LAKE COUNTY, Calif. – County officials said Monday that particulate monitors have been set up and are running at Cobb Elementary School, Middletown High School and Coyote Valley Elementary School.

Numbers on those monitors have been good, except for an occasional divergence into moderate air quality during commute times when there are more cars, trucks and buses on the road, the county reported.

Particulate monitors demonstrate attainment or non-attainment of national and state ambient air quality standards.

Because of Lake County’s ongoing exceptional air quality, the impact of the fires and cleanup equipment has had minimal post-fire impact throughout the community, according to Lake County Air Pollution Control Officer Douglas Gearhart.

American Lung Association statistics place Lake County’s air as the cleanest county in the nation for the past three years for annual particulate average concentrations.
