Groundwater is a primary drinking, agricultural, domestic, and nondomestic water source in Ethiopia’s Yisr River watershed of the Blue Nile River basin. There has been no systematic investigation of the hydrogeochemical properties of groundwater in the research area. The study investigated the hydrogeochemical parameters of groundwater in the catchment to find out if it is fit for drinking and irrigation. A total of 26 samples of groundwater were collected and analyzed for seventeen parameters, including pH, temperature, EC, TDS, TH, K+, Na+, Ca2+, Mg2+, Fe2+, Cl−, HCO 3 − , CO 3 2 − , SO 4 2 − , F−, PO 4 2 − , and NO 3 − . The data were processed and evaluated using integrated hydrogeochemical techniques, including individual ionic signatures, interionic ratios, and multivariate statistical methods, such as multiple correlation analysis, principal component analysis, and hierarchical cluster analysis. The water quality index (WQI) and Na%, PI, RSC, SAR, EC, TDS, and MH were used to judge the quality of water for drinking and irrigation, respectively. The box plot diagram shows the dominant ions in descending order of Ca2+ > Mg2+ > Na+ > K+ and HCO 3 2 − > Cl- > SO 4 2 − > NO 3 − > F− for cations and anions, respectively. The chemical composition of shallow wells and springs indicates freshwater. At the same time, the deep groundwater wells are brackish. The two-factor loadings (principal component analysis) were used to explain the existence of anthropogenic and geogenic sources. Three clusters are identified in the dendrogram. The third cluster has the most significant linkage distance among all the clusters. This means that the groundwater sample in this cluster is geochemically different from the other two clusters, and that this cluster is made up of only deep wells. Water quality indices showed that water quality ranged from excellent to very poor, with the majority (53.85%) being excellent and 26.9% being good. The results of the calculated indices for agricultural water quality indicated that the water quality in most collected samples was in the good and excellent categories; however, the EC, RSC, MH, and TDS indices in deep groundwater wells were found to be hazardous. The findings of this study are useful for understanding groundwater sustainability for various reasons. However, they are also helpful in supporting water management and protection in the future.

The purpose of this research was to use mathematical models to evaluate Tigris River water quality in the metropolitan area of Mosul (WQI). Starting in November 2021 and continuing through March 2022, researchers will collect 120 water samples from six different locations along the Mosul River before it enters the city of Mosul at Badush Kasbah, north-east of the city, all the way down to the Yarmajeh area, south of Mosul (at a rate of two repeats per month for each site) in order to conduct physical and chemical analyses. In addition, the water quality for irrigation was assessed using the (Sub-index-WQI) model and the Kelly Index, K.R., both of which adhere to internationally accepted standard techniques.According to the results of the study, majority of the standards utilized fell within the acceptable range for Irrigation as defined by (WHO, 2004), as shown by the values of the sub-index index falling somewhere in the (44.82-46.12). Because of this, the Tigris River in Mosul City has a high enough quality to be used for irrigation.

“…One of the most critical aspects of groundwater research is water quality. The hydro chemical investigation shows weather the water quality that is ideal for drinking, change in the water quality will be mainly due to oxidation-reduction reactions and rock-water interaction (4,5) . In the studied area, groundwater is the predominant source of agriculture and drinking purpose.…”

Objectives: To ascertain whether the groundwater in Molakalmur Taluk is suitable for human consumption and it is anticipated that the study will assist regulators and policymakers in taking the proper actions to provide the study area's population with safe domestic water. The study's overall goal is to examine the suitability of groundwater for domestic purposes in accordance to WHO and BIS standards. Methods: The current study was carried out to analyze the water quality and spatial distribution of physicochemical parameters of groundwater in study area. A total of 92 groundwater samples were collected in the study region for study during both pre-and post-monsoon monsoon period, ArcGIS 10.1 was used to create a spatial distribution map based on a geographic information system. The concentrations of various ions like Ca +2 , K +1 , Cl -1 , Mg +2 , HCO 3 -1 , Na +1 , CO 3 -2 , and SO 4 -2 were evaluated as per BIS 3025 (2014) and compared with BIS and WHO standards for drinking purpose. Findings: The Gibbs diagram shows that the two main elements that affect the chemical composition of groundwater are evaporation and rock-water interaction. Weathering of silicate minerals and carbonate minerals are the principal sources of carbonate and bicarbonates. Roughly 68% and 58% of the samples exceeded the permissible level of 500 mg/l for TDS.According to the interpretation of Piper's trilinear diagram, the majority of the water samples fell into the categories of mixed CaMgHCO 3 , MgHCO 3 , and CaCl 2 types, in that order of dominance. The plot shows that alkaline earths correspond to 75% of the samples. Novelty: The major ion chemistry of the groundwater in Molakalmur Taluk has never been studied, and there is no perennial river in the research area. The current investigation makes an effort to investigate if water is suitable for domestic purpose. The study's conclusions will help with the gathering of vital information on the condition of the groundwater in Molakalmur Taluk. The study's conclusions may also be https://www.indjst.org/ 516
