Some places are insanely polluted to the point where you wonder how a whole company could be so braindead and essentially poison themselves.
A place not far from where I live had a chemical plant which just dumped loads of chemicals on a meadow for years. Now there are ground water pumps installed there which need to run 24/7 so that the chemicals don’t contaminate nearby rivers and hence the rest of the country.
When taking samples from the pumped up water you can smell gasoline.

Pro-tip: unplug all the fans and enjoy the silence
