配电网中的水质不是恒定的，而是稳定的 当它通过电源时会发生变化。对管网水质恶化的研究主要是通过建立专门的测量系统来完成的 程序。在启动如此复杂且昂贵的测量程序之前，可以分析现有数据。美国自来水公司 阿姆斯特丹Waternet对处理过的水和水进行采样 在分销网络中定期进行。本文介绍了一个 对该测量项目1990年数据的研究 直到2004年。温度、氧气、溶解有机碳（DOC）， 结果证明，浮游动物是相关的。在更高的温度下， 更多的浮游动物生长，而DOC和氧气浓度 减少此外，浊度之间存在明显的相关性 以及从铸铁干管取样的水中测得的铁。 虽然 分析数据可以很好地概括水质，但事实并非如此 足以评估配水网络中的水质变化。包括3个参考文献、表格、图表。

The water quality in the distribution network is not constant but changes as it travels through the mains. Research on water deterioration in the network is mainly done by setting up special measuring programs. Before starting such a complicated and expensive measuring program, existing data can be analyzed. The water company of Amsterdam, Waternet, samples both the treated water and the water in the distribution network on a regular basis. This paper presents a study of the data of this measuring program from 1990 until 2004. Temperature, oxygen, dissolved organic carbon (DOC), and zooplankton turn out to be correlated. At higher temperatures, more zooplankton grows, while both DOC and oxygen concentration decrease. Additionally, a clear correlation exists between turbidity and iron measured in water sampled from cast iron mains. Although analyzing the data gives a good overview of the water quality, it is not sufficient to assess water-quality changes in the distribution network. Includes 3 references, table, figures.
