Contaminant

MCL (year promulgated)

Source

Health Effect

Combined radium-226/-228

5 pCi/L (1976)

Naturally occurs in some drinking water sources.

Some people who drink water containing radium –226 or -228 in excess of the MCL over many years may have an increased risk of getting cancer.

(Adjusted) Gross Alpha

15 pCi/L (not including radon or uranium) (1976)

Naturally occurs in some drinking water sources.

Some people who drink water containing alpha emitters in excess of the MCL over many years may have an increased risk of getting cancer.

Beta Particle and Photon Radioactivity

4 mrem/year (look-up table) (1976)

May occur due to contamination from facilities using or producing radioactive materials.

Some people who drink water containing beta and photon emitters in excess of the MCL over many years may have an increased risk of getting cancer.

Uranium

30 µg/L (2000)
