Contribution à l’étude de la détermination de la qualité physico-chimique des forages de la région de Metlili (wilaya de Ghardaïa).

Abstract

Ghardaia town is part of a dry zone that contains very important underground waters resources which have to be identified and studied to be preserved. For that purpose, we studied the spatiotemporal variation of the physico-chemical quality of the water of three drillings in the town of Metlili during three months, or of January until the month of Mars 2016. The results showed that most of the moderate parameters respect the standards of drinkability of the water according to the WHO; the variation of the concentrations of these parameters is closely related to the nature of geologic substratum.
