Including filter system and high-performance Strontium-90 filter.
Strontium-90 is a radioactive form of strontium that can occur in water at very low concentrations. Because it behaves much like calcium in natural systems, it can dissolve into groundwater and travel through the main line into a house without any change in taste, smell, or appearance to warn you. The only reliable way Darsey homeowners can learn whether it’s present is to have their water tested specifically for radionuclides.
In Darsey households, water is used not just for drinking but for cooking, making ice, bathing, and brushing teeth — so any contaminant found in your supply is a concern throughout the home. If your test results show elevated strontium-90, the practical approach is to treat water at the point it enters the house so every fixture is covered. Point-of-use cartridges protect a single faucet, but they won’t treat showers, laundry, or outdoor taps the way a properly chosen whole-house system will.
For removal of strontium-90, a whole-house water softener using ion exchange is often the most effective single-filter solution. The resin in the softener swaps certain dissolved ions in your water for sodium or potassium and can also capture positively charged contaminants like strontium. Because strontium-90 is chemically strontium, it can be reduced by this exchange process, making an entry-point ion exchange softener a sensible choice for Darsey homes that want treatment at every tap.
An ion exchange softener must be sized to match your household’s daily water use and the hardness and mineral load of your water to perform well. Regular regeneration with salt restores the resin so it continues removing strontium, and routine maintenance helps sustain that performance. In many situations adding a quality prefilter protects the softener media from sediment and extends its life. Mr. Pure Water can review your Darsey test results and recommend a whole-house configuration that targets strontium-90 effectively without unnecessary complexity.
