Caracterização ambiental do ribeirão Piampum, Ijaci, Minas Gerais

Abstract

The new legal framework for basic sanitation was sanctioned with goals of at least 90% of the population with water treatment and sewage collection. However, this situation is not consistent with the Brazilian municipalities that dispose their waste in bodies of water. Given this panorama, the present research aims to make an environmental characterization of the Piampum stream, analyzing physical and chemical parameters of the water, as well as biological parameters, using benthic macroinvertebrates. The collections were carried out in six locations from upstream to downstream. The physical-chemical parameters were: pH; conductivity; toughness; chlorides, turbidity; total solids and dissolved oxygen. The benthic macroinvertebrates were collected with a “Surber” sampler. It is concluded that the physical and chemical parameters need to be monitored for being changed. And the benthic macroinvertebrates have changed wealth, abundance and composition as waste dumping increases along the watercourse.
