In Florida, Xylenes (total) was reported by 30 community water systems serving about 251,810 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 2% of the systems that tested for it.
The highest reading relative to the limit was at Water Oak Country Club Estates in Lake County, at 2% of it.
Where it comes from: Discharge from petroleum and chemical factories.
Enforceable. A utility must stay at or under this.

California OEHHA PHG (1997) For comparison the legal limit is 10 ppm.
Health effects the EPA associates with it: Nervous system damage.
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.
Showing the 25 highest of 30 systems that reported Xylenes (total).
