Alternativas para a conservação de mananciais de abastecimento público: estudo de caso na bacia do Rio Ernesto, Pitanga-PR

Abstract

In view of the theme of Water Resources Policy Instruments, this work integrates the legal aspects related to the areas of public supply sources and the need to seek alternatives to conserve them. Based on the research and bibliographic survey, the Protocol for the Conservation of Spring Area (PCSA) was elaborated as a product of this work. The methodology for the elaboration of the PCSA was based on the adaptation of a rapid assessment protocol, which allows the survey of the current situation and the measures to be adopted for the conservation of these areas. These measures were based on the criteria of state and federal legislation, since the municipality does not have specific legislation for the management of the source. The protocol proved to be an efficient tool when applied to the Ernesto river, a source of public supply in the municipality of Pitanga-PR. According to the results obtained, the tool made it possible to find conservationist measures to be adopted in 3 of the 4 points analyzed, which were classified as altered and impacted, mainly due to the lack of Permanent Preservation Areas, irregular use of the soil and the presence of solid residues and liquids in water in some of the observed locations.
