What is TDS in Water & Why Should You Measure It?

Total Dissolved Solids (TDS) are the total amount of mobile charged ions, including minerals, salts or metals dissolved in a given volume of water.  TDS which is based on conductivity, is expressed in parts per million (ppm).  TDS includes any conductive inorganic elements present other than the pure water molecules (H20) and suspended solids.

TDS affects everything that consumes, lives in or uses water, from fish and plants to plumbing and laboratories. Water with a hight TDS is known as hard water. Acid rain created hard water.

Hard acidic water then is your greatest enemy. It will destroy every fond hope you have by striking you down when you should be enjoying the fruits of your labors. Crippled joints, repeated surgeries, enlarged hearts, hardened arteries, gall stones, kidney stones, hearing problems, forgetful minds, all draw your activities from the great out-of-doors into creaking rocking chairs, and finally into bed-ridden old folks homes.

The average person drinks about a gallon of water per day. Adding up the cups of coffee, tea, soft drinks, food, and water, this gallon isn’t too much. At a gallon a day, the average person drinks up to 450, 12 ounce glasses of solids during their life. Think of it… 450 glasses of mineral solids in your system during a lifetime.

For people, appropriate minerals (TDS level) in the water you drink, the more efficiently your body’s cells are hydrated. The higher the TDS level in water, the greater the probability of harmful contaminants that can pose health risks and/or hinder the absorption of water in the body.
