ABSTRACT
Background Marine environment plays a socio-economic role of great importance in Morocco. Its coasts which incorporate one of the richest biodiversity in the world suffered from large volumes of liquid waste of several industrial and domestic units. These effluents unfortunately are discharged into the marine environment. Agadir coastline located in the southwest of Morocco is among the famous economical ones of the African continent, but it is characterized by industrial pollution (Canning factories, By-product factories), Old and New ports discharges, tourist factories (hotel discharges, bathing activities) and domestic wastewater. All of these factors have caused heavy microbiological pollution on these coasts (2500 m3 / day is a volume of untreated industrial and urban discharges from Anza city). To solve this problem, two wastewater treatment plants (WWTP): Anza and Aourir were installed in Agadir city. Objectives This study aimed to assess the impact of the installation of these two WWTP onto abiotic and fecal indicator bacterial (FIB) parameters in seawater and to estimate quality of the seawater bathing areas. Methods This study was conducted in the period from January 2017 to December 2018 in three studied beaches belonging to Anza-Taghazout coastline. Six abiotic parameters were measured in situ: Temperature, dissolved oxygen, electrical conductivity, salinity, Total Dissolved Solid and pH and two bacteriological analyzes: fecal coliforms (FC) and fecal streptococci (FS). Results Physico-chemical results show seasonal variations and bacteriological results in three beaches are within Moroccan Standards of bathing water quality and are all ranked B. Pearson correlation test carried out between the abiotic factors and the levels of FIB showed a significant positive correlation between FS and temperature and a significant negative correlation with TDS, while FC show a significant positive correlation with DO2. Conclusion Seasonal variations of physico-chemical results are probably due to climate conditions, and classification of our studied beaches compared to old studies in the same ecosystem is probably related to the installation of the two WWTPs. The fecal contamination in these beaches has three origins: animal origin, mixed contamination origin predominantly human and mixed contamination origin predominantly animal.
Keywords: Abiotic parameters, Bathing water quality, Contamination origin, Correlation, Fecal coliform, Fecal streptococci.
