As part of a case-control study of community-acquired Legionnaires' disease, several factors related to residential water distribution systems and public drinking water systems were studied in the homes of 124 patients with community-acquired Legionnaire's disease and in the homes of 354 controls. The presence of water reservoirs and hot water tanks was studied in residential systems. Factors such as deficient chlorine levels, pipe repairs and other work, water flow interruptions, the use of alternative water sources, inadequate cleaning operations in public water reservoirs, and the position of the home within the public network (and whether this location constituted an endpoint) were studied in public water supply systems. Levels of legionellae in domestic water samples were also measured. Although the use of water reservoirs and hot water tanks promotes colonization by legionellae in residential systems, none of the variables studied seems to increase the incidence of community-acquired Legionnaires' disease.
作为一项社区获得性军团病病例对照研究的一部分，在124例社区获得性军团病患者家中和354名对照者家中，对与住宅供水系统和公共饮用水系统相关的几个因素进行了研究。在住宅系统中研究了水箱和热水箱的存在情况。在公共供水系统中研究了诸如氯含量不足、管道维修及其他工程、水流中断、使用替代水源、公共水箱清洁操作不当以及住宅在公共供水网络中的位置（以及该位置是否为终点）等因素。还测量了生活用水样本中的军团菌水平。尽管水箱和热水箱的使用会促使军团菌在住宅系统中定殖，但所研究的变量似乎均未增加社区获得性军团病的发病率。
