Nd Heshmati [10] employed might be as a consequence of the quite higher spatial variation patternand Na , (Table ,3). SeveralCl- , and spherical model to show the correlation among EC for TDS SO4 2- HCO3 – , research have reported2 . the OK process is the ideal system for mapping groundwater good Pinacidil web quality Ca2 and Mg thatEC: electrical conductivity; TDS: total dissolved solids; Mg : magnesium; DGWQI: drinking groundwater high quality index.The outcomes of OK methodology for mapping DGWQI, EC, TDS, and Mg2 are given in Table 6. The R2 , RMSE, and ME values with the OK for TDS and EC had been close, which may be as a result of the quite high correlation among EC and TDS (Table three). Many studies have reported that the OK process may be the finest technique for mapping groundwater quality indicators [10,12]. Sanches [47] and Ostovari et al. [3] reported the good overall performance ofWater 2021, 13,12 ofthe kriging strategy applying data from 36 and 40 wells. However, the present study was conducted working with good quality data from 70 wells, which provided robust benefits.Table 6. The results of OK for DGWQI, EC, TDS, and Mg2 .

Spatial variations of all DGWQI, EC, TDS, and Mg2 had precisely the same trend; enhancing in the northeast to the southwest of the aquifer. TDS values ranged from 376 mg/L inside the northern parts to 7979 mg/L inside the southern components from the aquifer. Inside the northwestern components, the quantity of TDS and EC was decrease than the WHO typical for drinking, but by moving to the south from the aquifer, the high-quality of groundwater in terms of TDS and EC decreased and groundwater became unsuitable for drinking in line with WHO (2011). The EC worth varied from 50.5 /cm in the northern components to 14,649.5 /cm within the southern parts on the aquifer. The DGWQI worth varied from 46 within the northern to 1314 inside the southern parts of your aquifer. Consequently, groundwater high-quality was suitable in the northern parts and unsuitable for drinking within the southern parts [32]. Geological formations within the northern and central components from the plain are alluvial and Sarvak limestone (Figure 2b), which are really compact, tough, and low solubility [4,48]. The Dorodzan dam located inside the northern part of the internet site charges the groundwater of this area. Whilst within the southeast, the presence of Sarvestan sediments (gypsum-saline) and Hormoz igneous rocks can cause a reduce in groundwater high quality [29,49]. Alvelestat Protocol Furthermore, in this area, gypsum-marl formations containing gray lime and dolomite calcium and magnesium carbonate along with evaporitic sediments cut down groundwater quality [29,50]. Therefore, EC, TDS, Mg2 , and after that the DGWQI inside the southeastern components of Marvdasht aquifer were high. In addition to geological motives, the recharging the aquifer by the Kor River is yet another reason for the low good quality of groundwater within the southern component. Furthermore, the entry of industrial, municipal, and agricultural wastewater reduces the top quality from the Kor River, which ultimately reduces the high quality of groundwater within the southeastern pa.
