Don’t immediately move to Mars. It’s manageable. Run the tap for 1-2 minutes before drinking. That flushes out water that sat in pipes. Use cold water for cooking and drinking. Never use hot tap water for baby formula or soup.
Consider a filter. Some pitcher filters (like those with NSF/ANSI Standard 53) remove lead. Or install a faucet-mounted filter. It’s a cheap fix that makes your water taste like a mountain stream.
If your whole house has lead pipes? That’s a bigger job. Call a plumber. But don’t panic. Millions of homes had lead pipes. You’re not alone. You’re just part of a historic club.
