What this violation means

Radium-226 and Radium-228 occur naturally in groundwater, particularly in regions with granite or sandstone aquifers. Long-term ingestion increases the risk of bone, sinus, and other cancers because radium concentrates in bone tissue.

Recommended precautions

→Reverse osmosis and ion exchange (water softeners) remove radium.
→Boiling does NOT remove radium and may concentrate it.
→Private well users in radium-rich geology should test every 3–5 years.
