Abstract

The Municipal Solid Waste (MSW) final disposal in landfills corresponds to waste treatment technique that has been practiced the most in the world, however, these sites present potential sources of pollution, requiring constant environmental monitoring. Thus, this study evaluated the relationship between the leachate quality generated at the landfill from Palmeira das Missões (RS) and the local groundwater. For this, it has been carried a historical evaluation of data from the groundwater quality and treated effluent. The data of the groundwater quality parameters has been submitted to descriptive statistics and to Student's t-test. The evaluation of the treated leachate quality revealed that, for the 40 evaluated parameters, 9 had concentrations above the allowed maximum value (AMV) established in the Brazilian resolutions. For groundwater, among the 30 parameters evaluated, 10 are present in concentrations higher than AMV. Statistical analysis revealed that total alkalinity, Pb, OD, BOD5, TDS and TS showed a significant increase in at least one of the analyzes from downstream wells, compared to the upstream well, but only Pb and BOD5 are present in higher concentration than AMV. These results demonstrated that the leachate generated in the landfill is affecting the local groundwater quality. In addition, it’s expected that these results contribute to the improvement of management of the MSW and groundwater resources.
