Samples were taken at 65 bathing spots between May and June from lakes in Central Switzerland, including Lake Lucerne, Lake Zug, Lake Zurich and smaller lakes in the region, the Lake Lucerne Supervisory Commission announced on Tuesday.
The water samples were analysed for intestinal bacteria. The tests were carried out by the Laboratory of the Original Cantons and the Food Control and Consumer Protection Agency. All sampling points achieved “good to excellent” water quality, according to the authorities. No recommendations or restrictions had to be issued for bathers.
