Abstract: It is not possible having a healthy promoted community without access to safe potable water. Drinking water for potable should be desirable in addition to chemical quality, It should be desirable as a Microbiological. Quality testing of water usually done based on detection of total coliform and fecal coliform. when water is transferred due to unsuitable conditions, from a reservoir to another, there is the possibility of secondary contamination that is for drinking water of public vehicles. In case of contaminated water, there is a serious risk in Spreading of Diseases transmission by water. With this aim, this study has been done about quality of drinking water In Buses of Yazd City Terminal. Methods: This Research is a Sectional- Descriptive study. For this study samples, have been taken as randomly from Buses in Terminal of Yazd. Total number of buses was 117 that 20 percent of those were selected as samples(24 samples). Total coliform, fecal coliform (E. Coli), Bacteria HPC, pH, turbidity, Electrical Conduction (EC) & temperature was measured .The data were analyzed in Excel & SPSS environment. Result: Result of this study showed that in 34.78% of total samples positive probably steps, 13.04 % of total coliforms positive and 4.34% is also positive for fecal coliforms. Similarly about of Bacteria HPC that is 52.17% more than 300, 34.78% less than 300 and 8.69% as SPR or large range between Agar and Bottom Plates respectively. Turbidity of 21.7%, more than 1NTU and less than 5NTU, 78.2% less than 1NTU are recorded. All samples, turbidity have been less than Iranian Approved Standards and World Health Guidelines. 100% of cases residual chlorine was zero, which is not acceptable. pH and temperature, in range 7.5 to 8.5 and 13 to 18 Degree Centigrade respectively. The pH according to the World Health Guidelines in range of suitable for drinking that 60.87% is in range more than 8 and 39.13% less than 8.
