Abstract

The present study was conducted on two rivers in an area with high agro-pastoral activity. The objective of this study was to assess the physico-chemical quality of water subjected to pressure from agro-pastoral activities since 1990. The water samples were collected and analyzed according to standard protocols. For this purpose, water temperature, dissolved oxygen, pH, electrical conductivity, TDS, suspended matter, color, turbidity, alkalinity, total hardness, manganese, nitrites, nitrates, ammonia and phosphates were analyzed. Luminosity, atmospheric humidity and air temperature were also measured to assess their influence on the physic-chemistry of the waters. The results show that the average values of color (325.86 ± 524.69 Plt-Co) and of alkalinity (107.57 ± 20.12 mg/L) are very high; the water temperature (25.79 ± 2.88 °C) is significantly and positively related to the air temperature (32.90 ± 2.96 °C) on the one hand, and significantly and negatively related to the atmospheric humidity (34.43 ± 13.49 %) at p ≤ 0.05. Based on the physicochemical quality of the water, the sampling stations were classified into three classes. Class I groups very good quality water (stations WP1, WP4, WP2 and WP3), class II groups medium quality water (stations WB1 and WB2) and class III represents the worst water (WB3).
