Manganese Staining in Mims Florida Water

Unhealthy Levels of Manganese Staining in the Water Supply of Mims Florida Homes

Manganese staining appears as dark brown or black marks on sinks, tubs, toilets and even on laundry and dishes. In Mims households—many of which use well water—manganese can be invisible at the tap but oxidize when exposed to air, leaving stubborn discoloration and sometimes a metallic taste or settling sediment in glasses. The result is fixtures and fabrics that look dingy and are harder to keep clean despite frequent scrubbing.

Manganese is a natural mineral that can enter homes from groundwater and may change in concentration over time. In Mims and elsewhere on the Space Coast it tends to act as a stain-maker, building up on plumbing surfaces and inside fixtures rather than just affecting flavor. Hot water often makes these marks more obvious on showers, tubs and laundry, and when staining returns after cleaning it usually indicates the source is in the water supply, not your cleaning habits.
