Considerando a grande importância do Reservatório de Itupararanga para o abastecimento de água para a população da região de Sorocaba (SP), este trabalho teve como objetivo principal avaliar sua qualidade da água de acordo com os seguintes parâmetros: profundidade, condutividade elétrica, temperatura, pH, oxigênio dissolvido, Ca, K, Na, Mg, Al, Fe, Zn, Pb, Mn, Ni, alcalinidade, cloreto, nitrato, sulfato, fosfato. Além disso, as variáveis físicas e químicas foram analisadas em dois diferentes pontos de amostragem e períodos durante no ano 2007. Os resultados indicaram que o ponto de amostragem mais a montante (P1) é o mais afetado pelo uso e ocupação do solo da bacia do Alto Sorocaba e ao longo do Reservatório de Itupararanga, as concentrações da maioria dos cátions e ânions analisados diminuem a jusante, melhorando a qualidade das águas deste reservatório. Portanto, entende-se que são necessárias ações voltadas ao planejamento, diminuição da degradação ambiental e gerenciamento integrado do Reservatório de Itupararanga.

A survey was carried out on the fish species in the Sorocaba. River basin, the main tributary of the left margin of the Tiete River, located in the State of Sao Paulo, Brazil. The species were collected with gill nets. After identification of the specimens, their relative abundance, weight and standard length were determined. Up to the present moment there are not any studies that focus this subject in this hydrographic basin. Fifty-three species, distributed in eighteen families and six orders were collected. Characiformes were represented by twenty-eight species, Siluriformes by seventeen species, the Gymnotiformes by three species, Perciformes and Cyprinodontiformes by two species, and the Synbranchiformes by one species. Among the collected species there were two exotic. The most abundant species were Astyanax fasciatus and Hypostomus ancistroides. In relation to total weight the most representative species were Hoplias malabaricus and Hypostomus ancistroides. Cyprinus carpio, Prochilodus lineatus, Schizodon nasutus and Hoplias malabaricus were the most representative species in relation to average weight. Largest standard length were recorded for Sternopygus macrurus, Steindachnerina insculpta, Eigenmannia aff. virescens and Cyprinus carpio.

In Brazil, rates of urban solid waste generation increase proportionally more than the annual growing of the population. The government, from its federal authority to the municipal spheres, faces increasing challenges for Urban and Environmental management regarding to solid waste in general and, in particular, municipal solid waste. Financial problems added to public health problems that worsen with the serious environmental impacts generated every year. In August 2010 Brazil the PNRS (National Policy on Solid Waste) was approved and sanctioned in which represented a true watershed in the country as a legal framework extremely ambitious and visionary. This work presents the successes and challenges that the municipality of Sorocaba/SP is facing after more than three years of PNRS sanctioned to conduct an Urban and Environmental management suited to the new legal bases towards the subject of solid waste. The results show a large gap between the content proposed by the law and the technical, financial and temporal reality to practical implementation by the municipal government. New legislation and federal incentives, consortiums among the cities, flexible deadlines and environmental education at all levels are certainly some proposals to catalyze processes that aim to solve and overcome the challenges of solid waste

To verify the levels of concentration of some heavy metals in fishes from Sorocaba river (São Paulo, Brazil) and evaluate if this contamination offers health risks to the fishermen, 63 samples of fishes collected from four points along the river were studied for cadmium, lead, chromium, nickel and mercury, with emphasis in this last, since it is the most toxic and most probable as a fish contaminant. Analyzing muscle samples by cold vapor atomic absorption spectrometry it was shown that the fishes are not contaminated. None of the five metals studied were present in prohibitive level and the fishes could be judged secure for human consume. It was also analyzed data from four years of cadmium, lead, chromium, nickel and mercury monitoring made by CETESB, from 1997 to 2000, in water from the main rivers of the State of São Paulo. The study pointed out that the majority of the monitored rivers still present contamination by those metals in a level that requires an improvement of the pollution control actions.
