Iron in Water

Ever seen orange streaks on the sides of buildings? These unsightly stains often occur when water that's high in iron is used for irrigation.

In fact, most Florida well water is high in iron, and can lead to rust deposits on anything the water comes in contact with, even plants.
Iron concentrations above a certain level can also cause blockages in drip irrigation systems. And over time, excess amounts of iron can make it difficult for plants to take up specific nutrients like phosphorous.

If you suspect your water is high in iron, start by having it tested.
Once you know the concentration of iron in your water, your options to treat excess iron include water softeners, oxidizing filters, and combined chlorination/filtration systems.
