Sodium occurs naturally in Florida groundwater, and more so near the coast. It is not a health concern for most people, but matters for anyone on a sodium-restricted diet.
In Florida, Sodium was reported by 1,075 community water systems serving about 6,717,435 people. 6 of those readings were above the federal legal limit, together serving 48,969 people.
The highest reading relative to the limit was at Holley-Navarre Water System in Santa Rosa County, at 148% of it.
Where it comes from: Erosion of natural deposits; saltwater influence near the coast; water softeners.
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: Not federally regulated for health. People on a very low-sodium diet (for blood pressure or heart conditions) may want to account for sodium in their water. At high levels it can give water a salty taste.
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 1,075 systems that reported Sodium.
