Abstract

The framing of surface water bodies is an instrument present in the National Water Resources Policy that aims to outline the goal of water quality to be maintained or achieved by water bodies, according to their predominant and intended uses by society. In view of the importance of the framework for water quality planning and the difficulties and possibilities for its implementation reported in the literature, this study aimed to identify them in the hydrographic basins of rivers in the Union’s domain. In this sense, it was analyzed, in the most recent Plans of the nine basins with established committees, the aspects related to the framework; and, in order to diagnose the perspectives of the management bodies on the subject, electronic questionnaires were applied to the committees of the analyzed basins and to the National Water Agency. As a result, there was a lack of framing in accordance with current regulation, namely CONAMA Resolution no. 357/05, in all situations. The main problems identified for this were: lack of fluviometric data, distribution of water quality monitoring points in the basins in such a way as to make analysis difficult, diversity of legislation applicable to the framework in the States in which they are located, water pollution, and lack of articulation institutional relationship between water management bodies, States and municipalities. On the other hand, some potentialities for achieving the framework were verified, such as the implementation of the grant for the use of water resources in all situations, the existence of charges for the use of water resources in five of the nine basins in question, and a greater interaction between the water resources management bodies, States and municipalities in two of the analyzed basins.

巴西地表淡水框架在工会主导的河流:水质管理的挑战和前景
地表水水体框架是《国家水资源政策》中的一项工具,其目的是根据水体的主要用途和社会预期用途,概述水体应保持或实现的水质目标。鉴于水质规划框架的重要性以及文献中报告的实施的困难和可能性,本研究的目的是在欧盟范围内河流的水文盆地中确定这些框架。在这个意义上,在设有委员会的九个流域最近的计划中,分析了与框架有关的各个方面;为了诊断管理机构对这个问题的看法,向所分析流域的委员会和国家水务局应用了电子问卷。因此,没有按照现行的条例,即CONAMA第7号决议制定框架。357/05,在所有情况下。为此确定的主要问题是:缺乏流量测量数据;水质监测点在流域的分布使分析变得困难;它们所在国家适用于该框架的立法多种多样;水污染;水管理机构、国家和市政当局之间缺乏协调一致的机构关系。另一方面,核查了实现框架的一些可能性,例如在所有情况下使用水资源的赠款的执行情况,在有关的9个流域中的5个流域对使用水资源收费,以及在所分析的两个流域的水资源管理机构、国家和市政当局之间更大的相互作用。
