Overview

An industrial chemical used to make pesticides and flame retardants.

In Florida, Hexachlorocyclopentadiene was reported by 29 community water systems serving about 784,873 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 North Springs Improvement District in Broward County, at <1% of it.

Where it comes from: Discharge from chemical factories.

The standards

Legal limit (MCL)
50 ppb

Enforceable. A utility must stay at or under this.

Federal health goal (MCLG)
50 ppb

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

California public health goal
2 ppb

California OEHHA PHG (2014)

Health effects the EPA associates with it: Kidney or stomach problems.

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.
