This study was carried out to assess the water quality of the Senegal River by turbidity and Chemical parameters during the rainy season. The 24 samples were collected from 4 stations and sampling was conducted at two different dates, namely 7th and 22nd August 2013. The chemical parameters studied are Ammonia (NH4+), Orthophosphates (PO43-), Silica (SiO2), Oxidizables Matters (OM), Aluminium (Al), iron (Fe), Manganese (Mn), Zinc (Zn) and lead (Pb). The water of Senegal River showed the existence of the pollution from the turbidity during August; corresponding at rainy season. Analysis observation revealed variation in the values of NH4+ from 0.01-1.12 mg/L, PO43- from 0.49- 1.70 mg/L, SiO2 from 0.04- 1.02 mg/L, OM from 1.28-3.84 mg/L, Al from 20- 500 µg/L, Fe from 170- 320 µg/L, Mn from 1- 6 µg/L, Zn from 20-100 µg/L and Pb from 0.5-10.2 µg/L. The use of turbidimetry for assessing water pollution is positive and motivating by its permanence, instantaneous but not sufficient. It is imperative to study the pesticides content in the water of Senegal River to make a good model of treatment.
