Avaliação da qualidade das águas do Rio Belém, Curitiba-PR, com o emprego de indicadores quantitativos e perceptivos

The main purpose of this work was to evaluate the water quality of Belem River with two complementary strategies: the use of the National Sanitation Foundation Water Quality Index and the application of perceptive protocols (Human Intensity Index and Habitat Value Index). To access the water quality, 10 points at the main river channel as well as the estuary of its 13 main tributaries were selected. The WQInsf results showed a gradual loss of the water quality from the headwater to its mouth mainly due the presence of domestic effluents from the more densely populated areas located near the center of the city. The application of perceptive protocols showed more variable but predictable results indicating its potential as complementary methods of evaluation.

Restrição ambiental ou oportunidade para o desenvolvimento sustentável? Aquífero Carste na Região Metropolitana de Curitiba

In environmental terms, the expansion of urban areas has become a problem that is more serious than that of population growth itself. To face this challenge, the Organization for Economic Cooperation and Development (OECD) indicates the need for changes in city management with the adoption of participative intervention as a strategy to reduce socio-environmental conflicts and control the effects of pollution on the natural environment. The background of this paper is the formulation of watershed occupation policies in urban contexts. The paper studies the perception of residents and representatives of government institutions about the conservation of karst groundwater in the Metropolitan Region of Curitiba.
