What is TDS? What Does A TDS Meter Measure?

 

TDS stands for Total Dissolved Solids which is related to the total charged mineral content of water. TDS can be easily determined by measuring the conductivity of a water sample, which is exactly what inexpensive TDS probes do. If you start with deionized water (which has a TDS of zero), and expose it to minerals that contain sodium, calcium, and magnesium ... the water's TDS rises. This is why there's no such thing as deionized water in nature. Depending on a region’s geology, natural TDS levels can vary across the US, and this variability has nothing to do with the water quality (except in extreme cases when the water is too salty to drink).

 

What Does a TDS Meter Not Measure?

 

Because TDS is an aggregate measure of charged compounds in water, uncharged things like motor oil, gasoline, many pharmaceuticals, and pesticides do not contribute to a TDS measurement. For example, the glass on the left in this article's header image contains deionized water with Malathion (an organophosphate pesticide) dissolved into it at 100 times higher concentration than allowed by the EPA for drinking water, and the TDS probe reads 000.

 

What About Lead, Arsenic or Chromium 6?

 

Even though these toxic metals are charged when dissolved in water, a TDS meter does not give meaningful information about their presence or concentration in water. There are two main reasons for this:

 

A TDS meter is a nonselective measurement and cannot differentiate among different ions. A more sophisticated piece of equipment is needed to perform those types of measurements. The value of 184 that was measured using an inexpensive TDS meter in a prominent Huffington Post Article was not the lead concentration… it was the TDS level (which is dominated by minerals like calcium, magnesium, and sodium) of the tap water.

 

A TDS meter is not sensitive enough to measure toxic levels of lead, chromium-6 or arsenic, even if they are present in a sample. This is because the reading displayed on an inexpensive TDS meter is in parts per million, while lead chromium-6, and arsenic are toxic at part per billion concentrations (1000 times lower). Using a TDS meter to measure ppb lead concentrations in tap water is like trying to use a car’s odometer to measure a child's growth spurt…. It's the wrong tool. For example, the water sample shown on the right hand side of this article's header image has lead concentrations 100x the EPA limit, and the TDS reading teetered between 000 and 001.
