The quality of drinking water is very essential to human health. One measure that has been used to establish the quality of water is known as TDS, or Total Dissolved Solids.

TDS represents the concentration of dissolved substances in water. These substances include minerals, salts, and organic matter.

In this guide, an elaborate understanding of drinking water TDS, its importance, impacts on health, and effective control will be discussed.

TDS in water means the total concentration of dissolved solids. Primarily, these are minerals like calcium and magnesium, but it also includes salts and trace levels of organic matter.

Usually, the TDS level in water is measured in parts per million (ppm) or milligrams per liter (mg/L).

Though some amount of TDS is healthy for the quality and taste of drinking water, excess or deficient amount of TDS in drinking water may have negative impacts on health.

The total dissolved solids (TDS) are dissolved materials within water that consist of both organic and inorganic materials.

Examples of dissolved solids include: minerals, calcium and magnesium - causes of water hardness, and salts include sodium chloride and potassium chloride.

• Metals: Lead, arsenic, and iron (primarily traces).

• Other Materials: Organic matter through decaying flora or industrial leach.

Dissolved solids dissolved in water though this is a naturally occurring phenomenon, but still, industrial, agricultural runoff as well as old pipes make the drinking water have some concentration levels of TDS.

The TDS level in drinking water is one of the major indicators of its quality. According to the World Health Organization and the Bureau of Indian Standards, the desirable TDS levels in drinking water are categorized as follows:

• Less than 50 Poor (without essential minerals)

• 50-150 Excellent

• 150-300 Good

• 300-600 Average

• 600-900 Fair

• 900-1200 Poor (not fit for consumption)

• Above 1200 Unacceptable

The TDS level in water is a balancing act. Drinking water with low TDS may lack essential minerals, while water with high TDS may contain harmful contaminants.

The TDS in water is influenced by several natural and man-made factors. Common sources include:

• Rocks and soil through which water passes can contribute to the TDS levels.

• Groundwater tends to have relatively higher TDS compared to surface water because of dissolved minerals.

• Farm runoff, which introduces fertilizers and pesticides used in farming into the water.

• Industrial waste and effluent contributes to higher TDS levels.

• Leaching of metal from old water pipes

• Water softeners and filters reduce TDS, and filtration techniques increase TDS depending on the process involved

The TDS content in water can have health impacts in that it either makes the water too diluted or concentrated.

1.Diluted TDS Content:

Low-TDS water contains minute traces of minerals, like calcium and magnesium, which contribute to healthy bones and cardiovascular health. Over a period of time, consuming water containing very low TDS will lead to the following problems:

• Electrolyte imbalance.

• Mineral deficiency.

• Dull taste, which may lower intake of water.

2. Higher TDS Levels:

Drinking water with higher TDS levels is dangerous to the health because of the existence of harmful pollutants. Some possible outcomes are as follows:

• Renal Damage: Excess minerals can overburden kidneys.

• Gastrointestinal Disorders: Sodium causes an imbalance in digestive activity.

• Toxicity: The existence of arsenic and lead, etc. heavy metals is toxic.

• Hypertension: The excess salt in water raises pressure.

Testing TDS levels is essential to ensure safe water consumption. TDS can be measured using a TDS meter, which gives an accurate reading in ppm. Here's how to test your water:

1.Fill a clean glass with water.

2. Dip the TDS meter probe into the water.

3. Wait for the reading to stabilize and note the TDS level.

It is recommended to check periodically, especially if you are on well water or living in an area known for water quality problems.

If the TDS in your drinking water is too high, you can do several things to lower it:

1. Reverse Osmosis (RO) Filtration:

RO systems are one of the best techniques to reduce high levels of TDS. They eliminate around 99% dissolved solids, including harmful pollutants.

2. Distillation:

Distillation is a process whereby water is boiled and steam formed is collected as water; most of the dissolved substances are left behind.

3. Deionization:

Deionization is the removal of ionic materials from water, which is quite suitable for TDS reduction.

4. Activated Carbon Filters:

These filters are very effective for removing organic impurities but may not reduce TDS significantly.

High TDS water usually should not be used to cook since it will add to the salt intake and spoil food flavor. It can deposit minerals in cooking utensils, too.

To govern the TDS in water to be consumed, every country has set a limit acceptable in drinking water. Health department as well as the respective country's government has made policies accordingly.

• WHO: Recommends a TDS level below 300 mg/L for optimal taste and safety.

• BIS (India): Sets the permissible limit at 500 mg/L for potable water.

Adhering to these standards is crucial for maintaining public health.

1.Low TDS Equals Pure Water:

While water with low TDS looks very pure, it often contains fewer essential minerals which make it bad for health.

2. All High TDS Waters Are Contaminated:

Not all the high-TDS waters contain contamination. For example, for less use, the water high in calcium or magnesium would be useful.

3. Boiling Water Lowers TDS:

Boiling water kills microorganisms but TDS won't decrease by boiling water.

TDS in the drinking water is one of the major criteria concerning the safety of that drinking water and the health benefits achieved.

Though some of the dissolved solids are advantageous to you, large quantities become toxic to your health.

So regular testing is combined with a proper filtration method such that the water, which you consume, will meet the required standards.

Balancing TDS levels in drinking water prevents diseases, enhancing the overall quality of life. Only use water that contains all ingredients in a balanced level and suitable for health in taste and safety.

In conclusion, understanding the Total Dissolved Solids (TDS) levels in drinking water is vital for ensuring safety and health.

TDS refers to the total concentration of dissolved substances in water, such as minerals, salts, organic, and inorganic matters.

However, both low and overly high levels of TDS would cause harmful diseases to the individuals.

For instance, this is mainly due to essential minerals such as calcium and magnesium contained within the mineral.

A healthy person, however, is needed to ascertain the suitable amount of dissolved minerals present within the TDS levels in drinking water.

The ideal range for TDS in drinking water should be within 50 to 300 mg/L and is considered safe for consumption since it optimally balances the minerals without affecting its taste or safety.

Water with a TDS of below 50 mg/L might lack essential minerals, and, eventually, deficiencies will appear in the body.

On the other hand, water with a TDS level of above 1000 mg/L can contain harmful substances like heavy metals, salts, and chemicals, affecting the health negatively.

High TDS levels in drinking water, especially from sources such as industrial waste, agricultural runoff, or the dissolution of toxic metals from old pipes, can be dangerous to health.

Some of the possible health risks include kidney damage, hypertension, gastrointestinal issues, and even toxicity due to heavy metal contamination.

Exposure to high TDS levels for a long time can also lead to the body's accumulation of harmful substances, which may contribute to chronic diseases.

However, water that has very low levels of TDS may contain low levels of minerals that the body requires for survival, resulting in mineral deficiency, especially when people consume poor-quality water.

In this regard, it might result in electrolyte imbalance and forces them to take more fluids to stay hydrated.

Regular testing of TDS levels in drinking water is an important practice to ensure that the water is safe for consumption.

Modern tools such as TDS meters allow individuals to easily test their water at home, ensuring that the water they drink meets safe and healthy standards.

For households with high TDS levels, solutions such as Reverse Osmosis (RO) systems, distillation, and deionization can be implemented to purify the water and reduce harmful substances.

The fact remains that different water sources include types such as groundwater, well water, and surface water that naturally have varying TDS concentration.

Various water treatment processes, for instance chlorination and filtration, also have impacts on TDS concentration.

Sometimes more treatment will be required to ensure removal of contaminants without losing necessary minerals in water.

In the conclusion, drinking water TDS impact on health is not a matter of minor consideration. While it is essential to have water with a moderate amount of dissolved solids for optimal health, both high and low levels of TDS in drinking water can cause a variety of health problems.

Knowing the TDS levels in your water and taking the right measures to manage it through filtration and regular testing will ensure that the water you drink is safe, healthy, and beneficial for your overall well-being.

Thus, regular checking of TDS in the drinking water is very essential, which will ensure that one consumes the water that helps maintain your hydration needs and your general well-being.

The ideal Total Dissolved Solids (TDS) level in drinking water is generally regarded to be in the range of 50 to 300 mg/L. This is a balanced amount of essential minerals, such as calcium and magnesium, without impacting the taste or safety of the water. Such waters have a TDS range within which they are generally considered safe and beneficial for use by most people. But again, the TDS content may vary with different water sources, and the preferences on taste may vary with people. Water with TDS content above 500 mg/L may start tasting salty or unpleasant, and values greater than 1000 mg/L can be dangerous with high potentials to have harmful contaminants.

Drinking water with high Total Dissolved Solids (TDS) levels can lead to several health risks, particularly if the TDS is caused by harmful contaminants such as heavy metals, salts, or industrial pollutants. Long-term consumption of water with high TDS may cause kidney damage, high blood pressure, and gastrointestinal problems. There are certain chemicals in the water with high TDS, which can accumulate inside the body and cause toxicity as well as chronic problems in the body.
