LEON-GOMEZ, Héctor de et al. Impact of leachate generated in the municipal landfill of Linares (Nuevo León ) on the quality of surface water and groundwater. Rev. mex. cienc. geol [online]. 2015, vol.32, n.3, pp.514-526. ISSN 2007-2902.

This research deals with the quality of natural waters affected by pollution from leachate generated in the Municipal Landfill of Linares, Nuevo Leon, Mexico. The Municipal Landfill of Linares has more than 17 years of service and receives more than 50 ton/day of municipal solid waste. Geological (geological structural profiles), hydrogeological (piezometric cards) and hydrogeochemical (water quality classification and determination of pollutants) methods were applied to identify external agents to the environment. A negative impact on the quality of surface water (dam El Cinco) and groundwater (wells) in accordance with national and international environmental standards (NOM, WHO, US EPA) were identified. The results reveal deficiencies in the management and final disposal of municipal solid waste (torn geomembrane) and null leachate management (oversaturation of the landfill). In particular, high concentrations of NO3, Pb, Mn and Fe in groundwater and surface runoff were identifying, which generate a significant contamination of soil and water; aspect very important if people in the region consume contaminated water from groundwater wells, that can cause harmful health effects.

Keywords : Leachat; municipal solid waste; landfil;, groundwater, Linares; Mexico.
