Water contamination affects all life forms and is a critical concern today. Pollutants from human-induced as well as natural sources flow through groundwater and into drinking water.

TDS stands for total dissolved solids. Like the name suggests, TDS testers allow users to evaluate the amount of ionized solids dissolved in a liquid or solution without going through the trouble of evaporating the liquid and weighing the residual elements. H2O has a TDS value of zero—in other words, there are no dissolved elements in pure water that have an electrical charge. Because ionized solids will boost the electrical conductivity (EC) of water, the amount of TDS is gauged using an electrical current that measures EC levels.
You may have heard of ORP, but what does it mean and what role does it play in water-quality testing? We’ve laid out the basics of ORP to help you get up to speed.
