NDMA in Drinking Water: MIT Study Finds Children Face Far Greater Cancer Risk Than Adults

# NDMA in Drinking Water: MIT Study Finds Children Face Far Greater Cancer Risk Than Adults

> **Quick answer:** A major MIT study published April 29, 2026 in *Nature Communications* found that children exposed to NDMA — a carcinogen in contaminated drinking water and certain medications — develop cancer at dramatically higher rates than adults. The reason: rapidly dividing cells in young bodies convert initial DNA damage into permanent, cancer-causing mutations before repair can occur. Adult cells rarely divide as fast, giving them time to fix the damage. Current EPA safety standards, built largely on adult animal data, may leave children dangerously under-protected.

NDMA in drinking water cancer risk for children is no longer theoretical. In a study that explains a decades-old mystery — why 22 children in one Massachusetts community developed cancer after their water supply was contaminated — MIT researchers have found a biological mechanism that reframes how we think about water safety standards for kids.
