Orange & Rust Stains From Water in Coconut Creek

Why irrigation water stains

Shallow groundwater in South Florida often carries dissolved iron. Treated city water has been through softening and filtration at the County plant; irrigation pumped straight from a well has not. When it sprays on stucco, concrete, pavers or screen enclosures, the iron oxidizes in air and sunlight and leaves orange streaks that build up season after season.

Stains are worst where the same wall, walkway or pool deck gets hit every watering cycle. Over months, light orange becomes deep rust that is hard to remove without damaging the surface.

Indoor stains

• Private well: iron stains sinks, toilets and laundry.
• Iron bacteria: Florida's Department of Health lists red stains, swampy or oily smells, and red slimy growth in the toilet tank as signs.
• Hydrant flushing: Coconut Creek flushes hydrants when testing shows a main needs it. The city advises avoiding tap water, laundry and dishwashers during flushing, and if water is discolored, waiting a few minutes and running cold water until it is clear. It says there is no health hazard associated with discolored water.
• Aging plumbing: a plumbing issue rather than a water treatment one.

What to test

Jorge tests iron at the sprinkler or faucet that stains, along with pH and hardness, which affect how iron behaves and what treatment works. If indoor water shows no iron and the irrigation water is high, the fix is focused on the irrigation line.

Iron bacteria and dissolved iron call for different approaches, so the test includes a look at any slime or deposits around the pump, well head or toilet tank.

Options for irrigation stains

• Iron treatment on the irrigation line, sized for the pump's flow.
• Redirecting sprinkler heads away from walls, walkways and pool decks.
• For common areas, asking your HOA or property manager about the irrigation source.

Use cleaners approved for your surface; some damage pavers or paint.

Options for a drinking well

A well water system configured from the well's test, which may include oxidation and filtration for iron and a softener for hardness, in the right order so each stage is protected. See well water in Coconut Creek.
