What are the most typical pollutants in water and how are they removed?

Explanation:

There is a wide range of water pollutants usually influenced by humans. Water pollution is a huge problem that affects water ecosystems and their surrounding. Pollutants  can be divided into two major groups, according to their source: point source pollutants (from a single source) and non-point source pollutants (from more different sources).

The only way to limit and control this type of pollution is by government regulations.

This type of pollution can sometimes be removed (digging up the tanker).
