Results for Aidenn Lair Well

*This well currently has GAC treatment. Please note that the results below (up to and including 7/18/2018) were prior to GAC treatment being installed.

All monthly testing results after GAC treatment was installed have been non-detect with an exception on 10/29/2021 where PFOA was detected slightly above the detection limit (3.2).  Subsequent follow-up samples were once again non-detect.

In January 2022, the most recent PFOA samples detected slightly above the detection limit (3.0 on 1/3/22 and 3.1 on 1/20/22) and the well was taken out of service. A carbon exchange was performed and the well was back in service April 2022. The latest non-detect result was tested on 8/15/2022.
