“…Indeed, the bacteriological quality of the water in the sources studied reveals contamination of the water table. This could be due to human domestic and agricultural activities, the existence of all types of waste and uncontrolled public dumps [11,19].…”

“…The challenge facing the regions of Morocco, especially rural areas, is the protection of the quality of groundwater resources. The water sources of the aquifer in the Al-Hoceima region are known for their low piezometric level and, consequently, for their easy and uncontrolled exploitation [10,11]. Indeed, the lack of drinking water supply in certain rural areas or among certain fragile categories of the population pushes them to use water sources for all purposes, including drinking.…”

The purpose of the water sources study according to the opinion of the users in the region of Al-Hoceima, is to present a classification of investigated sources according to physico-chemical and microbiological quality, and to compare the obtained results with the sanitary survey taken from users. The region’s groundwater is known for its low piezometry and, consequently, for its easy and uncontrolled exploitation. Indeed, the lack of drinking water supply in several rural areas or among some vulnerable categories of the population forces them to use water sources for all purposes, including drinking. Moreover, in urban areas and with the availability of treated drinking water, people resort to supplying water from a source as traditions and cultural customs of the users predominate. The public survey results in this study confirm, according to the majority of witnesses, that drinking from these sources is continual, as 50% of the consumers live in the area and they do not have any digestive or intestinal problems; these water sources are more frequented in summer and at weekends. Furthermore, the majority of respondents consider these waters to be healthy and not subject to chemical treatment, and they represent a natural heritage with a good reputation among the population of the region.

“…Moreover, the high concentration of this element is observed in the area surrounding the urban city of Imzouren which strongly suggests that it originated from sewage leachate. It is worth noting that traditional pit latrines are more commonly used in Morocco's rural and semi-rural areas (Mchiouer et al, 2022).…”

For effective coastal aquifers management, it is strongly required to effectively analyze seawater intrusion (SWI). This study used an integrated approach of hydrogeochemical, statistical, geological, and geospatial techniques to assess the extent of SWI in the Ghiss-Nekor aquifer by evaluating the physicochemical parameters of 52 groundwater samples. Two main groundwater facies were identified, Na-Cl (38%) and Ca-Mg-Cl-SO4 (62%). The correlation matrix and a principal component analysis (PCA) depicted that the high salinization in the study area is influenced by both geogenic and anthropogenic factors, including a potential mixing with seawater. A single indicator or a small number of techniques were insufficient to evaluate SWI owing to the multiple causes of salinization in the study area. As a result, we coupled various geochemical indicators with geospatial methods to assess this complicated phenomenon. Accordingly, several ionic ratios (Cl/HCO3, SO4/Cl, Na/Cl, and Mg/Mg+Ca) and SWI indices (GQIswi and SMI) were overlaid to generate the final map that highlights the regions prone to SWI. Most of the SWI spots were discovered within two kilometers or less from the coast. The saline water detected far from the coast was interpreted as the encroachment of seawater from the Souani area being trapped where the clay-marly substratum is deep. These results support the application of geospatial tools to manage groundwater resources in water-stressed areas with complex aquifer systems, by combining various ionic ratios and indices. These findings will assist decision-makers in the Al Hoceima region in developing suitable groundwater management plans and strategies.

Its occurrence in groundwater might be attributed to anthropogenic operations such as the excessive use of fertilizers or sewage seepage(Wang et al, 2022).…”
