Water quality plays a crucial role in ensuring good health, and one of the key parameters used to measure it is Total Dissolved Solids (TDS). TDS refers to the total concentration of dissolved substances in water, including minerals, salts, and organic compounds. While TDS itself is not harmful, it significantly impacts the taste, quality, and safety of drinking water. In this blog, we will explore the normal TDS level in drinking water, its importance, and how to maintain it for safe consumption.
Whether the levels of TDS in drinking water is goof or bad depends on the type of salts and compounds present in the water. Levels of TDS not only change the taste of the water but can also adversely affect human health. In this article we have articulated for you what research shows so that you know about the levels of TDS that are considered good for health.
What is TDS in Drinking Water?
TDS in drinking water is measured in parts per million (ppm) or milligrams per liter (mg/L). It includes a mixture of dissolved minerals such as calcium, magnesium, potassium, sodium, bicarbonates, chlorides, and sulfates. These minerals are naturally present in water due to geological formations, but human activities such as industrial waste disposal, sewage, and agricultural runoff can also contribute to TDS levels.
Normal TDS Level in Drinking Water
The Bureau of Indian Standards (BIS) and the World Health Organization (WHO) provide guidelines for the acceptable TDS levels in drinking water:
- Ideal TDS Level: 50-150 ppm (Preferred for taste and health benefits)
- Acceptable TDS Level: 150-500 ppm (Safe for drinking as per BIS standards)
- Maximum Permissible Limit: 500-1000 ppm (May be safe but can affect taste and long-term health)
- Above 1000 ppm: Not recommended for drinking, as it may lead to health issues and affect water quality
Effects of High and Low TDS in Water
Low TDS (Below 50 ppm)
- May lack essential minerals, leading to demineralization
- Causes tasteless and flat water
- Prolonged consumption may result in mineral deficiencies
High TDS (Above 500 ppm)
- Alters the taste of water (salty, bitter, or metallic)
- Can cause scale buildup in pipes and appliances
- May lead to health concerns if containing harmful substances like arsenic, lead, or nitrates
- Excessive sodium can be problematic for individuals with hypertension or kidney issues
How to Maintain Optimal TDS Levels in Drinking Water?
- Use Water Purification Systems: Install Reverse Osmosis (RO) or Ultrafiltration (UF) systems to regulate TDS levels and remove harmful contaminants.
- Regularly Test Water Quality: Conduct periodic water testing to ensure it falls within the recommended TDS range.
- Remineralization: If RO filtration reduces TDS below 50 ppm, use a mineral cartridge to restore essential minerals.
- Choose the Right Water Source: Municipal water supply is generally within the acceptable range, but groundwater may require treatment.
Conclusion
Maintaining a normal TDS level in drinking water is essential for health, taste, and overall water quality. While water with too low TDS lacks vital minerals, excessively high TDS can cause health risks and appliance damage. UNISTAR AQUATECH PVT.
