Abstract

This study aims to assess marine pollution related to liquid effluent discharges from stormwater drainage channels. The methodological approach consists of a literature review, field visits and observations, interviews with resource persons, sampling, and analysis of physicochemical and biological parameters at the Camberene Wastewater Treatment Plant. The results obtained show that the liquid effluents discharged at the Soumbédioune warf are of domestic origin. With 309.28 mg/L of BOD5 and 1267 mg/L of COD, the concentrations of the physicochemical parameters of the waters of Canal are well above the Senegalese standards for the discharge of liquid effluents into the natural environment. The concentration of fecal coliforms of about 11.3 105 FC/100 ml largely exceeds the limit of the new European directive on bathing waters (2006/7/EC) which is of the order of 200 FC/100 ml for excellent quality bathing waters. The liquid effluents from Canal IV must undergo a treatment process in a WWTP before being discharged into the sea.
