A good TDS (Total Dissolved Solids) level for water typically ranges from 250 to 350 mg/L. Water within this range is considered ideal for consumption, particularly beneficial for individuals with cardiovascular health concerns.
Understanding Total Dissolved Solids (TDS)
Total Dissolved Solids (TDS) refer to the total concentration of inorganic salts and organic matter dissolved in water. These solids can include minerals like calcium, magnesium, sodium, potassium, and bicarbonates, chlorides, and sulfates. While some dissolved solids are essential for human health and contribute to the taste of water, excessively high or very low levels can affect its quality and potability.
Recommended TDS Levels for Drinking Water
The palatability and safety of drinking water are often linked to its TDS level. Here’s a breakdown of TDS levels and their general remarks for drinking water:
| TDS Level (Milligram/Litre) | Remarks |
|---|---|
| 250-350 | Good. The water is ideal, especially for people with cardiovascular disease. |
| 350-500 | Fairly acceptable. |
| 500-900 | Less acceptable. The taste may become noticeable. |
| 900-1200 | Least acceptable. It is advisable to avoid drinking water that has a TDS level of 900 mg/L or higher. |
Why TDS Levels Matter
The concentration of dissolved solids impacts water in several ways:
- Taste: Water with very low TDS might taste flat or distilled, while very high TDS can give water a metallic, salty, or bitter taste. The ideal range offers a pleasant taste.
- Health: While some minerals are beneficial, excessively high levels of certain dissolved solids can pose health risks over long-term consumption. Conversely, water with extremely low TDS might leach essential minerals from the body.
- Hardness: High TDS often correlates with water hardness, leading to mineral buildup in pipes and appliances.
Managing TDS Levels in Water
If your water's TDS level is outside the ideal range, particularly if it's too high, there are methods to address it:
- Reverse Osmosis (RO) Systems: These systems are highly effective at removing a wide range of dissolved solids, providing water with lower TDS.
- Distillation: This process boils water and condenses the steam, leaving dissolved solids behind.
- Deionization: Uses ion exchange resins to remove ionized salts and minerals.
Monitoring your water's TDS level can help ensure it remains safe and enjoyable for drinking.
