Health Effects of Radium

  • Increased risk of bone cancer (radium accumulates in bones)
  • The body treats radium like calcium, storing it in bones
  • Lifetime cancer risk of ~1 in 10,000 at 5 pCi/L
  • No safe threshold for radioactive contamination

Health risk severity: High. Governed by the Radionuclides Rule.

How Radium Gets Into Drinking Water

  • Natural radioactive decay in underground rock formations
  • Groundwater sources (especially deep wells)
  • Mining and industrial waste
  • Higher in regions with specific geology (Midwest, parts of South)

What to Do About Radium in Rochester Water

  1. Reverse osmosis (NSF 58 certified) removes 90%+ of radium
  2. Ion exchange (water softeners) can reduce radium
  3. Point-of-use RO at kitchen tap is most cost-effective
  4. GAC filters alone are NOT effective for radium

Look for filters certified under NSF 58 for radium removal.
