“…Piper's diagram helped to understand the geochemical evolution of GW sample and SW and its relationship with dissolved ions [102]. To better interpret the chemical composition of the GW sample [103][104][105][106] and the SW [12,107,108], anions were plotted on the right triangle while cations were plotted on the left [109]. The geochemical evolution of water in general (and GW in particular) can be assessed by determining chemical facies using Piper's trilinear diagram (1944) [110].…”

The processed discharges from Tangier Automotive City’s (TAC) Chrafate Wastewater Treatment Plant (WWTP) contaminate the Jouamaa Hakama groundwater and the Ouljat Echatt river. We aimed to study the unknown interactions between surface water (SW) and groundwater (GW). A total of nine Jouamaa Hakama GW samples and eleven Ouljat Echatt SW samples were taken and analyzed in 2021 and 2022 to determine 16 physical and chemical parameters (pH, temperature (T), electrical conductivity (EC), dissolved oxygen (DO), total hardness (TH), turbidity (TURB), and total dissolved solids (TDS), cations: Na+, K+, Mg2+ and Ca2+, anions: Cl−, CO32−, HCO3−, NO3−, and SO42−). For exploitation of the data, we used a methodology based on hydrochemical modeling (HM), principal component analysis (PCA), Water Quality Index (WQI), Irrigation Water Quality Index (IWQI), inverse distance weighted interpolation (IDW) using Geographic Information Systems (GIS), and regression analysis (RA). We studied the interaction of the surface water of the river (contaminated by discharges from the WWTP) with the shallow groundwater on a strip of 100 m on either side of the river to understand the transverse and longitudinal dispersion of this pollution The investigations indicated that the major ions found in GW and SW were characterized in a different order in the anion list order Cl− > CO32− > NO3− > HCO3− > SO42− and Cl− > SO42− > CO32− > NO3− > HCO3−, respectively, while the concentrations of cations showed the same order for both: Na+ > Ca2+ > Mg2+ > K+. As a result, GW showed in the Piper diagram the type of sodium chloride to magnesium carbonate, while SW belongs to the sodium chloride to magnesium sulfate type. The WQI showed that the river waters are all unsuitable for use (WQI > 100), while the GW is of poor quality (WQI > 76). Moreover, the results of the GW–SW interaction along the river revealed a significant relationship (R² = 0.85), which means that strong circulation and the infiltration of contaminated SW into shallow GW occur in this area. The approaches followed have been proven effective in evaluating water quality for human and animal uses. These results can help decision-makers in the region take suitable management measures to mitigate this environmental problem.

“…Northwestern Algeria, situated within the semiarid regions of the Mediterranean area, comprises four major basins: the Tafna River, Sebkha salt lake of Oran, Macta Basin River, and Chellif Basin river. In this region, there is an abundance of water resources, including surface water, cold groundwater, and hydrothermal water, which have traditionally served as the primary sources of water consumption (Zemour et al, 2023). However, these resources are currently encountering challenges due to increasing demand and overuse, leading to the depletion of large groundwater reservoirs (Famiglietti, 2014).…”

The aim of this study is to assess the relationships between the main stakeholders involved in water management in Sidi Bel Abbes city (western Algeria) to establish pathways for good governance, fair allocation and sustainability of water resources. A multi-stakeholder analysis was performed using the MACTOR method (method of actors and power relations) to analyze stakeholder strategies, alliances, and potential conflicts regarding water management. Data for the study were collected mainly during multi-stakeholder workshops with 6 main stakeholders who are directly involved in managing potable water. A field survey of 329 local households was conducted with the use of supplementary questionnaires. This study proposes that the power dynamics among actors should be considered during the decision-making process to improve collaborative interactions and the effectiveness of stakeholders engaged in water management. The research findings show that the stakeholder’s roles and strategies should be coordinated and strengthened to ensure equitable allocation of water. Technical public agencies deploy management strategies that do not consider water quality as a priority, and they are more concerned with other strategic objectives. Additionally, the stakeholders disagree on many issues relating to water management due to overlapping and conflicting powers, which threatens the quality and availability of water resources. The study also demonstrated that the National Sanitation Office could play an important role as a relay stakeholder and that the Hydrographic Basins Agency should strengthen alliances and commitments with all stakeholders. Enhancing the participation of these stakeholders in water management procedures and empowering domestic water end users, particularly in densely populated residential areas, could help bridge divides and foster a unified approach to achieving sustainable water management objectives.
