Crystal River, FL Tap Water Quality — What Citrus County Residents Should Know

There's an irony to water quality in Crystal River. The city sits at the nexus of one of the world's most remarkable freshwater spring systems — Kings Bay produces hundreds of millions of gallons of pristine aquifer water daily, clear enough to see manatees from the surface. Yet residential tap water throughout Citrus County is often the least pleasant of any community in the Tampa Bay region, loaded with minerals and, in many homes, carrying a persistent sulfur odor that makes the water off-putting before it ever reaches a glass.
Understanding why this happens — and what to do about it — requires understanding the specific geology of this part of Florida.
The Floridan Aquifer in Citrus County
The Floridan Aquifer underlies essentially all of Florida, but it sits particularly close to the surface in Citrus County — in some areas just a few feet down, covered by thin sandy soils. This proximity is what makes the Crystal River springs possible: aquifer water under artesian pressure emerges naturally at dozens of locations throughout Kings Bay. It's also what makes residential water wells here tap directly into the raw aquifer with minimal geochemical buffering from overburden soils.
Raw Floridan Aquifer water in Citrus County carries significant dissolved calcium and magnesium (12-18 GPG hardness), naturally occurring hydrogen sulfide from sulfate-reducing bacteria in the aquifer, varying iron concentrations, and naturally occurring radionuclides including radium-226 and radium-228 from phosphatic limestone formations.
Is Crystal River Area Tap Water Safe?
For residents served by the City of Crystal River's municipal system: the utility monitors the water supply against EPA standards, publishes an annual Consumer Confidence Report, and maintains regulatory compliance. The treated municipal water is safe to drink by federal standards.
For the majority of Citrus County residents on private wells: safety depends entirely on your specific well's current condition. There is no ongoing monitoring of private well water — that responsibility falls to the homeowner. A well that was clean when drilled may have developed bacterial contamination, seen changes in iron or sulfide concentration, or been affected by nearby land use changes. Annual testing is the only way to know.
Radionuclides: The Issue Many Don't Know About
The Floridan Aquifer's naturally occurring radioactive materials don't get as much attention as PFAS or lead, but they're real and measurable in Citrus County well water. Radium-226 and radium-228 occur naturally in phosphatic limestone, and well water testing in this area frequently shows combined radium above 2 pCi/L, with some wells exceeding the EPA's 5 pCi/L MCL.
Radium accumulates in bone tissue with long-term exposure. At concentrations within regulatory limits, individual risk is considered low — but for households where members have been drinking the same well water for decades, or for homes with young children whose developing bodies absorb minerals more readily, reducing radionuclide exposure through home treatment is a reasonable decision. Water softeners provide partial radium removal through ion exchange. Reverse osmosis provides more complete removal.
What Citrus County Homeowners Should Do
Municipal customers: read the annual CCR when it's published. Look at the actual detection levels for TTHMs, HAAs, and radionuclides. Consider a whole-house carbon filter for chloramine taste/odor and an under-sink RO for drinking water.
Well water customers: get a comprehensive water test annually. Test for hardness, iron, sulfide, pH, bacteria (total coliform and E. coli), and nitrates at minimum. If your well is near agricultural operations or older septic systems, extend the panel. Test for radionuclides every few years given this region's geology.
The H2O Heroes team tests water throughout Crystal River and Citrus County at no charge. We explain what we find in plain terms and recommend treatment only for what you actually need — not for what we'd like to sell. If your well water is fine by every measure, we'll tell you that too.
