The standards

Legal limit (MCL)
10000 ppb

Enforceable. A utility must stay at or under this.

Federal health goal (MCLG)
10000 ppb

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

California public health goal
1.8 ppm

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.
