Uranium in your water
Health effects
Uranium occurs naturally in rock and dissolves into groundwater, with extra contributions from mining in some regions. It is both a radioactive and a toxic metal; long-term exposure mainly damages the kidneys and increases cancer risk. It is widespread in Western groundwater.
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.
Health guideline (EWG)
0.43 ppb
Federal legal limit (MCL)
