Is tap water with PFAS contamination safe for making baby formula?
No. Peer-reviewed research indicates that PFAS in drinking water can lead to metabolic issues and damage to cellular function in developing embryos.
What's actually in it
PFAS are a group of chemicals often found in public water supplies. These substances do not just pass through the body. A 2026 study in Environ Health Prev Med shows that these chemicals can build up in your blood after you drink contaminated water. Once they are in your system, they can cause metabolic changes, according to a 2026 study in Environ Int.
What the research says
The science is clear that these chemicals pose risks to development. A 2026 study in Environ Res found that even trace levels of PFAS in drinking water can harm the mitochondria in embryos. The researchers discovered that this damage can last across 3 generations. This means the impact of the water you drink today could affect your child and their future children.
Other research highlights the link between contaminated water and serious health outcomes. A 2026 study in Environ Res looked at PFAS in public water and found links to liver cancer mortality. Additionally, a 2026 study in J Expo Sci Environ Epidemiol investigated the connection between PFAS in public water at birth and childhood cancer rates.
