Abstract
The present work aims to evaluate the physical and chemical quality of groundwater in the plain of Bahira pouring in Oum Errabia and on the other hand prevent the risk of alkalization and salinization in the study area. 11 water points were sampled with 22 samples distributed as follows: 11 samples in the period of February 2017 and 11 samples during the period of August 2017 for pH, conductivity, eight major chemical elements (NO3–, Cl-, Na+, HCO3–, Ca2+, Mg2+, K+ and SO42-). Also, Piper, Scholler and Wilcox diagrams were used. The results show the water wells P1, P2, P4, P5, P8 and P10 are characterized by geochemical facies sodium chloride and potassium or calcium sulphate and chloride-facies and calcium and magnesium sulphate to the wells P3, P6, P7, P9 and P11. According to the Wilcox diagram waters are good, acceptable for agriculture according to the distribution of wells in the area. The analysis of the overall water quality revealed that contents of bicarbonates, calcium and sodium exceed the standards.
