How much TDS in water is safe for us?

Total Dissolved Solids (TDS) levels in drinking water should ideally be below 500 mg/L for safe consumption. Water with TDS levels between 500 and 1,000 mg/L may still be acceptable but could affect taste and health if consumed long-term. Levels above 1,000 mg/L are generally considered unsuitable for drinking. Regular testing is recommended to ensure water quality remains within safe limits.
