Last month’s review

Although the spring months usually have the best air quality, this May was unusually dry and calm. The month had the second-highest air pollution levels since we began monitoring last June.

The air monitor in the Chinatown-International District showed 16 “moderate” days and 15 “good” days in May.

Did you know?

Over 20,000 trucks drive along I-5 and I-90 every day through the Chinatown-International District. Diesel engines power most of these trucks and tend to last a long time. Replacing each old truck helps reduce pollution—newer trucks are 50 times cleaner.
