The purpose of this study was to evaluate the quality of water for human consumption in Bécal, rural community of México. The presence of total and fecal coliforms, as well as aerobic plate counts in differents places of the water distribution network, in intradomiciliary deep pools and rainwater cistern system were investigated. Results from this set of experiments suggest the existance of local social and environmental factors that open the way for water contamination with organic material in the water sources studied. We demonstrated the necessity of performing a careful sanitary control and proper handling of water for human consumption through programs of systematic surveillance of the water supplies in order to provide good quality water to the population of this rural community. Additionally, it is necessary to perform educational programs about procedures for preservation of hygiene with special reference to prevention of gastrointestinal diseases.
本研究的目的是评估墨西哥农村社区贝卡尔供人类饮用的水的质量。对配水管网不同位置、室内深水池和雨水蓄水池系统中的总大肠菌群、粪大肠菌群以及需氧平板计数进行了调查。这一系列实验的结果表明，当地的社会和环境因素为所研究水源中的有机物质污染水创造了条件。我们证明了通过对供水进行系统监测的方案，对供人类饮用的水进行仔细的卫生控制和妥善处理的必要性，以便为这个农村社区的居民提供优质水。此外，有必要开展关于保持卫生程序的教育项目，特别提及预防胃肠道疾病。
