Manganese Staining in Highland Lakes Florida Water

Unhealthy Levels of Manganese Staining in the Water Supply of Highland Lakes Florida Homes

Manganese staining appears as dark brown or black marks on sinks, tubs, toilets and even on dishes or laundry, and can make fixtures look dingy despite regular cleaning. Often water that seems clear at the tap will oxidize when exposed to air and leave these stubborn discolorations, and you might sometimes notice a metallic taste or sediment collecting in a glass. Highland Lakes homeowners, especially in our hard-water Miami-Dade area, frequently find that the staining makes routine cleaning feel like a losing battle unless the source is treated.

Manganese is a natural mineral that can enter household water from groundwater and municipal supplies and may change over time. In Highland Lakes it tends to behave like a staining agent, building up on plumbing and fixtures rather than simply causing an off-taste, and hot water can make those marks more obvious on showers, tubs and clothing. If stains keep returning despite cleaning, that persistence usually points to manganese in the water rather than a housekeeping issue.
