Sulfur Bacteria in Coral Gables Florida Water

Unhealthy Levels of Sulfur Bacteria in the Water Supply of Coral Gables Florida Homes

Sulfur bacteria are naturally occurring microbes that can appear in private wells and, less commonly, other water supplies. Many Coral Gables homeowners first notice them as a rotten-egg smell—often stronger from hot water—along with a slimy feel or cloudy appearance. While sulfur bacteria aren’t typically tied to illness, heavy growth makes water unpleasant to use and can lead to staining and buildup on fixtures and appliances, a concern in our hard-water area fed by South Florida’s limestone aquifer.

The familiar sulfur odor is frequently caused by hydrogen sulfide gas and by the conditions that let sulfur bacteria thrive. These organisms consume sulfur compounds and can form slimy layers inside pipes, water heaters, and toilets, protecting other nuisance microbes and making cleaning feel ineffective. If the smell in your Coral Gables home comes and goes or becomes stronger after water sits, that pattern often points to growth inside the plumbing rather than a one-time source.
