Air Monitoring Update

Air monitoring results are regularly published on this website as well as the GA EPD site.

April 2021 Update:

As of March 2021, when the air monitoring reports were last updated, average concentrations of EtO in Covington’s ambient air samples were 0.290 μg/m³. Results continue to be consistent with typical background levels found by the U.S. EPA in their nationwide study. (between 0.2 μg/m³ to 0.4 μg/m³). People who work in, live near, or drive by BD facilities in these communities every day are exposed to very typical, low levels of EtO.

In addition, the Georgia EPD has air monitoring stations in other parts of the region. The data show that average concentrations of EtO in ambient air samples in Covington, Ga. are generally lower than the concentrations s observed at EPD’s background monitoring station in South DeKalb as well as those in the rural General Coffee State Park. The data also show that average concentrations across the greater Atlanta area are about the same in areas where EtO sterilization facilities operate and areas where they do not.

How Does EtO in Covington Compare to The U.S.?

EtO concentrations measured in ambient air samples in Covington by the Georgia EPD and BD are consistent with the average background concentrations the EPA found nationwide in urban and rural areas that are not near sterilization facilities.
