This study aimed to assess groundwater quality in the Khenifra Province using geospatial techniques, statistical analysis, the Water Quality Index (WQI), and the Organic Pollution Index (OPI). To this end, we collected and analyzed 84 seasonal water samples from 21 sites, including 14 wells and seven springs, from May 2021 to April 2022. Statistical analyses highlighted that mineral content and organic load are the primary sources of variation in groundwater quality, revealing distinct variations in physicochemical parameters that elucidate their interrelationships and underlying influences. The WQI of the studied groundwater ranged from 55.24 to 71, indicating a generally satisfactory quality. Most samples complied with the World Health Organization (WHO) and Moroccan standards, except for potassium and calcium, which greatly exceeded the values recommended by the WHO. However, the OPI ranged from 2.75 to 3.5 value, indicating moderate to high pollution levels, exceeding the Moroccan standards for water intended for human consumption. Furthermore, the spatial analysis identified considerable variability in the distribution of these parameters, with a concentration of variables in the northwest and southeast regions, indicating high density areas. These findings highlight the importance of adopting adequate measures to protect the health of rural populations directly dependent on untreated water sources. Moreover, efforts to protect groundwater from the harmful impacts of human activities need to be redoubled. |
