Question

Why is the water upstream so muddy (undrinkable) but the water downstream is so clear that you can drink?

Answer 1

There is rocks near the end and that helps it make it into drinkable water

Answer 2

It is a process call self-purification

Step-by-step explanation:

The reason muddy water becomes so clear and looks almost drinkable at the end of a stream is because of a process that is called self-purification. This is a natural process of purifying, as the ability of a body of water to rid itself of pollutants.
