Life has been good this summer at 1593 E. Hazelton Ave. in Stockton -- good for the breathing public.

That address is where Stockton's ozone monitor resides. The last time there was an ozone violation here, it was July 9.

Which raises an interesting counterpoint to San Joaquin Valley residents who argue the Bay Area's bad air is contaminating this region.

Stockon would be the first in line for windblown pollution from the Bay Area. So why does it have the healthiest air in the Valley?

Wouldn't it suffer the same fate as San Bernardino County, which is downwind of the Los Angeles metro area? Crestline in San Bernardino has 83 federal violations this year, by far the most in the country.

Stockton has only four this year. Meanwhile, Arvin -- the monitor farthest from the Bay Area in the Valley -- has 67 violations.
