The presence of nitrate in sources of drinking water is a matter of concern because of its potential risk for human health. In many countries like Argentina, an increasing proportion of the population chooses to consume bottled water, among other reasons, for lack of water access. The present study was conducted (a) to evaluate the quality of bottled waters by determining nitrate concentration, (b) to relate bottled water quality with water access, (c) to analyze public awareness about bottled water quality and consumption habits of the population in the urban area of Buenos Aires. Two locations were selected, Ciudad Autónoma de Buenos Aires (C.A.B.A.) and Malvinas Argentinas in Buenos Aires Province (PBA), with percentages of water access of 99.6% and 8.8%, respectively. Random samples from both locations (n = 100) were analyzed. A survey was conducted in order to inquire about perception of population on bottled water quality and their consumption habits. In C.A.B.A., no sample exceeded the 45 mg/L limit value in force in Argentina, while in Malvinas Argentinas, 34% of the brands analyzed showed values above it. The survey revealed that 71.7% of people consume bottled water. While people in C.A.B.A. do so mainly out of habit, safety is the priority in PBA.

饮用水源中硝酸盐的存在是一个令人关注的问题，因为它对人体健康具有潜在的风险。在许多国家中，例如阿根廷，由于缺乏水源，越来越多的人口选择饮用瓶装水。进行本研究（a）通过确定硝酸盐浓度来评估瓶装水的质量；（b）将瓶装水的质量与水的获取联系起来；（c）分析公众对瓶装水质量和该国居民的消费习惯的认识布宜诺斯艾利斯市区。选择了两个地点，即布宜诺斯艾利斯省的布宜诺斯艾利斯城（CABA）和阿根廷的马尔维纳斯（PBA），取水百分比分别为99.6％和8.8％。来自两个位置的随机样本（n= 100）进行了分析。为了调查人们对瓶装水质量及其消费习惯的看法，进行了一项调查。在CABA中，没有样品超过阿根廷有效值的45 mg / L限值，而在马尔维纳斯阿根廷，分析的品牌中有34％的样品显示出高于其限值。调查显示，有71.7％的人饮用瓶装水。尽管CABA的人们主要是出于习惯，但安全是PBA的首要任务。
