POTABILIDADE DA ÁGUA: COMPARATIVO DAS PORTARIAS GM/MS N° 888/2021 E ANEXO XX DA PC GM/MS Nº 5/2017, OBRIGATORIEDADE E ANÁLISES DE PARÂMETROS FÍSICO-QUÍMICOS E MICROBIOLÓGICOS NAS ESTAÇÕES DE TRATAMENTO DE ÁGUA

Abstract

Basic sanitation is a set of services performed by the government to ensure the availability of clean water for the population. This service is essential for the survival and quality of life of the population. The Basic Sanitation Law, Law No. 11,445, was instituted in 2007, and has undergone several modifications over time. The establishment of physical-chemical, organoleptic and microbiological parameters that indicate water quality are important tools to guide planning and management actions. Ordinance GM/MS No. 888, of May 4, 2021, the Ministry of Health establishes Maximum Permissible Values (MPV) for these parameters for human consumption. The main objectives of this work were to compare the main changes in legislation on physical-chemical and microbiological analyzes on the potability of water for human consumption and to report the main analyzes carried out during the non-mandatory internship carried out at Saneago, in the city of Morrinhos. This work was a documentary research that used the comparative method of the two legislations: Ordinance GM/MS nº 888/2021 and Annex XX of the Consolidation Ordinance GM/MS nº 5/2017. Through the comparative method, we sought to identify and present the main changes in the variables: MPVs, number of samples according to the population served and the frequency of collections, between the physical-chemical, microbiological and organoleptic parameters of the two legislations. The microbiological parameters did not change in relation to their VMPs. However, in Ordinance GM/MS nº 888/2021, the heterotrophic bacteria count was excluded. Of the 110 physical-chemical/organoleptic parameters, 13 suffered a reduction in their VMPs. Four parameters had their VMPs relaxed, allowing higher concentrations in the water. Six parameters were excluded while three were included. The number of samples per collection frequency at treatment exit remained the same for microbiological parameters. As for the collection frequency, all parameters remained the same for surface water sources. For underground springs three have been changed. The non-mandatory internship contributed and helped in the professional experience that was acquired through practical experiences in the laboratory during the 2 years of occurrence.
