Antimony in Marathon Shores Florida Water

Unhealthy Levels of Antimony in the Water Supply of Marathon Shores Florida Homes

Antimony is a naturally occurring element that sometimes appears in drinking water at low concentrations and is also used in a few industrial processes. In water it generally exists as dissolved ions you can’t see, smell, or taste, so the only reliable way homeowners learn about it is through a lab test or a utility water quality report. For Marathon Shores residents, treating the main water line into your house is the most practical way to address elevated results and protect plumbing from the coastal corrosion stresses we see in the Florida Keys.

Because your incoming water supplies every faucet, shower, laundry machine and appliance, antimony present at the main can affect the whole household rather than a single fixture. Some people in the Keys notice subtle changes and call for testing after storms or when corrosion becomes visible; others prefer to be proactive based on lab results. Aiming for consistent reduction across the entire home — rather than relying on small point-of-use units — is especially useful in Marathon Shores where hard, coastal water and sea-air exposure can stress plumbing.
