Water quality index (WQI) is a mathematical tool used to transform large quantities of water quality data into a single number which present water quality level. The aim of the present study is to evaluate the quality of Koudiat Medouar Dam in Batna (Algeria) to assess its suitability for drinking purposes. Samples were assessed for ten (10) physicochemical settings namely pH, electrical conductivity, total hardness, nitrate, sulphate, chloride, calcium, magnesium, dissolved oxygen and turbidity. The calculation of WQI was done via weighted arithmetic index method. The WQI values ranged from 99.097 to 174.92 during 2015. It reflected that the water samples were in February in the range of very poor quality and ranged to be in unsuitable for drinking rang in the all other months. The WQI of the present study reveals dam water is contaminated and not suitable for drinking purpose without giving treatment.

Indeks jakości wody (WQI) jest matematycznym narzędziem używanym do transformacji dużej liczby danych o jakości wody w jedną liczbę, która charakteryzuje poziom jakości wody. Celem przedstawionych badań było określenie jakości wody w zbiorniku zaporowym Koudiat Medouar w Batna (Algieria), aby ustalić jej przydatność do celów spożywczych. W próbkach oceniano 10 parametrów fizycznych i chemicznych: pH, przewodność elektrolityczną, całkowitą twardość, stężenie azotanów, siarczanów, chlorków, wapnia, magnezu, rozpuszczonego tlenu i mętność. Obliczenia indeksu WQI wykonano metodą ważonego indeksu arytmetycznego. Wartości WQI zmieniały się od 99,097 do 174,92 w 2015 r. W lutym próbki wody cechowała bardzo zła jakość, a w pozostałych miesiącach woda nie nadawała się do picia. Indeks ustalony w niniejszych badaniach dowodzi, że woda w zbiorniku zaporowym jest zanieczyszczona i nie nadaje się do celów spożywczych bez uprzedniego uzdatniania.
