Answer:

For water to become stale, it has to be stagnant(still) like in a pond or lake.

Explanation:

In a river, the water is always flowing. However, if a lot of waste is thrown into the river, it may slow down and water can become stale after some time(this happens especially in cities). For example, the river Yamuna in India.
