We promote and protect the health of the public and the environment.
Due to the health effects of ground-level ozone, DHEC
provides the service of forecasting ozone concentrations to warn the public of unhealthy air and to encourage people
to avoid exposure to unhealthy air and voluntarily reduce emissions. DHEC may declare an Ozone Action Day when ozone levels are
forecast to reach unhealthy levels. On ozone action days, you can take simple steps to reduce the pollution that
results in the formation of ground-level ozone.
This webpage is updated each day of the Ground-level Ozone Forecasting Season (April 1 - September 30) by 4:00 p.m. EDT for the following day.
