Live shells, grenades and bombs lie at the bottom of Lake Geneva in Switzerland…  After the WWII, many countrie had a lot of ammunitions. A French diving association, Odysseus 3.1, and the Geneva University believe these munitions represent a real danger to the population and the environment. The Swiss Federal Department of Defence, Civil Protection and Sports (DDPS) stated that these dumped munitions do not release harmful substances and that their recovery is unnecessary. Last November, some divers went to the bottom of the lake (50m deep) to take some samples of mussels. These mussels, an invasive species, will be then analyzed.

It is estimated up to 1,500 tonnes of live ammunition were dumped into the lake between the late 1940s and 1960.
