Resumo: dc.description.abstractThe suinicultural activity in southern Brazil generates jobs, has a positive economic impact, but generates a large amount of waste, which is usually applied in agricultural areas as a form of disposal and fertilization. The waste has in the composition pollutants and/or contaminants of the environment, which can cause degradation of water bodies. The study aimed to evaluate the contents of dissolved oxygen (OD), electrical conductivity (EC), total dissolved solids (TDS) and cationic characterization, in waters in a hydrographic basin of southern Santa Catarina, with intense swine activity. The present study was developed from July/2015 to June/2016, in the municipality of Braço do Norte, Santa Catarina. Water samples were collected from four agricultural farms and three points of the Coruja River. Soil samples were also collected at the properties. The contents of dissolved oxygen (OD), electrical conductivity (EC), total dissolved solids (SDT) and cationic characterization (Ca, Mg and K) were evaluated in the water samples. The available levels of ca, mg and exchangeable K were evaluated in soil samples. The OD values in waters, in general, were lower than the minimum limit value established by the legislation, indicating high organic load that may be being conducted from adjacent agricultural areas to surface waters. For dissolved EC, SDT, Ca, Mg and K, there is no delimitation of maximum levels in CONAMA Resolution No. 357/2005. Therefore, not indicating contamination and / or pollution by these elements in water or soil.pt_BR
