Open Orange County Utilities' 2025 Drinking Water Report — the official document, published by the county — and you'll find this line: combined radium 226 + 228: 1.5 pCi/L. The legal limit is 5, so there's no violation. But radium is a radioactive mineral, and independent health guidelines put the no-significant-risk level far below what's legally allowed.
Where does it come from?
Nobody spilled it. Central Florida's drinking water sits in limestone aquifer rock, and that rock contains naturally occurring radioactive minerals. The water dissolves trace amounts as it sits underground — then it flows to your tap. Every glass, every pot of pasta, every shower. You can't taste it, smell it, or see it. The county's test is the only reason anyone knows it's there.
What gets it out.
Here's the good news: reverse osmosis removes radium — along with the trihalomethanes, haloacetic acids, bromate, and hexavalent chromium that also showed up above health guidelines in Orlando-area water. A whole-home system plus RO at the kitchen tap addresses every contaminant on the above-guideline list.
