Dear Sir,

Water is essential for our life; we cannot live without water and we must drink it every day for our health, especially, when our body has an insufficient amount of water. Water that we drink must have the quality to support our health as well as for the transportation of food in our body. The checking of drinking water quality is very important in public health.[1] As reported by Ashbolt, “drinking water is a major source of microbial pathogens in developing regions.”[2] Here, sample collection site for analysis of coliform bacteria in drinking water is Surindra Rajabhat University, Surin, Thailand. The drinking water samples were collected from all available water machines in the university (ten different sites). After that, we took water samples in the university to check the quality of coliform by cultured bacteria in NaCl and Lauryl Tryptose Broth (LTB). In addition, we spent time for 48 h for the culture of coliform by used culture media in the laboratory in the Department of Biology. We had seen that the water was safe enough to drink. This can confirm the sanitation system in the study setting. In fact, the water machine becomes the important drinking water supply source in the city. However, few reports are available on this water source. The quality of the water from the water machine has to be proven. According to the previous report by Schillinger et al., the contamination could be observed and the condition of the water machine was the important factor contributing to the contamination.[3] In fact, the problem of contamination in water or beverage machine can be the source of disease outbreak. Nelms et al. noted that “periodic testing of vending machines is thus warranted.”[4]
