Emissions Testing

The following table is a summary of source testing performed at Chemours since January 2018. Chemours has contracted with the source testing company Weston Solutions, Inc. for on-site air emissions sampling. Chemours has also contracted with Test America Laboratories, Inc. for the methodology, and laboratory analysis. DAQ staff were present for each source test conducted.
