Overview
Silver can enter water from natural deposits or some filtration media. It is a secondary (aesthetic) standard.
In Florida, Silver was reported by 95 community water systems serving about 94,668 people. Every reported reading was at or below the federal legal limit.
The highest reading relative to the limit was at Oakview MHP in Desoto County, at 340000% of it.
Where it comes from: Erosion of natural deposits; some treatment media.
The standards
Secondary standard
0.1 ppm
Enforceable. A utility must stay at or under this.
Federal health goal (MCLG)
Not set
Health-based, not enforceable. Often lower than the limit, sometimes zero.
California public health goal
Not set
California has not published a PHG for this substance.
Health effects the EPA associates with it: Regulated as a secondary standard; at very high long-term levels it can cause a harmless skin discoloration (argyria).
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.
