Abstract
A study of the water quality conditions of Sylhet city of Bangladesh and its restaurants was carried out to assess risks to human health. The investigation was based on questionnaire survey of restaurants and laboratory tests on water samples obtained from the restaurants, tube wells of the city and Surma River the two main sources of water supply to the city. The test parameters were dissolved oxygen; conductance, hardness, pH, temperature, turbidity, essential and trace elements, dissolved and suspended solids and coliform bacteria. The quality of sanitary facilities and handling of food in the restaurants were also examined. It was found that the drinking water of each restaurant was contaminated with fecal coliforms and 25% restaurants had unsafe levels of iron in the water supply. Improper solid waste dumping was found as one of the reasons of groundwater pollution. Statistical analysis based on Pearson's correlation coefficient revealed significant correlation between the extent of groundwater pollution and dumping of solid waste effluents in the immediate vicinity of ground water (tube wells). It was observed that 75.69% (coefficient of determination r2= 0.7569) variation in the value of groundwater near the dumping place showed association with variation in the value of water quality within the dumping place. Health risk score for coliform bacteria was 1,474.77, indicating high risk. The results of the study help in enhancing awareness of health hazards of contaminated food among the consumers as well as in drawing attention of health regulatory authorities.
