Contaminant Guide
High TDS in Your Drinking Water
Total Dissolved Solids (TDS) measures all minerals, salts, and compounds in your water. High TDS causes scale, off-tastes, and can signal underlying contamination issues.
Key Facts
- • EPA secondary (aesthetic) standard for TDS: 500 mg/L
- • High TDS is commonly associated with a flat, bitter, or salty taste
- • Coastal SC and NC well water can show elevated TDS from mineral-rich aquifers
- • Reverse osmosis is the technology commonly used to reduce dissolved solids
- • TDS alone doesn't indicate toxicity — what's dissolved is what matters
The Solution
Reverse osmosis is the technology commonly used to reduce total dissolved solids in drinking water. ClearFlow installs under-sink reverse osmosis systems; reduction performance is defined by the manufacturer's published specifications and varies with feed water conditions.
