Landfills are the most popular means of waste disposal in Poland. Unfortunately, most of them leak and pollute surface waters with harmful underground leachate. Although there are many methods of purification of landfill leachate, they are generally complex and expensive. One simpler and less expensive method involves the use of turfgrasses and the accumulation of toxic elements from landfill leachate in their biomass. They are also used for their soil-forming, anti-erosive, and decorative properties. In an experiment at the municipal waste landfill in Wrocław Swojczyce, we determined the accumulation of heavy metals from leachate by five species of sown grass cultivars. The best cultivars with regard to heavy metal accumulation were the Festuca ovina cultivar Noni and Lolium perenne cultivar Inka.
