“…Other sites generally have lower platinum concentrations. The results concerning the presence of undesirable substances in the water at the stations studied align with findings reported by Moustaine et al 23 in the Meknes region. Who revealed fairly high levels of undesirable substances in the water at the stations observed, ranging from 1.13 to 37.49 mg/L (NO3 -), 0.024 to 1.90 mg/L (NH4 + ) and 0.002 to 0.32 mg/L (PO4 3-).…”

“…The highest values were observed at station S9 with mean values of 2280.5 mL/L (2020) and 1809.16 mL/L (2022), respectively. The results regarding the presence of bicarbonate (HCO3 -), carbonate (CO3 2-), and sulfate (SO4 2-) ions in water are in agreement with those reported by EL Moustaine et al 23 who observed that the concentrations of these ions are quite common and can be used in water quality investigations. These ions are natural components of water and originate from various geological, biological and anthropogenic sources.…”

“…The number of germs at the stations varied from 276. 33 23 and in the Marrakech region 31 revealed that the CT, FC and FS varied from 5 to 3840, 0 to 1320 and 15 to 8660 germs/100 m. In the stations studied and mentioned that the bacteriological quality of the water in the stations surveyed highlights contamination by neighbouring pollution (public rubbish dump, sewage spreading, cattle rearing, existence of septic tanks). In addition, the water in the study area is highly polluted in terms of faecal contamination.…”

“…High concentrations of certain ions may require water treatment to meet quality standards and prevent problems such as scaling of equipment or deterioration in drinking water quality. Hydrotimetric titre (TH), total alkalinity (TA) and total alkalimetric titre (TAC) Significant differences in the hydrotimetric titre (TH), total alkalinity (TA) and total alkalimetric titre (TAC) of the water were observed between the stations studied ( 23 in the Meknes region who revealed an increase in these parameters of the water from the stations observed 7.5 to 52.25 mg/L (TH), 13 to 28.75 mg/L (TAC).…”

In the same way, the Lancet Commission on Pollution and Health has brought to light a sobering reality an estimated 1.8 million deaths worldwide are attributed to water contamination. 7 This revelation underscores the urgent need for comprehensive assessments of water quality to understand the multifaceted dimensions of the challenges posed by polluted water sources. Among the many regions grappling with water quality issues, the Oum Er Rbia River in Morocco stands out as an essential focal point for scientific inquiry. [8][9][10] As an indispensable source of water for agricultural, industrial, and domestic purposes, the Oum Er Rbia River plays a crucial role in sustaining the livelihoods of the communities along its course. 11 However, the escalating pressures of anthropogenic activities and environmental changes on this vital waterway necessitate a thorough and multifaceted examination of its water quality. 12,13 Several studies have revealed that some natural processes, such as weathering, precipitation, and soil erosion, play a pivotal role in shaping the quality of Oum Er Rbia River water. 10 Weathering of rocks contributes minerals and ions to water bodies, influencing their chemical composition. 14 Precipitation can alter the balance of nutrients and pollutants in the water, while soil erosion transports sediment and contaminants into rivers, affecting their overall quality. Understanding these natural processes is crucial for distinguishing between baseline conditions and anthropogenic impacts on water quality. 15,16 On the other hand, the influence of human activities on the Oum Er Rbia River water cannot be understated. Anthropogenic sources, including agricultural, urban, and industrial activities, significantly contribute to the degradation of surface water quality. 17 Agricultural runoff introduces pesticides, fertilizers, and other agrochemicals into rivers, altering nutrient levels and posing threats to aquatic ecosystems. 11

Groundwater in the Saïss Basin is an important resource economic and social for the region. They are also the reservoir of an original biological diversity. The subterranean aquatic fauna is to date largely unknown in the Meknes region. It, therefore, represents both a significant part of the national natural heritage and an essential part of the regional natural heritage to be taken into account when conservation measures are considered. Eight wells and two springs were investigated between February 2013 and February 2014. The study was conducted in three localities in the surroundings of Meknes (Meknes, El Hajeb, and Agouray). In fact, Amphipod distribution data is based on unpublished data from my thesis work. Most hypogean taxa are crustaceans, principally the Amphipoda. This research work is a contribution to the knowledge of Amphipoda (stygobionts) collected from the Meknes aquifer. Among the subterranean Amphipoda, species belonging to the genera Metacrangonyx and Pseudoniphargus, which have never been described previously, are limited to a single locality (Agouray), typically found in Wells W4 and W5. In addition, the first record of (Metacrangonyx sp, and Pseudoniphargus sp1 and sp2.) for the stygofauna of the Meknes aquifer was also recorded. These results represent an important contribution to regional biodiversity and finally to complete the inventory of the stygofauna of Morocco.

The Zagora region heavily relies on groundwater as a crucial water resource for a range of human activities. Mining activities can have significant impacts on groundwater quality in the areas surrounding mining sites. The primary objective of this study is to analyze and evaluate the effects of pollution on the quality of groundwater in the Zagora area, with a particular focus on mapping and identifying its sources. It is based on the use of Geographic Information Systems (GIS) and the spatial variation of the physico-chemical parameters of the studied water sources. Assessing the physico-chemical quality of groundwater in Zagora, involves evaluating several parameters that can affect its quality. These parameters include temperature (T°C), pH, electrical conductivity (EC), dissolved oxygen (O2), chlorides (Cl−), sulfates (SO4 2−), nitrates (NO3 −), nitrites (NO2 −), ammonium (NH4 +), and orthophosphates (PO4 3−). The results of the physico-chemical analysis have shown that, the electrical conductivity ranged from 501.59 to 3173.92 μs/cm, while sulfate concentrations ranged from 91.87 to 363.02 mg/L. The spatial distribution of the results indicates that the water samples were collected from different locations, and there are variations in the levels of parameters analyzed. Some of the parameters, such as electrical conductivity, and sulfate, have higher levels in some locations compared to others, indicating potential sources of pollution or natural variability in the water composition. The GIS analysis also revealed that the areas with poor water quality were clustered around specific locations, indicating potential sources of contamination. Therefore, further investigation and monitoring of the water sources may be necessary to ensure safe and healthy water consumption.
