Physicochemical evolution and evaluation of groundwater quality in Mougheul area (Southwest of Algeria)

Abstract

In arid areas, the pressure on water resources and in particular on groundwater resources is on the rise, mainly due to increasing demand and the deterioration of water quality. In this context, the present work aims to follow the annual evolution, between 2009 and 2019 of the physicochemical parameters, and to evaluate the quality of groundwater of the region of Mougheul, by determining the data of pH, TDS, conductivity and the concentrations of major ions ( Ca+2, Mg+2, Na+, K+, Cl−, HCO3−, SO4−2, NO3−) of 07 water points. The results revealed that all the levels of the physicochemical parameters do not exceed the WHO potability standards, except high values were observed at the level of well W6 which exceeds the limits recommended by the WHO (50 mg /l). The diagram of Schöeller and Berkaloff shows that the groundwater has the bicarbonate magnesium facies. The representation of the data on the Piper triangular diagram shows that W6 has the facies chlorinated and calcium sulfate and magnesium and the other water points have the facies bicarbonate calcium and magnesium. SAR values show that the groundwater of Mougheul is excellent for irrigation. The classification according to the Wilcox diagram shows that the groundwater of Mougheul in general is good quality, but the well of W6 water is suitable for irrigation and requires monitoring the evolution of salinity.

Selective, Efficient Removal and Recovery of Phosphate from Wastewater by Promoting the Mass Transfer with Anion Exchange Resin in Redox Flow Deionization Cell

“…Therefore, it is crucial to comprehend the impact of competing anions on the RFDC properties for P removal and recovery. Typically, Cl – ions are among the most prevalent anions, with different concentrations in various wastewater streams . Conversely, the concentration of P typically hovers around 1 mM in many industrial wastewater sources .…”

“…Typically, Cl − ions are among the most prevalent anions, with different concentrations in various wastewater streams. 26 Conversely, the concentration of P typically hovers around 1 mM in many industrial wastewater sources. 1 We investigated the effect of varying Cl − concentrations on the P removal properties by RFDC employing the gel type resin.…”

Hydrochemical characteristics and groundwater quality appraisal for irrigation uses in the Lan-gan region, Northern Anhui Province, East China

“…This water can be used for salt-tolerant crops under favourable drainage conditions (Tiwari et al 2017). As can be seen in the Wilcox diagram (Figure 7) (Sharma et al 2017;Adimalla et al 2018;Mebarki et al 2021), the groundwater samples can been classified into two categories, viz., 88% belong to 'Good to Permissible', and 12% belong to 'Excellent to Good'.…”

“…Groundwater is essential for protecting the ecological environment of arid and semi-arid regions [KENDOUCI et al 2019;KHELFAOUI et al 2020]. The good quality water for drinking purposes is important for future planning and management [MEBARKI et al 2021].
