Chlorine Dioxide in Marathon Florida Water

Unhealthy Levels of Chlorine Dioxide in the Water Supply of Marathon Florida Homes

Chlorine dioxide is a powerful disinfectant sometimes used in drinking water systems to control microbes. When levels are higher than homeowners prefer, it can give tap and shower water a chemical taste or a sharp, oxidizing odor you might notice after spending time on the dock or returning from a day at Sombrero Beach. Some people also report drier-feeling skin or hair after bathing when that scent is present. If your Marathon water suddenly seems harsher than usual, or you detect a persistent chemical smell, chlorine dioxide and its related smells are worth investigating.

Because chlorine dioxide reacts with organic material, it can form byproducts that affect taste and odor even when water looks clear—often becoming more noticeable in hot water or after water sits in the plumbing. In a Keys home, where many properties face coastal salt air and occasional storm exposure that can accelerate corrosion, treating incoming water at the point of entry addresses odors throughout the house rather than only at a single tap. If you’re already using bottled drinking water but still smell chemicals when showering or doing laundry, whole-house treatment makes a bigger, more consistent difference for cooking, bathing, and cleaning around Marathon.
