Iron is a common natural mineral, especially in groundwater and private wells. It is regulated for staining and taste, not health.
In Florida, Iron was reported by 465 community water systems serving about 1,152,773 people. Every reported reading was at or below the federal legal limit.
The highest reading relative to the limit was at Rainbow RV Resort in Polk County, at 3000% of it.
Where it comes from: Erosion of natural deposits; corrosion of iron pipes.
Enforceable. A utility must stay at or under this.
Health-based, not enforceable. Often lower than the limit, sometimes zero.
California has not published a PHG for this substance.
Health effects the EPA associates with it: Not a health concern. Iron causes rusty or orange staining on fixtures and laundry and a metallic taste.
Water at or under the legal limit meets federal safety standards. A reading above a health goal is not the same as being unsafe, and health goals are set purely on health without regard to cost or treatability. Both are shown so the margin is visible either way.
