The microbiological quality control of water for human consumption of parameters relevant as E.coli and total coliforms does not start on the field despite the existence of test methods that could make it possible. One of the things that makes this difficult is the possibility of initiating an effective and reliable incubation at the sampling site. The appearance of isothermal media with phase change materials solves this limitation. When phase change materials combine a relatively high melting heat with a suitable melting temperature adapted to the application temperature, they become excellent materials for thermal protection and for thermal energy storage. Starting the test at the same sampling point means that the effective times to obtain a result are shorter, improving water quality control. On the other hand, operationally, it also allows longer sampling routes. Both aspects are essential for managers responsible for controlling water quality for human consumption. In this work, the evidence that demonstrates the feasibility of this approach is presented.
尽管存在可以实现的测试方法，但饮用水中与大肠杆菌和总大肠菌群等参数相关的微生物质量控制并没有在源头开始。使得这变得困难的原因之一是在采样点开始进行有效且可靠的培养的可能性。具有相变材料的等温培养基的出现解决了这一限制。当相变材料将相对较高的熔化热与适合应用温度的合适熔化温度结合使用时，它们就成为热保护和热能存储的绝佳材料。在相同的采样点开始测试意味着获得结果的有效时间更短，从而可以改善水质控制。另一方面，从操作上讲，它还允许更长的采样路线。这两个方面对于负责控制人类饮用水质量的管理人员都是至关重要的。在这项工作中，提出了证明这种方法可行性的证据。
