The inadequate deposition of municipal solid waste in landfills can generate serious consequences for the environment, such as the contamination of surface and groundwater, which can cause serious risks for public health. In this context, the present study aimed to assess the influence of the landfill of Cuiabá city, state of Mato Grosso, Brazil, on the quality of surface water in their surroundings. We analyzed the following parameters: color, alkalinity, pH, turbidity, total dissolved solids (TDS), dissolved oxygen, biochemical oxygen demand (BOD), chemical oxygen demand (COD), phosphorus, nitrate, total coliform and Escherichia coli (E. coli), and metals (Mn, Zn, Pb, Fe, Cd). The Ribeirão of Lipa stream, downstream the outflow of the sewage treatment station of the landfill, was found to have elevated average concentrations of BOD (80mg L-1), color (354mg.Pt-Co.mg L-1), TDS (790 mg L-1), turbidity (101 UNT) and E. coli (1,2x103 NMP 100 mL-1), all of them above the maximum recommended by CONAMA Resolution No. 357/2005 and above the average values measured upstream the treatment station inflow. In one reservoir located nearby the landfill (cell 2), elevated concentrations of BOD (52 mg L-1), Color (226 mg.Pt-Co.mg L-1), SDT (567 mg L-1), Turbidity (162 UNT) and E. coli (2x103 NMP 100 mL-1) were obtained, all of them above the criteria of the Resolution. |
