DIAGNOSIS OF WATER QUALITY FROM SOURCES OF THE PARANAVAÃ STREAM – PARANÃ

Abstract

DIAGNOSIS OF WATER QUALITY FROM SOURCES OF THE PARANAVAÃ STREAM – PARANÃ.
Abstract: The diagnosis of water quality in the springs of the Ribeirão Paranavaí micro-watershed is based on the observation of 39 parameters, demonstrating the necessary understanding of the water potability system and the appropriate intervention through the monitoring of physicochemical and microbiological level. This monitoring aims to recover and maintain the protection of the Permanent Preservation Areas. The understanding of the parameters involved begins with the results of the established analyses. For this purpose, five springs were selected as registered locations, with the geographic coordinates of the drainage headwaters, encompassing water quality levels from both rural and urban areas, which show diferences in the maximum allowable values as defined by the National Environmental Council (CONAMA) regulations. The parameters that exceed the limits, such as total dissolved solids and heavy metals in some samples, are highlighted. The water spring environments with vulnerabilities are subject to the adequacy of current legislation in line with national water basin management policies and groundwater well monitoring. Water management experiences are being shared globally for the environmental sustainability of water for consumption by contemporary society. The methodological approach establishes observations for Class I special and Class II, Class 1 and 2 waters, intended for human supply, in accordance with CONAMA Resolution 357. It includes information on the levels from laboratory records, emphasizing, throughout the explanatory trajectory of the established diagnosis, the knowledge and learning for future water quality monitoring programs, considering concerns about the disturbances caused by chemical and microbiological elements to public health.
