No, because natural means nature and nature does not pollute itself.
There is in nature a Water Cycle that cleans and refreshes all water by evaporating the water from all things... because all things have water in them.
Then, the evaporated water is rained down onto all parts of the Earth and goes through a freezing process in the mountains before thawing into rivers and the ground full of energizing minerals.
Even if the humans pollute as much as they can, the Earth will naturally clean and restore the water to healthy state because the Earth's ecology is stronger and has more stabilizing potential than all the destructive pollution humans can put out there.
