The present study was concerned with checking the water quality, the recovery of the riparian vegetation and vegetation around the springhead of stream Bandeirantes, such as the inadequate disposal of waste along this stream, which is located in Rio Claro, SP, in the period from March to July of 2010. Aiming to propose mitigation measures to reverse the degradation processes and develop activities to help a better awareness of the population directly related to this water resource. The water quality was analyzed by performing monthly sampling in three different points along the stream. The first point of sampling is in the spring of the stream, the second at the region called estradão and the third near its mouth, when it flows into the Ribeirão Claro, a tributary of the right bank of the Corumbataí river. It was calculated from the Water Quality Index (WQI) developed by Cetesb. The results were compared with current law. The riparian vegetation, which is responsible for the protection of rivers and streams, was observed and examined during the field work. The results indicated the stream as class 2 and the WQI has been classified, in the most of the analysis, such as a water of good quality. However, some parameters showed a worrying situation and highlighted the current situation, with waste deposits, furniture and animal waste into the pit of the stream studied

The competitiveness among global markets, the constant need for reducing manufacturing costs and also the growing environmental commitments are fueling the development of techniques for recovery residual parts generated by industrial processes. Among the various areas of a company, we highlight those that involve the processing of raw materials derived from oil, such as polymers (resins), which may take centuries to decompose in the environment and also present as a economic and environmentally strategic point. Thus, this study would examine the recovery of waste polypropylene, from the injection process of a major multinational in the field of home appliances through the recycling by a process comprising the milling, extrusion and chipping of waste material. Easy to deploy, this proposal aims to reduce levels negligible disposal (scrap) of these residues as well as the reintegration of the production process into pieces no visual and no structural importance, aimed at cutting costs and reducing environmental impacts caused. After the survey data in kilograms of waste material generated in a given period of time, and the study of changes in material properties, it would enable the reuse steadily in the injection process

The treatment of domestic and industrial effluents through Wastewater Treatment Plants (WTPs) generates a residue termed sewage sludge, rich in organic matter, high-volume, occasionally containing pathogens and heavy metals. The sludge generation can minimize the benefits brought by the treatment of sewage, because this residue does not always receive appropriate treatment before final disposal. The disposal is another problem related to sludge. Landfills generally does not have physical space and alternatives such as the use in agriculture requires an intense treatment that could be in many cases operational or economic unfeasible. The objective of this work is the theoretical research about the processes of stabilization of the sludge by anaerobic digestion and the methanogenic activity during the process. Through analysis of each step and contemplating each relevant factor in anaerobic digestion process in order to optimize them, we proposed a theoretical model of reactors capable of stabilize the sludge, reduce its volume and eliminate pathogens. The obtained configuration consists of two anaerobic reactors connected in series. The first one operates in the range mesophilic temperature (35 ° C) and has higher hydraulic retention time (25 days) working primarily in the stabilization of organic matter present in the sludge and producing biogas, whereas the second one operates in the thermophilic range (55 ° C) in order to eliminate pathogens, and to reduce the volume. The hydraulic retention time in the second reactor is lower (10 days). Both mesophilic and thermophilic processes were efficient in what was proposed, promoting the stabilization of organic matter present in the sludge and significant reduction of pathogens. As a final step with the sludge previously digested, it is indicated a final dehydration... (Complete abstract click electronic access below)

A ocupação inconsequente do território e a aplicação de técnicas agropastoris altamente degradantes ao meio ambiente, no Estado de São Paulo, culminaram em uma diminuição da cobertura vegetal nativa preservada de apenas 14% da cobertura original. Nesse cenário, o Novo Código Florestal, de 1964, regulamentava a proteção das chamadas Áreas de Preservação Permanente e a aplicação da área de Reserva Legal, que consistia em uma porcentagem da área total da propriedade rural destinada à preservação para a manutenção da biodiversidade local. Com a função de guiar as propostas de recuperação das áreas degradadas e de preservação dos remanescentes nativos, um Programa de Adequação Ambiental foi desenvolvido no presente estudo. Seu objetivo é adequar uma pequena propriedade rural, localizada no município de São Carlos – SP, às leis ambientais, com a finalidade de torná-la o mais ecologicamente sustentável possível. Com o auxilio de imagens de satélite disponíveis gratuitamente na internet e programas de SIG (ArcGis, Stitch Maps), o Programa de Adequação Ambiental da Estância 4R avaliou os usos e ocupações da propriedade, indicando que mais da metade da propriedade (35 ha) são destinados à criação de gado de corte e quase todo o restante (20 ha) está arrendado para o cultivo de cana-de-açúcar, e sugeriu propostas de restauração da área de Reserva Legal, cuja área deve ser de 12 ha, bem como sua localização, ao sul da propriedade. Como ação de restauração, foi proposto o consórcio de espécies arbóreas nativas com linhas de plantio de café de sombra, em um sistema de plantio conhecido como Agroflorestal

Currently, the dam of Salto Grande is very degraded. Water quality is seriously amended, and lack of riparian vegetation, as well as the advance of feed crops and land occupation in areas that should be permanently preserved, only complicate this situation. The permanent preservation area is essential for the water sources protection, soil erosion control and consequent watercourse sedimentation. Through aerial photography, using GIS techniques, it was able to identify the outwards bounds of the dam, to demarcate the permanent preservation areas and generate maps for land use. With this data, in addition to studies and ideas of reforestation in different environments, the development of a plan for restoration of degraded areas surrounding the dam is easier to be done. This study confirmed that about 72% of land use in permanent preservation areas is not in accordance with specific laws, making necessary its recovering.

Oil spills cause serious damage to the cost life and environments. Those impacts affect ecologic and socio-economic resources (like fishing and tourism). Within this background, response actions have two main objectives: the contaminant removal, with the less additional impacts, and enhance environment restoration in order to make this process complete in the shortest time possible. The present work proposes to contribute for the emergency environmental management in cases of oil spills by systematization of relevant information for oil spill environmental sensitivity maps. The next stage was to insert all these data on a geographic database, which allows data access by web. Beside that, this work aimed to recommend suitable clean-up techniques for the ecosystems located on the study area, composed by the municipalities: Praia Grande, Mongaguá, Itanhaém and Peruíbe, belonging to Baixada Santista and Iguape, Cananéia and Ilha Comprida, south cost of São Paulo state. This area is situated between two important Brazilian ports: Santos and Paranaguá, and that make it under considerable accident risks. The results were all data inserted on the geodatabase and available to user recover the information by web consulting. With that, this work wishes to contribute to individual emergencial planning of the region.

The lack of proper planning in intervention works of runoff water on rural properties and rural public roads leads to economic damage and loss of environmental quality. The impact of the action without technical base is soil erosion, siltation of water sources, loss of the quality and availability of water, invalidating areas for cultivation and livestock. The conservation of headwaters requires beyond regeneration of the environmental characteristics the repair and management of the degraded watercourse in order to control erosion. This graduate work in Environmental Engineering from Universidade Estadual Paulista Julio de Mesquita Filho - UNESP Presidente Prudente proposes a headwater recuperation and management in rural area of Álvares Machado municipality, São Paulo State, through the method of deep drainage applied to the case of a rural road near the outcrop of water. This technique consists in the installation of draining structures in sub-areas of the road surface, or sub-gutter and/or in the platform border in order to conduct the underground flow of water and reduce the loss of sediment in water flow. Therefore, was performed a historic study of use and occupation of land in the municipality of Álvares Machado, portraying transformations of the landscape caused by human action. Geology, geomorphology, pedology and hydrogeology data were collected from the study area in order to establish the conditions that led into the current situation of degradation and formulate an effective intervention strategy for civil works

Este trabalho objetivou analisar a qualidade da água de três córregos tributários do rio Bauru, levando em conta a poluição causada por produtos orgânicos e industriais que vinham sendo descartados nos mesmos e as eventuais melhorias conseqüentes das medidas paliativas assumidas pelo DAE-Bauru, mediante a instalação de interceptores-coletores de águas residuárias ao longo Daqueles corpos de água, até que a Estação de Tratamento de Esgotos do município seja construída e se dê início ao seu funcionamento. O monitoramento destes corpos de água durante o período de estiagem e de cheias proposto nesta pesquisa, incluiu investigações sobre as variáveis químicas e físicas de amostras das águas, obtidas mensalmente em 7 pontos de coleta, localizados a montante e a jusante dos pontos de instalação dos emissários, ao longo dos córregos. As amostras de água foram posteriormente analisadas para fossem obtidas informações sobre a eficácia da instalação dos interceptores com relação ao processo de recuperação da saúde dos corpos aquáticos em questão. Os resultados obtidos mostraram que, de um modo geral, as águas de todos os sistemas estudados ainda sofrem impactos, até porque ainda há aquelas que recebem o esgoto descartado “in natura”. No entanto, como ja era esperado, nos pontos de coleta localizados em segmentos dos córregos nos quais os emissários já foram instalados, o impacto ambiental é menor. Mediante a comparação dos resultados obtidos das análises das características físicas e químicas das águas dos sistemas estudados realizadas durante esta investigação com aqueles obtidos nos mesmos corpos de água, em 2007, pudemos observar melhorias da água em alguns dos pontos de coleta

When handling soil conservation practices isn’t applied correctly, they cause problems at the level of structure, cohesion and fertility in soils and lack of water availability. In the case of this monograph, conducted in a rural property located at Álvares Machado City, identified that most areas are intended for use activities of beef cattle and dairy and subsistence agriculture, which historically addition to withdraw native flora, resulting in problems such as compaction and increase soil exposure to climatic agents, generating a serious frame of erosion problems. In the case of water from rainfall, the soil exposed, causes the “splash” effect and therefore when it becomes runoff carries the spalled particles mainly for low land areas. Without the vegetation, especially trees or shrubs species, the velocity of runoff increases, initiating the appearance of furrows, which consequently may become a kind of ravine erosion and gully, which makes invalid any area in your surroundings...
