The large accumulations of putrescible materials which comprise a modern landfill have potential to generate quantities of highly‐polluting leachate as they decompose anaerobically over many years. Operators must control and manage such leachates if severe environmental impacts are to be avoided. Progress has been made in the development of simple, automatic, robust and reliable treatment systems as full‐scale plants have been installed at UK landfills during the last decade, with the assistance of Department of the Environment funding to allow detailed monitoring of particular schemes. This paper describes the results from a site where such a plant was installed in 1985 to overcome a particularly difficult leachate problem, where high ammonia concentrations had posed a threat to local watercourses. More than two and a half years' results of detailed operational data are presented, and particular emphasis is given to the reduction of ammonia concentrations to low values.
