What CDC and AAP guidance actually says
Why infants are more vulnerable
Infants drink far more water relative to their body weight than adults, and their kidneys and detoxification systems are still developing - the same contaminant level poses a proportionally larger exposure for a baby than an adult.
Key takeaway
The CDC recommends parents in areas with lead service lines use cold, filtered water for infant formula preparation, since lead cannot be removed by boiling.
What CDC and AAP guidance covers
| Guidance | Why |
|---|---|
| Always use cold tap water for mixing | Hot water dissolves more lead from pipes and fixtures |
| Let the tap run before drawing water | Flushes water with the most contact time with plumbing |
| Boiling does not remove lead | A common misconception - boiling can concentrate it slightly |
| Consider filtration certified for lead reduction | Especially relevant with lead service lines or older plumbing |
Frequently asked questions
- Is bottled water safer for formula?
- Not automatically - quality varies by brand, and bottled water isn't guaranteed contaminant-free either.
- Does boiling make tap water safe for formula?
- Boiling addresses certain microorganisms but does not remove lead or most chemical contaminants.
