Canadian Council of Ministers of the Environment; Water Quality Index, Weighted Arithmetic Water Quality Index, Drinking purposes, Poor, Unsuitable.


The Water Quality Index reduces the large number of indicators used in the assessment to a simpler mathematical expression allowing easy interpretation of the monitoring data. The Canadian Council of Ministers of the Environment WQI (CCMEWQI) and the Weighted Arithmetic WQI (WAWQI) were used to assess the groundwater quality for drinking purposes in Sabratha City. Ten samples were collected from different sites in the study area. Eleven significant parameters were considered for calculating the WQI such as; pH, total dissolved solids (TDS), calcium (Ca++), magnesium (Mg++), sodium (Na+), potassium (K+), Chloride (Cl-), bicarbonate (HCO3-), Sulfate (SO4--), nitrate (NO3-) and  Total Hardness (HD). The drink water quality analysis by CCMEWQI and WAWQI shows that more than 60% of the samples described the groundwater quality in the study area as poor to unsuitable and can't be used for drinking propose, only 20% of the samples were classified as suitable for direct consumption
