How much TDS is good in drinking water?

Drinking water is flushed with harmful chemicals from the various water treatment plants. As a result, the natural minerals present in the water are also taken away. In such a situation, it is important to use the proper filtration processes to remove the contaminants and make water safe for consumption. TDS or Total Dissolved Solids are the main contaminants which are present in the water, and left in the water after the normal filtration process. A filter generally helps in removing TDS particles that are 0.45 microns in size and originates from different sources. The left out contaminants present in the water after the filtration process consists of charged atoms and ions. Moderate to high TDS levels in water can change the taste of water and pose a lot of health hazards. The most effective way to maintain the TDS level is by using the best water purifier for the home.

What is TDS in Water?

TDS Total Dissolved Solids in water means organic and inorganic materials that also include minerals and ions dissolved in particular quantities. When the water passes through stones, pipes, or even different surfaces, the particles get absorbed into the water. TDS in water can come from various sources like minerals and chemicals used for treating water runoff from the road salts and chemicals or fertilizers from the farms.

Why is it important to measure TDS?

Testing the water is the best way to check the quality of water which you receive and use for various purposes. Here are a few reasons why measuring TDS in water is important:

  1. a)     Taste – High levels of TDS range for drinking water can affect the taste. Water can taste bitter, salty, or even sulfuric, depending on the type of dissolved solids present.
  2. b)     Health Purposes – Water, which has high TDS, is completely safe to drink. However, there are some substances like lead or copper which can cause health hazards.
  3. c)     Maintenance of Filters – Water filtration systems can get affected by a high level of TDS. By testing water purifier systems regularly will also ensure that the filters are working properly.
  4. d)     Cooking – Although high TDS levels don’t affect health, they can alter food taste.
  5. e)     Cleaning – High TDS levels in the water will leave ugly spots on the utensils. This type of water also fades the clothes’ color and leads to a buildup in the sinks, tubs, and faucets.

Water, which has a TDS level of more than 1000mg/L, is unfit for consumption. The presence of potassium, sodium, chlorides increases the TDS level in the drinking water. However, the presence of toxic ions such as lead, nitrates, cadmium, and arsenic in the water can lead to a number of serious health issues.

Drinking Water TDS Chart

The most important question that many people have in their minds is the water’s acceptable TDS level.

TDS Level in parts per million (ppm)

Palatability Quotient

Between 50-150

Excellent for drinking

150-250

Good

250-300

Fair

300-500

Unacceptable

How Much TDS in Water is Good for Health

The table mentioned below provides a permissible range of TDS in drinking water and reasons on why TDS level is not acceptable for drinking:

TDS Level (Milligram/Liter)

Remarks

Less than 50

It is unacceptable as it lacks many essential minerals.

50-150

This range is acceptable for drinking. This TDS level is ideal for areas where the water is polluted by sewage or industrial waste.

150-250

The water in this range can be used for drinking and is also ideal for people with cardiovascular disease.

250-350

The water in this range can be used for drinking and is also ideal for people with cardiovascular disease.

350-500

The water in this range is fairly acceptable.

500-900

The water in this range is less acceptable.

900-1200

The water in this range is the least acceptable. Try to avoid drinking water that has a TDS level of 900.

1200-2000

The water in this range is not acceptable for drinking.

Above 2000

The water in this range is unacceptable for drinking.
