I don't drink the water from the tap in my apartment. It tastes off. Perhaps I have lead pipes, the building went up in the fifties, but I don't know as you cannot see, smell or taste lead which is harmful, specially to kids.

If you suspect your plumbing may include lead pipes, use only cold water for drinking and cooking.
Run water for fifteen minutes for 15-30 second before drinking it.

Boiling water can intensify the lead.More information is at www.epa.gov/lead or (800) 424-5323 (LEAD).
