Landfill leachate is an heterogenous percolate composed of hazardous contaminants which formation depend on factors such as age of the landfill, season or waste type. The regulation of the leachate has been required by the European Commission in the Landfill Directive and also other directives have contributed to the reduction of its impact on human health and the environment. Those directives are the Waste Framework, the Water Framework and the Industrial Emissions directives. In practice, little is known on the way those regulations and monitoring are implemented and transposed by the participating countries. To get an insight of the state of art in setting discharge limits, a questionnaire has been used for the representatives of European authorities dealing with landfill leachate management. Very few answers were obtained, thus the Landfill Directive transposing laws of the countries published online were mostly used for the results. In general, the member states don’t derive too far from what is required in terms of frequencies and locations of monitoring. They also, all monitor surface and groundwater. The discharge limits set by the countries are more often case-specific and can show noticeable differences. Germany and France often set the most stringent discharge limits. For every country, discharge limits can be much lower than the concentrations of pollutants found in untreated leachate in the literature thus treatment is necessary to comply with set discharge limits.
