The infants of New Hampshire mothers whose water sources flowed through sites contaminated by PFAS experienced significantly higher rates of adverse health outcomes, and even death, according to a recent study published in Proceedings of the National Academy of Sciences.
In short:
- Mothers exposed to PFAS-contaminated water had 191% higher risk of their newborns dying within the first year of life, compared to mothers whose water sources were not downstream from contaminated sites.
- Exposed mothers were also 168% more likely to give birth extremely prematurely (before 28 weeks of gestation) and 180% more likely to have babies with extremely low birth weights (less than 2.2 lbs).
- Based on these results, the study authors estimate that PFAS cost the U.S. approximately $8 billion annually due to impacts to infant health.
