Resumo: | Accelerated urbanization and disorganized has caused many impacts on the environment, either by modifying the conditions of living and the quality of water resources. The present work aims to characterize the quality and quantity of water and pollutant loads from Botafogo stream, during the dry and rainy, through analysis of quality and quantity, in order to know the behavior of the water quality of the water body and provide impacts of runoff in the water body. During the dry season, nine monitoring were performed in eight sampling points and during the rainy season, only one point was rated 5 rainfall events. Analyses discriminatory (boxplot), cluster and correlation were essential to understand the variations of water quality in dry periods, demonstrating that monitoring in future there is the possibility of reducing the number of sampling points and parameters. It was observed that the parameters COD, BOD5, color, turbidity, coliforms and E.coli showed clear seasonal variation. In the five rain events was evaluated possible to see large fluctuations in concentration during the monitored parameters, especially coliforms and E.coli, suspended solids and turbidity, clearly demonstrating the impact of stormwater drainage on surface water in urban areas, and it is possible to note that many of the parameters showed much higher concentrations than the limits recommended by CONAMA Resolution 357/05, for rivers Class II. It was also found that the BOD5, the COD, turbidity, and total solids best parameters were the first flush indicators. With the results obtained load was observed that the rainfall events are large contributors to the concentration of pollutants in water bodies, since high loads are transported solids and COD. Thus, the results show that the runoff can carry high concentrations of pollutants into the stream Botafogo and this may suffer siltation and eutrophication. Thus, it is demonstrated the urgent need to study the diffuse loads in water bodies, especially in urban areas and assess the measures that can be undertaken in the basin as a preventive, adoption of alternatives for the control and treatment of pollution and mitigation of impacts caused by human actions. |

O presente trabalho teve como objetivo caracterizar a qualidade e a quantidade das águas e as cargas poluidoras do Córrego Botafogo, situado em Goiânia-GO, nos períodos seco e chuvoso por meio de análises de qualidade e quantidade, a fim de conhecer o comportamento da qualidade da água do corpo hídrico e apresentar os impactos do escoamento superficial no corpo hídrico. No período de seca foram realizados nove monitoramentos em oito pontos amostrais e no período de chuva um ponto apenas foi avaliado em 5 eventos chuvosos. As análises discriminatórias (boxplot), de cluster e de correlação foram essenciais para compreender as variações da qualidade da água em períodos secos, demonstrando que em monitoramentos futuros há a possibilidade da diminuição do número de pontos e parâmetros amostrais. Foi possível observar, ainda, que os parâmetros DQO, DBO5, cor, turbidez, coliformes totais e E.coli apresentaram clara variação sazonal. Nos cinco eventos de chuva avaliados foi possível perceber grandes oscilações na concentração dos parâmetros durante os monitorados, em especial coliformes Totais e E.coli, sólidos suspensos totais e turbidez, demonstrando claramente o impacto da drenagem pluvial nas águas superficiais em áreas urbanas, sendo que é possível notar que muitos dos parâmetros avaliados apresentaram concentrações muito superiores aos limites preconizados na Resolução CONAMA 357/05, para rios de Classe II. Verificou-se, ainda, que a DBO5, a DQO, a turbidez e os sólidos totais foram os melhores parâmetros indicadores de first flush. Com os resultados de carga obtidos foi possível perceber que os eventos chuvosos são grandes contribuidores para a concentração de poluentes nos corpos hídricos, uma vez que são transportadas elevadas cargas de sólidos e DQO. Dessa forma, os resultados encontrados apresentam que o escoamento superficial pode transportar elevadas concentrações de poluentes para o Córrego Botafogo e este pode vir a sofrer assoreamento e eutrofização. Assim, demonstra-se a extrema necessidade de estudar as cargas difusas nos corpos hídricos, especialmente em áreas urbanas e avaliar as medidas que possam ser realizadas na bacia como ações preventivas, adoção de alternativas para o controle e tratamento dessa poluição, bem como mitigação dos impactos causados por ações antrópicas.Submitted by Luciana Ferreira (lucgeral@gmail.com) on 2014-10-31T13:15:14Z No. of bitstreams: 3 Dissertação - Aline de Arvelos Salgado - 2013 (1).pdf: 19133020 bytes, checksum: 99f7494b6d5b0c0afb94eb7523a14e81 (MD5) Dissertação - Aline de Arvelos Salgado - 2013(2).pdf: 9872700 bytes, checksum: f92f9ac233f9de3dc5f82ab719021535 (MD5) license_rdf: 23148 bytes, checksum: 9da0b6dfac957114c6a7714714b86306 (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2014-10-31T13:50:45Z (GMT) No. of bitstreams: 3 Dissertação - Aline de Arvelos Salgado - 2013 (1).pdf: 19133020 bytes, checksum: 99f7494b6d5b0c0afb94eb7523a14e81 (MD5) Dissertação - Aline de Arvelos Salgado - 2013(2).pdf: 9872700 bytes, checksum: f92f9ac233f9de3dc5f82ab719021535 (MD5) license_rdf: 23148 bytes, checksum: 9da0b6dfac957114c6a7714714b86306 (MD5)Made available in DSpace on 2014-10-31T13:50:45Z (GMT).

Accelerated urbanization and disorganized has caused many impacts on the environment, either by modifying the conditions of living and the quality of water resources. The present work aims to characterize the quality and quantity of water and pollutant loads from Botafogo stream, during the dry and rainy, through analysis of quality and quantity, in order to know the behavior of the water quality of the water body and provide impacts of runoff in the water body. During the dry season, nine monitoring were performed in eight sampling points and during the rainy season, only one point was rated 5 rainfall events. Analyses discriminatory (boxplot), cluster and correlation were essential to understand the variations of water quality in dry periods, demonstrating that monitoring in future there is the possibility of reducing the number of sampling points and parameters. It was observed that the parameters COD, BOD5, color, turbidity, coliforms and E.coli showed clear seasonal variation. In the five rain events was evaluated possible to see large fluctuations in concentration during the monitored parameters, especially coliforms and E.coli, suspended solids and turbidity, clearly demonstrating the impact of stormwater drainage on surface water in urban areas, and it is possible to note that many of the parameters showed much higher concentrations than the limits recommended by CONAMA Resolution 357/05, for rivers Class II. It was also found that the BOD5, the COD, turbidity, and total solids best parameters were the first flush indicators. With the results obtained load was observed that the rainfall events are large contributors to the concentration of pollutants in water bodies, since high loads are transported solids and COD. Thus, the results show that the runoff can carry high concentrations of pollutants into the stream Botafogo and this may suffer siltation and eutrophication. Thus, it is demonstrated the urgent need to study the diffuse loads in water bodies, especially in urban areas and assess the measures that can be undertaken in the basin as a preventive, adoption of alternatives for the control and treatment of pollution and mitigation of impacts caused by human actions. |
