The secondary drinking water standard limit for total dissolved solids (TDS) is established at 500 mg/L. This guideline is set by the Environmental Protection Agency (EPA) to address aesthetic concerns rather than health risks, as TDS primarily affects the taste, odor, and appearance of drinking water. High levels of TDS can result in water that tastes salty or bitter and can lead to staining on fixtures and surfaces.

While the primary standards are focused on eliminating health risks from contaminants, secondary standards like that for TDS allow for maintaining quality and palatability of drinking water. Values exceeding this limit may prompt action or evaluation of the water supply to ensure it meets consumer taste preferences and quality requirements.
