1. Assessing the sources of high fecal coliform levels at an urban tropical beach
Recreational water quality is commonly assessed by microbial indicators such as fecal coliforms. Maceió is the capital of Alagoas state, located in tropical northeastern Brazil. Its beaches are considered as the most beautiful urban beaches in the country. Jatiúca Beach in Maceió was found to be unsuitable for bathing continuously during the year of 2011.

2. Caracterização ambiental e estimativa da produção de cargas difusas da área de drenagem da represa de Itupararanga, SP / Environmental characterization and estimative of diffuse pollution of Itupararanga watershed, SP
The use of satellite images has improved the study of the land use dynamics. Land cover mapping have become fundamental tools in the assessment of landscape changes caused by human action and its influence on regional and urban planning. Computation tools such as Geographic Information Systems and hydrological models have supported these findings. The hydrol

3. Transporte de nutrientes e bactÃrias por escoamento superficial devido a aplicaÃÃo de Ãgua residuÃria da suinocultura no solo
The swine activity is a characteristic of the south region of Brazil, and in the State of Parana it has been of outstanding economical and social importance. However, this activity presents low environmental quality due to the generation of great volumes of liquid residues with elevated pollutant power due to his physical, chemical and microbiological charac

4. Metodologia para avaliação do potencial de produção de poluição difusa: estudo de caso da bacia do Rio Jundiaí. / Methodology for assessment of river pollution originated from non-point sources: case of Jundiai River basin.
As cargas de poluição de origem pontual e difusa são responsáveis pela degradação da qualidade da água de rios, córregos e lagos. A pouca disponibilidade de dados para a aplicação de modelos sofisticados é um obstáculo para a avaliação da poluição difusa no Brasil. Tiveram-se como principais objetivos a realização de pesquisa e aplicação

5. Identificação dos sistemas de produção agropecuária do arenito caiuá sujeitos a erosão utilizando o modelo AGNPS
The series of impacts due to the inadequate exploitation of natural resources by agriculture produces, among other effects, the erosion of the soils, which causes serious damage to the society through the reduction of its productive capacity and the continuous contamination of surface water with sediments, material and organic matter, chemical products and n

6. Influência do lodo de ETE na massa para fabricação de cerâmica vermelha
The WTP produce many kinds of residue on your treatment stages, but the sludge is the more problematic from the final disposition point view. The actual rate of residue production deriving from technological evolution and the crescent population needs prevents the subtle equilibrium generation between consumption and recycling/reuse, creating problems of pol

7. DiagnÃstico geoquÃmico e geocronologia do sistema estuarino-lagunar do roteiro Alagoas
The estuarine lagoon system of the Roteiro is located in the central coast of Alagoas, showing the largest continuous area of preserved mangroves of the State of Alagoas. This ecosystem has been heavily impacted by various anthropogenic activities such as urbanization, the cultivation of oysters, the gas production, the manufacture of cement and the cultivat

8. Diretrizes para implantação de sistemas de reúso de água em condomínios residenciais baseadas no método APPCC - análise de perigos e pontos críticos de controle: estudo de caso Residencial Valville I. / Guidelines for water reuse system in residential condominiums based on HACCP method: Valville I case study.
Water is about to become a scarce resource, due to the population growth that increases the demand or even because of the offer reduction, especially due to water springs´ pollution. One of the alternatives to face this problem is the Water Reuse technique, an important instrument to water management and owner of high technologies to its properly utilizatio

9. Técnica de gerenciamento da qualidade hídrica superficial baseada na otimização multiobjetivo / A technic of surface water quality management based on the multiobjective optimization
Problems of water quality management involve many aspirations of the users engaged, those that use water for wastewater dilution or for their consumption. Therefore, it is uncommon that decision-making mathematical models used are expressed in terms of a single objective, like the maximization of economic efficiency. Using a particular water system, one shou

10. Avaliação do risco de contaminação de mananciais hídricos para o abastecimento: o caso da bacia da barragem do descoberto
In catchments where the threat of impairment is due to non-point pollution, identifying the critical areas that contribute a large amount of pollutants is of paramount importance for the sustainable development of the watershed. Often resources for catchments management are poor and there is no way to establish a comprehensive monitoring system or to calibra

11. Mercury occorrence at the Iguaçu River Basin, State of Parana, Brasil / Ocorrencia de mercurio na Bacia do Rio Iguaçu, Estado do Parana, Brasil
Mercury contents in rocks, soil and stream sediment were determined to investigate the origin of the geochemical anomaly found in sediments of the Iguaçu River, as indicated in previous studies of a regional geochemistry survey. Except for its headwaters in the Curitiba area, with Precambrian basement rocks and Pleistocenic sediments of the Curitiba Basin,

12. Study of optimized localization of equipments for contamination detection in water distribution networks / Estudo da localização otimizada de equipamentos para detecção de contaminação em redes de distribuição de água
The water supply quality is very important to the healthy of urban nucleus populations around the world. This is the reason why many researches focus on such theme. Besides this, recent terrorist attacks occurred in USA and Europe, have incited the old apprehension related to possible deliberate intrusions of contaminants into the water supply networks, maki
