Abstract:
The possibility of providing sufficient drinking water has become a difficult challenge in various regions of the world, due to the difficult climate as well as pollution of all kinds (domestic, industrial, agricultural). The objective of this work is to demonstrate and determine the state of groundwater quality in the Hassi L’Fhel region (wilaya of Menéa), which is intended for human consumption and extracted from four different locations in this region (El Motaouassita, Guillal, Hay Boummama and el Kadim wells) which are intended, in the majority of cases, not only for irrigation but also for human consumption, we have carried out at the Ghardaïa ADE laboratory, a physico-chemical (Temperature, Hydrogen potential, Electrical conductivity, TDS, Turbidity, Hardness, Calcium , Magnesium, Sodium, Potassium, Chloride, Bicarbonates, Sulphates, Ammonium, Iron, Orthophosphates, Nitrite.) and bacteriological analysis (Total coliforms, Escherichia coli, Faecal streptococci). The results obtained from these analyzes, gave a neutral to slightly basic water with low temperature values, medium to high conductivities, low turbidity, acceptable mineralization, low content of Calcium, Magnesium, Sodium, Potassium, chloride, sulphates, iron and ammonium. The result of bacteriological analyzes show the absence of all kinds of bacterial contamination. So, the results obtained comply with Algerian standards and therefore, the waters of Hasi L’Fhel are drinkable.
