“…Therefore, an appropriate knowledge regarding the hydrochemistry of water is of utmost importance so as to properly evaluate the quality of the groundwater, especially in the rural areas as it significantly affects the usability of the groundwater for irrigation, domestic as well as for industrial needs (Biswas et al 2020;. Several studies (Rabeiy 2018;Aouiti et al 2020;Aravinthasamy et al 2021;Kadam et al 2021;Kamaraj et al 2021;Rao et al 2021;Şener et al 2021) have been conducted earlier regarding hydrochemistry and groundwater suitability for irrigation. The quality of the water used for irrigational purpose directly influences the yield of crops as well as land degradation.…”

Groundwater alone comprises nearly about 80% of the available water for irrigation purpose in Murshidabad and this usage of groundwater for irrigation is yet to increase further in the upcoming years. The present study was carried out to access the groundwater’s suitability for different agricultural purposes in and around Sagardighi block of Murshidabad district, West Bengal, India. Groundwater samples from thirty three different locations around Sagardighi were collected and then tested in the laboratory for various physical as well as chemical parameters such as electrical conductivity (EC), total dissolved solids (TDS), pH, some major cations (Ca2+, Mg2+, Na+, K+, Fe2+) and some anions (CO32−, HCO3−, Cl−). To further delineate the suitable groundwater zones for irrigation practices, the irrigation water quality parameters such as sodium adsorption ratio (SAR), sodium percentage (Na%), magnesium adsorption ratio (MAR), permeability index (PI), residual sodium carbonate (RSC), Kelly’s ratio (KR) were also calculated. Results show that most of the water samples had low to medium salinity, while only a very few of the samples show high salinity. Piper trilinear plot reveals that the water is primarily of Ca–Mg–HCO3− facies type. The SAR value of majority of the water samples in the study area are less than 10, which is within safe limits. RSC values indicate that the carbonate content is extremely low in the groundwater of the study area. Overall, the results indicate that majority of the samples are fit to be used for irrigational purpose. The findings of this study would help decision-makers in developing irrigation suitability planning and groundwater resource management in the future.

“…Poorly soluble salts in irrigation water are precipitated and accumulated on the soil with each successive crop. The PS of groundwater samples is classified into three categories (Doneen, 1954;Kamaraj et al, 2021); Excellent to good (<5), good to detrimental (5-10) and detrimental to unsatisfactory (>10). The PS calculation of the CI water samples in the area investigated (Table 3) gives values ranging from 18.62 to 26.83 meq/l, with a calculated average of around 22.92 meq/l.…”

Groundwater is vital for all living beings and the socio-economic development of arid regions. The present study evaluated the pertinence of groundwater of the continental intercalary (CI) aquifer in the Ouargla region for domestic and agricultural purposes. Sixteen (16) water samples were collected and analyzed for physical parameters, major cations and anions. The appreciation of groundwater potability was compared with the WHO (2017) standards. Agricultural water quality was evaluated using the Irrigation Water Quality Index (IWQI) method and the study of irrigation parameters: EC, SAR, SSP, PI, KR, PS and MAR. The results show that the CI waters are dominated by mixed Ca-Mg-Cl type (56.3%) and Ca-Cl type (43.7%). Natural rock-water interactions, including silicate weathering, evaporite dissolution and cation exchange, were the dominant processes controlling the mineralization of CI waters. According to WHO (2017), EC (100%), T (100%), TDS (100%), Na + (87.5%), K + (100%), Ca 2+ (12.5%), Mg 2+ (18.75%), SO 4 2-(100%), and TH (100%), samples exceed the permissible limit, indicating that most of the groundwater samples do not have good quality for drinking purposes. The calculated IWQI showed that 31.25% of the water samples were in the good category and 68.75% in the doubtful category.

“…A higher hardness value considers Mg 2+ to exceed the quality level (Kamaraj et al, 2021). The Bhavani basin Mg 2+ level for the 1972 decade was 10-148 mg/l and for the 2010 decade 14-120 mg/l (permissible limit 100 mg/l).…”

This research was conducted to examine the drinking (WQI1) and irrigation (WQI2) water quality for the Bhavani river basin using statistical methodologies. The study area geographically covers up to 4207 km2. For evaluating the Water Quality Index (WQI), fourteen groundwater parameters were employed and the data was gathered for two decades (1972–1990 & 2010–2019). The groundwater parameters include TDS, pH, EC, TH, Ca2+, Mg2+, Na+, K+, CO3 2-, HCO3 - , NO3 - , Cl- , F- and SO4 2-. The weightage arithmetic approach was utilized to compute the WQI1 and all the parameters were spatially represented using Arc GIS 10.3 software. To compute the WQI2, the Sodium Absorption Ratio (SAR), Sodium Percentage (%Na), Residual Sodium Carbonate (RSC), Magnesium Hazard Ratio (MHR), Kelly's Ratio (KR), Permeability Index (PI) and Potential Salinity (PI) are employed. The hydro-geochemical features are statistically examined using the Piper trilinear diagram, Gibbs plot, correlation matrix and PCA biplot. The study results suggest that irrigation-and drinking-water quality is worsening from 2% to 44% of the studied region. Statistical analysis also yields satisfactory findings for both decades. According to the geochemical study, the anion and cation ranking for the 1972 decade is Mg2+> Ca+> Na+> K+=Cl- >HCO3 - ->CO3 2->SO4 2-, while the ranking for the 2019 decade is Na+> Mg2+> Ca+> K+=HCO3 - >Cl- >SO4 2->CO3 2->F- . The research indicates viable locations for drinking and irrigation reasons, while the low groundwater quality areas need effective treatment procedures before groundwater utilization.
