Resumo: | ABSTRACT: This research aims to evaluate the water quality of the Vicente Pires basin, a tributary of the Paranoá Lake, with the use of polutographs and hydrographs, through flood and dry events of dissolved (DS), suspended (SS) and total solids (TS) and turbidity. The monitoring happened in the VP Stream outfall with water level measurement, to determine the flow, simultaneously collecting water samples for analysis of pollutant concentrations. Five events were analyzed, from 2018 to 2019, with flow from 0.88 m³/s to 72.17 m³/s, DS concentrations from 13 to 4,445 mg/L, SS from 0 to 5,164 mg / L, and TS from 24 to 7,583 mg/L and turbidity from 6.2 to 9,522 NTU. It is clear from the polutographs that the concentration of solids and turbidity in the VP Stream are related to the flow, with flood events being those with the highest concentrations. Therefore, this fact is related to runoff, which generates large flows, washing off the soil surfaces, and carrying what is deposited, such as landfills of major works that occurred in the drainage basin. In addition to diffuse pollution, large flows from surface runoff reach the stream causing erosion on the banks, further aggravating the sediment transport problem. In fact, in order to guarantee the maintenance of the VP Stream, it is necessary to control the sediment input from diffuse pollution, requiring the adoption of compensatory measures in urban drainage since its construction. KEYWORDS: Diffuse Pollution, Monitoring, Runoff. |

O monitoramento ocorreu no exutório do Córrego VP com a medição de nível da água, para determinação da vazão, simultaneamente a coleta de amostras de águas para análise das concentrações dos poluentes. Foram analisados 5 eventos, de 2018 a 2019, com vazões de 0,88 m³/s até 72,17 m³/s, concentrações de SD de 13 a 4.445 mg/L, SS de 0 a 5.164mg/L, e ST de 24 a 7.583 mg/L e turbidez de 6,2 a 9.522 NTU. Percebe-se, quanto aos polutogramas, que as concentrações dos sólidos e da turbidez no Córrego VP estão relacionadas com a vazão, sendo os eventos de cheia os de maiores concentrações. Portanto, este fato é relacionado com o escoamento superficial, que geram grandes vazões, lavando as superfícies dos solos, e carreando o que está depositado, como aterros das grandes obras ocorridas na bacia de drenagem. Além da poluição difusa, as grandes vazões advindas do escoamento superficial atingem o córrego causando as erosões nas margens, agravando ainda mais o problema de transporte de sedimentos. De fato, para a garantia da manutenção do Córrego VP é necessário o controle do aporte de sedimentos advindo da poluição difusa, sendo necessário a adoção de medidas compensatórias na drenagem urbana desde a sua construção.
