Scarcity of water, pollution load, political issues and rising population has drawn a great attention for proper management of water resources such as groundwater in 21st century. The evaluation of groundwater quality is a critical element in the assessment of water resources. The quality/potability of water that is consumed defines the base line of protection against many diseases and infections. The present study aims to calculate water quality index (WQI) by the analysis of seven physico-chemical parameters on the basis of National Sanitation Foundation to assess the suitability of water for drinking, irrigation purposes and other human uses. In the present investigation, ten ground water samples were collected from various parts of Seraidi municipality area located in the north east of Algeria, Physico-chemical parameters such as pH, temperature, dissolved oxygen, phosphates, nitrates; turbidity and fecal coliform were analyzed. The overall WQI values for all the samples were found to be in the range of 68–86 which reveals a fact that the quality of all the samples is only medium to good and could be used for drinking and other domestic uses only after proper treatment.
