Including filter system and high-performance DDT filter.
DDT is a long-lived pesticide that can remain in the environment long after its use has stopped. Because it’s persistent in soils and sediments, small amounts may appear in water via runoff or disturbance of contaminated material, and you often won’t taste or smell it. If Marathon homeowners are concerned—whether you’re on municipal supply or a private well or cistern—a focused filtration plan can lower potential DDT exposure at every faucet in the house.
Clear-looking water can still carry trace contaminants, and DDT is one of the long-lasting organic chemicals commonly discussed for that reason. It binds to particles and natural organic matter, which influences its movement through water and the approach needed to treat it. The only way to be sure what’s in your water is through testing, especially important for local wells or storm-affected systems in the Keys; whole-house filtration treats water before it reaches showers, kitchens, and laundry in Marathon homes.
For reducing DDT, a whole-house activated carbon filter is generally the single most effective option for homeowners. Because DDT is hydrophobic, it adsorbs well onto high-quality carbon media. A correctly sized carbon tank can handle your home’s full flow so treated water is delivered to cooking, bathing, and washing throughout your Marathon property without adding chemicals.
Not all carbon systems perform the same, so media type, contact time, and sizing matter for DDT removal. Granular activated carbon (GAC) with adequate contact time and volume is often preferred for whole-house setups because it promotes adsorption as water passes through. Right-sizing for your household flow prevents water from rushing through untreated, and regular media replacement keeps effectiveness steady—especially important in Marathon’s coastal climate where corrosion and sediment can be considerations. Mr. Pure Water can assess your home and recommend the GAC whole-house system best matched to your needs.
