The purpose of this study is to estimate the generation of leachate in a landfill area without the use of a geomembrane liner. The generation of leachate was estimated by the water balance method from 2007 to 2017. Information on underground water quality was obtained through monitoring of historical series in four monitoring wells. The results indicated an average generation of 0.31 L.s-1. The electrical conductivity of the well water monitored changed during the analysed period, mainly in the wells located in the smallest topographic dimensions. These results found that even with the presence of a low permeability clayey soil, the absence of the waterproofing system in this disposal cell, allows the leachate to percolate to the water level of the non-continuous temporary suspended groundwater. This was evident by changes in groundwater quality parameters. Thus, additional studies are recommended, aiming at on-site monitoring of the leachate flow and quality. |
