The objective of this study is the evaluation of the groundwater’s quality of the region Zegit-Oulmes by analysis of some physico-chemical parameters as pH, redox, conductivity, salinity, solids dissolved, oxygen and temperature. These parameters have been measured by a kind Consort C535 and Hanna Instruments HI 98280 multi-parameter Analyser. The chemical oxygen demand (COD) was measured by a multiparameter photometer HANNA type C 214 (HI 83214), the biological oxygen demand (BOD5) by a Dbometre for five days and turbidity by a turbidimeter.
The electrical conductivity is about 2836,6 ± 229.4 µS/cm, dissolved oxygen about 6.66 ± 3,84 mg/l, about 84,86 ± 56,16 NTU turbidity, chemical and biological oxygen demand are respectively about 166 ± 133.4 mg O2/l and 40.66 ± 29.73 mg O2/l. These results indicate that the groundwater’s quality in Zegit-Oulmes is bad and the measures exceed the national standards, which poses a serious problem for their direct consumption.
