In the region of Taza, groundwater is a vital resource for the economy of the region. They are the crucial water resources for drinking water supply of much of the rural population and for irrigation of agricultural land. This work aims to study the physico- chemical and bacteriological quality of groundwater Watershed Oued Larbaâ during the period between April and July of the years 2011, 2012 and 2013. To do this, water samples were taken and different parameters were analyzed on the physico-chemical and bacteriological : electrical conductivity, turbidity , dissolved oxygen , pH, TAC , Na + , K + , Ca2 + , Mg2 + , Cl - , SO42 - , NO3 - , NO2 - , NH4 + , PO43 - , the oxidizability in KMnO4 - , fecal streptococci, coliforms and fecal coliforms . The results show that the water points studied are considered "unacceptable" for consumers and for irrigation; this could be explained by the presence of pollutants in the groundwater recharge.

Abstract
In the region of Taza, groundwater is a vital resource for the economy of the region. They are the crucial water resources for drinking water supply of much of the rural population and for irrigation of agricultural land. This work aims to study the physico- chemical and bacteriological quality of groundwater Watershed Oued Larbaâ during the period between April and July of the years 2011, 2012 and 2013. To do this, water samples were taken and different parameters were analyzed on the physico-chemical and bacteriological : electrical conductivity, turbidity , dissolved oxygen , pH, TAC , Na + , K + , Ca2 + , Mg2 + , Cl - , SO42 - , NO3 - , NO2 - , NH4 + , PO43 - , the oxidizability in KMnO4 - , fecal streptococci, coliforms and fecal coliforms .

Abstract: (french)
Dans la région de Taza, les eaux souterraines représentent une ressource vitale pour l’économie de la région. Elles constituent les ressources hydriques primordiales pour l’alimentation en eau potable d’une grande partie de la population rurale et pour l’irrigation des terres agricoles. Ce travail vise à étudier la qualité physico-chimique et bactériologique des eaux souterraines du Bassin Versant de Oued Larbaâ durant la période comprise entre le mois d’Avril et le mois de Juillet des années 2011, 2012 et 2013. Pour se faire, des échantillons d'eaux ont été prélevés et différents paramètres ont été analysés sur le plan physico-chimique et bactériologique : conductivité électrique, turbidité, l’oxygène dessous, pH, TAC, Na+, K+, Ca2+, Mg2+, Cl-, SO42-, NO3-, NO2-, NH4+, PO43-, l’oxydabilité au KMnO4-, streptocoques fécaux, Coliformes fécaux et Coliformes totaux. Les résultats obtenus, montrent que les eaux des points étudiés sont considérées « inacceptables » pour les consommateurs et pour l’irrigation, ceci pourrait s’expliquer par la présence d’éléments polluants pendant la recharge de la nappe phréatique.
