Cobalt in Saint Augustine South Florida Water

Unhealthy Levels of Cobalt in the Water Supply of Saint Augustine South Florida Homes

Cobalt is a naturally occurring metal that can enter drinking water when it dissolves from certain rocks and soils or through industrial sources. In most homes it’s found at low levels, but homeowners sometimes choose to address it when lab results show higher-than-expected amounts. Because cobalt is usually colorless and has no distinct taste or smell, testing is the only reliable way to detect it — many Saint Augustine South residents include metals like cobalt when they screen their water, especially given our hard municipal groundwater.

When metals are a concern, treating water at the point it enters your house makes sense for everyday uses like cooking, drinking, bathing and laundry. Cobalt can occur with other dissolved metals, and the most effective treatment depends on its chemical form and the overall water chemistry — factors homeowners in St. Johns County often consider because of hard water and coastal humidity. Start with a good lab test, then match those results to a whole-home solution that targets dissolved metal ions consistently across every tap.
