Zinc occurs naturally and from galvanized plumbing. It is regulated for taste.
In Florida, Zinc was reported by 429 community water systems serving about 1,346,310 people. Every reported reading was at or below the federal legal limit.
The highest reading relative to the limit was at Four Lakes in Lake County, at 182% of it.
Where it comes from: Natural deposits; corrosion of galvanized 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 at these levels. High zinc gives water 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.
