“I didn’t know ozone was still a thing.”
I haven’t heard a peep about ground-level ozone emissions in 20, maybe 30 years. All of the sudden it pops in 2022 up as the raison d’être to BAN natural gas water heaters? What the hell?
It is ground level ozone (O3)...has been a problem for 40-50 years on hot days. Today’s forecast for the area of FR HQ (Fresno) was 78 ppb (Stage 3 of 6) actually topped out at 86 ppb today.

(A good reason to not purchase an “Eden Pure” air “purifier”/ozone generator that is advertised heavily on radio lately).
