A University of Arizona study looked at all births in New Hampshire from 2010 to 2019. Researchers compared mothers who used wells downstream of PFAS sites with mothers who used upstream wells. The downstream group had more infant deaths in the first year, more preterm births, and more babies with low birth weight.
The study focuses on long-chain PFAS such as PFOA and PFOS, which stay in soil and move into groundwater. The authors say cleanup and home filters could protect pregnant women and infants.

Discussion questions
- Would you want a home water filter if your water came from a well? Why or why not?
- Have you heard about chemicals like PFOA or PFOS before? What do you think people should do about them?
- What steps could a community take if a study finds chemical contamination in local wells?
