Overview

Nickel is a metal that occurs naturally and is used in plating and batteries.

In Florida, Nickel was reported by 90 community water systems serving about 1,206,612 people. 1 of those readings were above the federal legal limit, together serving 469 people. 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 Lakemont Ridge Home & RV Park in Polk County, at 17200% of it.

Where it comes from: Erosion of natural deposits; discharge from metal industries.

The standards

Legal limit (MCL)
0.1 ppm

Enforceable. A utility must stay at or under this.

Federal health goal (MCLG)
0.1 ppm

Health-based, not enforceable. Often lower than the limit, sometimes zero.

California public health goal
12 ppb

California OEHHA PHG (2001) For comparison the legal limit is 100 ppb.

Health effects the EPA associates with it: Can affect body weight, heart, and liver in animal studies; some people develop skin sensitivity.

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.
