Overview

TDS is the total of all dissolved minerals in the water (calcium, sodium, chloride, sulfate, and more). It is a general measure of mineral content, regulated for taste.

In Florida, it was found in 1,065 community water systems serving about 4,362,588 people.

The highest reading relative to the limit was at City of North Port Utilities in Sarasota County, at 1290% of it.

Where it comes from: Natural minerals in the source water.

The standards

Secondary standard
500 ppm

Enforceable. A utility must stay at or under this.

Federal health goal (MCLG)
N/A ppm

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

Health goal
Not set

Nobody has published a health goal for this substance, official or otherwise.

Health effects the EPA associates with it: Not a health concern. High TDS can make water taste salty, bitter, or metallic and can leave spots and scale.

The health goal is set on health alone. The legal limit is set as close to it as is technically and economically feasible, so treatment cost and available technology are written into the number a utility is measured against. A system at or under the limit is meeting the standard it is required to meet. Both numbers are shown so the distance between them is visible.

What removes it

Total dissolved solids is the sum of everything dissolved in the water rather than any one substance, so it is a summary number, not a target. Reverse osmosis is what reduces it. A softener does not: it exchanges one dissolved mineral for another and leaves the total roughly where it was.

Treatment guidance describes the methods generally used for this contaminant. What your own tap actually carries depends on your plumbing and your service line as much as on the utility, which is what a test at the house tells you and an annual report cannot.
