Abstract

Numerous reservoirs in São Paulo State have their watersheds occupied by many urban and agricultural areas uses and fewer remaining vegetation. In general, their watersheds have restricted wastewater treatment. Intense uses, added to incipient sanitary coverage, confer worrying future for these reservoirs, already observed in Billings and Guarapiranga Reservoirs, both located in São Paulo city. These dams have a negative history in the water and sediments quality, culminating with about 40 years of intense applications of copper sulfate and hydrogen peroxide to cyanobacteria control. This scenario suggests that the Brazilian normative are not enough to stop or even reduce environmental impacts on water quality and sediment. This manner is necessary meets its goals of ensuring the availability of adequate water quality standards for current and future generations and promote the rational and integrated use of water resources. In the Water Framework Directive (WFD), the European water resources management system, the water quality is not linked to the use but the ecological quality of the environment. The WFD adopts ecosystem approach in order that water bodies achieve minimal degradation state. In 'good conditions', physical, chemical, biological and hydromorphological conditions have 'slight' deviation from the conditions of the water body without human action. For reservoirs, the scope of the 'good ecological status' would be the destruction of the dam to restore the natural flow of rivers, which is not feasible. Under like conditions the WFD allows to identify and designate artificial and heavily modified water bodies and water bodies, rather than good ecological status for artificial water bodies and heavily modified water bodies the goal is to achieve good ecological potential and good chemical status surface water, taking into account the goals for which these water bodies were created. In Brazil there are few studies based on the WFD, highlighting work of the Laboratory of Limnology (USP, IB, Department of Ecology). The work performed by this group suggests the possibility of adapting the WFD to the Brazilian reality, with regard to ecological aspects. They also suggest that the experience could be strengthened in the São Paulo State, where there is adequate management structure in relation to other regions of the country, with expanded monitoring network and database, numerous expert, consistent laboratories and methodologies, for example. The aim this work is apply the WFD concepts to São Paulo State reservoirs, adapting the WFD to Brazilian reality, as needed. In this research, emphasis will be given to the ecological approach, considering the typology, the establishment of reference conditions, the assessment of ecological status and the analysis of pressures in the basin, mostly. It is hoped to establish reference conditions for each type of water body classified by the typology and establish responsive index to degradation, for establishing the ecological potential of reservoirs in the São Paulo State. Thus this project aims to: investigate the trophic history through the nutrients analysis (nitrogen and phosphorus in water and sediment) and fossil pigments in sediments and to determine reference values for each of three reservoirs of predetermined typology; establish baseline concentrations for some metals in the sediment; investigate the sediment quality, through the historical accumulation of these metals; investigate the suitability of water quality indices based on phytoplankton established by the WFD to Brazilian reservoirs; establish an index of ecological potential for Brazilian reservoirs, based on the positioning of phytoplankton species along the trophic gradient. We also intend to propose the definition of typologies for the water bodies in the state. (AU)
