The quality of drinking water is a powerfulenvironmental determinant for human health. Assured drinking water is afoundation for the prevention and control of waterborne diseases. All over theworld, human population has inadequate access to potable water and use sourcescontaminated with disease vectors, pathogens or unacceptable levels of toxins orsuspended solids. Drinking or using such water leads to widespread chronicillness and is a major cause for death. Reduction of waterborne diseases is amajor public health goal for a civilized society. WQI values are computed forwater quality measures in Torehalla. In the present investigation 71 groundwatersamples have been analysed and interpreted. WQI values in the study area variesbetween 39.6 to 201.7 with an average of 86.4. According to the WQIclassification, about 7% of the total groundwater samples represent excellentwater quality, 69.1% as good, 22.53 % as poor and about 1.37% as very poor waterin quality. The higher percent of WQI values in poor and very poor water qualityclasses is mainly due to geogenic and anthropogenic factors. Although the waterquality is mainly controlled by rocks and soil chemistry, excessive utilizationof agro inputs has also compounded to this problem. The results obtained fromthe study indicates that groundwater is generally suitable for both drinking anddomestic purpose, except in few cases.
