“…Maanan and Bloundi suggested that trace elements, except for Co, are derived from the same rock source, bound to iron oxides, smectite, or chlorite clays, as reported (Bloundi et al, 2009;Maanan et al, 2015). Other studies suggested that Pb, Cr, Cu, and Zn are derived from geological and anthropogenic sources such as industrialization (Alloway, 2013;Faouzi et al, 2023), and have an impact It is important to remember that iron overload causes oxidative stress and is a recognized risk factor for the onset of chronic liver diseases (Bloomer et Brown, 2019;Eaton et Qian, 2002), and yet locals still take this water, believing them to be of high quality.…”

The eventual polluting of the Ouichane region's groundwater by heavy metals around an abandoned iron mine was investigated. To reach this aim, the research began with a questionnaire survey to assess local people's use of and appreciation for well and spring water, followed by measurement of spatial pollution load of heavy metals: Al, Ag, Fe, Cd, As, Cr, Co, Zn, Pb and Cu for water samples collected from twelve wells and three spring drinks of water using inductively coupled plasma-atomic emission spectrometry method (ICP). Determining the overall quality of spring and well water for human use was also performed by calculating the heavy metal pollution index (HPI). As result, the survey revealed that 44.90% of the households are not connected to the drinking water network, 97.3% of them use well water, which is highly appreciated, and 88.1% of the population consider its quality to be good to excellent. Meanwhile, the ICP analysis showed that all the water samples contain heavy metals. In fact, the maximum concentrations (expressed in 10 -5 g/l) recorded per element were 9.7 for (Ag), 15 for (Al), 6.9 for (As), 4.5 for (Cd), 5.6 for (Co), 31 for (Cr), 14 for (Cu), 858 for (Fe), 7 for (Pb) and 2.9*10 -5 g/l for (Zn). Moreover, most of the water samples recorded heavy metal values above World Health Organization (WHO) limits, for at least one metal among the ten tested, with high concentrations of iron observed in all samples. The HPI values for the three explored sources (S1, S2 and S3) and for 8 out of 12 wells (P3, P4, P5, P6, P7, P8, P9 and P10) exceed the critical pollution value and identify non-potable water with a high potential of contamination. Consequently, the results of this study raise the question about groundwater around this abandoned mining area, especially in the long term, the use of groundwater could increase because of the succession of years of drought on Moroccan territory and hence may constitute a significant health risk for most of the inhabitants.

“…Textile and food industries are two of Morocco's most developed economic sectors in the Fez region. Unfortunately, these are regarded as one of the largest water consumers and thus the most significant source of environmental pollution due to the discharge of a massive volume of potentially hazardous and toxic wastewater, which has a negative impact and reflection Physicochemical Characterization and Evaluation of the Organic Pollution of Domestic and Industrial Wastewater in the City of Fez Zahra Bouzidane 1* , Ghada Beniaich 2 , Samiha Kaioua 3 , Sanae Rezouki 3 , Dalal Mansouri 1 , Aouane El Mahjoub 1 , Noureddine Eloutassi 4 on tanneries around the world (Boujelben et al, 2019;Bharagava et al, 2018;Faouzi et al, 2023).

Environmental concern implies a degree of basic dynamism aimed at safeguarding ecosystems against any type of pollution and better management of the environment. Wastewater is mainly composed of water and other materials that represent only a small part of wastewater, but can be present in sufficient quantities to endanger public health and the environment, so before discharging wastewater into the natural environment, it is necessary to define its parameters to have information on the composition and qualitative and quantitative characteristics of wastewater and their impacts on the receiving environment. The goal of the conducted work was to determine the degree of wastewater pollution in Fez based on the results of physicochemical analysis of samples collected from various stations in 2021. The temperature varies between 24.6°C and 29.9°C in wet periods and between 26.5°C and 38.3°C in dry periods, the pH is alkaline to neutral with high turbidity levels, especially in wet periods, for dissolved oxygen, the wastewater of the city of Fez is under saturated in oxygen, which accentuates anaerobic fermentation and the release of bad odors, and the average values of the BOD 5 are higher than 100 mg O 2 /l considered. These wastewaters are rated as being of very poor quality. COD values are greater than 500 mg of O 2 /l, which is considered the limit value for direct rejections. Nitrate concentrations are highest in S1, with a value of 12.83 mg/l in the dry period. The recorded contents of orthophosphates and total phosphorus do not vary significantly. The obtained values are higher than the WHO recommended wastewater discharge standards. At the conclusion of this research, it was discovered that the wastewater in the city of Fez is of poor to very poor quality.

“…Textile wastewater generated by various phases of textile processing contains the contaminants that can be harmful to the natural environment if not properly treated [Pandey et al, 2007;Rezouki et al, 2021;Faouzi et al, 2023]. The negative impacts of such discharges include eutrophication, the death of aquatic life, including fish, plants, and animals, and groundwater contamination from contaminants leaching through the soil [Georgiou et al, 2003;Merzouk et al, 2010;Sanae et al, 2021].…”

In this study, the effectiveness of using natural bio-coagulants and bio-flocculants to treat textile wastewater through the coagulation-flocculation method was examined. These bio-based agents have several advantages over chemical agents, including biodegradability, natural abundance, low toxicity, and low cost. A bio-coagulant (holm oak acorn (HOA)) and a bio-flocculant (cactus juice) were used to investigate the capacity for turbidity removal and decolorization of textile wastewater. The UV spectrophotometer was used to characterize the discharges before and after treatment, and the chemical oxygen demand (COD) and biological oxygen demand (BOD 5 ) levels were calculated. Box-Behnken design (BBD) coupled with response surface methodology (RSM) were utilized to optimize the process and reduce turbidity and decolorization in textile wastewater. The obtained results show that under the optimal conditions (0.5 g•L -1 of HOA, 15 mL•L -1 of cactus juice, and a pH of 7), decolorization and turbidity removal were achieved at 69% and 90%, respectively. This study demonstrates the potential of using biocoagulants and bio-flocculants in the treatment of textile wastewater.
