Abstract


The Guarapiranga Reservoir is one of the largest and the most threatened water source of the Metropolitan Region of São Paulo, supplying water to about 4 million people. The growth of urban sprawl into the reservoir is causing negative impacts on the water quality. Analysis of inorganic material in the sediments of rivers and lakes is an important means of pollution assessment due to they are prone to rapid changes in the composition with the water column. This project collected a 75 cm testimony with 75 fractions (1 cm each) from which inorganic materials were analyzed. Metals and organic matter in this sediment testimonial were evaluated over time using mass balance calculations. The anthropogenic impacts over the Guarapiranga reservoir are discussed.
