CPA - Opis:
- The study aimed to evaluate the spatiotemporal variation in the physico-chemical and bacteriological quality of Oued Inaouène water in relation to urban discharges that remain the main sources of pollution in the Inaouene basin. During the period from May 2019 to March 2020, seven stations were sampled, six of which are spread along the Inaouène Oued in addition to one reference station that is less affected by urban pollution. The indicators used were: temperature, pH, electrical conductivity (EC), turbidity and dissolved oxygen (OD), biological oxygen demand (BOD5), chemical oxygen demand (COD), Kjeldahl nitrogen (TKN), E coli, IE and TC. The quality data obtained were analysed using multivariate statistical methods (the CPA) and the correlation matrix. The results showed that with the exception of the OT station located upstream of urban discharges, the majority of stations downstream of urban discharges have poor quality during both wet and dry seasons, according to the Moroccan standards.
