Avaliação da qualidade da água do poço semi-artesiano da Universidade Tecnológica Federal do Paraná - câmpus Toledo

Abstract

Water is an essential consumer good for the life of human beings and other living beings, where its availability for use must be linked to treatment parameters according to the intended purpose. Groundwater use has been increasingly sought for economic reasons and quality aspects. Population water needs to be assessed by important analyzes that are determined by national and international laws in order to impose standards so that water consumption does not harm the health of the population. The present work aimed to determine the physicochemical and microbiological characteristics of water present in the artesian well of the Federal Technological University of Paraná, Campus Toledo. During the work was collected water from 4 points: cistern, tap, well and lake of the city of Toledo. The techniques used for microbiological testing were Multiple Tubes, Colilert and heterotrophic bacterial count. For the physicochemical analyzes the pH and turbidity of the samples were evaluated. The results of the multiple tube and colilert analysis showed no contamination by coliform group bacteria, in the analysis of heterotrophic bacteria the plates remained free of colony formation. For the physicochemical analysis the pH and turbidity values of the evaluated samples comprised values within the standards allowed by the current law. The obtained results showed that the samples fit the potability parameters according to the current norms. These results provisionally attest that both the well water and the cistern are suitable for use in water distribution to the campus.
