Is it safe to drink tap water in areas with elevated lead levels if you have a family head-and-neck cancer history?

What's actually in it

Lead in drinking water comes from old service lines, lead solder in pipes, and brass fittings. The US EPA action level is 15 parts per billion, but many public health experts argue there's no safe lead level. People with family history of cancer have higher baseline risk, which makes modifiable exposure reductions more impactful.

Water utilities typically flag elevated lead in their Consumer Confidence Reports, but the reports are sent once a year and easy to miss.

What the research says

A 2026 study in Otolaryngol Head Neck Surg examined lead in drinking water and head and neck cancer in the United States. The analysis found a positive association between higher water lead levels and head and neck cancer incidence across US regions. The effect was dose-dependent.

For anyone with relevant family history, get your water tested for lead (most utilities offer free tests, or home test kits run about $30). Install a NSF 53 certified lead-removing filter on the kitchen tap. Always flush the cold tap for 30 seconds before filling a glass in the morning. Don't cook with hot tap water, ever; hot water pulls more lead out of pipes.
