Air Quality

Clean air is important for your health. Many activities contribute to outdoor pollution every day, including cars and trucks, grilling in restaurants and building heating. Others, like wildfires, building fires, fireworks and weather events can result in occasional high pollution days. Indoor air pollution comes from smoking, cooking, household cleaning products, poor ventilation and other building maintenance problems.

While poor air quality affects us all, older adults, children and people with heart and lung conditions are most at risk.

City, State and Federal agencies measure what is in our air and study how pollution can lead to health problems.
