Abstract

Water quality is an important standard in matching water require and contribute. Abundant degree  of  freshwater  is  prominent  for  biological  requirements  and  is  a  vital  surface  of  incorporated environmental managing and sustainable development. The quality of water indices  evaluation  enterprise  particular  value  which  reduce  the  immense  quantity  of  parameters and simply characterize data. The aim objective of the present study is to assess the  suitability  of  surface  water  of  Bounamoussa  River  situated  in  El-Tarf  city  located  in  the  Algerian’s  extreme  northeast,  for  drinking  purpose  based  on  calculated  water  quality  index  standards.  Per  methodology,  WQI  is  a  significant  parameter  to  check  the  quality of water, and its calculation was carried out by using relations given in the water quality index computation which twelve selected parameters (pH, EC,TH, Ca, Mg, Na, K, Cl, NH₄, SO₄,  NO₂,  NO₃)  have  been  considered,  which  were  measured  at  nine  stations  along  the  river  during  two  sampling  campaigns  (winter  and  summer  seasons).  The  results  showed  that the computed WQI values of Bounamoussa River surface water extend from 32,80 to 65,77 with an average 46,76 in winter and fluctuate from 35,86 to 97,46 with an average of 47,25 in summer, in general, the study region in both seasons is under excellent to good category.  Water  from  almost  all  the  sampled  sites  can  be  careful  as  suitable  for  drinking  purposes. It’s recommended to continue monitoring the water of this ecosystem to facilitate the establishment at all levels to supervise and defend the natural resources of the region.
