Abstract

Introduction: Finding the importance of safe water, developed countries, have
solved many of their health problems. In Iran, as there are not enough regular
available and railways and airways, buses are the main way for transportation.
Pollution of drinking water in those buses is a serious way for spreading waterborne
diseases. This survey has been conducted to assess the quality of drinking
water of Bandar Abbas road ways buses.
Methods: In this descriptive study, 38 samples were taken. MPN test was
preformed with 3 tubes (method based on related standard), residual chlorine was
measured by DPD kit, turbidity was tested by tubid meter and pH was measured
by use of portable pH meter. Test results were presented as descriptive statistical
data.
Results: In all samples, residual chlorine was zero; pH was in range 7-7.5. Out
of 6 MPN positive samples (probably microbial pollution) 2 cases were Volvo
buses, 2 cases were Benz buses and 2 cases were related to water tank of bus
terminal. 24 samples didn’t meet turbidity standard (suitable level).
Conclusion: The survey found there is no relationship between type of bus and
drinking water pollution and possibly water pollution is due to secondary factors,
such as ice pollution, water cooler tank and so on. In addition, secondary factors
can be the cause for a high level of turbidity in some samples.
