What is the term for gas in neighbourhood coming from the sewage treatment plant?

Very strong overwhelming smell the word gas is part of the term.

The term is gas or effluent. The term for the neighborhood—ghetto, wrong side of the tracks, etc. There are no sewage plants near the rich folks.

We say sewer gas.

Noxious gas or noxious odor

Methane sewer gas?

Stench.

Flow.

Safety hazard

Many sewer treatment plants create quite a bit of methane. Bigger ones actually capture the gas and utilize it for other things.

@LuckyGuy‘s “sewer gas” and @stanleybmanly‘s “effluent” are in Wikipedia,
https://en.wikipedia.org/wiki/Sewer_gas But “effluent” only appears at the very bottom under “Sewerage”. @SQUEEKY2‘s “methane sewer gas” doesn’t appear anywhere, I don’t understand.
And I used Ctrl F to find all three terms here:https://www.dec.ny.gov/chemical/90323.html with None are there. I don’t understand.
