EPA conducted air sampling in Crossett, Arkansas, between January and June of 2017. The sampling was to determine emission sources of airborne hydrogen sulfide (H2S) in the wastewater treatment system at the Georgia Pacific facility in Crossett, and to evaluate the potential for exposure in the community. This report summarizes the results of the EPA’s hydrogen sulfide air monitoring conducted along Georgia Pacific’s wastewater treatment system and in surrounding Crossett neighborhoods.
