The water may be safe to drink in Chalons, France

Why? The water is chlorinated, so local people can drink water from the tap with no problems. However, there are some small strains of local E. coli present in the water, which may cause diarrhea to new visitors. While your body develops immunity, bottled water is recommended for the first few weeks.
