This work is a contribution to the monitoring of the physicochemical and microbiological quality of seawater on the coasts of Sidi Ifni. Its aim is the evaluation of the quality of coastal waters and the determinationof the degree of compliance with Moroccan standards. The seawater samples were taken between January and June 2021 from three sampling sites (S1: BoumrsaL, S2: Goraizim and S3: Aglou), which were chosen according to several criteria, such as the presence of direct and indirect pollution points and the most frequented areas of swimmers and visitors to the beach. The results of analysis of the physicochemical parameters (Temperature, pH, Salinity and Dissolved oxygen) and bacteriological indicators (Total coliforms, faecal coliforms and faecal streptococci) of seawater presented on the Sidi Ifni ratings show significant spatial and temporal variations with values that do not exceed the guide values of Moroccan standards. This allows the beaches of Sidi Ifni to be classified in category A (Good quality of bathing water). The analysis of variance indicates the difference between the study sites, as well as the correlation test between environmental parameters and contamination indicators showed a significant correlation between faecal bacteria concentrations (TC, CF and FS) with abiotic parameters. While principal component analysis (PCA) confirmed that the site located near the pre-treated wastewater discharge point had significantly high levels of total coliforms, faecal coliforms, faecal streptococci and sites free of wastewater discharge. In an environmental context and as part of the protection of the health of visitors to the beaches of Sidi Ifni, it is recommended to systematically monitor the parameters of faecal contamination and carry out additional studies to assess the effects of seawater pollution on health.
