Including filter system and high-performance Strontium-90 filter.
Strontium-90 is a radioactive form of strontium that can appear in water at very low concentrations. Because it acts a lot like calcium, it can dissolve into groundwater and travel through distribution lines to reach a house via the main supply. You won’t be able to detect it by taste, smell, or sight—testing specifically for radionuclides is the only reliable way to know whether it’s present in your Delta water.
In Delta homes, water is used for much more than drinking: cooking, ice, bathing, and dental care all rely on the same supply. If water testing shows elevated strontium-90, the safest approach is to treat water at the point it enters the house so every faucet and shower is covered. Point-of-use devices can protect a single tap, but they won’t treat laundry, showers, or outdoor spigots—whereas a properly selected whole-house system delivers continuous protection throughout the home.
A whole-house water softener that uses ion exchange is often the most effective single-filter solution for reducing strontium-90. The resin in these systems swaps certain dissolved ions for sodium or potassium and can also remove other positively charged contaminants like strontium. Because strontium-90 is chemically strontium, it can be reduced by the same exchange process, making an entry-point ion exchange softener a practical choice for Delta homeowners who want treatment at every fixture.
To be effective in a Delta residence, an ion exchange softener should be sized for your household water use and overall mineral load. Regular regeneration with salt restores the resin so it continues capturing strontium, and routine maintenance keeps the system working reliably. Adding a prefilter can protect the resin from sediment and extend its life. Mr. Pure Water can review your lab results and recommend a whole-house ion exchange setup tailored to your home and needs.
