The major waste management efforts undertaken in the last decade (particularly the plant built on the small island of Psytalia) have greatly improved water quality in the Saronic Gulf, and the coastal waters of Athens are now accessible again to swimmers. In January 2007, Athens faced a waste management problem when its landfill near Ano Liosia, an Athenian suburb, reached capacity. The crisis eased by mid-January when authorities began taking the garbage to a temporary landfill.
