Twenty water samples from road-side restaurants and tea-stalls were collected following the protocol of collection of water samples for the analysis Fecal Coliform Count and Ammonia Concentration by Membrane Filtration Method (MFM) and Ultra Violet Spectrophotometry (UVS). The tests were conducted by The Central Lab of Department of Public Health Engineering, Mohakhali Dhaka. Eleven samples (55%) are found to be moderately risky as per WHO and Bangladesh standard (N=0/100 ml), six samples (30%) are less risky and three samples (30%) are highly risky. The level of Ammonia concentrations of all the samples were within the acceptable limit of Bangladesh standard (0.5 mg/L). Also, antibiotic resistance of the samples were performed using Amoxicillin and Azithromycin which are Penicillin antibiotic and Macrolide antibiotic, respectively.
