Cadmium in your water
Health effects
Cadmium enters water from corroded galvanized pipes and from industrial and mining discharges. Long-term exposure mainly damages the kidneys and can weaken bones. It is toxic even at low levels over time.
The guideline vs. the legal limit
The federal legal limit is the maximum allowed by law. The EWG health guideline is what independent scientists consider safe — it is often far stricter.
