In France, each city has either its river or a part of a river. For example, Paris has la Seine, and Tours has the Loire, which is one of the foremost exciting factors about Tours. It is hard to believe that the water from a river is drinkable without the necessary steps to remove bacteria, germs, dirt, etc… Although the Loire is known for having a drinkable river, not all the bacteria are removed. However, Tours has a stringent law heavily enforced regarding polluting the river.
