Participants provided blood and urine samples to CDC/ATSDR for analysis. The CDC/ATSDR evaluated the data from the exposure assessment to better understand PFAS exposure in the community.

The CDC/ATSDR provided the results directly to the participants, and summarized the results in a fact sheet in June 2020.

Meeting Drinking Water Standards

Artesian Water and the city of New Castle Municipal Services Commission are treating the public drinking water to remove the PFAS compounds, PFOS and PFOA, so the water does not exceed EPA’s Health Advisory Level.

The drinking water supplied by Artesian Water and the city of New Castle continues to meet federal and state Safe Drinking Water Act standards.
