Is all the water on Earth polluted?
No, since water can be purified, there is plenty of pure water on Earth. Air
pollution circles the entire globe so every major body of surface water has
been contaminated to some degree, including the polar ice caps. Underground
water is usually pure since it has been filtered through the ground and has
not been exposed to air pollution. There are some problems with ground water
pollution in certain agricultural and industrial areas, but polluted water can
usually be purified by filtering out the bad stuff.
