Avaliação da qualidade ambiental dos rios pertencentes à bacia hidrográfica do Rio Campinho na Zona Oeste da cidade do Rio de Janeiro

Abstract

The Campinho River Basin (CRB) is located in the West Zone of the City of Rio de Janeiro, passing mainly through the Campo Grande neighborhood and surroundings. Like the entire hydrography of this region, the rivers of this basin are polluted and swallowed by the urban network that has grown without taking into account its survival, but despite the disregard for the CRB its socio-environmental importance is indisputable. In this way, the present research, after having carried out a general bibliographical survey of the basin, including its geographic characteristics and socioeconomic realities, listed its main rivers, in which a photographic record was carried out in its accessible stretches and applied the Rapid Assessment Protocol (RAPs) of Rivers, aiming to monitor their environmental qualities, classifying them as a water body with a natural, altered or impacted level of disturbance. RAPs is an instrument that was developed based on national and international studies aimed at promoting public awareness of the state of preservation and/or degradation of water bodies (rivers, lakes, canals, etc.) and thus providing subsidies materials of community origin for claiming improvements in sewage treatment and public policies for the preservation and recovery of water in rural and urban areas. The RAPs was applied in 9 rivers of the CRB and the obtained results confirmed that these rivers are with an impacted disturbance level. Soon, as a way to encourage the recovery of the CRB, the Digital Booklet “Águas da Zona Oeste” was prepared, which can be made available online free of charge, informing and raising awareness among the interested population about the importance of preserving water for the maintenance of animal life. and plant life of the CRB, as well as the quality of life of residents who live in its surroundings and who suffer year after year from health-related problems, unpleasant smells and increasingly frequent floods.
