TDS (Total Dissolved Solids) measures all dissolved substances in water, while hardness specifically measures calcium and magnesium ions, indicating that TDS includes hardness but also other components. In India, acceptable TDS levels for drinking water are up to 500 mg/L, with hardness classifications ranging from soft to very hard. There is an indirect correlation between TDS and hardness, as increased calcium and magnesium levels raise both, but high TDS can occur without high hardness due to other disso
