The purpose of this study was the quantitative and qualitative analysis of the water in the reservoir and supply system to 27 villages of over 100 inhabitants or those which had a village council, within the Cistierna Health Area.
It was a descriptive, longitudinal, prospective and observational study. We chose certain villages for the number of their inhabitants and where water problems might have more serious effects. Medical personnel, biologists, chemists and primary care ATS-DUE (nursing staff) took part in the study.
The villages were divided into 5 groups. Water was collected at each one on the same day of every month by the same staff. Analysis went on without interruption for the 12 months from February 1, 1991, to January 31, 1992. The water was analysed at the laboratory of the Health and Welfare Territorial Service (León). Beforehand, a survey on infrastructure had been administered to the staff of the 82 neighborhood or village councils making up the Basic Health Area.
None of the villages maintained chlorination for more than 8 months. The majority chlorinated for 2 months (11.11% of the Network). Coliforms were detected in an extremely high number of places. The majority of the samples contained a significant number--to a greater or lesser extent--of fecal coliforms.
Infrastructure and maintenance of the water supply system is inadequate and insufficient. The final verdict from the analyses indicate that, in approximately half the samples taken in this rural area, the water was not drinkable neither in the reservoir nor in the supply network.
本研究旨在对西斯蒂耶纳健康区内100名以上居民或设有村议会的27个村庄的水库及供水系统中的水进行定量和定性分析。
这是一项描述性、纵向、前瞻性观察研究。我们根据居民数量以及水问题可能产生更严重影响的情况选择了某些村庄。医务人员、生物学家、化学家和基层医疗的ATS - DUE（护理人员）参与了该研究。
这些村庄被分为5组。每月同一天由同一工作人员在每个村庄采集水样。从1991年2月1日至1992年1月31日的12个月内持续进行分析。水样在卫生与福利地区服务处（莱昂）的实验室进行分析。在此之前，已对构成基本健康区的82个社区或村议会的工作人员进行了基础设施调查。
没有一个村庄进行氯化处理超过8个月。大多数村庄氯化处理2个月（占供水网络的11.11%）。在极多地方检测到了大肠菌群。大多数样本或多或少都含有大量粪大肠菌群。
供水系统的基础设施和维护不足。分析的最终结果表明，在该农村地区采集的大约一半样本中，水库和供水网络中的水都不可饮用。
