Análise de dureza de água superficial e subterrânea e os possíveis impactos ao uso industrial na cidade de Itumbiara, Goiás

Abstract

The water supply used in the industrial process can be sourced from the public network or through the industry's own collection, from surface waters (rivers, streams, and creeks) or underground sources (artesian wells). This study aimed to analyze and compare the hardness of surface and underground waters in the municipality of Itumbiara, in order to indicate the best collection option for local industries, thus helping to reduce the loss of efficiency in the collection and treatment system due to scaling. The study was conducted in the city of Itumbiara, located in the state of Goiás, during the first and second semesters of 2024. The sample collection procedure took place at two surface water points and one underground point. It was observed that the underground water had a slightly higher hardness, classified as slightly hard, when compared to the soft surface water. The surface waters of the region presented soft values, being considered soft waters that are unlikely to cause scaling in systems. However, when looking at underground waters, the problem could potentially arise, likely due to the type of soil in the region.
