We promote and protect the health of the public and the environment.
Monitoring the air we breathe is one of the most important responsibilities of the Bureau of Air Quality (BAQ). The data we collect is used by the U.S Environmental Protection Agency, individuals within DHEC, and the general public. A history of South Carolina's Ambient Air Quality Data Summaries and Criteria Pollutant Daily Maxima are presented below.
If you have any questions, please contact a BAQ staff member.
