The water of the springs: Ain Nechema, Ain Souda, Ras Oued and Ain Maa Bared representing an important resource for the supply of drinking water for the inhabitants of the commune of Ouled Driss (Wilaya of SOUK AHRAS, North-East Algerian). To this end, the present work consists in carrying out a qualitative study of the physicochemical and bacteriological point of view of the spring water based on the Algerian standards of potability of the drinking water and the regulations in force. The results of the physico-chemical analyses showed that these waters are mineralised with a high content of bicarbonates and calcium, compared to the other ions considered. This is linked to the terrain through which the water flows and also to an increase in lead and sodium. However, the results obtained comply with the standards of potability of water except for lead and sodium. As regards bacteriological analysis, the results revealed the presence of indicators of faecal contamination such as: Total Coliforms, Faecal Coliforms and Faecal Streptococci.
