Remove any sources of lead in your home: use wet methods to clean up dust with lead, clean often around windows and play areas, and wet mop floors often. Wash hands and toys often with soap and water. If you have concerns about lead in drinking water, contact your local health department. Flush water pipes for up to 2 minutes before drinking or drawing water, this is especially important when preparing baby formula. Use only the cold water tap for drinking, cooking, and especially for making baby formula. Regularly clean faucet aerators to clear out particles of lead trapped in the aerator. Use a faucet filter or pitcher to remove lead from water. Families can find specific water filter products and useful sources of information on filtering drinking water. The NSF International provides voluntary certifications on specific water filter products. Purchase lead-free faucets and plumbing parts.
