Why babies deserve a little extra care

CDC notes that infants who drink formula prepared with lead-contaminated tap water may be at higher risk because they drink a lot of water for their size. EPA estimates infants who mostly drink formula can get 40% to 60% of their lead exposure from drinking water.

Simple steps for Palos Heights parents

  • Use cold tap water to make formula. Hot water can carry more lead.
  • Run the tap after water has been sitting for hours before filling the bottle.
  • If your service line is lead or unknown, or you just want peace of mind, use water from a filter certified to NSF/ANSI 53 for lead, or bottled water.
  • Remember: boiling kills germs but does not remove lead.

During a water emergency

If local officials say tap water isn't safe, CDC says to use bottled water for formula until they say otherwise. Ready-to-feed liquid formula needs no water at all.

As of December 31, 2025, the City of Palos Heights reports it has not located or verified any lead service lines in its service area. More on lead in Palos Heights.

Quick questions

Can I use tap water for formula?

CDC says most of the time it's safe to mix powdered formula with tap water, filtered or unfiltered, following the manufacturer's instructions. If you're unsure about your tap water, contact your local health department.

Does boiling remove lead?

No. Boiling kills germs but does not remove lead. Use cold water and, if you're concerned about lead, a filter certified to NSF/ANSI 53 for lead or bottled water.
