Do you know that the TDS value plays a significant role in determining the quality of your drinking water? Yes, it is a measure that indicates the number of chemical compositions and contaminants present in the water. If you live in an area such as Mumbai, India where the water TDS range is high, then it’s a sign of contaminants including heavy metals. A high TDS value of your drinking water does not only affect the quality of water but has adverse effects on your overall health.

This is the reason why managing the TDS value of your water is important. Well, if you want to know what exactly TDS is and why you need to opt for effective water purification to reduce TDS levels of water, then this blog is for you!

TDS is referred to as “Total Dissolved Solids’, which is a measure of the total concentration of dissolved substances, both organic and inorganic in your drinking water. Here, dissolved solids can be heavy metals, minerals, cations or anions, salts, and other contaminants.

High level of TDS in drinking water is caused due to natural sources of water, industrial wastewater, sewage, urban run-offs, chemical-based treatment or even to use of chemical fertilizers in plumbing or gardening. As water is a universal solvent, it can get impurities and dissolve them within it quickly. It makes the water taste salty and bitter.

Moreover, TDS also involves magnesium and calcium, these two minerals can lead to staining, scale formation, and water hardness. TDS levels also get elevated when huge concentrations of chloride, sodium, parasites, and hazardous elements are present in it.

Water TDS Range: What is Considered Safe?

Measuring the TDS value of water is crucial to know if the water is fit for consumption or requires purification if it has higher TDS levels. The TDS levels of water are measured by PPM (Parts Per Million). The water with a TDS value range between 50-150 PPM is considered excellent for drinking, 150-250 is good, 250-300 is fair, 300-500 is unsafe, and above 1200 means unacceptable. In short, the best TDS level for drinking water ranges between 50 and 150 PPM. It is considered acceptable and suitable for human consumption.

Understanding the TDS Range in Drinking Water

As per the Bureau of Indian Standards (BIS) – IS 10500:2012, which represents the standard for drinking water quality in India, the acceptable limit or the minimum TDS for drinking water is 500 PPM. This is essential to ensure that the drinking water you get at your home has a TDS value under 500 PPM. Also, it is important to check other parameters such as chemical and microbial parameters to ensure that the water is completely safe for consumption. Well, the TDS value may vary depending on the source of your water. The TDS value in borewell water is commonly higher as compared to the water you get from the municipal supply in Mumbai, India. It may range between 50-2000 PPM. The groundwater may have high water TDS range from 220 to 1050 mg/L.
