geochemical modelling, and the newly proposed cationic contribution evaluation and ionic ratio bivariate plots. The Piper plot revealed that chemical facies is rich in (Ca, Mg, Cl and HCO 3 ) and (Ca and HCO 3 ) for the groundwater in both wet and dry seasons while Mg-Cl and Na-Cl water types characterised the lagoon and the Ocean, respectively. The surficial aquifer is an essentially freshwater in the dry season and partly saline in the wet season due to flash flood, marine aerosol precipitation and infiltration from the surrounding brackish surface waters. The Ca 2þ þMg 2þ vs total cation (TZ þ ); HCO 3 -/Ca 2þ vs Ca 2þ /Mg 2þ and HCO 3 -/Ca 2þ vs Ca 2þ /Na þ plots as well as geochemical modelling indicated that carbonate weathering is the dominant chemical process controlling the groundwater chemistry for both seasons. In a descending order, water-rock interaction, ion exchange and evaporation are the geochemical processes controlling the groundwater quality in the area. Besides the natural processes, factor analysis revealed the imminent influence of anthropogenic activities (industrial and domestic) on the groundwater chemistry indicated by the presence of Mn, Fe, Ni, Cd, Pb, Cu and NO 3 above the permissible limit of drinking water standard, particularly in the wet season. In addition to the successful application of the proposed ionic plots, the study justifies the importance of multiple tools application in the hydrogeochemical deductions and recommends consistent monitoring of the shallow aquifers in the Lagos coastal basin.
