ABSTRACT
This research aims to evaluate the physicochemical quality of well irrigation water, used by market gardening groups in the District of Laya Doula, CR Nialia, Faranah prefecture, Republic of Guinea. Direct observation and analyses are carried out, direct observation consists of taking stock of the situation and identifying sampling points. The pH, temperature, turbidity, nitrite and nitrate are determined according to standard standards. A mapping of water sources is carried out. Water samples were taken from four (4) wells. The results show that the pH of the wells (PLD1, PLD2, PLD3 and PLD4) comply with WHO standards, and the temperatures are well below 35°C as the upper indicative limit value for water intended for irrigation according to BELGYTI (2009). From the point of view of turbidity, three wells (PLD1, PLD3 and PLD4) out of four are turbid because their turbidity exceeds the limit value defined by the WHO which is (5 NTU). The water samples are not polluted with Nitrite and Nitrate. In short, the results of analyses of the water samples showed that the majority of the physicochemical parameters meet the WHO standards.
