Orange & Rust Stains From Water in Palmetto Bay

Why Palmetto Bay sees so much of it

Large yards take a lot of irrigation, and many Palmetto Bay owners water from a shallow well rather than the county meter. Biscayne Aquifer groundwater often carries dissolved iron. When sprinkler water dries on stucco or concrete, the iron oxidizes and leaves orange deposits that build up with every cycle. The stains follow the spray pattern exactly, which is the giveaway.

If you have recently connected your house to county water but kept the well for irrigation, the stains will continue until the irrigation water is treated or switched. The house connection only changes what comes out of your faucets.

Inside the house

• Home on a drinking well: iron in the well water, often with hardness and sulfur.
• Home on WASD water with brown water after nearby main work: disturbed sediment. WASD has been installing new mains in parts of the village; if discoloration does not clear after running the cold tap, call WASD at 305-665-7477.
• One fixture: a corroding valve or galvanized section.
• Hot side only: the water heater.

What to test

Jorge tests iron and pH from the source that matches the stain: the irrigation line, the well spigot or the kitchen tap. On a well, he also checks hardness and odor, because iron, hardness and hydrogen sulfide often travel together, and the treatment must account for all of them. Some iron forms need oxidation before filtration; the test tells which approach suits your water.

He may also ask how long the well has been in use and whether stains have gotten worse. Iron levels in a well can change over time, and a treatment sized for an old reading may be undersized now.

Options

• Iron treatment on the irrigation line, sized to the pump's output.
• A whole-home well system if the house also drinks well water; see well water in Palmetto Bay and the well water system page.
• Moving irrigation to county water, which ends the iron but uses metered water.

Treatment prevents new stains; old deposits need a rust remover.

Watering rules

The Village reminds residents of Miami-Dade's watering schedule: odd-numbered addresses on Wednesdays and Saturdays, even-numbered addresses on Thursdays and Sundays, before 10 a.m. and after 4 p.m. The county applies those rules to private wells too. Watering on schedule also limits how much iron-laden water hits your walls.
