Cities Skylines How To Clean Up Pollution

There are recyling ordinances and other transh reducing things. Water treatment plants, etc. As far as the ground pollution...I really don't know yet. But this isn't Cities of Tomorrow. I don't think ground scrubbers exist in real life.

Yes, usually the contaminated earth is scraped away and replaced with new soil.
At the moment I'm not sure whether areas stay polluted permanently or do they clear out some time after the active polluting stops (waters clear of course if the stream leads somewhere further).

Pollution appears to fade with time after the source of pollution stops. Im not sure if there is a way to make pollution fade faster.

If you put industry in an area. Let it pollute, and then remove the industry the pollution will disappear(it will take sometime).

I think there's a monument that eliminates pollution altogether.

I don't know if that is true. I have not gotten far enough in a city.

End game monuments are rather op, but you can of course choose not to utilize them. If you do that will open some new possibilities.

Trees will eat up some of the ground pollution and that is as far as I know the only thing that does

this. real companies like BASF use this method, ive seen it first hand. they plant rows of tightly grouped trees and then cut them down and burn them and replant the crop every few years until it meets certain standards so it can then be excavated and replaced.

now sure how it works in game though

From what I have heard, trees doesn't help with soaking pollution.
Currently they just increase land value and reduce noise pollution, but not the ground one.
Above is based on what I've heard in ParadoxInteractive's twitch stream.

How do you identify water polution?

Pollution goes away in due time. De-zone and hit speed to super-fast. It may take a while.

View the water data map (top-left overlay button, the find the water drop icon, top right). It'll be more obvious. Polluted water is darker/brown. Without the data overlay on it's just a deeper blue.

I made a video showing my unmodded city grow from about 16,000 population to over 20,000 WHILE pollution shrunk from 5% to under 1% . It earned me the Earthloving City Acheivment. You can find the video here: https://www.youtube.com/watch?v=Ipkm5-qd1hY
