Including filter system and high-performance Strontium-90 filter.
Strontium-90 is a radioactive form of strontium that can show up in water at very low concentrations. Because it behaves like calcium, it travels with groundwater and can enter your house through the main supply line without any taste, smell, or color to give a warning. The only reliable way to know if it’s present in Stock Island water is to test specifically for radionuclides.
In Stock Island households, water is used for much more than drinking—cooking, ice, bathing, and oral hygiene all rely on the same supply—so any contaminant found in testing is best addressed at the point where water enters the home. Point-of-use devices protect a single faucet, but they won’t shield appliances or showers across a home. A correctly chosen whole-house system gives consistent protection at every fixture throughout your Stock Island residence.
When the goal is to reduce strontium-90 throughout a house, a whole-house water softener using ion exchange is frequently the single most effective filter option. The resin inside the softener swaps certain dissolved ions for sodium or potassium and can also capture positively charged contaminants like strontium. Because strontium-90 is chemically strontium, it can be lowered through that exchange process, making an ion exchange softener a practical choice for treatment at the home’s entry point in the Florida Keys.
To perform reliably in Stock Island’s hard, mineral-rich water, an ion exchange softener must be sized to your household demand and the local mineral load. Regular regeneration with salt restores the resin so it continues removing strontium over time, and routine maintenance preserves long-term performance. In many cases adding good prefiltration protects the resin from sediment and scale that can shorten service life—Mr. Pure Water can review your test results and recommend a whole-house softener setup tailored for Stock Island homes.
