WHATCOM COUNTY, WA (MyBellinghamNow.com) – Whatcom County’s air quality has received mixed ratings over the past few years amid summer smoke from wildfires.

That’s according to the American Lung Association’s annual “State of the Air” report using data from 2021 through 2023.

The report gave the county an “A” grade for ground-level ozone pollution, ranking it among the cleanest in the country. But, similar to many other counties throughout the state, Whatcom received a “D” grade for particle pollution.

The Northwest Clean Air Agency attributes that grade to high levels of wildfire smoke in the three summers covered by the report.

The agency still says people who live and work in the county are generally exposed to good air quality.
