Avaliação da qualidade da água em um trecho do Arroio Pinto de São Miguel do Iguaçu-PR

Abstract

This work aimed at evaluates the water quality of the stream Pinto, located in São Miguel do Iguaçu, in Western Paraná. With the intention of completing this project analyzed the pH parameters, Biochemical Oxygen Demand – BOD, Chemical Oxygen Demand - COD, total coliforms, fecal coliforms, besides the assessment of the environmental conditions of the river and the recommendation of viable solutions to improve environmental performance to the surrounding stream. Were chosen three points in the urban stretch to collect water samples and compare the values obtained with the environmental standards set by CONAMA Resolution nº 357/2005. The proceedings of data collection were performed with all the necessary precautions to reduce the risk of contamination of the material and thus more accurate results. The results of the analysis of the pH parameters, total and fecal coliforms, proves them in accordance with CONAMA Resolution nº 357/2005. Already the analysis of BOD and COD in point 1 and 3 results showed out the standards established. Regarding the environmental conditions of Arroyo after field survey of potentially polluting locations, you can see the river became susceptible to pollution, so that this case will be reversed, it requires an continuous work, always seeking viable solutions to environmental problems found.
