What are total dissolved solids or TDS?
Total Dissolved Solids Or TDS is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid. TDS is sometimes referred to as parts per million (ppm). You can test water quality levels using a digital TDS meter.
Primary sources for TDS in Receiving Water
are agricultural & urban runoff, clay-rich mountain waters, leaching of soil contamination, & point source water pollution discharge from industrial or sewage treatment plants.
