“…The proliferation of these microorganisms within the oueds is attributed to the unregulated discharge of untreated wastewater into these water bodies, lacking proper treatment measures. This assertion finds validation through the CF/SF ratio, surpassing 1, thereby corroborating the human origin of the fecal matter (Abba et al 2021).…”

The city of Taza, situated in Morocco, boasts a significant ecological heritage. However, a concerning practice of discharging untreated wastewater into the nearby Oueds has raised apprehensions about potential threats to public well-being. This research endeavors to discern the locations most adversely affected by pollution and subsequently assess their environmental condition. By conducting an extensive year-long analysis encompassing physicochemical and bacteriological aspects, we gathered a comprehensive dataset for appraising the surface water quality, utilizing the SEQ-WATER system as the evaluation framework. Four distinct sites emerged as particularly impacted: upstream of Oueds Jaouna and Taza, downstream of Oued Larbâa and adjacent to the "Julien" public dump, and at the confluence of Oueds Rhouireg and Dfali. Employing the GIS-SEQ integration, we meticulously gauged the physicochemical and bacteriological attributes of these sites. Our assessment unveiled readings that surpassed the established Moroccan benchmarks for surface water quality. Notably, the water exhibited pronounced turbidity and elevated levels of suspended particles, including nitrites and sulfates. Additionally, a notable organic load and microbial contamination involving fecal coliforms (E. coli) and intestinal enterococci were observed. These findings underscore the critical necessity for the implementation of efficient wastewater treatment measures within Taza, which would substantially safeguard both the populace and the surrounding ecosystem. It is imperative to conduct further in-depth investigations to validate these outcomes and devise comprehensive strategies aimed at mitigating the potential hazards linked with the compromised state of surface water.

“…Вода, придатна для вирощування риби, має відповідати таким параметрам: стабільний кисневий режим, БСК 5 , відсутність важких металів, пестицидів та інсектицидів, загальна жорсткість не має перевищувати норму для рибогосподарських водойм (Ali et al, 2021;Taslima et al, 2022;Abdelwahab & Thabet, 2023). На екологічну якість води також впливає запах, бактеріологічні показники, прозорість та каламутність (Ajiyel et al, 2021;Holubenko et al, 2023;Khan et al, 2023).…”

Water significantly influences the quality and safety of fish because it is the environment for the life and cultivation of fish. A study of hydrochemical and microbiological indicators of the water of Khadzhibey estuary was conducted; the content of heavy metals in it was determined. In the Khadzhibey estuary, from 2022 to 2023, the water acidity indicator was stable, did not exceed the established hygienic standards for fish farms, and was within the range of 7.6 ± 0.4–8.4 ± 0.3 mg/L, which completely meets the requirements for fish farming. The maximum salinity in the estuary is observed in summer and is 15 % higher compared to winter and spring indicators. The water type of the estuary is mixed with moderate mineralization. It was established that the zinc content in water samples from the estuary exceeds the maximum permissible concentration by 2.6 %. The content of Cadmium, Lead, Copper, and Mercury is constant and does not exceed the maximum allowable concentration for fish farms. An increase in zinc content in water is a stress factor and affects the quality of fish meat. The research results showed that the content of mesophilic aerobic and facultative anaerobic organisms does not exceed the maximum permissible level in muscle tissue cultures of common carp and round bull caught by commercial fishing from the Khadzhibey estuary. Escherichia coli bacteria, Staphylococcus aureus, Listeria monocytogenes, and pathogenic microorganisms were not detected in the samples of the fish subject to the study. According to the microbiological indicators of water and fish, common carp and Round goby caught by industrial fishing in the Khadzhibey estuary are safe and allowed for further consumption by humans and animals.

“…The rivers of Morocco, far from being exempt, bear the burden of this environmental threat, struggling with serious health and economic repercussions. Recent research has drawn attention to the critical condition of many rivers in different parts of the country, highlighting the urgency of addressing this urgent issue to protect the well-being of ecosystems and communities (El Hajjami et al, 2021) and (Abba et al, 2021).…”

In recent decades, the province of Taza has undergone extensive agricultural modernization, marked by an increase in industrial units such as modern oil mills and olive canneries. At the same time, rapid population growth has exacerbated an important problem, the deterioration of the quality of water resources in limited quantities. This study explored the heart of matter by meticulously sampling physico-chemical and bacteriological parameters at eight strategically chosen sites. Conducted in late July 2021, the survey focused on the surface waters of the Innaouene River, providing a timely and insightful examination of the complex dynamics of water quality in the context of modernization and demographic change. This work focused on the determination of physicochemical and microbiological parameters of water. The results of the analyses show that this river is subject to multiple constraints and reaches its tolerance level on most of its sections. A multivariate statistical approach: principal component analysis (PCA) has shown that water pollution in the Innaouene River is mainly related to untreated wastewater discharges into streams. Water quality is considered bad to very bad. Therefore, ecological and health impacts can occur.
