POUGHQUAG – Due to the chemical PFOA exceeding the maximum contaminant level (MCL) in the Dalton Farms Water System in June 2021, The Dutchess County Water and Wastewater Authority has been coordinating with the county health department and monitoring PFOS/PFOA levels in the system.
Full scan monitoring samples for four wells – 2A, 3A, 4A, and 5A) were taken quarterly and results reported to the health department.
All PFOA results received found no detection of the harmful chemicals in wells 2A, 3A and 4A, and all results from 2022 for well 5A are below the set MCL of 10.0 ng/L, the Water and Wastewater Authority reported on Monday.
Monitoring the wells will continue annually to ensure safe drinking water for Dalton Farms, officials said.
The update issued Monday said high levels of PFOA can cause health effects in animals, some of which may occur in humans.
But, the report said at the level of PFOA detected in the Dalton Farms water, exposure from drinking water and food preparation is well below PFOA exposure associated with health effects.
