Dissolved Solids
Dissolved Solids refers to any minerals, salts, or metals that are dissolved in water - think of it like invisible particles in water. Water treatment professionals measure and control these substances because they affect water quality and taste. When you see this term (often abbreviated as TDS - Total Dissolved Solids) in a resume, it usually means the person has experience in water quality testing, treatment plant operations, or environmental monitoring. It's similar to checking the purity of water, much like checking food quality in a restaurant.
