Sulfur Dioxide (SO2) Monitoring

DHEC has developed an ambient (outdoor) air quality monitoring network for sulfur dioxide and other pollutants to:

  • measure maximum expected concentrations
  • measure concentrations in areas where people live, work and play,
  • provide background information in rural areas,
  • help determine the impacts of sulfur dioxide emissions from specific sources, and
  • monitor interstate and intrastate transport of pollutants.

In 2011, there were 7 SO2 monitors strategically located in 5 counties throughout the state. DHEC chose the location for each monitor in accordance with EPA monitor-siting requirements found in the Code of Federal Regulations Title 40, Part 58, Appendix E.
