PFAS and Pregnancy: What Expectant Parents Should Know
PFAS in drinking water during pregnancy and how to reduce exposure.
Why PFAS matters during pregnancy
PFAS cross the placental barrier and have been detected in breast milk. Studies associate PFAS exposure with lower birth weight, preeclampsia risk, and thyroid disruption during fetal development. The developing immune system is particularly vulnerable.
What the research shows
A 2022 meta-analysis in Environmental Health Perspectives found consistent associations between prenatal PFAS exposure and reduced birth weight. The EPA's 2024 standard of 4 ppt reflects these concerns.
Reducing exposure
A point-of-use reverse osmosis system at the kitchen tap provides the highest PFAS removal rate (90-99%). Granular activated carbon filters are also effective. Check NSF P473 certification. Look up your city's PFAS levels.
