Efectos ambientales en el aire, agua y suelo de los residuos sólidos urbanos de un relleno sanitario del Estado de México.

In Mexico, municipalities deposit their urban solid waste (USW) in uncontrolled sites or sanitary landfills (SL); therefore, there is a need to improve their conditions and know the existing impact on air, water and soil. The elemental characterization of the leachate, soil and water was carried out, a sample of well water near the SL (1.5 km) and leachate was characterized physicochemically and microbiologically. Air quality and weather conditions were analyzed. The leachate has a high organic load, nitrogenous matter and chlorides, and a low BOD5/COD biodegradability index of 0. The concentration of air pollutants is within the permissible limits because it is an open area and the wind speed favors their dispersion. In the soil there are concentrations of retained metals that prevent their migration to groundwater. [ABSTRACT FROM AUTHOR]
