*This well currently has GAC treatment.
All monthly testing results after GAC treatment was installed have been non-detect with an exception on 10/29/21 where PFOA was detected slightly above the detection limit (3.2). Subsequent follow-up samples were once again non-detect.
In February 2024, PFOA samples were detected slightly above the detection limit; the well was taken out of service so a carbon exchange could be performed.
