What Cadmium is, and why it's regulated
What the EPA limit means
5 µg/L
Maximum Contaminant Level — the enforceable ceiling a supplier must stay under.
5 µg/L
Health goal (MCLG) — the level with no known health effect. It is a goal, not a legal limit, and is often zero for carcinogens.

Where Cadmium was found
The water suppliers reporting the highest levels, worst first. For lead and copper that is the 90th-percentile result the action level is written against; for Six-Year Review data, the 95th percentile of each system's samples.

Frequently asked questions about Cadmium
What is Cadmium in drinking water?
Cadmium leaches from galvanised pipes and industrial runoff; it damages the kidneys over time.
What is the EPA limit for Cadmium?
The EPA's Maximum Contaminant Level for Cadmium is 5 µg/L, and its health goal (MCLG) is 5 µg/L. A result above the limit means the supplier must act; the goal is the level at which no health effects are expected.
How common is Cadmium in US tap water?
Of the 33,728 water suppliers with results on file, 1,044 detected Cadmium — 3.1% of those tested.
