配水系统的各种物理化学特性为铅、铜的浸出提供了有利条件。本研究应用地理信息系统（GIS）和水力模型的分配系统，测试管道材料，管年龄，水年龄，和其他水质参数对铅/铜浸出的影响。本研究基于在北卡罗来纳州州立大学（NCSU）进行的一项研究，该研究使用空间分析和地质统计学分析来测试基于水龄的铅浸出和其他水质参数的影响。研究结果表明，较高水平的第一次抽水铅浓度最有可能发生在1970年至1986年之间建造的铜管道系统的建筑物。建筑物的水龄长和水温高也可能导致铅浸出到饮用水中。在“燃尽”期间将消毒剂切换为游离氯，然后再切换为氯胺，似乎不起作用。
AbstractVarious physical and chemical characteristics of a water distribution system can provide favorable conditions for lead or copper leaching. This study applied geographic information systems (GIS) and a hydraulic model of distribution systems to test the influences of pipe material, pipe age, water age, and other water quality parameters on lead/copper leaching. This study was based on a study performed at North Carolina State University (NCSU) using spatial analysis and geostatistics analysis to test for lead leaching based on water age and the influence of other water quality parameters. Results of the study indicate that higher levels of first-draw lead concentrations most likely occur in buildings constructed between 1970 and 1986 with copper plumbing systems. A long water age to the building and high water temperature also likely contribute to lead leaching into the drinking water. Switching the disinfectant to free chlorine during the “burn out” period then back to chloramines appear not to ac...
