CARACTERISATION DES EAUX DE SURFACE AUX ALENTOURS D’UNE SOCIETE AGRO-INDUSTRIELLE DE MAROUA-CAMEROUN
Journal Title: Larhyss Journal - Year 2017, Vol 29, Issue 29
Abstract
The aim of this work is to study the quality of surface water around Agroindustrial entreprise of Maroua. To attend this objective, a physico-chemical and bacteriological analysis was done. The results show different parameters as follow: the highest nitrate concentrations was observed in S1 (165 mg/L) and the lowest was found for the site S4, in the ammonium concentrations observations was (17.9 mg/L for the site S1, 3.2 mg/L in the site S2, 72.2 mg/L in the site S3, 17.2 mg/L for the source S4 and 87.7 mg/L for the site S5). The iron concentrations was observed as follows, (0.31mg/L for S1, 1.25mg/L for S2, 0.49 mg/L for the S3, 0.48mg/L for S4 and 1.06mg/L for the S5). Those values were very high compared to international standards. This is increasing contamination by human activities and climatic conditions of the region are characterized by flows of very small water during the raining season adds to it the dumping of all industrial effluents in the river without treatment. This has the effect of increasing concentrations of pollutants discharged into rivers then causing a deterioration in the quality of surface water .In view of the above the waters studied are of poor quality.
