What this violation means

Uranium in drinking water is both a chemical toxin (kidney damage) and a radiological hazard (increased cancer risk). It's most commonly found in groundwater near uranium ore deposits or former mining activity in the Western US.

Recommended precautions

→Reverse osmosis is the gold standard for removing uranium.
→Ion exchange systems work but must be sized correctly for uranium.
→If you live near former mining sites, test for uranium even if not required.

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.

4.1 MG/L

First Reported

Most Recent

Apr 2022

What this violation means

Fluoride at the optimal level (~0.7 mg/L) reduces tooth decay, which is why most US utilities add it. The MCL of 4.0 mg/L exists to protect against skeletal fluorosis from naturally high-fluoride groundwater, while the EPA's secondary standard of 2.0 mg/L addresses dental fluorosis in children.

Recommended precautions

→Reverse osmosis removes fluoride; standard carbon filters do NOT.
→If your child uses fluoride toothpaste and drinks fluoridated water, supervise brushing to limit ingestion.
→Bone meal supplements often contain fluoride and should be used cautiously.
