Paleolimnological reconstruction of Guarapiranga Reservoir and diagnosis of water and sediment current quality of SPMR water supply reservoirs facing their management

Abstract

Freshwater is a natural resource that has been under strong pressure, to the point of becoming t one of the greatest XXI Century threatens. Under this water crisis context, the Sao Paulo Metropolitan Region (SPMR) is emblematic. Present research will adopt innovative approaches that consist of the paleolimnology-neolimnology integration, as well as of the use of anthropogenic impact multi-proxies. It is based on three main approaches: a) evaluation of the eutrophication process evolution and the historical anthropogenic impacts of Guarapiranga Reservoir (1906/2009-present); b) multi-proxy characterization in recent sediments of 30 reservoirs circumscribed in the SPMR water supply area; and c) integration of approaches (a) and (b) to elaborate a diatom-phosphorus inference model that will allow estimation of the past phosphorus levels of the Guarapiranga Reservoir water, as well as the positioning of the other reservoirs along the trophic gradient reconstructed. Paleolimnology will include the reference levels (before impact) of Guarapiranga Reservoir, and will be evaluated by 210Pb dated sediment core. Neolimnology will include variables collected from the water column and superficial sediments of 30 reservoirs (20 water supplying ones). Multi-proxy approach will include eutrophication bioindicators (diatoms); granulometry; organic geochemistry (TOC, TP, TN, l3C, 15N) and sterols; and geochemistry of persistent pollutants (metals, PAHs, PCBs, pesticides, hormones, surfactants and a plasticizer). Elaboration of the inferential model will be accomplished by using quantitative diatom species distribution in water and recent sediments. Watersheds of reservoirs will also be analyzed concerning physical environment (geology and geomorphology) and land use and occupation. Above information will contribute towards the proposition of targets to support recovery and/or conservancy, and the elaboration of environmental scenarios, providing innovative subsides for the SPMR water supply reservoir management.
