TDS Level in Drinking Water FAQs

The full form of TDS in drinking water is Total Dissolved Solids, and it is the measure of all inorganic and organic substances that are dissolved in water. The very common inorganic substances that are found in water are magnesium, calcium, and potassium. To a certain degree, the presence of these minerals in the water is actually healthy, but when the level becomes too much, it is a cause of worry.Why Do You Need to Check TDS?

By measuring TDS levels in the water, you will be able to make sure whether the water you are drinking is pure or impure. Do you know what is the maximum TDS level advised by the Indian Authorities? The maximum TDS level of drinking water is 500 mg/L. Whether you get your water from the nearby lake or a tank, you must make sure that it meets this mentioned level. If you see that the level is exceeding 500 mg/L, we suggest that you do not drink that water.

World Health Organization (WHO)reporton TDS in drinking water points out that reliable data on possible health effects associated with TDS in drinking water is not available.

You may also want to check out ourdetailed water purifier buying guideor the top list ofbest water purifiersin India.No health-based guideline value is proposed for the ideal TDS of drinking water. Because TDS in water can be high because of many factors, in areas where the TDS content of the water supply is very high, the individual constituents should be identified.

The Bureau of Indian Standards (BIS) has set the acceptable limit of TDS in drinking water at 500 mg/L. However, the standard also mentions that in case no alternative source of drinking water is available, then this acceptable limit can be relaxed to 2,000 mg/L. The BIS report also mentions that if the drinking water TDS is higher than 500 mg/L then this may result in a decrease in palatability (acceptable taste) and may cause gastrointestinal irritation.

The presence of dissolved solids in water may affect its taste. The palatability (acceptable taste) of drinking water has been rated by panels of tasters in relation to its TDS level as follows:

This acceptable TDS limit applies to only normal freshwater, if the water contains toxic impurities like arsenic or fluoride then other special BIS standards will be applicable.

It is important to note that some of the dissolved minerals in water are useful for human health and therefore very low or zero TDS is also not recommended. Reducing the TDS level to a very low value also affects thepH level of the water, which BIS specifies should be in the range of 6.5-8.5. Water with very low TDS will taste dull.There is no official lower limit, but TDS of at least 80 ppm is the accepted minimum level.

Reasons for Acceptability/Non-acceptance

Not acceptable. Because water with such a low TDS level does not contain the essential minerals.

Acceptable. However, the TDS level in the range of 80-150 is considered ideal. If you are using an RO water purifier then make sure the TDS level of purified water is not below 80 mg/L.

Acceptable. This is the ideal TDS range as far as cardiovascular fitness is considered.

Acceptable. Most urban Indian homes have access to water in this TDS range.

Acceptable. As per the BIS guidelines, a TDS level below 500 mg/L is acceptable.

Not acceptable. Use a RO water purifier with a TDS controller or mineralizer.

Not acceptable. Use a RO water purifier with a TDS controller or mineralizer.

Not acceptable and not fit for drinking. Choose a RO water purifier that can purify water with up to 2000 mg/L.

Do not drink. Most home water purifiers cant purify water with a TDS level over 2000 mg/L.

There are a number of methods by which you can measure the TDS level in the water. We have compiled some of the most common methods that you can use at your home to know whether or not you are drinking safe water.

This is a state-of-the-art digital TDS meter tester that you can use to check the performance of your water filter, test the quality of filter water, check for hardness and make sure that you are drinking clean water.

Digital TDS meters are widely available on all the leading online stores in India and you can easilybuy a quality Digital TDS Meter from r a few hundred rupees.

Follow the given steps to measure the TDS Level of water using a digital TDS Meter:

Turn the TDS meter on. You will find the ON/OFF switch is on the panel.

Immerse the meter into the water up to the maximum immersion level (2 inches).

Gently stir the meter to dislodge any air bubbles.

Wait till the reading stabilizes (approximately, 10 seconds).

Press the HOLD button and take it out of the water to view the reading.

If the meter displays the x10 symbol, it means that you have to multiply the reading by 10.

After use, shake off the excess water from your meter and replace the cap.

Watch this video on how to measure the TDS level in drinking water.

Do not dip the meter beyond 2 inches because the meter is not watertight.

Do not store the meter in places of high temperature or where direct sunlight comes.

Method 2: Using Filter Paper and a Scale

This is a conventional method that you can easily use in your home to measure the level of TDS in your drinking water. For this, you do not need any TDS meter, but very simple everyday things.

Step 1 Weigh the evaporating dish in milligrams and make sure that the dish is completely empty, free from any kind of particles. Note this measurement as A and come back to it after all the steps have been completed.

Step 2 Take the stirring stick and vigorously stir the sample of water in the sterilized beaker. You need to agitate the liquid so that the particulate matter present in the beaker gets evenly distributed.

Step 3 Take the pipette and collect 50ml of the stirred water. Please note that even while collecting the water, you have to continue stirring the liquid.

Step 4 Extract water from the pipette and pass it on to the filter paper 3 times. There will be some sediment left behind in the filter paper.

Step 5 If you see any particles in the filter paper, transfer them to the evaporating dish.

Step 6 Wait for the filtrate (particles) to completely dry.

Step 7 Once the filtrate on the evaporating dish is dry, weigh the evaporating dish again (with the filtrate) and call it B.

Step 8 Measure the TDS level by subtracting B from A.

To checkTDS level, use the formula:TDS = [(A-B)*1000]/ml

In this formula, A stands for the weight of the evaporating dish + filtrate, and B stands for the weight of the evaporating dish. Since 50ml was the quantity that you took in the pipette, the value of ml in this case is going to be 50. The final value of the dissolved solid is going to be measured in mg/L.

Carefully weigh the evaporating dish and also, the weight of the evaporating dish with the filtrate.

Wait for the filtrate or particles to completely dry before proceeding.

Most people often confuse the TDS level with water hardness. High TDS levels do not always mean that the water is hard. If you want to find out the hardness level of water then you shouldperform a water hardness test.

Always remember that a high TDS does not always necessarily mean that the water is unsafe for consumption. Sometimes it means that it may be a bit odd in terms of taste, color, or smell. Ideally, the TDS for drinking water must be below 300mg/liter and the maximum limit that is considered safe is 500mg/liter. But it should not be less than 100mg/liter for perfect health.

Water purifiers that come with reverse osmosis (RO) technology are a great solution toreduce high TDS levels in the water. These purifiers are built with cutting-edge technology to ensure that the TDs levels in water are reduced and that the water is safe for drinking. If you are planning to buy one, then you can check the latest range of RO water purifiers.

With the help of a TDS meter, you can even check the longevity and functionality of the RO membrane and replace it, if need be.

Share this information with your friends and family to equip them with the knowledge needed for checking the TDS level in drinking water. If you know any other way to measure TDS levels, please feel free to comment.

The Ultimate Guide for Buying A New Water Purifier

Top 6 Innovative Ways to Re-Use the Waste Water from RO Water Purifiers

21 Easy Tips on How to Save Water in Daily Life

My bore well water TDS level is 180. Is it safe for drinking? And there is a little bit of smell in the water too. Can I drink that water or not?

The TDS level is fine. The water is safe to drink as long as it does not contain any harmful heavy metals like lead, arsenic, etc. There can be several reasons for the smell. Are you drawing the water directly from the ground or is it supplied by a third party?

We are using Pureit Mineral Copper+ RO+UV+MF water purifier.

Yesterday the GKK2 kit was replaced.

The output water TDS is showing 35 PPM whereas the inlet TDS is 375.

The technician informed me that TDS level cant be adjusted in this purifier and its always output is 10% of input TDS.

There is TDS modulator which is connected after RO and before UV, its newly replaced. But if that works it should increase the TDS level more than 10%?

As per the WHO standard, drinking water below 50 PPM is unacceptable as it lacks required minerals and is tasteless.

Unfortunately the technician doesnt have any knowledge in this.

This purifier does not have any TDS modulator, therefore TDS cant be adjusted.

As per my water technician, the Aquaguard RO water purifier is showing 210 after testing with the TDS meter. Is it good for health or do we need to change the filter? Thanks in advance.

Thats a little higher than the usual TDS level of the RO purified water. What is the source of water and what is the TDS level of the incoming water?

Below 15 Tds is advisable for safe consumption

My borewell water TDS level is 650 ppm so I bought Aquatec water purifier. Now the TDS level of purified water is 20 ppm. Is this good? Please suggest me. Thanks.

My RO gives the water which TDS level is 98. Is it suitable for drinking?

As per BIS standards, you should ideally drink water that has a TDS level below 500 ppm. What is more important than the TDS level is the constituents of TDS. If your water contains harmful heavy metals like lead, arsenic, and mercury, then water with a TDS level of even 100 is unsafe. And if it doesnt contain any such harmful impurities then water with a TDS level of 500 is also safe.

There is no reason to worry, as long as you are able to meet the dietary requirements, for essential minerals like Calcium and Magnesium, with what you eat. Do you have a TDS controller in your water purifier? If yes, then we recommend adjusting the TDS controller to get purified water with TDS of at least 50-80 PPM.

Thank you very much for the information. TDS level is 5 in RO water and tap water TDS level is 95.

Now we are planning to alter the RO.

How do I know if the TDS meter is working perfectly? Is there a sure-shot way to know or verify its measuring accuracy?

I live in Gurgaon and one of the TDS meters I bought is showing tap water value as 94ppm whereas other people in the locality say that it should be much higher. Can I take some standard bottled/mineral water of some brand that has printed TDS to verify the TDS meter accuracy with it?

Sir have you ever used pg purifier, they said that pg purifier can filter water and save you from dirt, parasites, pesticides other contaminants and kills bacteria & viruses. Sir if you have used this before then tell its useful or not.

No, we have never heard of this brand.

My RO is showing 9 & tap water is showing 123 which is better for drinking?

My RO is showing 4 TDS value is it suitable for drinking & cooking, please suggest.

TDS value of 4 is extremely low. That means the water you are drinking is devoid of all essential natural minerals. What is the source of water?

TDS level of 9 ppm is very low and is not advised for drinking. Since you are having tap water supply and the TDS level of tap water is just 123 ppm, we suggest using a UV+UF water purifier instead of an RO water purifier.

Very helpful information. Thank you.
