Mineral water (soda water) is very popular in Germany. Therefore, soda fountains were developed as alternatives to the traditional deposit bottle system. Nowadays, different systems of these devices are commercially available. For several years, soda fountains produced by different companies have been examined at the University Hospital of Heidelberg. In 1998, it was possible for the first time to observe and evaluate one of these systems over a period of 320 days in a series of microbiological examinations. The evaluation was implemented on the basis of the German drinking water regulation (Anonymous, 1990. Gesetz über Trinkwasser und Wasser für Lebensmittelbetriebe (Trinkwasserverordnung - TrinkwV) vom 12. Dezember 1990. Bundesgesetzblatt 66, 2613ff). Initially, the bacteria counts exceeded the reference values imposed by the German drinking water regulation in almost 50% of the analyses. Pseudomonas aeruginosa was also detected in almost 38% of the samples. After a re-arrangement of the disinfection procedure and the removal of the charcoal filter, Pseudomonas aeruginosa was not detectable any more. However, the bacteria counts still frequently exceeded the reference values of the German drinking water regulation. Following our long-term analysis, we would not recommend soda fountains in high-risk areas of hospitals. If these devices are to be used in hospitals, the disinfection procedures should be executed in weekly or fortnightly intervals and the water quality should be examined periodically.
矿泉水（苏打水）在德国非常受欢迎。因此，汽水供应机作为传统押金瓶系统的替代品而被开发出来。如今，这些设备的不同系统在市场上都有销售。几年来，海德堡大学医院一直在对不同公司生产的汽水供应机进行检测。1998年，在一系列微生物检测中，首次有可能对其中一个系统进行为期320天的观察和评估。评估是根据德国饮用水法规（匿名，1990年。1990年12月12日关于饮用水和食品企业用水的法律（饮用水法规 - TrinkwV）。联邦法律公报66，2613页及以后）进行的。最初，在近50%的分析中，细菌数量超过了德国饮用水法规规定的参考值。在近38%的样本中还检测到了铜绿假单胞菌。在重新安排消毒程序并拆除活性炭过滤器后，再也检测不到铜绿假单胞菌了。然而，细菌数量仍然经常超过德国饮用水法规的参考值。经过我们的长期分析，我们不建议在医院的高风险区域使用汽水供应机。如果要在医院使用这些设备，消毒程序应每周或每两周执行一次，并且水质应定期检查。
