Including filter system and high-performance Strontium-90 filter.
Strontium-90 is a radioactive form of strontium that can exist in water at very low concentrations. Because it behaves much like calcium, it moves with groundwater and can enter a home through the main supply line — whether your water comes from the Florida Keys Aqueduct Authority, a private well, or a cistern. You can’t taste, smell, or see it, so the only reliable way to know if it’s present is to have your water tested for radionuclides.
In Cudjoe Key houses, water is used for much more than drinking — cooking, making ice, bathing, and brushing teeth all matter. If tests show elevated strontium-90, the safest approach is to treat incoming water so every fixture is covered. Point-of-use filters help at individual taps but won’t protect showers, outdoor hoses, or irrigation. A correctly chosen whole-house system gives consistent protection across the whole home, from Cudjoe Gardens to Cudjoe Shores.
When looking specifically to reduce strontium-90, a whole-house water softener that uses ion exchange is often the most effective single-filter option. The resin in the softener swaps certain dissolved ions for sodium or potassium and can also capture positively charged contaminants like strontium — so the same chemistry that softens moderate-hardness Keys water can help reduce strontium as it enters the plumbing. Installed at the entry point, an ion exchange system treats water for the whole home.
To perform well in Cudjoe Key’s warm, coastal environment, an ion exchange softener must be sized for your household water use and the mineral content of your supply. Routine regeneration with salt restores the resin so it continues to remove strontium over time, and good maintenance preserves performance. Protecting the softener with prefiltration also helps prevent sediment and scaling from shortening media life.
