The specific objective of the present is to evaluate the human health issue due to the continuous consumption of nitrate-contaminated groundwater among the various age groups of people. In the study, 40 groundwater samples were collected during the post-monsoon season, and the major ions were analysed in a laboratory. Chadha plot revealed that weathering of parent rocks, ion exchange process and leaching of salts from the rocks are primary sources of groundwater contamination. Nitrate concentration varied from 24 to 78 mg/L with a mean of 46.45 mg/L. Nitrogen pollution index (NPI) value divulged that 40% and 17.5% of sample locations are moderately and significantly polluted due to elevated nitrate concentration in groundwater. The human health risk assessment model revealed that health issues are among the various age groups which are infants > kids > children > aged peoples > adults. The nitrate’s identified sources are leaching of salts from the rocks, using synthetic fertilizers, uncovered septic tanks and improper disposal of household waste from the residential area. Therefore, periodic inspection of water supply, health check-up and inspection of underground pipelines are the remedial measures that should be taken to reduce the severe effects of nitrate-contaminated drinking water in the study area.

“…Chadba Plot [2] acknowledge that groundwater can be characterized using different kinds of hydrogeochemical model [48] the plot is used to characterize water into two major category temporary and permanent hardness. For this study groundwater fell within four categories namely; Na + + HCO 3¯, Ca 2+ + Mg 2+ + HCO 3¯, Na + + Cl¯ and Ca 2+ + Mg 2+ + Cl¯ water type as shown in Figure 7.…”

Integration of geophysical and hydrogeochemical methods has been scientifically proven to be useful in vulnerability study and groundwater characterization. Subsurface geoelectric parameters such as resistivity and thickness obtained from geophysical method (Vertical Electrical Sounding VES) was used to determine aquifers vulnerability, longitudinal resistance (ρL) and transverse unit resistance (Rt). Thirty four water samples were collected from groundwater sources for physicochemical analysis.Estimated results from longitudinal conductance (S), (Rt) and (ρL) showed that the values ranges from 0.03 to 2.5mhos, 103.64 to 1964417.8 Ω/m2 and 215.41 to 65731.68 Ω-m respectively. Result from S suggested that 50 % of groundwater is considered to be vulnerable to contamination from the earth surface, while the remaining 50 % is considered to be slightly vulnerable to surface contamination. Further findings obtained from hydrogeochemical analysis such as Gibb’s and Chadba plots revealed that groundwater is highly influenced by rock water interaction,groundwater is classified to be Na+ + HCO3¯, Ca2+ + Mg2++ HCO3¯ , Na+ + Cl¯ and Ca2+ + Mg2+ + Cl¯ water type. Deduction from Soltan classification suggested that groundwater is classified to be of Na+ ˗ HCO3¯ and Na+ ˗ SO4 2¯ water type. Results obtained from Ec and pH suggested that the values were below WHO permissible limit, while result obtained from TDS showed that at some sampling points TDS values were above WHO limit. Based on pH value obtained groundwater within the study area fell within slightly basic to acidic.

“…This is aggravated because groundwater contamination persists and remediation becomes more difficult (Bussard 2005). In this regard, assessing the groundwater quality, understanding its hydrochemical evolution, and identifying its suitability for irrigation are key steps for sustainable water resources management (Brindha and Kavitha 2015;Agca 2014;Zouahri et al 2015, Nyirenda et al 2015El Oumlouki et al 2018;Srivastava 2019;Eyankware et al 2019;Zhou et al 2020;Sunkari et al 2020). These studies have strengthened research on groundwater hydrogeochemistry as a tool for combating pollution and managing these natural resources while guaranteeing the sustainability of agricultural and economic development.…”

Morocco is basically a semiarid country with limited rainfall reducing the opportunities for rainfed agriculture. For feeding its ever growing population, irrigation is required. This study aims to evaluate the groundwater quality for irrigation in the Benslimane region by studying the main influencing chemical elements and characteristics. The main purpose is to provide the farmers and agricultural developers with a clear comprehension of the groundwater status. We focused on the determination and statistical analysis of physicochemical parameters and major elements (electrical conductivity, pH, Na + , K + ,Ca 2+ , Mg 2+ , Cl − , SO 4 2− , CO 3 2− , and HCO 3 −) for 120 samples and the derivation of water quality indices like SAR, %Na, RSC, PI, KR, and MAR, along with graphical approaches such as Wilcox's and Richards's diagrams. Factors affecting groundwater hydrochemistry and quality were also discussed. The results show generally alkaline and shallow waters, with the majority of the samples belonging to the Na-Cl facies. Rock alteration, dissolution, ion exchange, evaporation, and anthropogenic activity are the main factors controlling water chemistry. Most prospected wells indicate high salinity problems due to salt water intrusion. With regard to the suitability of groundwater for irrigation, the majority of wells is of medium to poor quality and is therefore unsuitable. These types of water are found throughout the area, with a significant dominance on the coastal zone. The longterm use of this groundwater would therefore have negative impacts on soil quality and the sustainability of agricultural production. Therefore, we recommend proper agricultural management and irrigation practices in the Benslimane region, in order to increase agricultural production while preserving water and soil resources.
