“…The graphical presentation between total cations and Ca 2+ + Mg 2+ exposes all groundwater samples below the equiline (1:1), revealing the increased contribution of alkali metals to total cations (Fig. 5b) (Subba Rao et al 2012). In the graph (total cations vs Na 2+ + K + ), all groundwater samples fall under the equiline (1:1) (Fig.…”

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.

“…The Piper (1944) trilinear diagram is very useful to reveal the water types based on the ionic composition of surface water and groundwater from the different aquifers (Narsimha and Sudarshan 2017a, b; Adimalla and Venkatayogi 2017;Subba Rao et al 2012;Li et al 2012), and it is a very effective tool to identify the chemical relationship in water samples. This diagram contains two triangular charts for depicting the proportions of cations (Na + , Ca 2+ , K + , Mg 2+ ) and anions (CO 3 2− , HCO 3 − , SO 4 2− , Cl − ), expressed in meq/L.…”

“…Amiri et al (2015) have reported that groundwater chemistry and its suitability for drinking and agricultural purpose in central Iran. Moreover, in India and many parts of the world, abundant studies have been carried out to assess the geochemical characteristics of groundwater quality with respect of drinking and irrigation (Kudoda and Abdalla 2015;Adimalla et al 2018a;Murkute 2014;Raju et al 2011;Dimitris Alexakis 2011;Subba Rao et al 2012;Sudarshan et al 2014;Li et al 2017a, b;Jeevanandam et al 2006;Li et al 2012;2014a, b;Cheng Qian et al 2016;Sappa et al 2015;Narsimha and Sudarshan 2013;Salem et al 2015;Sethy et al 2016;He et al 2015;Panaskar et al 2016). Furthermore, a number of researchers have used electrical conductivity (EC), sodium absorption ratio (SAR), per cent sodium (%Na), residual sodium carbonate (RSC) and permeability index (PI) classifications for irrigation water quality in many parts of the country (Adimalla and Venkatayogi 2018;Adimalla et al 2018a;Qian et al 2016;Sappa et al 2015;Narsimha et al 2013a, b;Aghazadeh and Mogaddam 2011;Ravikumar et al 2012;Li et al 2012).…”

The present study confers the chemical quality of groundwater and surface water of Mothkur region, Telangana State, for drinking and irrigational purposes. Mothkur region is geologically occupied by the Archaean crystalline terrain. Most of the population depends on groundwater for their daily needs especially for drinking, house needs and irrigation purposes. For this reason, twenty-five groundwater and five surface water samples were collected and analysed for pH, electrical conductivity, total dissolved solids (TDS), total hardness (TH) bicarbonate (HCO 3 − ), chloride (Cl − ), sulphate (SO 4 2− ), fluoride (F − ), calcium (Ca 2+ ), magnesium (Mg 2+ ), sodium (Na + ) and potassium (K + ). The results are evaluated and compared with WHO and BIS water quality standards. Based on obtained results 32%, 20%, 28% and 4% of groundwater samples are not recommended for drinking with reference to the concentrations of fluoride, TDS, TH and Cl − , respectively. Base-exchange indices and meteoric genesis indices classified 67% and 33% of the water sources as the Na + -HCO 3 − type and deep meteoric water percolation type, respectively. Piper trilinear diagram for geochemical classification indicates 44% and 60% of groundwater and surface water samples of Ca 2+ -Na + -HCO 3 − type and 29% belong to Na + -HCO 3 − types. Multivariate graphical methods have been carried out using the United States Salinity Laboratory diagram, Wilcox diagram, sodium adsorption ratio, per cent sodium (%Na), residual sodium carbonate and permeability index which indicate that majority of groundwater samples are useful for irrigation purposes.Keywords Hydrochemistry · Groundwater quality · Sodium adsorption ratio (SAR) · Per cent sodium (%Na) · Residual sodium carbonate (RSC) · Permeability index (PI) · Mothkur region · South India Electronic supplementary material The online version of this article (https ://doi.
