Drinking water can contribute to lead poisoning in children due to which sources?

• A. Leaded solder, brass fittings and fixtures, and service lines
• B. Leaded gasoline in households
• C. A lead-free piping system
• D. Stainless steel service lines

Answer: (A)

Lead in drinking water mainly comes from materials used in the plumbing system that contain lead. When water sits in pipes for a while or has water chemistry that promotes corrosion, lead can leach out of materials like leaded solder used on copper pipes, brass fittings and fixtures, and old service lines that contain lead. This is why households with older plumbing can have higher lead levels in tap water, which is a concern for children’s health. Other options don’t fit because they aren’t sources of lead in household drinking water. Leaded gasoline was an environmental issue long ago and isn’t a direct home-water source today. A lead-free piping system and stainless steel service lines are designed to avoid lead and would not contribute to lead exposure.
