“…Values lower than 6.0 were also determined at spring points P8, P9, P10, P11, P12, P13, P14, P15 and P16 due to the presence of domestic and agricultural waste near the water. The variation coefficient of 12.5 % indicates that the pH in the natural environment of the drainage basin studied is the result of anthropogenic activities, which is in agreement with studies conducted in other drainage basins (Siqueira et al, 2012).…”

The aim of the present study was to determine the environmental characteristics and water quality of a drainage basin impacted by human activities in order to obtain quantitative information for helping the development of environmental management politics of soils, lakes, rivers and water resources. Physicochemical properties and concentrations of metals were determined in different water samples. Dissolved oxygen, pH, turbidity, color, ammonia, phosphorus, phenol, copper, silver, lead, cadmium and iron differed from levels considered acceptable by international regulations, indicating potential environmental pollution due to land occupation and the improper disposal of domestic, industrial and agricultural waste. The leaching of pollutants from the soil to bodies of water was also found. Total dissolved solids, salinity, suspended solids, nitrate, nitrite and zinc levels were lower than the limits imposed by international regulations, but have been increasing over time. Urbanization, industrialization and agricultural processes in drainage basins significantly affect the natural characteristics of the environment, leading to an increase in the concentrations of pollutants and a reduction in the quality of water, plants and soils. As pollutants in drainage basins generally enter into soils, rivers, lakes and ocean, it is necessary to obtain quantitative information about the human impacts in the water quality for developing environmental management politics aiming to preserve the water resources.

“…The trend to acidity was associated with organic matter decay by Blume et al (2010) (6.8-7.3) in the Sinos River basin (Rio Grande do Sul State); Siqueira et al (2012) , 2013 correspond to rainy days, with consequent higher river discharges. In accordance with Crispim et al (2012), another factor that has contributed to increased turbidity in the Campo River, averaging 30 -40 NTU, is the transport of sediments from the overflow of retention boxes filled with eroded soil, from compaction and preparation for sowing, towards the slope, and from rill erosion on roadsides by the poor maintenance of rural roads.…”

“…These values were superior in 16.7%, 41.7%, 83.3% and 91.7% at P1, P2, P3 and P4, respectively, relative to the limit of 1,000 MPN/100 mL set by the Conama Resolution 357/2005 (Brasil, 2005). Likewise, Rocha et al (2006) found values 63% higher than the standard in a rural area; Siqueira et al (2012) recorded values from 200 to 1,300 MPN/100 mL in an urban area. Figure 5 illustrates the temporal variation of dissolved oxygen (DO), from 5.86 to 9.3 mg/L, 7.6 to 9.3 mg/L, 5.8 to 9.4 mg/L and 7.0 to 9.2 mg/L at P1, P2, P3 and P4 sites, respectively, that is, above the limit of 5.0 mg/L of the Conama Resolution 357/2005 for Class 2 (Brasil, 2005).…”

Influence of urban area on the water quality of the Campo River basin, Paraná State, Brazil

et al. 2015

The Campo River basin is located on the third plateau of the Paraná State or trap plateau of Paraná, at the middle portion between the rivers Ivaí and Piquiri, southern Brazil, between the coordinates 23° 53 and 24° 10' South Latitude and 52° 15' and 52° 31' West Longitude. The basin has 384 Km² area, being 247 km 2 in the municipality of Campo Mourão and 137 km 2 in the municipality of Peabiru, in Paraná State. The Campo River is a left bank tributary of the Mourão River, which flows into the Ivaí River. The objective of this study was to monitor water quality in the Km 119 River and the Campo River, tributaries of the Mourão River, with monthly collection of water samples to determine pH, temperature, turbidity, biochemical oxygen demand, dissolved oxygen, fecal coliforms, total solids, total nitrogen, ammoniacal nitrogen, nitrite, nitrate and total phosphorus. The results obtained were compared with the indices established by the environmental legislation and applied in the determination of the Water Quality Index (WQI) used by the Water Institute of Paraná State, regulating environmental agency. Poor water quality in these rivers presents a worrying scenario for the region, since this river is the main source of water supply for the public system. Results of organic matter, fecal coliforms and total phosphorus were higher than the limits established by Resolution CONAMA 357/2005 to river class 2, specially at downstream of the Km 119 River and the Campo River, due to the significant influence of the urban anthropic activity by the lack of tertiary treatment and also rural by the lack of basic sanitation in this area. Results of WQI of Km 119 River and do Campo River indicated that water quality can be classified as average in 71% and good in 29% of the sites evaluated.Keywords: water quality, water resources, Anova, Tukey. Influência da área urbana na qualidade das águas na Bacia do Rio do Campo River, estado do Paraná, Brasil ResumoA Bacia Hidrográfica Rio do Campo está situada no terceiro planalto paranaense, na porção média entre os rios Ivaí e Piquiri, Sul do Brasil, entre as coordenadas 23° 53' e 24°10' de Latitude Sul e 52°15' e 52°31' de Longitude Oeste. A bacia ocupa área de 384 Km 2 , sendo 247 km 2 no município de Campo Mourão e 137 km 2 no município de Peabiru, no estado do Paraná. O Rio do Campo é um afluente da margem esquerda do Rio Mourão, que deságua no Rio Ivaí. O objetivo deste trabalho foi monitorar a qualidade da água do rio Km 119 e rio do Campo, afluentes do Rio Mourão, com coletas mensais de amostras de água para determinação do pH, temperatura, turbidez, demanda bioquímica de oxigênio, oxigênio dissolvido, coliformes fecais, sólidos totais, nitrogênio total, nitrogênio amoniacal, nitrito, nitrato e fósforo total. Os resultados obtidos foram comparados aos limites estabelecidos na legislação ambiental vigente para poluentes na água e aplicados na determinação do Índice de Qualidade das Águas (IQA) usado pelo Instituto das Águas do Paraná, órgão ambiental fiscalizador.

“…As águas da região possuem características ácidas, em virtude da contribuição da área da bacia hidrográfica e da decomposição de material orgânico do ambiente em compostos ácidos, responsáveis pelos baixos valores de pH encontrados também nos solos (SIOLI, 1976;SIQUEIRA et al, 2012). Portanto, em relação ao pH, as águas estariam em desconformidade com a legislação vigente, considerando-se a Resolução Conama nº 357/05, contudo os valores refletem condições naturais da região.…”

Qualidade da água em microbacias hidrográficas com agricultura nos municípios de Santarém e Belterra, Pará

2014

RESUMO -A expansão da fronteira agrícola no Oeste do Pará nas últimas décadas tem alterado a paisagem, antes ocupada por florestas ou agricultura familiar, provocando alterações ambientais com impacto nos recursos hídricos. O trabalho avaliou a qualidade da água de 24 microbacias hidrográficas, sob diferentes usos de solo: área natural/referência (Flona Tapajós), agricultura tradicional (PA-Moju) e agriculturas mecanizadas recentes e antigas de soja (Rodovias Curuá-Una e BR-163, respectivamente), com base na Resolução Conama n° 357/05, em Santarém e Belterra, no Pará. As coletas ocorreram em outubro/11 e abril/12. Parâmetros analisados: pH, cor, turbidez, TDS, OD, DBO, nitrato, nitrito, nitrogênio amoniacal, fósforo total, clorofila-a e coliformes termotolerantes. Confrontando os resultados com os da Resolução, constatou-se no período seco que seis microbacias da Flona Tapajós e uma do PA-Moju apresentaram concentrações abaixo dos limites permissíveis para OD. Apenas uma microbacia (BR-163) apresentou pH no intervalo aceitável, e todas as microbacias do PA-Moju superaram o limite estabelecido para clorofila-a. A cor apresentou desconformidade em quatro microbacias da Curuá-Una, durante o período chuvoso. As atividades antrópicas estão causando assoreamento e aporte de compostos e nutrientes aos recursos hídricos, promovendo a sua degradação. A Resolução n° 357/05 necessita de adequações para a região Amazônica, visto que alguns parâmetros que apresentaram valores em desconformidade com a legislação refletem condições naturais da região.Palavras-chave: Recursos hídricos; Uso do solo; Limnologia.
