“…Table 3 and Figure 8a show the categorization of collected groundwater wells according to salinity levels. TDS values indicated that about 20% of the groundwater wells have salinity levels less than 700 mg/L, which ensures no restriction for irrigation; approximately 56% have salinity levels ranging from 700 to 3000 mg/L, which mandates slight to moderate restriction for agriculture; and the remaining 24% have a salinity level of more than 3000 mg/L, making it unsuitable and highly restrictive for irrigation [71][72][73], as presented in Table 3. Figure 8a showed the spatial distribution of groundwater quality for agriculture with respect to salinity hazard in the investigated area.…”

Water shortage and quality are major issues in many places, particularly arid and semi-arid regions such as Makkah Al-Mukarramah province, Saudi Arabia. The current work was conducted to examine the geochemical mechanisms influencing the chemistry of groundwater and assess groundwater resources through several water quality indices (WQIs), GIS methods, and the partial least squares regression model (PLSR). For that, 59 groundwater wells were tested for different physical and chemical parameters using conventional analytical procedures. The results showed that the average content of ions was as follows: Na+ > Ca2+ > Mg 2+ > K+ and Cl− > SO42− > HCO32− > NO3− > CO3−. Under the stress of evaporation and saltwater intrusion associated with the reverse ion exchange process, the predominant hydrochemical facies were Ca-HCO3, Na-Cl, mixed Ca-Mg-Cl-SO4, and Na-Ca-HCO3. The drinking water quality index (DWQI) has indicated that only 5% of the wells were categorized under good to excellent for drinking while the majority (95%) were poor to unsuitable for drinking, and required appropriate treatment. Furthermore, the irrigation water quality index (IWQI) has indicated that 45.5% of the wells were classified under high to severe restriction for agriculture, and can be utilized only for high salt tolerant plants. The majority (54.5%) were deemed moderate to no restriction for irrigation, with no toxicity concern for most plants. Agriculture indicators such as total dissolved solids (TDS), potential salinity (PS), sodium absorption ratio (SAR), and residual sodium carbonate (RSC) had mean values of 2572.30, 33.32, 4.84, and −21.14, respectively. However, the quality of the groundwater in the study area improves with increased rainfall and thus recharging the Quaternary aquifer. The PLSR models, which are based on physicochemical characteristics, have been shown to be the most efficient as alternative techniques for determining the six WQIs. For instance, the PLSR models of all IWQs had determination coefficients values of R2 ranging between 0.848 and 0.999 in the Cal., and between 0.848 and 0.999 in the Val. datasets, and had model accuracy varying from 0.824 to 0.999 in the Cal., and from 0.817 to 0.989 in the Val. datasets. In conclusion, the combination of physicochemical parameters, WQIs, and multivariate modeling with statistical analysis and GIS tools is a successful and adaptable methodology that provides a comprehensive picture of groundwater quality and governing mechanisms.

“…Both PH and electrical conductivity (EC 25 ) were measured, calcium and magnesium ions (Ca +2 , Mg +2 ), sodium and potassium (Na + , K + ), carbonates and bicarbonates (CO 3 -2 , HCO 3 -), sulphates (SO 4 ) and chlorides (Cl -) were estimated. As well, the sodium percentage (Na%), sodium adsorption ratio (SAR), magnesium adsorption ratio (MAR), residual sodium carbonate (RSC), potential salinity (PS), permeability index (PI) and the Kelly ratio (KR) were calculated [17][18][19]. In addition to the assessment of the studied groundwater quality for irrigation purposes based on international classifications for each of the following characteristics: EC 25 , SAR, SSP, RSC, MAR, PS, KR [20][21][22][23][24].…”

The study aimed to understand the quality of groundwater in Al-Nimrud region south-eastern part of Mosul city, Iraq. Groundwater samples from 10 wells were collected during the dry season and analyzed for their physical and chemical properties using standard laboratory methods. From the analyzed data, some parameters like sodium adsorption ratio (SAR), sodium percentage (Na%), potenial salinity (PS), residual sodium carbonate (RSC), magnesium adsorption ratio (MAR), permeability index (PI) and Kellys ratio (KR) were calculated for each water sample to know the irrigational fitness and irrigation water quality index (WQI) was applied to the analytical results of the parameters to obtain a single value that was used to rank the groundwater at each well for agricultural uses. The results showed a high levels of salts for most of the water samples studied, where the average values of EC ranged between (1.64 to 5.069) dS. m -1 . Also, the estimated parameters such as Na%, SAR, PI, KR were within the appropriate levels for irrigation, while the values of MAR, PS for most of the samples were within the inappropriate limits for irrigation. Also, the results of the WQI values showed that the groundwater quality falls between the category of severe to low restrictions, therefore the use of most of the water for irrigation in the study area is likely to lead to the problem of salinity in soils with heavy texture.

“…For example, weight was given to 5 for electrical conductivity and Potential salinity due to its effect on soil and plants. In contrast, potassium was given a weight of 1 for its low concentration in river water in all studied sites compared to the global determinants approved for Irrigation (Yasmin et al, 2019) shown in table (2), The irrigation water quality index (IWQI) is also calculated from the following five stages. Where: Wi: relative weight., wi: property weight., Qi: quality rating., Ci: the value of the measured characteristic, Si: the standard concentration of the characteristic, according to international classifications.…”

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.
