Solid Waste And Its Interference On The Water Quality Of The Igarapé¹ do Quarenta Educandos Basin - Manaus/Am

Abstract

The “Igarapé do Quarenta”, a stream in Educandos basin, is categorized today as the "worst" and most polluted of the city Manaus, Amazonas, due to the accumulation of solid waste and contamination by heavy metals along its course. The main objective of this research was to verify the influence of solid waste in critical points of the Igarapé do Quarenta, on the water quality of the stream. The area of solid waste accumulation ("garbage") and the water quality in the stream and around and under the bridges of the Igarapé do Quarenta, between the springs (Armando Mendes and Zumbi neighborhoods) and the mouth (Educandos), in the Amazon "summer" and "winter"," were quantified. Water quality was evaluated at each sampling site. The macroscopic analysis demonstrated its importance for the feasibility diagnosis, finding that two of the three springs found are degraded and disturbed. The pH and electrical conductivity values in the sample sites visited, in the upper and middle, of the Igarapé do Quarenta, were very high values in relation to the maximum values recorded in a natural environment in other water streams of Manaus.
