Orange & Rust Stains From Water in Dania Beach

Where the stains come from

• Irrigation wells: the usual cause. Iron in the groundwater turns orange on surfaces the sprinklers hit.
• A private drinking well: can stain sinks, tubs and laundry as well.
• Old galvanized pipes or fittings: can release rust inside a home, usually as discolored water after it sits.
• Fertilizer: some lawn products contain iron and leave similar marks.

Why city water is rarely the cause

The City of Dania Beach softens and filters its water at the plant: lime softening followed by filtration, blended with nanofiltered water, before disinfection. Broward County treats with lime and ferric chloride, then filters. Iron-orange staining from the sprinklers points to a separate source, which in most cases is a well feeding the irrigation system.

What to test

Jorge tests the irrigation water for iron, pH and hardness, and for sulfur signs, since iron and hydrogen sulfide often appear together in groundwater. If the house is on a well, he tests indoors too. The level of iron and the pH decide which treatment works.

Treatment options

• Iron filter on the irrigation line: oxidizes and filters iron before it reaches the sprinklers.
• Whole-house well treatment: if the home also uses the well, a configured well water system handles iron, sulfur and hardness together.
• Switching irrigation source: where available, some owners irrigate with utility water instead; ask your provider about rules and rates.

Existing stains need a cleaner made for rust; a filter prevents new ones but does not remove old ones.

Well permits in Broward

In Broward County, wells 12 inches in diameter or smaller, including irrigation wells, need a permit from the Florida Department of Health in Broward County to be built, repaired or abandoned, and the work must be done by a licensed water well driller. See well water treatment in Dania Beach.

Keep stains from coming back

Once the iron is handled, clean the existing stains with a product made for rust and check sprinkler heads that spray walls, pavers or pool decks directly. Re-test the irrigation water periodically, because well water can change with the seasons, heavy rain and nearby construction.
