Chromium occurs naturally and is also used in industry. The legal limit covers total chromium.
In Florida, Chromium (total) was reported by 223 community water systems serving about 1,294,266 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 14% of the systems that tested for it.
The highest reading relative to the limit was at Holliday Manor in Polk County, at 100% of it.
Where it comes from: Discharge from steel and pulp mills; 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: Allergic dermatitis (skin reactions).
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 223 systems that reported Chromium (total).
