Nitrite is a form of nitrogen closely related to nitrate, usually from fertilizer, sewage, or natural deposits.
In Florida, Nitrite was reported by 89 community water systems serving about 6,935,741 people. Every reported reading was at or below the federal legal limit. It was measured by 1,559 systems in all, so it was detected in 6% of the systems that tested for it.
The highest reading relative to the limit was at Wellington WTP in Palm Beach County, at 100% of it.
Where it comes from: Runoff from fertilizer; sewage; erosion of natural deposits.
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: Serious illness in infants under six months (blue-baby syndrome) if untreated.
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.
