Water wells quality assessment using water quality index for the purposes of drinking of M’zab Wadi region

Abstract

The present work aims to assess the groundwater quality using Water Quality Index (WQI), which can be considered as major factor for controlling quality of water with regarded to drinking purposes. Water quality index is used to illustrate the general state of water quality in a single number. This study concerns specifically Daia area upstream region of M'zab valley. Water samples have been collected at eighteen groundwater points in two years 2016 and 2017. Then, different parameters are analyzed and compared with Algerian standards for drinking water. The hydrochemical study shows significant variations in physico-chemical measurement. Also, the obtained results of the water quality index in Daia region show an excellent ranking with 94%, 88% in years respectively.
