Avaliação dos parâmetros de qualidade da água de abastecimento público na cidade de Macapá, Amapá

Abstract

Water is one of the most important natural resources for the survival of human beings, so the public supply of treated water is essential to meet personal, social, economic, agricultural and industrial needs. The great challenge for Brazilian cities is water quality with the management of their water resources for public supply, due to deteriorating water resources, it is necessary to create measures for the protection and sustainable use of these resources, the ordinance of Consolidation No. 5, Annex XX establishes standards and criteria for the potability of water for human consumption. The Amapá Water and Sewage Company (CAESA) is responsible for supplying and conserving the quality of water for the population, so the water that reaches consumers must meet the quality standards established by law. The present work evaluated water quality parameters at the water treatment plant in the city of Macapá, comparing them with the current legislation, obtaining secondary data on: hydrogen potential (pH); total chlorine (Cl), apparent color (uH) and turbidity (uT) provided by CAESA in the year 2018. Statistical work was carried out for the treatment of data and based on the values obtained it was concluded that CAESA did not meet the limits and values established by legislation.
