Abstract

The aim of this paper is to analyze two urban landfills and their effects on groundwater in Brazilian savanna. Leachates two Brazilian sanitary landfills and quality of ground water in landfill areas were studied. Landfill sites were located in Goiânia (Goiânia Sanitary Landfill) and Brasília (Joquey Club Sanitary Landfill). In general, the effects of landfill activity appeared most clearly as high concetrations of organic matter (COD and TOC), manganese, iron, ammonium and chloride and as high conductivity. However, low oxygen level can lead to high concentrations of manganese and iron also in unpolluted groundwater, depending on the soil type of the area. Cyanides, which have relatively high mobility in soil, were found in groundwater samples. Concentrations of chlorophenols in leachates were is some cases quite high, but in groundwater samples concentrations were low.
