A TDS/ppm 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 a TDS meter in a prominent Huffington Post Article was not the lead concentration… it was the water's natural TDS level (which is dominated by minerals like calcium, magnesium, and sodium).

2020-04-06 · Total Dissolved Solids (TDS) are the total amount of mobile charged ions, including minerals, salts or metals dissolved in a given volume of water, expressed in units of mg per unit volume of water (mg/L), also referred to as parts per million (ppm). A TDS meter is based on the electrical conductivity (EC) of water. Additionally, is EC and PPM the same? Summary. ppm stands for parts per million & is the most common domestically used unit when measuring TDS. EC stands for
