The Association for the Protection of the Lake of Geneva (in French “Association pour la Sauvegarde du Léman” or ASL) is a French-Swiss association. Its purpose is to preserve the water’s quality in the Lake of Geneva’s basin, i.e. rivers and waterways flowing into the lake. This association spreads the information through campaigns, research and hard work in the field, e.g. the «Clean River Action» and the «Clean Lake Action».

The ASL is a non-profit association and a recognized apolitical, scientific, public service with an actual community of 5,000 members. The aims of the ASL are to create an awareness among residents of the area, to identify the problems involved, and work toward their resolution.

The «Clean Rivers Action» («Opération Rivières Propres» or ORP) and the «Clean Lake Action»  («Opération Léman Rives Propres» or OLRP) are about checking 5,000 km (about 3,100 miles) of waterways flowing into the Lake of Geneva. Uncontrolled polluting sources and
litter are poisoning our water. These must be analysed, measured and assessed. For more detail, check our actions pages.

ASL undertakes the coordination, conclusion, publication and distribution of results to communal, cantonal and federal authorities, asking them to take all the necessary measures to rapidly restore water safety.

Furthermore ASL is convinced that every contribution made today for a healthier environment helps. Indeed a healthy environment can only be the most precious legacy we can leave to tomorrow’s generations. We are therefore grateful for any encouragement. Join us!

Last but not least, and as you have probably noticed, there are only a few pages in English. If you wish to get even more involved in this association, your help for translation (French to English) would be deeply appreciated. Kindly contact us.
