Avaliação do tratamento de água proveniente de poço tubular profundo na cidade de São Paulo/SP para fins de potabilidade

Abstract

This case study proposed the evaluation of the efficiency of a water treatment route, for potability purposes, from a deep tubular well located in the city of São Paulo. The water quality, and the consequent effectiveness of the treatment, were measured through analysis reports carried out by certified laboratories and meeting the analysis parameters required by Ordinance GM/MS nº 888, which is the Brazilian standard that provides for control and monitoring the quality of water for human consumption and its potability standard. As a methodology, the period from January 2020 to December 2020 was adopted and, at first, through the analysis of raw water from the deep tubular well, the best treatment route was determined for framing the concentrations of the chemical components found. In a second moment, in order to control and validate the treatment route, a battery of analyzes was carried out to certify the quality of the supplied water. The parameters analyzed, as well as the frequency of analysis, complied with the aforementioned ordinance. After the individual analysis of the main parameters and the interpretation of the results before Ordinance GM/MS nº 888, it is possible to affirm that the treatment route in question was efficient, reaching the proposed objective.
